摘要:
In each embodiment of this invention, when the precondition information of a broadcast program is cut on the viewer side, the use of the broadcast program is limited. A broadcasting system includes a broadcasting apparatus which sequentially transmits first broadcast data containing first control information and second broadcast data containing second control information over the same channel, and a receiving apparatus which executes, upon sequentially loading of the first and second broadcast data, processing based on the first control information and second control information on the basis of an input command. With this arrangement, when first or second broadcast data is precondition information and the precondition information of a broadcast program is cut on the viewer side, since first or second control information is omitted, the use of the broadcast program can be limited.
