System and apparatus for supplying audiovisual information to a subscriber terminal

摘要

A system and apparatus for transmitting audio and video information to one or more subscribers terminal from a server. Each subscriber terminal includes a storage unit. The server selects an information distribution scheme (unicast or multicast) and sends the information to the subscriber terminal(s). Each subscriber terminal receives the information in accordance with the selected information distribution scheme, and stores the information in the storage unit. The system can cope with multiple requests from the subscribers without increasing the VOD service cost.
