    摘要: The time necessary for dubbing of a bit stream is reduced.A high speed dubbing apparatus includes: a read section (20) for reading a bit stream conforming to a DVD-VR standard from a first storage device (10), and outputting the bit stream; a first buffer (30) for storing an output from the read section (20) and outputting a bit stream; a navigation pack generator (40) for replacing a real time data information pack in the bit stream output from the first buffer (30) with a navigation pack, and outputting a resultant bit stream; a second buffer (50) for storing an output from the navigation pack generator (40) and outputting a bit stream; and a write section (60) for converting the bit stream output from the second buffer (50) into a bit stream conforming to a DVD-video standard, and writing the resultant bit stream in a second storage device (70). At least two of the read section (20), the navigation pack generator (40) and the write section (60) operate in parallel.

    摘要: An image reproduction apparatus that selects arbitrary video/audio data among a plurality of MPEG transport streams which have been recorded in a storage medium at different times, and re-multiplexes the selected video and audio data into one MPEG transport stream to be reproduced. When a MPEG transport stream is recorded in the storage medium, a reference clock is generated from Program_clock_reference in the stream, and then the MPEG transport stream is recorded with the generated reference clock attached thereto as an Arrived Time Stamp. At the start of reproduction, a common PCR is generated on the basis of the ATS value to be used as a video/audio PCR. Further, as for PTS and DTS, the difference value in the ATS of packets having PTS and DTS in the same video/audio is calculated, and the video or audio is outputted so as not to vary the difference value.

    摘要: In jumping reproduction, when an MPEG transport stream processed by the jumping reproduction is decoded and displayed, many noises occur in the video and the audio corresponding to the vicinity of the jumping.Provided are: a hard disk section 208 of reading and reproducing AV data recorded as an MPEG transport stream in a recording medium; and an AV transfer control block 211 of controlling the hard disk section 208 in such a manner that during the reproduction of the AV data, when the reproduction is performed with skipping a predetermined portion of the AV data, before the skipping of the predetermined portion, transport packets are outputted up to the last one among those constituting a frame, and that after the skipping of the predetermined portion, transport packets are outputted starting from the beginning transport packet of the next I frame.
