<p>Copy generation management information is detected by a copy flag detecting circuit of an apparatus. The copy generation management information is inserted into the CIP header of an IEEE 1394 packet and transmitted. The copy generation management information in the CIP header is detected by a copy flag detector of a 13941/F of the apparatus. In accordance with the detection result, a copy generation management circuit records the new copy generation management information and a record control circuit permits or forbids the recording. With this constitution, a decoding circuit on a receiver side can be eliminated.</p> |
