Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Note that the embodiments described below are preferred specific examples of the present invention,
Although various technically preferable limits are given, the scope of the present invention is not limited to these modes unless otherwise specified in the following description.

FIG. 1 shows an example of a broadcast wave broadcast mode to which a broadcast wave information supply method of the present invention and a receiver for receiving a broadcast wave are applied. FIG. 2 is a block diagram of the broadcast mode of FIG. FIG. 1 shows an example of the form of terrestrial broadcasting. However, in terrestrial broadcasting, it is not possible to transmit radio waves from one place and to receive the radio waves wherever they are. This is due to the straightness of the radio wave, and if there is an obstacle such as a mountain in the middle, the radio wave does not reach. The surface of the earth is a sphere, and the further the distance, the more obstructed the earth, and the less radio waves can reach. Another reason that radio waves do not reach is that radio waves attenuate as the distance increases. For this purpose, a broadcasting tower is provided for each area to transmit radio waves. For areas where radio waves still do not reach, a repeater is placed in a place with a good view to complement the area. For this reason, the broadcast stations and frequencies that can be received differ from region to region.

In FIG. 1, for example, three broadcast stations (broadcast contents supply sources) A, B, and C can supply broadcast contents to a broadcast tower T. Repeaters 7 and 8 are set on the mountains M1 and M2, respectively. Broadcast tower T
As for the viewing areas AR1, AR2, AR3, AR4
Is displayed as an example. One broadcast tower T transmits the broadcast waves BW (radio waves) of the above-described plurality of broadcast stations A, B, and C,
It is transmitted directly to the viewing area AR1 and to the repeaters 7 and 8. Since the viewing area AR1 is a place where the broadcast tower T can be seen, the antenna AT of the viewing area AR1 can receive a broadcast wave BW (radio wave) from the broadcast tower T.

On the other hand, viewing areas AR2, AR3, A
Since the broadcast tower T is interrupted by the mountains M1 and M2 with respect to the broadcast tower T, the broadcast tower T is not directly visible. So, the viewing area AR
The second antenna AT receives the broadcast wave BW of the broadcast tower T via the repeater 7. The viewing areas AR3 and AR4 receive the broadcast wave BW via the repeater 8. The viewing area AR3,
The signal can be received from either the repeater 7 or the repeater 8. In any case, each viewing area AR2 to AR4
Can receive broadcast waves via the nearest repeater. In the case of the viewing area AR3, the broadcast waves are received from one of the repeaters, since they are almost at the same distance from the repeaters 7 and 8.

FIG. 3 shows an example in which a plurality of broadcasting towers T are provided. One of the broadcasting towers T has a plurality of broadcasting stations A,
B and C broadcast waves can be received, and another broadcast tower T is broadcast stations D and
E and F broadcast waves are received. One broadcast tower T transmits the broadcast wave BW directly to the repeaters 7, 8 and the viewer 1 in the viewing area AR1. Another broadcast tower T is a repeater 9,
The broadcast wave BW is transmitted to 10. The repeater 7 is in the viewing area A
The broadcast wave BW is transmitted to the viewers 2 and 3 of R2 and the viewer 4 of the viewing area AR3. The repeater 8 transmits the broadcast wave BW to the viewer 4 in the viewing area AR3 and the viewers 5 and 6 in the viewing area AR4. The repeater 9 transmits the broadcast wave BW to the viewers 5 and 6 and the viewer 6A in the viewing area AR5. The repeater 10 transmits the broadcast wave BW to the viewer 6A and the viewers 6B and 6C in the viewing area AR6.

FIG. 4 is an example of a table describing the relationship between a broadcasting tower, a repeater, and a broadcasting station. Broadcast towers T1 and T2 illustrated in FIG. 4 are broadcast wave transmitting facilities, and a broadcast station with a broadcast station number is a broadcast content supply source. Broadcast towers T1 and T2, which are broadcast wave transmission facilities, are shown with corresponding broadcast towers T3 or a plurality of repeaters 7, 8 and the like. In the broadcasting tower T3 and the repeaters 7 and 8, installation locations 12, 13, and 14 are described.

The numbers of the broadcasting stations (broadcast contents supply sources) are described corresponding to the broadcasting tower T3 corresponding to the broadcasting tower T1 or the repeaters 7 and 8, respectively. For example, broadcast tower T
Broadcast stations A, B, and C correspond to 3, and broadcast stations A, B, and C correspond to the repeater 7. Each broadcasting station A, B, C is provided with a corresponding transmission channel number list 15. For example, broadcast station A corresponds to broadcast channel number “30”, broadcast station B corresponds to broadcast channel number “32”, and broadcast station C corresponds to broadcast channel number “34”. This is similarly described in the broadcast tower T2.

In the table 20 formed by such a description method, the transmission frequency list 16 of each broadcasting station is described in correspondence with each broadcasting station. This table 20
Are included in an electronic program guide (EPG) relating to broadcast waves, and the table 20 includes broadcast stations A, B, and C (broadcast contents supply sources) as shown in FIG. 1 or FIG. When transmitting to broadcasters (broadcast content receiving side), the relationship between the broadcast towers T1, T2,..., Which are preferably broadcast wave transmission facilities, and the broadcast stations A, B, C,. It has been described. Moreover, in this table 20, it is preferable that the broadcasting stations A, B, C
.., And at least one of the transmission channel numbers described in the transmission channel number list 15.

The EPG table 20 also includes locations 12, 13, 14 of broadcast wave transmission facilities including broadcast wave repeaters.
It is preferable to further include information indicating the like. The table 20 includes broadcast towers, which are broadcast wave transmission facilities including broadcast wave repeaters as shown in FIG. 6, and areas where the broadcast content receiving side can view (for example, viewing areas AR1, AR2,... Shown in FIG. 1).
..) may be included. In any case, the table 20 in FIG. 4 is included in the electronic program guide EPG, and includes items such as a broadcast base number of a broadcast tower, a repeater number, a repeater location, a broadcast station number, a transmission channel number, and a transmission frequency. It is possible to combine at least two.

By the way, for example, in FIG. 4, the broadcast station number is considerably large, and the same broadcast station is described many times in the table 20 of FIG. For example, broadcast stations A, B, and C are listed as information many times. If the table 20 is described directly in the electronic program guide EPG as described above, the amount of information increases considerably, or the structure of the table 20 becomes complicated.

Therefore, as shown in FIG. 5, for the detailed information of the broadcasting station, the table 21 of FIG.
It is desirable to send it so that it is included in the PG. In FIG. 5, the table 21 has a broadcast station number view 22, a broadcast station name view 23, a series view 24, a location view 25, a type view 26, and other views 27. In the broadcast station number list 22, the broadcast stations A, B, C, D,... Are arranged in order, and in the broadcast station name list 23, the corresponding names are described. .. Belong to which network broadcast series the broadcast stations A, B... The location list 25 describes the location of each broadcasting station, and the type list 26 describes information necessary for reception other than frequencies such as the polarization plane of the radio wave and the radio wave format (modulation method).

In this way, information such as the name of each broadcasting station, the network broadcasting sequence, and the location can be reliably known even if the number of viewers and broadcasting stations in FIGS. 2 and 3 is large. Also, from FIGS. 4 and 5, in order for the viewer to obtain information such as the broadcast station and the transmission channel number, the number of the repeater (broadcast tower or repeater) is previously received by the receiver used by the viewer. You need to know if you can. That is, it is necessary to know which repeater or broadcast tower corresponds to the viewing area shown in FIGS. 2 and 3 where the viewer is located. The table 28 in FIG. 6 assists this. This table 28 is also included in the electronic program guide EPG, and includes a viewing area number reference 29, a repeater number reference 30, an area name reference 31, and a postal code reference 3.
2 is provided. Instead of the postal code page 32, a telephone number page 33 may be provided.

The viewing area number list 29 includes a viewing area AR.
.. Are described side by side. List of repeater numbers 30
, A broadcasting tower, repeaters 7, 8 and the like are arranged. In the area name list 31, the address of each viewing area is described. In the postal code list 32, a postal code corresponding to the address described in the area name list 31 is described. The telephone number list to be described at the same time as or instead of the postal code number 32 is a telephone number corresponding to the area name, and can also describe the telephone number of the viewer.
Thus, the viewer (user) can easily select the viewing area to which the viewer belongs by confirming the area name, the postal code or the telephone number, and the viewing area where the viewer (user) is located. It is possible to easily know which broadcast tower or repeater corresponds to by viewing the repeater number list 30.

By viewing the table 20 shown in FIG. 4, the table 21 shown in FIG. 5, and the table 28 shown in FIG. 6 from the electronic program guide EPG, the viewer can easily obtain information on various broadcasts. You can know.

Next, the tables 20, 20 shown in FIGS.
In the case where 21 and 28 are put on terrestrial broadcasting, for example, the terrestrial broadcasting system shown in FIG. 1 can be used. The broadcast stations A, B, C, etc., which are the broadcast content supply sources, transmit the tables 20, 21, and 28 along with the images and sounds on the same propagation path. That is, broadcast stations A, B and C send broadcast tower T
To transmit the broadcast wave BW to the viewing area AR1, the repeater 7, and the repeater 8. The broadcast wave BW includes content information of a broadcast program and an electronic program guide EPG, and the electronic program guide EPG includes tables 20, 21, and 28, for example. As described above, when the transmission is performed on the same propagation path, the electronic program guide EPG is transmitted in the broadcast wave BW at a frequency different from the information of the image and the sound. Alternatively, the electronic program guide EPG can be inserted in a blanking section of the image, or can be placed on a subcarrier used in FM (frequency modulation) multiplexing or audio multiplexing. When transmitting video and audio by digital broadcast waves, the electronic program guide EPG (tables 20, 21, and 20) shown in FIGS.

The G information and the digital video / audio signal are sent to the modulator 54, modulated, amplified by the high frequency power amplifier 55 to a transmission output sufficient for broadcasting, and then transmitted from the antenna 46.

FIGS. 9 and 10 show an example of a broadcast wave receiving apparatus. FIG. 9 shows an example of a broadcast wave receiving apparatus used by the viewer of FIG. 2 in the terrestrial broadcast system of FIG. 1, for example. This broadcast wave receiving device 60 can be used, for example, in the case of analog broadcasting. The receiving device 60 has the following structure. The broadcast wave BW (radio wave) received by the antenna 61 is sent to the tuner 62. As the broadcast wave BW input from the antenna 61, a radio wave of a specific frequency is selected by the tuner 62 according to an instruction from the host processor 63. Table 2 in FIGS. 4 to 6
When acquiring 0, 21, and 28, the tuner 62 selects the frequency at which the table exists from the broadcast waves BW. The selected radio signal from the tuner 62 enters the demodulation unit 64 and the demodulated signal is demodulated. The video signal 66 is extracted by the video signal extraction unit 65 and passes through the superimposition (superimpose) unit 67 for screen display. VS. The signal from the demodulation unit 64 is converted into an audio signal AS by the audio demodulation unit 68. The video signal VS and the audio signal AS are sent to, for example, a television receiver 69. The audio signal AS is sent to an audio signal reproducer 70 such as a radio.

On the other hand, among the selected signals output from the demodulation section 64, the signals relating to the tables 20, 21, and 28 in FIGS. 4, 5, and 6 are descrambled by the descrambler section 71 to release the reception restriction. The processing is performed to obtain a digital signal. Thereafter, the digital signal relating to the table is demodulated by the demultiplexer 72, and the signal of the table required at that time is sent to the host processor 63 and the EPG processor 73. The host processor 63 can send processing signals to the tuner 62, the descrambler 71, the demultiplexer 72, and the EPG processor 73. The host processor 63 is connected to an input section 74 for inputting a postal code or a telephone number. The digital signal related to the table output from the demultiplexer 72 is sent to a computer 74A, and the computer 74A uses a printer 75 to output the digital signal shown in FIG.
Tables 20, 21, and 28 as shown in FIGS. 5 and 6 can be printed out, and these tables can be displayed on the monitor 76.

The contents of the digital signal relating to the table are analyzed by the host processor 63, and the music selection, E
A display digital signal used for PG display or the like is created. This digital signal for display is sent from the host processor 63 to the screen display superimposing section 67 via the EPG processor 73. The screen display superimposing section 67 superimposes the video signal 66 from the video signal extracting section and the digital signal used for the music selection and the EPG display, for example, to form the video signal VS, thereby forming the television receiver 69 Send to On the screen of the television receiver, based on this video signal VS, for example, a table 20 in FIG. 4 or a table 21 in FIG.

The name of the broadcasting station, the number of transmission channels, the number of transmission frequencies, the address of the broadcasting tower and the repeater, etc., which can be received by the receiver currently used by the user are automatically set in the receiver.

FIG. 11 is different from FIG. 1 in that not only terrestrial broadcasting but also broadcasting stations A, B and C supply a broadcasting tower B and a parabolic antenna PA with a broadcasting wave BW including the contents of broadcasting. The broadcast tower T or the parabolic antenna PA transmits the broadcast wave BW, but the broadcast wave BW transmitted by the parabolic antenna PA is relayed by the transponder 102 of the broadcast satellite 101 and, for example, transmitted to the parabolic antenna PA1 in the viewing area AR10. Parabolic antenna PA of area AR11
1 can transmit a broadcast wave BW. On the contrary,
The broadcast wave BW transmitted from the broadcast tower T corresponds to the viewing area AR1.
0 and the antennas 61 and 81 of the AR 11 can be received. Thus, the broadcast wave BW transmitted from the parabolic antenna PA can be received by the parabolic antenna PA1 of each home via the transponder 101. Broadcast tower T
Is transmitted directly to the antennas 61, 81 of the viewing area AR10 or via the repeater 8 of the mountain M1 to the respective antennas 61, 8 of the viewing area AR11.
1 can be sent. In this case, as the transmitting device, the transmitting devices 40 and 50 shown in FIGS. 7 and 8 can be used.

In the case of transmitting by terrestrial wave shown in FIG. 1, information must be reliably transmitted even through a repeater.
However, in the case of transmission by an analog repeater, when the signal passes through the repeater many times, distortion gradually increases, and information may be lost. Even when presetting a television receiver, it is necessary to be able to receive radio waves, but it must be received until the nearest radio wave transmission location (broadcasting tower or repeater) is known. Can not. In the case of using a point broadcasting satellite or the like, the same broadcast wave (radio wave) can be reliably received no matter where the user is located.
