Abstract:
1. A broadcasting system comprising: a broadcasting apparatus which sequentially transmits commercial data containing first control information and commercial ID, and program data containing second control information and commercial ID over the same channel; and a receiving apparatus which executes, upon sequential loading of the commercial data and the program data, processing based on the first control information and second control information on the basis of an input command; wherein the receiving apparatus includes: a receiving device configured to receive the commercial data and program data transmitted from the broadcasting apparatus; a first extracting device configured to extract the commercial ID and the first control information from the commercial data received by the receiving device and holding the commercial ID and the first control information: a second extracting device configured to extract the commercial ID and the second information from the program data received by the receiving device and holding the commercial ID and the second information while sending out the commercial ID; a comparing device configured to compare the commercial ID received from the second extracting device with the commercial ID held in the first extracting device and determining whether they coincide with each other; sending out a first determination output signal when the determination result indicates that they do not coincide with each other or the first extracting device holds no commercial ID; and sending out a second determination output signal when the determination result indicates that they coincide with each other; a permission device configured to permit, upon reception of the second determination output signal, recording/playback control operations and services set for the respective program data on the basis of the first and second control information held in the respective extracting device; and a limiting device configured to limit, upon reception of the first determination output signal, recording/playback of the digital broadcast and services on the basis of the second control information held in the second extracting device; wherein the first control information contains program recording control information, playback control information after recording, and participation right control information in the case of a viewer participation program; and the second control information contains information used for program viewing/recording control while no commercial data is received and the first control information.
