NETWORK, TRANSMITTER TERMINAL AND METHOD OF FORMING ACCESS POINT IN DATA STREAM

摘要

PURPOSE: A network, transmitter terminal and the method of forming access point in data stream are provided to avoid to code a new scene description every time an access point is to be inserted into the stream. CONSTITUTION: A telecommunications network comprises a transmitter terminal including a multi-media scene description coder for producing a data stream which contains access points formed by coded data relating to a complete scene description, and a receiver terminal which is connected at any instant to the transmitter terminal for receiving the data stream. The transmitter terminal includes a storage memory for storing data coded at a given instant and relating to a description of a complete scene, wherein the stored data is intended to be used at one or several later instants to form the access points.
