Broadcasting receiving apparatus and broadcasting receiving method
First Claim
1. A digital-broadcasting receiving apparatus comprising:
- a scanning member to scan broadcast data of each of a plurality of sub-channels included in each of a plurality of physical channels transmitted by a digital-broadcasting wave, the broadcast data being coded with an MPEG2-TS methoda decode judgment member to judge whether broadcast data of a sub-channel is scrambled data or not by judging whether the broadcast data can be decoded or not;
a first registration member to register the sub-channel as a viewable channel when a first judgment result obtained by the decode judgment member is that the broadcast data of the sub-channel is not scrambled data;
a scramble judgment member to judge whether the broadcast data of the sub-channel is scrambled data or not by referring to one of a transport scrambling control bit in a header region of video data of the sub-channel, a descriptor tag in the program map table included in the video data or audio data of the sub-channel, and a packetized elementary stream scrambling control included in the video data or the audio data of the sub-channel;
a second registration member to register the sub-channel as a viewable channel when a second judgment result obtained by the scramble judgment member is that the broadcast data of the sub-channel is not scrambled data;
a judgment member to judge whether the first judgment result accords with the second judgment result or not for the sub-channel; and
a channel registration control member to allow the first registration member to register the sub-channel when the judgment member judges that the first judgment result does not accord with the second judgment result, and to allow the second registration member to register the sub-channel when the judgment member judges that the first judgment result accords with the second judgment result.
