摘要： Noise is prevented when decoding an audio stream not containing syncwords or CRC bits in the elementary stream. When decoding a current frame, the private header of the next frame is analyzed and the current frame is muted if the private header of the next frame is not valid. When there is a data discontinuity caused by editing, decoding resumes from the start address of the next frame determined.

摘要： Color difference signals of demodulated video are vertically filtered to be converted into 4:2:2 signals before subjected to OSD synthesis, after which those signals are once again vertically filtered as a sort of scaling to obtain the output resolution. As filtering is carried out in two stages, the frequency characteristic deteriorates. A video processor superimposes an OSD video signal on a 4:2:0 format video signal, and includes: a converting section for converting the OSD video signal into YUV signals; an OSD luminance signal scaling section for performing scaling on an OSD luminance signal included in the YUV signals; a luminance signal synthesizing section for synthesizing the scaled OSD luminance signal and the luminance signal of the 4:2:0 format video signal; an OSD color difference signal scaling section for performing scaling on OSD color difference signals included in the YUV signals; and a color difference signal synthesizing section for synthesizing the scaled OSD color difference signals and the color difference components of the 4:2:0 format video signal.

摘要： A video scan converter processes a video stream including a first coding unit, which has been obtained by encoding a pair of fields N1 and N2 that has come from a first frame of film video, and a second coding unit, which has been obtained by encoding a pair of a field N3 that has also come from the first frame and a field M1 that has come from a second frame, not the first frame. The video scan converter includes: a decoder, which receives the video stream, decodes the first and second coding units, and sequentially outputs the data of the respective fields N1, N2, N3 and M1; and a scan converter, which generates a frame based on associated two of those fields that have been supplied from the decoder. In outputting a frame associated with the field N3, the scan converter generates the frame based on the fields N1 and N2 without using the data of the field N3.
