    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.

    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. An encoder device determines one or more distortion values for one or more portions of multimedia data based at least in part on one or more concealment methods related to concealing the one or more portions if the one or more portions were received in error. The encoder device determines one or more encoding methods for the one or more portions based at least in part on the one or more estimated distortion values. In one aspect, determining the one or more encoding methods comprises determining the one or more encoding methods so as to refresh the one or more portions based at least in part on a comparison of the one or more estimated distortion values and one or more thresholds.
