Types of projectors and the technological developments in consumer electronics


There are two types of the display devices when considered from the point of view of the light that is projected on the screen. In one type of the device, which is also the most commonly used and widely prevalent one, like the TV, the images or the videos are projected from the behind  the screen on the front of the screen. The examples of these devices are the television, the computer monitors and a number of other similar items of consumer electronics where the projection is from behind the display source.  Then there are the other types of devices in which the projections from the front of the screen are developed on the screen. These devices which are used for the in-front screen image projection are called the projectors which can come in different types. 
The most common types of projectors are the cathode ray tube based (CRT) or the Liquid Crystal Projection (LCP projectors). The former are what you find in the cinema halls and at the public displays. They provide arguably the best picture quality of the size of the screen. The latter have more user friendly options. These are easy to set up, portable and can also some with the focus and zoom functions. There is one more type of the projectors which are used and these are the DLP ones. The digital light processing (DLP) ones make use of the thousands of the tiny mirrors to modulate the light and project it through the single lens on to the screen.
The projectors are used in different settings. These are used to give the presentation to a small or a large group of people in the conference rooms. It is also used for the large scale seminars where people find it convenient to make use of them to put for their view point and to share their opinions. These can be connected with the laptops with or without the wires. Their use in cinema halls is quite evident as well.
 The companies engaged in the making of the consumer electronics products are the ones which are at the forefront of making use of digital technology in developing the newer and better electronic appliances for different home and office needs. The convergence of the information, communications and the entertainment technology is more evident in the case of the new age smart phones. These are internet-friendly, enable the shooting of high resolution photos and videos and can, of course, be used for communications. These have evolved into the feature and function loaded mobiles which are of immense practical use. The companies like the HTC make the smartphones having elaborate functions and connectivity features.
The latest developments on the new product launches and their performance can be read on the online websites or in the product and technology magazines for the same. The consumer electronics reviews are a good source of information which can tell you about these developments and guide you on the purchase decisions.

The main noticeable trends in the consumer electronics industry


Consumer electronics refers to those electronic items which are to be used by people in their day today works. These items can be broadly classified into the categories of communications and entertainment. The former include the common place examples of the mobile phones, personal computers and many other devices which are used for communication purposes. The latter include the devices such as the MP3 player, DVDs, VCRs, and many more.  Even from a cursory look, it would look evident that these two categories cannot be held separate or distinguished from each other. There is a definite overlap of the functions of one category or the other.
This overlap is called convergence. So, you do have a computer which is used not only for communicating or gaining some information but also for entertainment. Similarly, you can have the HTC and the mobiles of other companies, called smartphones, which are used not only for communication but also for the entertainment like listening to music. So, the convergence of the technologies has been the main trend of the consumer electronics industry for the past decade or so. There has also been a definite improvement in the quality of the output of the devices as well which has led to their improved performances. The ushering in of the high definition performance levels, the improvements in the display and the audio technologies and many such trends have also been a marked feature of the entertainment industry. These trends, coupled with the mixing of the trend of convergence, have it possible to have the systems like the home theatre systems which can deliver the excellent output in terms of the audio and the video capabilities.
In the field of small as well as large display technology, the aim has been to make the products more practical, user friendly and with better viewing quality of the pictures and the videos. This has been sought to be achieved by the making of the flat panel displays with the LCD or the LED display technology, better resolution levels, better aspect ratios, better contrast ratios and many more improved features. The same technology is being used for the computer monitors, televisions and many other devices where the lighting is to be done.
For the audio part, there have been improvements in the technology of the storage mediums like the CD/DVD/blu-ray discs, the players like the MP3, the audio output devices like the speakers and a number of other control devices like the amplifiers, modulators and many others.
Connectivity among the electronic appliances with or without the wired connections has been another noticeable trend of the consumer electronics industry. Even within this, the trend has been more towards the wireless connectivity. The use of the wi-fi technology for the internet connectivity, the blue tooth connectivity between the devices has enabled more flexible operations of these devices by the users.
So, the technological convergence, improvements and connectivity have been the main noticeable trends of the consumer electronics industry.

User-focused music entertainment systems use latest and best speakers and headphones


There is a lot to the music entertainment at home than simply having a musical device. There is a whole lot of instruments which can give you the best quality sounds and, at the same, time offer convenience of operation as well as usage. The quality of the sound given out is dependent on not only the musical devices as such but also on the accompanying speakers, the connecting cables or the wireless connectivity, the quality of the headphones used for the purpose of listening to the music and also on the surroundings.

The surroundings also hold a lot of importance for the acoustics since the reflection of the sound waves and their absorption also play an important role in the delivery of excellent sound quality, especially in the home theatre systems. And, it is not only the homes which can be made into the chief entertainment places. The present gadgets have made it possible to make entertainment an everywhere experience. You can have the MP3 players downloaded into the computer systems where you can use the same to play and listen to music while you work. The same can even be had in your mobiles and ipods which make it possible for you to have the music treat anywhere you go. The cars or the automobiles are also fitted with the musical devices along with the speakers placed at the right places.

The technological progress has not only enabled the development of the advanced music systems but also focused on the audible systems. The audibility of the sound systems with the headphones has undergone marked change since these have been able to cancel the noises of the surroundings to a great degree to give crystal clear audible experience. What is even more promising for the future is that the efforts to make wireless headphones have made considerable headway. So, you do not have to remain tied to one place if you do not want to disturb others with the sounds of the music. You can very conveniently make use of these devices to listen while you carry out your other works.

The inevitability of the music entertainment for the special occasions, parties, discotheques and others also means that the turntables become an inevitable part of the music systems as well. These turntables are used by the disk jockeys for the mixes of different types of music and songs to give an enjoyable experience to the people. The quality of the music delivery can be improved by keeping all the furnishing which is sound-friendly and able to give you the best listening effect. The high wattage speakers placed alongside create the electrifying environment along with the lighting effects.

So, whatever be the genre of the music which you want to play, the music system shall be able to deliver the pleasant sound experience, shall be convenient to use and for this purpose, it shall be making use of the latest versions of MP 3 player, speakers and headphones.

MP3 players make musical treat possible everywhere


Entertainment, musical or otherwise, is sought by people whenever they feel the need to rejuvenate their minds, re-energize their bodies and relax their minds. The everyday burdens and tensions of life, at work or at home, are sought to be done away with by listening to the music. It is one of the greatest means to motivate yourself when your chips are down or things are not going your way. For meeting these various needs of the people, the companies are devising the newer means and devices to provide easy access to quality music to the people, wherever they are. The MP3 players, in all their forms and formats, have been instrumental in meeting this need.

Their miniature size, the large storage capacity of keeping hundreds or thousands of music files and the ease of carrying the same have made the MP3 player the hot favorites of the music lovers. The difference and the relation between the MP3 file and player shall be understood clearly. The MP3 can be a file format of the music file and the MP3 player is the physical device which can run either the MP3 file format or some other music file formats.

The MP3 players come with the accessories to give the best sound quality. These can be attached with the outside speakers to produce sounds and the music can be heard by everyone. However, if you want to make use of these players for private individual listening, you can use the headphones for the same. These do not produce sound on their own and have to be used with the speakers or headphones. These devices are essentially meant for private listening while doing the various activities like the jogging, walking, or even doing some routine repetitive works.

The MP3 players can be played in different formats. The files can be downloaded in to the computers from the websites. The same can even be downloaded into the mobile phone that supports the MP3 file formats. There are also the physical devices which can be used to deliver quality sound output. There have been innovations in the development of the accessories as well. The trend is towards the development of the wireless headphones which will obviate the need of the users to remain glue to one place for listening to a device. With wireless technology, the music can be listed to while moving about.

While these innovations have changed the way individuals listen to the music, the changes are also being brought into the public music entertainment. The turntables, used for providing musical extravaganza to the parties and functions, are also using the better quality instruments for playing the music and the high wattage speakers with suitable audio controls to provide the right quality of the sound. These are helpful in suitable mixing of the music to make he people enjoy the fun and dance during the parties. So, there is an all round improvement of the systems to produce and deliver the quality sound for individuals as well as for the parties.

Do appliance reviews serve any purpose?


Appliance reviews about the different items of consumer electronics, whether for entertainment or for doing some specific tasks, are on of the most read about ones. Some read these to keep in touch with the latest development on the technical front. Some read these since they have to buy one or more of these. And, some others might be reading these only for the purpose of telling others how much you know about the forthcoming product.

However, if you are reading about the appliance reviews, here are some of the things which you shall keep in mind:

  1. Read only from the authoritative site or source. This is a crucial factor to be considered when you are using the internet medium for referring to the reviews of any particular product. The authoritative site shall be able the one which provides the truest and the correct information. These sites do make sure that the reviews are genuine and not fictitious.
  2. Check for the balance in the review: Some of the reviews which are tilted too much against or too much in favour of something could be wrong or given by someone who is either maligning the product or by someone who favours the same. The reviews which are balanced in nature are a safe take.
  3. For products like the video cameras or Nintendo Wii gaming console, it is good if the reviews are given in the video format which can enable a person to check the quality of the performance. So, it is better to have the appliance reviews in the form of not just the text documents but also in the form of the videos for the performance driven equipment.
  4. Check for the review on more than one site: The review can be checked on more than one source to determine what si the right opinion.
  5. Check for the patterns in the reviews: When someone continuously keeps giving the bad reviews about the product and therein you can find the positive reviews coming all of a sudden, then it could be a very well considered part of saving the reputation of the product or the firm.

If you watch out for all these patterns, You might e able to make out whether the review is truthful or genuine or not.

For some instruments like the cordless phones, it may not be possible to review the performance in all respects since it is related to their audibility and their performance levels can be known only for the part which can be seen, not for the ones which is to be heard. Therefore, you have no option but to depend only on the reading of the appliance reviews.

These reviews can help you in your buying decisions. Which product you want to buy can be fairly hinted at by these reviews, though you might be willing to save the final judgement on the buying after seeing the product in the real.

There are different buying patterns and behaviours of people. They might down straight to the store, enquire a few things about the product and then either take or leave the same. They might also hop from one store to another to draw out comparisons and then select one of the products. Some of them can also first seek the opinion of their friends, family and peers to assess what is the right product to be purchased. There is also a section of people who closely keep a track of the products which they want over a period of time and check for the newer and improved ones. The appliances reviews are read from the newspapers, magazines and even the internet to get to know the details about the products.

They might make themselves more knowledgeable about the product by reading these appliances reviews but there is little they can do if their kids wants nothing but the Nintendo Wii gaming console. So, decision making is not completely rational. It is also guided by the pressures of the others. Nonetheless, the appliances reviews are important. These do tell about the functions, features and performance of the products. These can also be comparative reviews. The comparative reviews are done by taking the different products of same product category, preferably of the different but popular brands, and assessing their features, functions and performance simultaneously.

The people are provided these reviews by way of the video, audio or in the text formats. In the video format, you can make use of the websites as well as television for the same. The video format is the best way to show the performance of the products like the video cameras, mobiles and many others. The only audio format is not used widely for these types of product since the people would like to see the things as well. Even if some of the products are meant for listening like the phone sets or the cordless phone, their reviews are best watched or their audibility be heard in real. The reviews in the text format are present in the newspapers, magazines and even on the internet sites.

Internet has made it far easier for the people to find or search for what they want at a local or a global scale. Now they can find the products at the click of the mouse and can even find the credible sources of the reviews which can provide the authentic reviews of the same. So, the internet based review sites can be used for sifting through a number of different reviews, which is a key limitation of the other visual media-the TV.  The TV reviews programs can at best take some of the reviews only but internet appliances reviews can be many, coming from different users. Further, these reviews can be taken from the people at a global level. Then there could be independent opinions of the experts. So, the reviews can be coming from different people and could be of different nature, but sufficient enough for you to take a stand on the same.

From sat nav to entertainment: technology serves communication needs


There is not doubt that the electronic entertainment industry has seen some of the most far reaching and interesting changes in the technological spectrum in these years. The LED TVs, blu-ray disc players, hi-fi music systems and many other instruments give you a real life and totally vibrant ambience live with excellent picture quality and top audio quality. The companies like Samsung have had a major influence in guiding the technological research to make the users more convenient while operating, managing and using these devices.

While most of the common users are enthused at these marvel creations, what they conveniently ignore while appreciating these modern devices is that the accompanying accessories have a major role to play in the delivery of the excellent output. What they do not realise is that it is not just the music player or the high definition TV from Samsung or the smart phone from HTC which is good in itself, but it is also the connecting cables, the remote control, the speakers and the headphones and the likewise which are equally important as well. Has it not been for these hi end accessories the desired output would have had limited effect or impact on the performance of the instrument. So, if you are appreciating the picture quality of the LED flat screen TV, it is also because of the connecting high definition multimedia interface (HMDI) TV cables which make it happen so.

This does not mean that if you are connecting a number of devices together, it would lead to a wired mess in the room. The HDMI TV cables reduce the need of multiple wiring, thereby preventing the occurrence of the clutter since one wire can run through multiple devises without affecting the performance of the devices. The TV channels can be beamed from the satellite directly to your home with the help of a receiving antenna which needs to be positioned at an adequate angle to the sky. The signals can come direct to the antenna and the same are then transmitted through the cables to the TV.

The technology obviates the need of a cable services provider. The beaming of the signals to the TV takes a cue from the GPS technology which is used to continually connect to the objects, moving or stationary, with the satellite to determine their position. In this case, it is not the sat nav which is desired but the continuous beaming the of the communication signals to the stationary antenna.

Sat nav itself is being increasing used in the modern day applications which require the determination of the locations. This is the being used to manage the fleets operations, the cars and even the human being. These can be fixed in the cars or the vehicles and can even come in the mobile handsets of the people. So, the same satellite can serve both the navigations and the communications needs of the people. The technology is there to enable the common man to reap the benefits of both of these.

Do not ignore the importance of accessories like speakers while selecting the entertainment devices


Have you ever paid as much attention to the accessory items for the audio-visual devices as to the devices itself? For most of you it is certainly not the case. Most of you would just be interested in knowing what new product the companies are bringing out without knowing what are the best conditions to get the best performance out of the same. You arte more interest in the sound quality of the speakers and the music systems, not much in the connecting wires which support this infrastructure. You are more interested in the performance of the large LED TV but not in what all connections or power drive it to the best.

These things are taken for granted. The companies do not insist on the buying of the accessories by the customers even while they would advice them that the best performance would be achieved only in these conditions. The decision is left to the uninformed customer. The appliances reviews are read, but not the accessory reviews. You might be scanning every space of the product advertisement and medium which features this to know what the appliances reviews tell about the same, but hardly would you sit in front of the computer or sift through the columns of the newspapers to determine what the accessories manufacturers are doing or what are the different types of accessories available with a product.

This is not surprising that only the people directly connected with the entertainment devices know the importance of these devices. The Bowers and Wilkins hi-fi speaker phones and headsets are as important as are the Sony or Samsung music system. A truly great audio-visual experience of a home theatre can be had only if the accessories are able to support the same. What will the HD TV do if there are no HDMI cables to support the connectivity? If some other lesser variant is used, you will not be able to get the right picture quality, there might be breakages in the streaming of these videos and the quality will be affected.

A quite and underlying revolution is sweeping through these products which provide the crucial backbone support. With wireless technologies in the offing, like the blue tooth, the same wireless technology is being used to make headphones and newer products. It may not be entirely possible to deliver the best quality in the headphones due to noises and local disturbances, the technology is showing the way to future. The same is also being seen even in the projectors which can be connecter wirelessly to the computers.

You can gather a lot from the websites of the companies making these products, or you can even refer to the third party independent appliances reviews of the same.  These are the reviews which are read by the people to know not only what is the new product in the market but also what are the supporting accessories which can add to its performance level.  You can even keep your updated on the companies like the Bowers & Wilkins which make these products.

Making Merry in car using the car entertainment equipment


People like to get themselves entertained. Entertainment shall not be confused with ‘recreation’ since there is a perceptible difference between the two. The former is a type of amusement where the person does not participate directly in the amusement. He merely watches or hears the same but is not doing it. Whereas, in case of the latter, the person getting the amusement is a direct participant in the action. Since a person does not have to be actively engaged in the action for getting the entertainment, he can have the same at any place. Therefore, he can have car entertainment and even at home office or outside, even while doing any other activity.

Car entertainment can be had by means of the audio or the video formats. The audio form of the entertainment can be had by playing of the digital radio, magnetic cassettes and compact disks. The video form of entertainment can be had by using a small screen television which is connected with an antenna installed on the car, or even a movie can be played using the CD or DVD. The systems provide a very good audio-visual quality. The video car entertainment is usually done in the private cars, not meant for public use like the taxis whereas the audio entertainment can be had in both types of vehicles. If the taxis are being used for the public, then the entertainment shall be used with their due permission.

The car entertainment systems can be categorised broadly in the following categories:

  1. Overhead Flip down systems: These can be fixed on the inside ceiling of the car and the video screen can be made to hang down. These are a very good source of entertainment for kids who would be busy sitting on the back seat and watching the DVD while you drive on without any worries or hassles.
  2. Headrest systems: You can have the monitor of the TV screen in the head rest of the car seat in the front so that you keep sitting back and enjoy the DVD or the mp3 player being played in front of you.
  3. Car In Dash Entertainment Systems: You can have the digital radio or the CD player or the small monitor and the GPS systems inside your car dash board. These are used for entertaining people sitting in front seats of the cars.
  4. Portable car entertainment systems: If you do not want to get any of the devices to be attached to the car, then you can have the portable car systems for entertainment in your car. These systems can have a little bigger screen than what the other car-fixed devices have. These provide excellent quality images since the digital transmissions are of very good quality.

Besides the good quality audio-visual main devices, the car also needs to be fitted with the good quality accessories as well. These are the speakers, woofers, cables, headphones and many others.

Entertaining while moving: Car entertainment gives total experience


Modern entertainment technology has entered our homes, offices and even our automobiles like the cars, SUVs, RVs and others. This has been the result of fast growing technologies of the audio-visual systems and their accessories. Now, you can have the home entertainment systems in the form of home theatres as well as the car entertainment audio-visual systems to keep you entertained while you are on the move.

There are different types of car entertainment systems present in the market. These could be the ones which can be fixed with the ceiling of the car and the video can be hanging down. You can insert the CD or the DVD in the device close to the ceiling of the car. The second type is the one in which the monitor can be fixed in the rear of the front car seat headrest. The monitor can be fixed in the headrest so that the person sitting on the backseat can entertain himself or herself as per his wish. Yet another way could be carrying a portable entertainment device along with you whenever you have to travel in the car. This is very helpful if you are going for a long drive to some distant location or when the car is not your personal one. Using these, you will be able to play your own favourite songs or DVDs. One more variant of the car
entertainment system is the one which can be placed or fixed in the dash board of the car system. This is the one which is used for the entertainment of the front seaters, though it could be a little distracting for the driver.

The entertainment could be audio or visual. The digital radio or the CD player or the mp3 player gives you the audio entertainment whereas the DVD players are used to give you the video car entertainment. If you wish to buy one of these systems, you shall know what the precise entertainment requirements are and even check for the quality of the accessories to be used along with it. The accessories do influence the quality of the performance output of these devices.

What are these accessories which have a bearing on the quality? These are the car speakers which can play all the right tunes for you, the car sub woofers that control the element of bass in the sound quality, car tweeters for clear high frequency sounds, car amplifiers to modulate sound parameters and different types of listening devices like the headphones, global positioning systems and the radar detectors. The last two are more of utility features than the entertainment ones. These car entertainment instruments and the accessories give you a pleasant and entertaining journey wherever you go. You can have your kids or even the toddlers seated back watching the videos or listening to the sounds while you drive comfortably. Even the taxis use these for entertaining their customers during their journeys.

Benefits of reading the mobile phone reviews and other reviews


The technological leaps in the electronics industry have always sought to make things easier and better for man. You can know about the latest developments on the modern electronic devices and equipment by reading through their product features and the first hand reviews about the same. There are different sources from which you can gather information required for the same. These could be the magazines and the newspapers in the print media or the internet resources in the form of websites of the companies selling these products, like the website of the Asus or Sennheiser, or the review sites where these types of products are reviewed on different parameters. Further, the review resources could be based on the single product reviews, like the mobile phone reviews as well as the multiple product review sites.  

But why shall these reviews be read, or why shall these be given about the product? If you would go to buy any of these modern gadgets, these are bound to have some bearing on your pocket. If you are going to spend a couple of hundred or thousand dollars to buy these, you must know about their performance standards. It is not the features which you would like to know about in the reviews since these are already there on the company website. You would be more interested in knowing the performance levels of these gadgets. 

Have you listed down the number of companies which are making a particular product, say the projectors? This is going to be an arduous task since there bound to be a number of companies. This is not true only for projectors but also for a number of other products as well.  Then, there are a number of products within a product range. So, these products have to be compared for their features, performance and prices. The reviews can solve this problem. There could be independent product reviews or the comparative reviews of more than one product. Reading through these can bring to light the differences in their respective performances.

You might find it interesting to know that even the manufacturing companies of these devices like the ASUS or the Sennheiser, do read the customer reviews about their products. However, for this purpose, they take care to make use of only those product review sites which are very genuine and truthful about their work. These are the inputs for them to improve their products, to determine what all is desired by the customer and whether the product is able to deliver the same or not.

These reviews can be done by the customers and even by the experts. It is important to refer to the most authentic review sites for the same since there is also a good chance of the reviews being fudged. Referring to more than one source for the same can reduce the chances of being misled.

So, the mobile phone reviews and other product reviews can inform you better for aiding better decision making at your end.

Projectors too move ahead on tech front, offer great audio-visual experience


The present day entertainment experience comes with unmatched audio-display technology synergies. The development of technology in the audio sound systems as well as the display systems has redefined the entertainment experience of the people. The amazingly large but flat and slim TV systems with their high definition functional performance and path breaking display technology have been a major influence in the entertainment. The LCD/LED display devices give a better resolution and contrast ratios. The technology sweep has also extended to the 

projectors   not just confined to the on screen technology changes for the display devices.

The projectors are the devices which stream the pictures or videos on the screen in front. These are used by the organizations for holding the meetings, presentations and even seminars and conferences. These devices are also used in the cinema hall to entertain the spectators. For some organizational uses, the modern day projectors can be connected with the computers with or without the wires.  You can prepare your presentations or even run movies on the  ASUS laptop and then use the projectors to stream the same to a screen in the front.

The innovations in the audio systems have been far reaching as well. The improvement in the instrumentations and the technology has led to the development of high quality sound producing devices. The same can also do the variations for a number of different types of sound like the surround sound effect, the woofer effect, etc. The Sennheiser wireless technology has also led to the evolution of the wireless headphones. These headphones come with a base station which is essentially meant to transmit the sound waves to reach the speaker within a specified range. So, these have enabled the person to keep doing the work even while listening to the music.

The combination of the audio-display technologies has led to the emergence of new entertainment systems which were earlier employed only in the public places. So, now you can even have the theatre like experience in the home with a so called ‘home theatre’ system which comes with a sufficiently large sized screen, the music system, blu-ray disk player, the amplifiers and a number of other devices which can help you give the desired output.

There are a number of players in the entertainment industry market which are offering these products. So, if you go to buy any of these, it is better to do some research in the internet for the different products on offer and for what all purposes. You can find their comparatively analysis on the site. You can even read some of the reviews of these products. The reviews shall be read from some authentic sources only and a couple of the sites shall be referred for the same. The mobile phone reviews and other reviews can be read from the print media like the newspapers or magazine, through the electronic media like the TV or the internet resources. With TV and internet, you can even have the visual display of the reviews which can show up the true performance of these devices.

Fast changing display technology: From CRT TV to LED TV


There is always a debate on whether the new products are better than the older ones. Since the technology had advanced, there is definitely more to argue in favour of this argument, than against it. This debate has been ranging for all times and for all the things that are new. The people who are averse to change, at least till the point that the new things become very common and the old ones are near to be discarded, will habitually compare the new with the old. One such comparison has been that of the display devices like the TV.

TV technology has undergone considerable change. This has made a considerable impact on the size, design and the shape of the TVs, not to speak of its numerous new features and functions. The movement of the TV technology from the CRT to the tube-less LCD TV has been quite a long one, considering the pace of the subsequent technology changes. From CRT to LCD, the TVs have become slimmer, thinner, flatter and easy to carry. Not that the CRT ones have been thrown into oblivion but only that their sales have been taken over by the LCD TV sales a few years back. This obviously means that people are fast changing the track and coming on the new, supposedly better display technology. Since the CRT TV does not have depth and can be really slim, it means that these are more practical to be used, attached to the walls, kept on the cabinets and even made into the home theatres.

The LED TV is a further improvement of the technology. From LCD to the LED, the change brought about by the change in the backlighting device gives the users a better viewing experience. The contrast ratios are better, the display screens become wider, the TVs become even thinner, viewing from greater side angles is possible and there is some improvement in the power consumption also. Despite these advantages these have not been able to beat the LCDs because, being a new technology, the LEDs are prohibitively costlier for common people.  Further, the LED TVs generally come in wider screens, much bigger in size than the normal LCD TVs. This also limits their practical, daily use.

Companies like Sony are devising ways and means to bring down the costs of the LED TVs. The companies at the forefront of the technological research in the consumer electronics always keep in mind the practicality and the utility of the new devices which are developed by them. The companies continuously keep bringing in better innovations and the pace of these innovations is so high that the moment one technology is seen and understood by the common man, the new one comes up to replace it. This is quite evident that while the LCD TV has taken over the CRT TV in global sales volume now, the LED is yet to establish itself completely in the home and offices of the people, the new technology SED TV is knocking on the doors. There are many parallel running technological changes as well, like the plasma TV, OLED TV and others, from which the users can make a choice.

Changing technological horizons of the display technologies


There is a lot of craze among the people for the new audio-visual devices which can give them better viewing and listening experience. The technological leaps have been small and gradual, but very fast paced. This has led to change in the technological horizons of the display devices. Companies like Sony and others have been at the forefront of bringing these changes to the homes and office of the people.

If it were not for the light emitting diodes, the LED TV would be same as the LCD TV. The latter makes use of the liquid crystal display technology for displaying the images and videos on the screen whereas the former makes use of the light emitting diodes for the backlighting purposes. The LED TV is considered to be technologically superior to the LCD TV and capable of giving a far better viewing experience. Both of them are more practical innovations to the older cathode ray tube based bulky TVs.

Some of the main features of these new age TVs are:

  1. These are more practical in the sense that these can packed easily and can be fixed on the walls. This might seem to be a bit unnoticeable point but has great utility in areas of limited space. This is possible due to the sleek and slim designs of these TVs. The old CRT TV was quite bulky, had more depth which limited its placement on some cabinet. This also caused hindrances to the movement of people.
  2. These LCD and LED TVs from reputed companies like Sony and others support the high definition features of the images and videos. This means that if the videos have been shot and recorded with cameras having more than 2 MP resolution levels, then these can be seen on these TVs with good deal of clarity.

The LED technology is considered to be a shred better than the LCD TV technology mainly due to better contrast ratios and wider viewing angles. The backlighting in the LED gets switch off in the darker or black regions of the image which improves the contrast ratios. Further, if you view the screen from some angle from the centre of the TV, the viewing is better in case of the LED TV.

The improvement in the display technology has resulted in the making of these TV sets. The LED TVs are very costly and this is the reason for their limited entry into the drawing rooms of the people. The OLED TV, a further improvement over the LED TV does not require even the backlighting. It makes use of the Organic light emitting diodes for this purpose.

The researchers at top companies of the world, like Sony, are always working on newer technologies to further improve the display technologies and devices. This improvement is now sought to be introduced in the SED technology. This is believed to hold a lot of promise for the future since it combines the best of the old and the new technologies.   

Mobile Voip, Hi Fi Speakers, Cordless Phone: The Future Is Wireless


The pace at which technology is progressing, you will soon find most of the gadgets being run without wires. Finally, there is will be a respite from the wires, if not completely, then to a considerable extent. And, this revolution is most widely evident in the communications industry. Whether it is the simple cordless phone or the remote control being used to operate the different electronic items, the wires are fast becoming a thing of the past. Within the telecom sector, the ushering of the mobile telecommunications has provided round the clock accessibility to the phones by the mobile users.

Another important development in the telecom sector has been the emergence of internet based telecommunication, also called the voice over internet protocol technology. This allows you to make calls to people anywhere in the world for very less charges. Since the calls are routed through the internet wires, skipping the routine lines, the charges for the calls are very nominal. The same software can be loaded in the computer and calls be made from it using a pair of headphones, or the instruments can be attached with the computer systems and the calls be received on these. The VOIP software can also be downloaded into your mobile phone set and the calls can be made from it using the internet connection provided by the service provider or the wi-fi connection of your wireless local area network (WLANs). Companies like Netgear focus exclusively on these networking platform development.

The benefit of the mobile VOIP telephony lies in the extent of its reach and flexibility of operation. With a VOIP mobile or cordless phone in your hand, you are not bound to any location and the same can be used to talk incessantly at very low rates with the people living in other countries. If the call receivers also use the same software, then the calling facility could even be free of cost, the only charges being the internet usage time. You can use the voice over internet protocol to set up the call forwarding, call diverting, sending of files from your computer and video conference with the people at the other end.

The revolution towards the wireless technology can also be visible in the entertainment appliances. The remote control of the TV and the video was one of the earliest and the most common wireless device that was used to operate the electronic gadgets. Nowadays, you also have the same remote used to operate a number of different devices which are themselves interconnected with blue tooth technology. You can also have the hi fi music speakers as well as wireless headphones to listen to the music. With all these wireless gadgets you can reduce the clutter of the wire mesh that could be created by using so many electronic appliances. Further, these allow ease of operation and flexibility of usage of these devices as life is sought to be made more simpler.

Mobile VOIP telephony brings in a new age of video telephony


There have been three landmark technological developments which have set the revolution going in the information, entertainment and communication fields. It is a convergence driven by the zeros and the ones and this is called a technological convergence driven by the digital revolution. One common thing binds all the different audio-visual and other electronic devices together and this is the digital technology being used in all these devices. Another notable development in the technological change is that there is an increasing movement away from the wired devices to the wireless devices and their interconnectivity through the wireless medium. The cordless phone is the example of wireless connectivity seen quite commonly. Even more common is the use of mobile. The third important development has been the emergence of internet and the vast improvements in its ability to carry the data of all types like audio, video, text and the images. The use of the now common VOIP technology has enabled the long distance telephony to be made without incurring much cost.

The modern day hi fi telephony using the VOIP technology has meant that these systems can be used in the homes to talk to the near and dear ones living in the other countries, or that the businesses can benefit a lot by reducing their telephone bills by using these systems. At home or in office or even while you are on the move, you can use the voice over internet protocol phones through your computer systems, or through the normal telephone or even through your mobile. You do require an internet connection for making these calls.

The organisations commonly employ the VOIP PBX systems to manage their telephonic communications in a better way. The same can be used for managing multiple tasks, like call diverting, routing, forwarding, sending emails , faxes, instant messages, SMS messages ad many others. There is now an increasing trend towards the PBX systems being hosted is some other location where its maintenance responsibility is given to a third party. 

The leading telephone manufacturing companies of the world as well as the networking companies like the Netgear have been introducing the newer phones which are designed for use with the VOIP technology. The new range of cordless phone allows you to move around the space even as you handle international calls. The leading Voice over Internet Protocol service providers have been redesigning their software so that the same can be used in the mobiles for internet telephony purposes. The mobiles can operate in the presence of an internet connection either from Wireless Local Area Network (WLANs) or from the telephony service provider.
You can connect with your mobile on a video chat with the other person and even take a conference call on it.

These hi fi systems employing the VOIP technology are the examples of the progress made in the instrumentation and software applications development. The accompanying progress has also been made in the accessories for these instruments to deliver crystal clear audibility and the perfect picture quality.
