An MPEG-4 video codec (MoVa) has been developed for implementation of video coding applications according to 3G-324M. On 3G-324M, H.263 is mandatory and MPEG-4 is optional. However, MPEG-4 is proper for mobile multimedia applications (IMT-2000) by its error resilient and concealment tools. It can perform 30 frames/s of QCIF (SQCIF) or 15 frames/s of CIF at a maximum clock rate of 27 MHz for 128 kbps or 144 kbps. It meets the requirements for MPEG-4 SP@L2. A high bit rate and several sizes of video format are adequate for many applications, like videoconferencing, surveillance, news, or entertainment.
