<p>PROBLEM TO BE SOLVED: To provide a digital data transmitter-receiver that allows a receiver to continuously receive digital data even when stopping of the AV data is unavoidable because of production of AV data whose channel number information is in duplicate. SOLUTION: The digital data transmitter-receiver is provided with a synchronous data transmission means 1, a channel information management processing means 3, a channel number revision notice means and a channel number information revision recognition means 4c. When re-acquisition of a channel is failed after the occurrence of bus reset, other non-use channel number is retrieved and when the non-use channel is detected, the transmitter-receiver informs other device about revision of the channel number information and restarts transmission of AV data with a newly detected channel number.</p> |
