Abstract
MPEG-4 is to standardize interactive multimedia applications, including image manipulation, storage and transmission, for bit rates up to 4 Mbit/sec. Interactive graphical applications of MPEG-2 are mentioned and the possibility of downloading decoder tools is stated. Requirements for MPEG-4 are listed, ranging up to dynamic resource management. Low delay and main profiles are contrasted and the MPEG-4 system level is described, to allow synchronisation of individual AV objects. MPEG-4 audio facilities are also considered. Synthetic natural hybrid encoding (SDNHC) is explained. Contents related to video encoding and video verification are explained. Video compression is similar to MPEG-2.
