摘要： A method of recording video data and the accompanied sound data capable of editing the video data and sound data track by track without editing gaps is disclosed. The track format includes a first block of tracks for video data and a second block of tracks for sound data for a predetermined number of frames. Another method of selectively recording one of a plurality of kinds of video data having different amounts of data per frame or field and the accompanied sound data (NTSC and PAL for example) is provided. In this method, the video data and sound data are recorded with a recording and editing unit which is a determined by a common multiple of the selected one of kinds of video data among the amounts of data of the different kinds of video data. In NTSC method the video and sound data are receded every six frames or fields and in the PAL method, the video and sound data are recorded every 5 frames or fields, so that a track pattern having T=24 tracks including P tracks for sound data and T-P tracks for video data are recurrently recorded. The video and sound data are recorded track by track, so that video and sound data can be edited tack by track.

摘要： A method for recording and reproducing digital signals in and from a recording medium is provided. The digital signals are to be recorded in any given k-th mode of N-kind digital signal transmission modes of mutually different packet sizes. Digital signals of p.sub.k packets with additional data are recorded on tracks of the recording medium in unit of d.sub.k data blocks. Data blocks of a multiple of the least common multiple R of the data block recording units of the respective digital signals of the N-kind digital signal transmission modes are recorded in each track. The data blocks recorded in the recording medium are reproduced. Here, N is a two or more natural number, k is 1 to N, and p.sub.k and d.sub.k are a natural number. There is a case where the digital signals are to be recorded in first and second digital signal transmission modes of two different packet sizes. In this case, in the first digital signal transmission mode, the digital signals of one packet in unit of two data blocks with the additional data are recorded. Further, in the second digital signal transmission mode, the digital signals of two packets in unit of three data blocks with the additional data are recorded. And, the data blocks of a multiple of six are recorded in each track on the recording medium.

摘要： In a recording and reproducing apparatus, time stamps are generated which represent moments of arrival of sequentially-inputted packets of data respectively. The generated time stamps are added to the sequentially-inputted packets respectively, and thereby the sequentially-inputted packets are converted into second packets respectively. The second packets are recorded on a recording medium. The second packets are sequentially reproduced from the recording medium. The time stamps in the respective reproduced second packets are detected. A detection is made as to whether each of the detected time stamps is correct or wrong. When a wrong time stamp is detected, a reproduced second packet is discarded which relates to the detected wrong time stamp.

摘要： Audio packets are separated from an input stream of packets including audio packets and video packets. The audio packets relate to audio information. The video packets relate to video information. The video packets are separated from the input stream of packets. The separated audio packets are recorded on first tracks among an array of tracks on a recording medium. The first tracks are spaced by equal intervals corresponding to a given number of tracks. The separated video packets are recorded on second tracks among the array of tracks on the recording medium. The second tracks differ from the first tracks. The first tracks are scanned, and the audio packets are reproduced from the first tracks during high-speed playback. An output stream of packets is generated in response to the reproduced audio packets during the high-speed playback.

摘要： Input picture information is divided into first and second division-resultant signals. Y-signal DCT blocks, Cr-signal DCT blocks, and Cb-signal DCT blocks are generated from the first division-resultant signal. Y-signal DCT blocks, Cr-signal DCT blocks, and Cb-signal DCT blocks are generated from the second division-resultant signal. Dummy DCT blocks are generated which are distinguishable from the Y-signal DCT blocks related to the first and second division-resultant signals. The Y-signal DCT blocks, the Cr-signal DCT blocks, and the Cb-signal DCT blocks related to the first division-resultant signal, and the dummy DCT blocks are grouped into macro-blocks each having two Y-signal DCT blocks, one Cr-signal DCT block, one Cb-signal DCT block, and two dummy DCT blocks to modify the first-division-resultant signal into a first modification-resultant signal. The Y-signal DCT blocks, the Cr-signal DCT blocks, and the Cb-signal DCT blocks related to the second division-resultant signal, and the dummy DCT blocks are grouped into macro-blocks each having two Y-signal DCT blocks, one Cr-signal DCT block, one Cb-signal DCT block, and two dummy DCT blocks to modify the second division-resultant signal into a second modification-resultant signal. The first modification-resultant signal is compressed by DCT and variable length encoding while a data amount of the first compression-resultant signal per given number of macro-blocks is maintained at a fixed amount. The second modification-resultant signal is similarly compressed.
