Abstract
Receiver_id[k] (each 16 bits) indicating the ID of a receiver for carrying out reception control and control_status[k] indicating whether reception of digital broadcast signals for redistribution by the receiver having the ID indicated by receiver_id[k] is allowed are set in private_data (680 bits) which is secured beforehand in a TSMF packet as an area which an enterprise for supplying digital broadcast signals for redistribution can arbitrarily use. In a reception device, the reception of digital broadcast signals is controlled on the basis of control_status corresponding to the ID thereof.
Claims14
A transmission device, comprising:
- a receiving unit operable to receive a digital broadcast signal distributed from a prescribed distribution device;
- a first generating unit operable to set identification information corresponding to a reception device and reception control information for controlling the reception operation of the reception device in an area secured in advance in a format of composite information, thereby generating composite information;
- a second generating unit operable to compose a predetermined number of digital broadcast signals on the basis of the composite information to generate redistribution digital broadcast signals containing the composite information;
- and
- a transmitter operable to transmit the redistribution digital broadcast signals to the reception device.
A transmission method, comprising:
- receiving a digital broadcast signal distributed from a prescribed distribution device;
- setting identification information corresponding to a reception device and reception control information for controlling the reception operation of the reception device in an area secured in advance in a format of composite information, thereby generating composite information;
- composing a predetermined number of digital broadcast signals on the basis of the composite information to generate redistribution digital broadcast signals containing the composite information;
- and
- transmitting the redistribution digital broadcast signals to the reception device.
