Wireless MPEG ‐4 Videocommunications*
Madhukar Budagavi · 2003
Abstract In this article we provide an overview of wireless videocommunications and described the various international standards that have made it possible. We describe the Simple Profile of MPEG‐4 video compression standard which in addition to specifying the video compression scheme, also introduces several error resilience tools aimed at containing the effect of transmission errors in the video bit stream. In practice, video is usually transmitted along with speech, audio, multimedia data such as images and documents, and control signals to form a complete multimedia communication system. Hence we also provide an overview of the following multimedia communication systems standards that have been recommended by Third Generation Partnership Project (3GPP) for use over third generation wireless networks: 1. Multimedia Messaging Services (MMS) for multimedia messaging, 2. Real‐time Streaming Protocol (RTSP) for streaming, 3. Session Initiation Protocol (SIP) for videoconferencing over packet‐switched wireless networks, and 4. 3G.324 for videoconferencing over circuit‐switched wireless networks.
