Abstract
Abstract In a digital tuner, a tuner subunit 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 transmits the selected data stream to an 1394 serial bus. 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.
