Patent ID: 7352813

Claim:
A PVR-support video decoding system comprising: a TS (Transport Stream) decoder for decoding a video PES (Packetized Elementary Stream) from an input TS bitstream to output the decoded video PES; a video decoder for variable-length-decoding the video PES outputted from the TS decoder, and restoring the video PES to pixel values of an original picture through an IQ (Inverse Quantization) process, an IDCT (Inverse Discrete Cosine Transform) process, and an MC (Motion Compensation) process; and a PVR (Personal Video Recorder) engine comprising: a video feature extractor for extracting error correction information, header information and macroblock information from the video PES outputted through the TS decoder, analysis characteristics of a video sequence, and then outputting analyzed information; an index engine for storing the TS bitstream outputted through the TS decoder and the analyzed information extracted by the video feature extractor in a storage medium; and a search engine for searching for and displaying the TS bitstream and the analyzed information stored in the storage medium, wherein the header information identifies a picture coding type and a temporal reference of the TS bitstream.
