摘要: Using wireless packet loss data in the encoding of video data. In one embodiment, the method includes receiving wireless packet loss data at a wireless transmit receive unit (WTRU); generating video packet loss data from the wireless packet loss data, and providing the video packet loss data to a video encoder application running on the WTRU for use in encoding video data. The video encoder may perform an error propagation reduction process in response to the video packet loss data. The error propagation reduction process includes one or more of generating an instantaneous Decode Refresh frame or generating an Intra Refresh frame. Some embodiments may be characterized as using a reference picture selection method, or a reference set of pictures selection method.
