    摘要： A wireless communications device configured to operate in a multimedia broadcast system is disclosed. The wireless communications device includes a receiver configured to receive a plurality of video streams each comprising intra-coded and inter-coded video frames. The wireless communications device also includes a video decoder, and a processing unit configured to switch the video streams to the video decoder. The processing unit is further configured to receive a prompt to switch from a first one of the video streams to a second one of the video streams, and in response to the prompt, delay switching to the second one of the video streams until an intra-coded video frame is received in the second one of the video streams.

    摘要： Methods and apparatuses to encode multimedia data enabling, among others, for example, improved decoded video quality, improved error recovery capabilities and/or improved decoding efficiency are described. A method according to the application includes one or more of the following: initializing a pixel-level reference counter for a current frame, performing a prediction of a next frame referring to the current frame, incrementing the pixel-level reference counter for each pixel of the current frame that is referenced during the prediction of the next frame, readjusting a macroblock bandwidth map of the current frame, repeating the steps of initializing, performing and readjusting for each next frame in a plurality of next frames referring to the current frame, and encoding the current frame based at least in part on the readjusted macroblock bandwidth map of the current frame.
