[Take a look at Hong Kong VOD Demonstration]netvigator.com Each customer's home is equipped with a set-top box which comes complete with a handheld remote controller. Programmes are centrally stored in digital, compressed form on a video server. They are transmitted along telephone lines to set-top boxes connected to phone sockets and a television, activated only when there is specific call-up from the customer. The major components which go together to provide Interactive Multimedia Services (IMS) are as follows:- Video Compression Although it has long been possible to convert video information into digital form, the quantity of bits generated for analogue/digital conversion is formidable. It is the advent of compression technology that has greatly reduced this enormous amount of data into a more manageable size. Video Server The video server is actually a number of computers linked together, forming a high speed processing platform needed to store and deliver the vast quantities of data represented by compressed, digitised video. The Set-Top Box The compressed, digital video content is delivered via the telecommunications network to the set-top box, whose job is to decompress, decode and reconstruct the television signal into a form acceptable to an ordinary domestic television set. The Network Hongkong Telecom's digital network is responsible for making the connection between the video server and the customer's set-top box when customer requests access to the service. The network also carries commands input by the customer, e.g. programme selection, fast forward, pause etc. back to the video server. (C) Hongkong Telecom IMS Ltd. I took a peek at Apollo 31 ( Yes Houston, 31 ) For 8 HK Dollars. This technology may work!
