Abstract
Abstract In a digital tuner (1) a tuner subunit (11) selects a data stream of one or more programs from a data stream in which digital signals of a plurality of programs are multiplexed, and a 1394 interface (13) transmits the selected data stream to a 1394 serial bus (3). A logical output plug is set in the tuner subunit, and the data stream of the one or more programs is output to the 1394 interface from the output plug.
