Abstract: A video processing system is operable to perform one or more display queue trick (DQT) operations utilizing decoded frames queued in memory. The decoded frames are generated from the start of random access points (RAPs) in frame segments in an encoded video stream. Location of RAPs may be determined during decoding of the encoded video stream. Exemplary encoding scheme comprise MPEG, AVC and/or VC1. The DQT modes include forward and/or reverse display modes. The used frames are selected based on determination of DQT mode parameters, queuing limitations and/or frame properties of selected and/or unselected frames in the frame segments. Frame properties comprise frame discardability and/or display inter-frame dependencies between selected and/or unselected frames. The video processing system is operable to jump to preceding and/or subsequent RAPs during DQT mode operations. The video processing system is also operable to skip one or more RAPs during such jumps.

Abstract: Presented herein are systems, methods, and apparatus for improving performance of video decoders during rewind and fast forward operation. Video decoder performance is improved by avoiding repetitive decoding of prediction pictures. When a decoded prediction picture is stored in a frame buffer, techniques are presented for decoding multiple pictures in the rewind order which are dependent thereon, displaying the picture directly from the frame buffer, and setting one type of prediction picture as another type of prediction picture.

Abstract: Systems, methods, and apparatuses are provided for concealing errors in video data. It is detected whether a slice group in a picture contains errors. When the slice group contains errors and the picture is not a first intra-picture following a channel change, the slice group in the picture is replaced with a slice group of a most recent intra-coded picture. When the slice group contains errors and the picture is the first intra-picture following the channel change, the slice group is replaced with black pixels.
