DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIG. 1 and FIG. 2, but here, an in-vehicle type capable of viewing terrestrial digital broadcasting is illustrated. FIG. 1 is a block diagram showing a digital broadcast receiver, and FIG. 2 is a flowchart showing viewer residence area information setting processing.
[0012]
In FIG. 1, an antenna 1 receives a digital broadcast signal transmitted from a terrestrial broadcast station. The tuner 2 extracts a signal of a specific frequency from the high frequency digital modulation signal including video / audio data. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.
[0013]
The demultiplexer (DEMUX) 3 separates the transport stream into an MPEG2 (Moving Picture Experts Group 2) video stream, an audio stream, and PSI / SI (Program Specific Information / Service Information). The demultiplexer 3 supplies the video stream and the audio stream to the AV decoder 4 and supplies program information (program name, program start time, program duration, etc.) included in the PSI / SI to the CPU 13. Note that a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from among these is the packet ID of the arbitrary channel in the transport stream from the PSI / SI. It becomes possible by taking out data such as whether or not it is multiplexed. The transport stream can also be selected based on PSI / SI information.
[0014]
The AV decoder 4 includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. The video decoder decodes the input variable length code to obtain a quantization coefficient and a motion vector, and performs inverse DCT conversion, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input encoded signal to generate audio data. The video data generated by the decoding is output to the video processing circuit 5, and the audio data is output to the audio processing circuit 6.
[0015]
The video processing circuit 5 receives video data from the AV decoder 4, performs D / A conversion to generate a video signal, and supplies this to the display 17. The audio processing circuit 6 receives the audio data output from the AV decoder 4 and performs D / A conversion to generate, for example, a right (R) sound analog signal and a left (L) sound analog signal, which are output to a speaker. 16 is supplied.
