Abstract:
A receiving system and a receiving device are provided for receiving and processing broadcast digital and analog signals such as video and audio programs. The system and device are capable of determining whether a received program is subject to copy prohibition. If the program is subject to copy prohibition, the system prevents copying of the program. The system and device are capable of performing timed recording of received programs, including checking the status of the device and/or the recording medium to determine whether timed recording is permitted. Timed recording may be permitted if a selected broadcast receiving device is a registered device.
