    摘要: Provided is a digital video recording system which can properly maintain a corresponding relationship between recorded data in two different kinds of formats which are generated from the same inputted video-audio data, even if those data are managed separately. In a case where the first file is generated as a main material file with a high resolution, and the second file is generated as a low-bitrate audio-video (AV) data file (204) with a low resolution, a CLIP-UMID (309) which is identification information unique to the first file is stored in a skip box (304) in the low-bitrate AV data file (204).

    摘要: In a video signal digital magnetic recording and/or reproducing apparatus, an input image data array is rearranged into a different data array appropriate for data compression and then subjected to a data compression by variable length coding. The resulting data are rearranged after the data compression and then recorded sequentially onto a video track of a magnetic tape in the same order as that in the frame. In a high-speed playback mode, only the lower frequency component data is decoded every sync block, so that the data reproduced from one video track adjoin each other in the playback picture on the screen.

    摘要: A signal processing apparatus for use in a digital video signal reproducing apparatus for reproducing digital signal presented in sync blocks is disclosed. Each sync block has a fixed area for low frequency data and five subsequent sync blocks define a sharing group for sharing high frequency data. The signal processing apparatus includes an inner and outer correction circuit for correcting errors in the sync blocks. An error flag is provided to a sync block which still has an error remaining after the processing in the correction circuit. A memory is provided for storing errorless sync blocks of one frame. A substitution switch is provided for passing the errorless sync blocks, but substituting a sync block stored in the memory for a sync block still having some errors. Five sync blocks produced from the substitution switch are held in a delay. When no substitute sync block is detected in the five sync blocks in the delay, the data in the five sync blocks are decoded by a bit rate reduction decoder. But, when one to four substitute sync block is detected in the five sync blocks in the delay, only the low frequency data of the five sync blocks in the fixed area are decoded by the bit rate reduction decoder.
