摘要： Apparatus and methods are provided for recording and reproducing digital image data. In a reproducing apparatus, two tracks of digital image data are simultaneously reproduced in a high definition mode of operation, while in a standard definition mode of operation only a single track of data is reproduced at a given time. In the high definition mode of operation, the data reproduced from the two tracks simultaneously are time-division multiplexed and supplied in multiplexed form to a digital interface for transmission to another apparatus, such as a recording apparatus for dubbing. In a recording apparatus, operating in a high definition mode digital image data is recorded simultaneously in two tracks on tape. In one embodiment, the data to be recorded is also multiplexed time-divisionally and supplied to a digital interface for transmission, but in a standard definition mode, the data is not multiplexed prior to transmission. In other embodiments, a recording apparatus is supplied with communication circuits for demultiplexing high definition image data received from a transmission line for simultaneously recording first and second portions of the image data in respective tracks on a tape.

摘要： Picture data received in the order of DC components and AC components is stored in a frame memory 115. At this point, an ID number detecting portion 117 detects an ID of a sync block and sends the detected ID to an encoding portion 114. Corresponding to the ID, the encoding portion 114 determines whether or not data that is read from a frame memory 93 is a buffering unit that has been stored. Thus, when the read data is the buffering unit, the read data is output as it is. When the read data is not the buffering unit, gray data is output.

摘要： A method of dubbing compressed digital video signals adopted for an apparatus for efficient coding and subsequent recording/playback of video signals. In the method of dubbing compressed digital video signals, on a playback unit side, after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit of playback, the digital video signal is provided with a parity for transmission by a parity generating circuit and is then transmitted to a recording unit side. On the other hand, on the recording unit side, after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit of transmission, the digital video signal is provided with a parity for recording by a parity generator and is then recorded in a recording medium.
