Abstract

Abstract In a data transmitting/reproducing equipment, e.g., a digital audio tape-recorder, etc., adapted for transmitting data for which a plurality of formats exist, and reproducing that data through the information transmission line, a system is adopted which has not only upward compatibility but also downward compatibility with respect to apparatuses already existing. 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 to add the format ID information and the compatibility ID information to the transmit data. On the receiving or reproducing side, transmit data transmitted through the information transmission line from the transmitting side is reproduced in accordance with one of the plurality of compatibility ID information.
