Introduction and Scope

ITU-T Recommendation H.263 (01/05) [4] has been adopted as a video codec for various 3GPP2 multimedia services such as Multimedia Messaging Service (MMS, [1]), Multimedia Streaming Service (MSS, [2]), and Packet Switched Video Telephony (PSVT, [3]). The ITU-T recommendation [4] only specifies syntax elements and decoding process under lossless condition. However, parts of video information for 3GPP2 Packet Switched Multimedia (PSM) Services may be lost due to latency, over the air loss, etc. Therefore, this specification provides informative recommendation of H.263 decoding when parts of video information for 3GPP2 PSM services are lost.
