A newly minted standard, called scalable video coding (SVC), enables video streaming at multiple resolutions, quality levels and bit rates. The ability to scale video performance based on the end point is achieved through this relatively new technology called H.264/SVC (Scalable Video Coding) that not only compresses but also distributes the video stream.
The standard allows us to have layers of encoded video, and if we use intelligent devices, it can allow us do lots of other things as well. To understand the principle behind these intelligent devices, we need to look at how videoconferences usually work.
Today’s videoconferencing relies on fairly unintelligent devices at the edge, and intelligence in the core, which is also called a “mainframe” model. A multi-point conferencing unit receives streams of video from each participant, decodes them, combines them and re-encodes them.
The traditional approach of doing encoding and decoding in the core introduces delay. It also means that users all get the same data stream, rather than one suited to their bandwidth, window size and client. In short, transcoding in the cloud makes for lousy conversations.
The SVC architecture puts more intelligence at the edge and a specialized router in the core. In the new model, the router and each participant’s client work together. They tailor data transmission to each client’s demands. When a client shrinks the size of their video window, the router knows and as a result, sends fewer bits, less frames, or lower-quality video to that client without affecting everyone else. The router isn’t busy encoding, merging and decoding streams, but it knows about processing, window size and bandwidth, which it can adjust dynamically throughout the call.
The standard tells us how to decode. The method used to encode is a lot harder and is considered the secret sauce. The router is usually a 1RU, Linux-based quad-core computer that handles up to hundred-way conferences. It is usually sold as a subscription model for about $1,000 per HD port per year, which is cheaper than the traditionally capital-intensive spending around video conferencing. Video gateways that let “legacy” video conferencing hardware work with the new standard are also available in the market.
This technology allows us to get live, four-way web-based conferencing in which each participant may have different local settings from a high-definition video at 60 frames per second to a consumer-grade VGA connection to a notebook camera. And the best part is that a typical broadband connection will suffice for end users.
Television technology has always been moving ahead, today is no different. From black and white, to finally colour, the television needed a better upgrade than the quality that was available in the 1970’s! Today there is an even bigger reason to buy a Sony LCD TV with HD capabilities in the UK.
English law is making bold statements. The world is to go digital! And no it is not a product of the New World Order. It in fact is looking at peoples needs, and giving us more choice.
The problem with existing television’s and this includes Sony, is that that technology is becoming outdated, and does not meet our needs. We want more channels and more choice, but the existing traditional ways of transmission only allow so many channels to be broadcast at the same time. Without going into the technical details, if we consider radio, you only can have one station on and around a certain frequency. There is a limit!
With the incoming of digital technology, the possibilities are endless. Precision is the key, and digital allows stations to transmit on the exact frequency. With much more available channels, the only person who can benefit is you!
Everyone wants to best sound and picture quality. We want life like pictures, and here is where HD television sets are coming into play. Television sets are getting smaller thanks to LCD technology, and the Sony Bravia range of LCD TV’s are ones which can provide the latest features, while yet needing less space.
The Sony Bravia range of LCD television sets also has HD capability, so you can get the new technology of high definition in your home. Sony is also a well known brand. Sony electronics are long lasting, and are reliable.
One of the greatest reasons of choosing to buy a Sony Bravia LCD TV is that Sony was the one to introduce Trinitron to the world. This Trinitron technology which has been upgraded now to WEGA is one which took the world by storm. When it was released, it allowed us to have much better picture quality.
Does this say that Sony’s Bravia range of LCD TV’s is the best to buy? Not necessarily, there are many great brands out there. However, many can’t match Sony’s ability to create a winning television set.
Sony also has not just thought about bringing just another television to the home. Sony has been and continues to focus on what it terms ‘Sony Style’. Sony Style is Sony’s way of looking at creating a television set that not only does its job well, but also that it looks good in the home.
Sony has always been committed to bringing the world, the latest and best technology available. The Sony Bravia range of LCD television sets are just another statement of there ingenuity. With the laws making everyone go digital in a few years, in the UK, a HD TV set such as Sony’s Bravia range of LCD TV sets may be the best way to go.

A recent UK TV advertising campaign suggests that Sony Ericsson has high hopes for it new handset, the Vivaz. If the spec list is anything to go by, it certainly looks set to be popular. Its key features include touch screen navigation, an 8.1 mega pixel camera with the ability to shoot HD video, and Wi-Fi internet access.
The Vivaz utilises both vibration and ringing to alert users to incoming calls and messages, with the option to assign MO3 music files as ringtones. This allows users to customise their phones so they can hear whatever song they like when the phone rings. In order to achieve handsfree communication, both a speakerphone system and an audio jack are included, the latter of which accommodates both earphones for listening to music, and handsfree headsets.
An array of features is included as standard, which accomplish a range of everyday tasks. A versatile media player supports most common formats of both music and video files, such as MP3 and MP4. Alongside this, a stereo FM radio player is included, as is a selection of pre-installed games along with access to a library of additional downloadable games. Social networking fans are well catered for with Facebook and Twitter apps which offer a convenient method of directly accessing these sites. YouTube and Picasa integration is an impressive feature which allows photos and video s taken on the phone’s camera to be directly uploaded to these sites in seconds for the world to enjoy.
The Vivaz relies on touch screen technology for navigation of the Symbian Series 60 user interface. The 3.2 inch TFT resistive touch screen displays up to 16M colours within a pixel layout of 360×640 for high quality display of on screen content, offering great levels of detail and clarity. An accelerometer sensor is built into the screen for auto-rotate of the on screen content, so it can be viewed in both portrait and landscape forms. Another interesting feature of the screen is an accurate handwriting recognition tool.
Internal memory within the Vivaz is 75 MG as standard, which offers a good deal of storage for data such as music tracks, video clips or photos. A micro SD card slot is also provided for the same purpose, with a pre-installed 8 GB card. This can be upgraded, however, by installing a card of up to 16 GB in the card slot. This would provide enough storage for most people’s needs. The internal phonebook features the popular photocall function. This allows users to assign a photo to each contact. This is in turn displayed on the screen whenever that person calls or is called.
As mentioned, a powerful 8 mega pixel camera is included, which offers extremely high quality photos along with the ability to shoot gorgeous HD video. A TV out port means the phone can be plugged into a compatible HD TV so High Definition can be enjoyed in all its glory.
Both 3G and Wi-Fi provide fast internet connections dependent upon location, and class 10 versions of both EDGE and GPRS keep the Vivaz connected to cellular networks.
With such impressive hardware as well as software, it would be surprising if this exciting new handset was anything less of a hit for the manufacturer.
