The ISO/IEC International Standard (IS 14496) for multimedia applications. MPEG-4 is a low bit-rate standard for encoding and compression intended for application in broadcast television, videophones, and mobile phones and other small handheld devices. MPEG-4 is designed for IMT2000 wireless applications at rates of up to 384 kbps upstream and 2 Mbps downstream. MPEG-4 deals with the coded representation of audiovisual objects, both natural and synthetic, and their multiplexing and demultiplexing for transmission, playback, and storage.
