Abstract:
An AV communication control circuit suitable for a radio LAN-LSI in a radio AV transmission/reception device is formed by a copyright protection processing unit configured to carry out a copyright protection processing with respect to AV data entered from an AV stream signal line, a selection unit configured to select either one of AV data entered from an AV stream signal line through the copyright protection processing unit and AV data entered from a general purpose bus, and a transmission control unit configured to carry out control for transmitting AV data selected by the selection unit to a network.
