Next, the operation of the conventional digital broadcast receiving apparatus will be described. First, the number of the channel of the program to be displayed is input to the program selection means 109, and this information is output to the demultiplexing means 102. In the demultiplexing means 102,
The channel input to the program selecting means 109 is selected. One transponder usually includes programs of 4 to 6 channels.
If the transponder received from 1 does not include the channel, the channel decoding unit 101 selects one transponder including the channel from the output signals of the plurality of transponders received.
The above-mentioned channel is selected and extracted from a plurality of channels included in the output signal of the transponder, output to the source decoding means 103, and EPG information is extracted from the transponder to obtain a program table generating means 108

The program information and the video signal and the audio signal reproduced by the source decoding means 103 are synthesized by the information synthesizing means 105 and displayed on a display means 106 on a screen. When recording the program of the channel being displayed on the display unit 106, the video signal and the audio signal output by the source decoding unit 103 are output to the recording unit 107, and the recording unit 107 records the received signal.

FIG. 6 is a diagram showing another example of a conventional digital broadcast receiving apparatus for receiving a digital broadcast and outputting and displaying a reproduced signal thereof. 5, the same reference numerals as those in FIG. 5 denote the same or corresponding parts.

Reference numeral 113 denotes recording-side source decoding means, which decodes and outputs an encoded signal of the channel selected by the recording-side demultiplexing means 112.

Next, the operation of the digital broadcast receiving apparatus will be described. When recording the same program as the program to be displayed, or when recording a program on a channel different from the channel being displayed on the display means 106, the STB is output in exactly the same manner as in FIG. The desired program is displayed on the display means 106, and the recording-side channel decoding means 111 selects and outputs one transponder including the channel to be recorded among the plurality of received transponders, and outputs a plurality of transponders included in the transponder. The recording-side demultiplexing means 112 selects and extracts a desired channel from the channels, and outputs this to the recording-side source decoding means 113. The signal output from the recording side source decoding means 113 is recorded by the recording means 107.

In the conventional digital broadcast receiving apparatus shown in FIG. 5, the signal output from the demultiplexing means 102 is recorded in the recording means 107 as described above. Demultiplexing means 10
Only the program of one channel selected in 2, that is, the program being displayed can be recorded, and the program of a channel different from the channel of the program being displayed cannot be recorded. On the other hand, in another conventional digital broadcast receiving apparatus shown in FIG.
And a second STB is provided separately from the second STB.
Since the recording-side channel decoding means 111, the recording-side demultiplexing means 112, and the recording-side source decoding means 113 are provided in the TB, even if the program is being displayed on the display means 106, the program being displayed is displayed. Can be recorded on a channel other than the channel.

[0007]

The conventional digital broadcast receiving apparatus is configured as described above and cannot record a program on a channel other than the channel of the program being displayed. By having the means and the like, it is possible to record a program on a channel different from the program being displayed.

[0008] In the latter, EPG (Electronic Program Guide) information about the program being displayed that is acquired is:
Since the demultiplexing means 102 extracts the signal from the transponder selected by the channel decoding means 101, the EPG information includes channel numbers for programs of 4 to 6 channels included in the transponder,
Program information such as a channel name, a program name, and a schedule is described. Therefore, when recording a channel included in the same transponder as the transponder other than the channel of the program being displayed, recording using the program information may be considered. However, since the EPG information also describes information that one of these channels is being displayed, program display can be selected using the EPG information. Cannot be done.

[0009] Therefore, it is possible to select program recording by using the original EPG information on the recording side, but the EPG information is used only for the E-channel related to the currently displayed channel.
Since it is independent from the PG information, it is necessary to separately select program display and program recording using separate program guides created from these two pieces of EPG information. Therefore, when recording the channel included in the transponder including the channel being displayed,
Despite two EPG information being basically the same,
Since it is not possible to select a program to be displayed and a program to be recorded on the same program table while comparing them, the program table becomes cumbersome, and the advantage of the program table that the program can be selected at a glance is spoiled.
