Description

  The present invention relates to a digital broadcast receiver that receives a digital broadcast, and more particularly to a digital broadcast receiver having a program information presentation function.

  In digital broadcasting, a plurality of channels can be multiplexed and transmitted in one channel bandwidth in conventional analog broadcasting. This makes it possible to broadcast one broadcast at the same time in the allocated frequency band, or to broadcast a plurality of programs by dividing the band into a plurality of bands.

  For example, in BS digital broadcasting, operations such as broadcasting high-definition television broadcasting in a band allocated to a broadcasting station, broadcasting about three channels of standard television broadcasting in the same band, and the like are performed. In digital broadcasting, the allocated bandwidth is divided into 13 segments, 12 of which are used for broadcasting to fixed reception devices, and another channel is broadcasted using the remaining one segment.

Furthermore, in digital broadcasting, the user can perform program search, selection, etc. on a monitor by multiplexing and transmitting digital signals such as program identification information and program arrangement information together with video signals and audio signals of the broadcast program itself. A function called an electronic program guide can be provided. FIG. 4 shows a program table in which the time zone is in the vertical direction and the channel is in the horizontal direction. In the conventional program guide, as shown in FIG. 4, a display area is configured by setting a section for each channel assigned to each broadcasting station. For this reason, the area on the monitor for displaying the program information of each broadcasting station is displayed differently depending on the number of assigned channels. In the program guide, when the same program is broadcast on each channel in the same time zone, the program is displayed for each channel. In this case, it cannot be said that the visibility is necessarily excellent, and further, it cannot be said that the limited display area on the monitor is effectively used. As a technique for solving such an inconvenience, when a same station or a program of the same genre is broadcast in each channel at a broadcasting station to which a plurality of channels are allocated, the program is displayed for each channel. Instead, a technique is disclosed in which channels having the same program are integrated into one broadcast channel and displayed (for example, described in Patent Document 1).
JP 2004-135166 A

  However, this technique is effective when the same program exists over a plurality of channels in the same time zone, and when displaying the case where the program table displayed on the monitor does not broadcast the same program in the same time zone, Each program information will be displayed in every division. As a result, the amount of broadcast station information displayed is reduced by the amount of program information presented for each channel, and the listability is not excellent for users accustomed to program schedules published in printed materials such as newspapers and magazines. There was a problem of providing a program guide.

  The present invention relates to a digital broadcast receiving apparatus that generates electronic program guide data from a digital broadcast signal including program information and displays a part of the electronic program guide data on a monitor in a horizontal direction or a channel transmitted from a broadcasting station. An on-screen signal generating means for generating an on-screen signal for displaying the program information in a section determined by the channel and the time zone, with one axis in the vertical direction and the time zone as the other axis in the horizontal direction or the vertical direction; Determining means for determining whether there are a plurality of channels broadcast from the broadcasting station in a certain time zone and program information in each channel is different, the on-screen signal generating means, There are multiple channels broadcast from the same broadcasting station by the judging means, and each channel If the definitive program information is determined to differ, in the compartment which is determined by the channel and time zone, characterized in that it generates an on-screen signal indicating that further plurality of channels are present. According to the present invention, the determination means for determining whether there are a plurality of channels broadcast from the broadcasting station in a certain time zone and the program information in each channel is different, and the determination means If it is determined that there are multiple channels broadcast from the broadcasting station and the program information in each channel is different, it is displayed that there are multiple channels in the section determined by the channel and time zone Even if a plurality of channels are assigned to one broadcasting station and different programs are broadcasted in the time zone that is each channel, many broadcasting stations Information can be displayed on a monitor. Further, according to the present invention, it is possible to immediately determine whether a broadcasting station in a certain time zone is broadcasting different programs on a plurality of channels. Further, in the present invention, when a broadcasting station in a certain time zone broadcasts different programs on a plurality of channels, the programs broadcast on each of the plurality of channels are divided into sections determined by the time zone and the channels. The program information can be displayed, and an electronic program guide can be realized without reducing the information of the broadcasting station displayed on the monitor. Further, in the present invention, when it is determined that there are a plurality of channels in a section determined by the channel and the time zone and the program information in each channel is different, the programs of the plurality of channels existing in the section. Information can be displayed, and a list display of program information of a plurality of channels can be realized.

  According to the present invention, the determination means for determining whether there are a plurality of channels broadcast from the broadcasting station in a certain time zone and the program information in each channel is different, and the determination means are the same. If it is determined that there are multiple channels broadcast from the broadcasting station and the program information in each channel is different, it is displayed that there are multiple channels in the section determined by the channel and time zone Even when a plurality of channels are assigned to one broadcasting station and different programs are broadcast in the time zone that is each channel, the broadcasting information display means for Information can be displayed on a monitor.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing an embodiment of a digital broadcast receiver of the present invention, and FIG. 2 is a diagram showing an example of a program table by the digital broadcast receiver of the present invention. In FIG. 1, a digital broadcast wave input from an antenna 101 is received by a reception demodulator 102, and a signal modulated in the transmission process is demodulated into a baseband bit stream signal. If this bit stream signal is a scrambled signal, the descrambler 103 releases the scramble and inputs it to the demultiplex / AV decoding unit 104. The demultiplex / AV decoding unit 104 separates the video signal and audio signal from the additional information such as program information, and decodes and outputs the video signal and audio signal. The additional information is captured by the microprocessor 105 and stored in the memory 108. For example, when the user operates the remote control transmitter 107 to display a program guide, the microprocessor 105 reads additional information from the memory 108 and controls the on-screen signal generator 109 to display a program guide as described later. Generate an on-screen signal. Here, the on-screen signal is a video signal or a still image signal superimposed on the video signal output from the demultiplex / AV decoding unit 104. The synthesizer 110 synthesizes the video signal and the program guide output from the on-screen signal generator 109. The video signal is output to the monitor 111. The audio signal is supplied to an audio output device such as a speaker (not shown). The present invention is characterized in the program table generated by the on-screen signal generation unit 109, and an example thereof is shown in FIG. FIG. 2 is a program guide that is generated and displayed by the digital broadcast receiver of the present invention on the electronic program guide that is broadcast in the organization shown in FIG. As shown in FIG. 4, the broadcasting station A broadcasts different programs on the allocated three channels in the time zone from 10:00 to 11:00. The same applies to the time zone from 00:00 to 01:00. In addition, a program having the same program information, that is, the same program is broadcast in the time zone of 11:00 to 00:00 and the time zone of 01: 0 to 02:00. Similarly, the broadcasting station B is assigned two channels, and broadcasts different programs on the two channels in the same time zone, and broadcasts the same program in different time zones. The channel assigned to the broadcasting station C is one channel. In the present invention, it is determined whether or not program information transmitted on a plurality of channels assigned to a broadcasting station is different from each other in the same time zone. Is displayed. In the sections shown as 201, 202, and 203 in FIG. 2, the thickness of the dividing line at the right end of the section is displayed differently from other dividing lines. For example, section 201 indicates that broadcast station A is broadcasting news A in the time zone from 10:00 to 11:00, but is also broadcasting a program different from news A at the same broadcast station A. ing. A section 204 indicates that the broadcasting station A broadcasts only the movie A in the time zone from 01:00 to 02:00. In this way, it is determined whether or not the program information transmitted on the plurality of channels assigned to the broadcasting station is different from each other in the same time zone. By displaying that the channel exists, the information on the broadcast station displayed on the monitor 111 is not reduced.
