ISO/IEC 14496-1:2010
Information technology — Coding of audio-visual objects — Part 1: Systems
ISO/IEC 14496-1:2010 specifies system level functionalities for the communication of interactive audio-visual scenes, i.e. the coded representation of information related to the management of data streams (synchronization, identification, description and association of stream content).
