Title: Moving picture decoder and method for decoding using the same
Inventor: JUNG YEONG AN
IPC: H04N19/139
Filed: 2002-10-02
Abstract: PURPOSE: A decoding method using an MPEG decoder is provided to compensate for motion vector errors caused by channel errors within video frames when decoding a motion picture bit stream, thereby improving displayed video quality. CONSTITUTION: A buffer temporarily stores a motion picture bit stream compressed in a decoder, and a VLD(Variable Length Decoder) performs an inverse variable length encoding process for the bit stream(S301). If a decoded video frame is in inter-mode, a motion vector is extracted to be decoded(S302). A motion compensator decides whether a motion vector exceeding a decoded video frame range exists(S303). If so, the motion vector is restricted within the decoded video frame range(S305), and the motion compensator executes an MC(Motion Compensation) process for the motion vector(S304). If all motion vectors exist within the video frame, the motion compensator executes the MC process(S304). The motion compensator obtains differences between the motion vector without an error or the restricted motion vector and a previous video frame, and reproduces videos by adding the differences to an inverse-DCT(Discrete Cosine Transform) video frame(S306).
