ABSTRACT:
In a data transmitting/reproducing equipment, e.g., a digital audio tape-recorder, etc., adapted for transmitting data on an information transmission line such as a magnetic tape, etc. where a plurality of formats exist, and reproducing that data through the information transmission line, a scheme is adopted in this invention to guarantee an upgradable format having compatibility in which there are not only so called an upper compatibility but also a lower compatibility with respect to apparatuses already existing. To realize this scheme, on the transmitting or recording side, format ID information indicating a format of transmit data, and a plurality of compatibility ID information indicating compatibility of that format relative to other formats are generated and added to the transmit data, thus to transmit the transmit data on the information transmission line along with the format ID information and the compatibility ID information added thereto. On the receiving or reproducing side, transmit data transmitted through the information transmission line from the transmitting side is reproduced in accordance with the compatibility ID information.
