    摘要: Conversion of audio data is performed such that a bit stream conforming to the DVD-VR standard is converted into a bit stream conforming to the DVD-video standard.A stream converter includes: a first converter for receiving a bit stream conforming to a DVD-VR standard, converting data except for audio data in the bit stream into data conforming to a DVD-video standard, and outputting a resultant bit stream; and a second converter for converting, when the audio data in the bit stream output from the first converter does not conform to the DVD-video standard, the audio data into data conforming to the DVD-video standard, and outputting a resultant bit stream.

    摘要: A reproducing device has an input means for inputting an MPEG transport stream from a hard disk; and reproducing means for reproducing the inputted MPEG transport stream, in case of reproducing a special reproduction image, the input means extracts an MPEG transport stream from an arbitrary position to another arbitrary position in the inputted MPEG transport stream to output the special reproduction image used for special reproduction, and the reproducing means reproduces the special reproduction image while detecting whether a plurality of pieces of picture data exist in one of MPEG transport packets constituting the outputted special reproduction image.

    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.
