Abstract
When data is transmitted by using a broadcasting channel of an IEEE1394 interface, it is enabled to cope with a case where undefined equipment is connected to an IEEE1394 bus. The IEEE1394 interface is provided for an IRD, thereby enabling the IRD and equipment such as digital VCR, MD player/recorder, or the like to be connected. A node No. “63” of IEEE1394 is set to the broadcasting channel. Data is transmitted to all equipment connected to the IEEE1394 bus by the broadcasting channel. In the broadcasting channel, a picture plane for selecting a transport stream of MPEG and PCM audio data is displayed, and the data which is transmitted by the broadcasting channel can be selected in accordance with the transport stream of MPEG and the PCM audio data. Thus, when undefined equipment is connected to the IEEE1394 bus, it is possible to cope with any equipment.
