ABSTRACT:
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.
