Data processing apparatus and data transmission method

摘要

In an arrangement intended to make it possible to deal with an electronic apparatus as if it were a different kind of electronic apparatus, an editor (1) outputs a command to be used in controlling a video cassette recorder (3) to a 1394 communication section (31) via an IEEE 1394 bus (11). A system controller (54) receives the command according to the IEEE 1394 interface via a LINK (52) and converts it into a command according to the IDE interface, which is output to an IDE controller (71). The IDE controller (71) converts data that is input via the LINK (52) and a FIFO memory (61) into a command according to the IDE interface and supplies it to a HDD (4) via an IDE interface (12).
