Just think of multimedia. This paper describes how the MPEG-4 standard, with its application-level features and its network-awareness but independence is poised to become the enabling technology for multimedia communications and will therefore contribute to solve the problems that are hindering Multimedia Communications. Contained in this header is the information necessary to restart the decoding process and includes: The CATV industry is following. The computer industry takes an attitude very similar to consumer electronics', but considerably more articulated. The MPEG-4 standard provides a set of technologies to support the coded representation of units of aural, visual or audiovisual content, called "audio-visual objects" or AVOs; the way individual AVOs are composed in a scene; the way AVOs are multiplexed and synchronised, so that they can be transported over network channels providing a QoS appropriate for the nature of the specific AVOs or the user requirements; a generic interface between the application and the transport mechanisms; the way the user interacts with the scene e. A TV program can be made up of one or more video stream just think of a new program with an inset which is the face of the announcer and one or more audio stream audio channel 1 is English, audio channel 2 is French .
