    摘要: The CGMS unacceptable recorder accepts transmission frames only when the copyright protection information in a transmission header transmitted to the IEEE1394 serial bus indicates copy free. The CGMS acceptable recorder accepts transmission frames when the copyright protection information in the transmission header indicates copy free. When the copyright protection information in the transmission header indicates compliance with the copyright information contained in the content of the transmission frame, the copyright information in the content is fetched based on the signal format type information of the transmission header. As described herein above, a copy management information changeable apparatus such as a computer cannot accept data other than copy free signals from the digital interface.

    摘要: A communications system connected via a bus capable of transmitting multiplexed packets of control signals and AV signals while providing an environment, which is the same as an environment where connections are made using analog signal lines. A register with a fixed address is taken to be a virtual plug for each of a plurality of equipment. When the plug enable for the input plug is set to 1, an isochronous communication packet for the AV signal on the channel set by the channel number is received. When the plug enable for the output plug is set to one and the isochronous communication packet for the information signal is sent on the channel, then the channel number is set in the channel number field at a transmission speed designated by the DR (Data Rate) field at the bandwidth presented in the bandwidth field.

    摘要: A bus connects a plurality of electronic devices. The address of a prescribed electronic device having a single connection-terminal is assigned based on parent/child considerations. The prescribed device having a single connection terminal is controlled by a designated device so that other devices on the bus cannot directly communicate with the prescribed device other than through the designated device. In one embodiment, the bus is a P1394 audio/visual serial bus, the prescribed device is a camcorder, and the designated device is a VCR.
