摘要： A system, method, and apparatus for reducing the video decoder processing requirements for rewinding a HITS stream are presented herein. During rewind of a HITS stream, the video decoder builds a clean reference picture. The clean reference picture is built by decoding each of the P-pictures in the EP-EP segment. However, because the P-pictures are not displayed, the decoder does not decode the portion of the P-picture below the last intracoded slice. The decoder can build the clean reference picture without decoding the portions of the P-pictures below the last intracoded slice because the subsequent pictures do not use the said portions for prediction.

摘要： A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.

摘要： 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.

摘要： Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data.

摘要： A system, method, and apparatus for providing display parameters from the decode process to the display process are presented herein. The decode process receives images which are encoded according to a predetermined standard. Included with the encoded images are parameters which facilitate the decode and display processes. The decode process decodes the encoded images as well as the parameters and stores each image in a separate image buffer. Additionally, the decode process stores the parameters which facilitate the display process in a buffer descriptor structure associated with the image buffer. The display process uses the parameters stored in the buffer descriptor structure during the display process.
