摘要： Apparatuses and methods for improving coding processes and coding parameters for coding video data are provided for. A coder may select coding parameters for video data according to a default coding policy. The default coding policy may include selection of prediction modes (e.g., intra-coding or inter-coding) for each pixel group in each frame. A video coder may select some pixel groups in a frame to be coded as refresh pixel groups as an exception to the default assignment policies. The selection of refresh pixel groups may be based on prediction relationships among multiple frames of source video data. The default coding of the refresh pixel groups is then modified to enhanced the coding of the refresh pixel groups. The refresh pixel groups may permit fewer intra (I) frames be sent and/or may improve the quality of the recovered video.

摘要： A video decoder system includes a video decoding engine, noise database, artifact estimator and post-processing unit. The video coder may generate recovered video from a data stream of coded video data, which may have visually-perceptible artifacts introduced as a byproduct of compression. The noise database may store a plurality of previously developed noise patches. The artifact estimator may estimate the location of coding artifacts present in the recovered video and select noise patches from the database to mask the artifacts and the post-processing unit may integrate the selected noise patches into the recovered video. In this manner, the video decoder may generate post-processed noise which may mask artifacts that otherwise would be generated by a video coding process.
