Is a time difference determining means for determining whether or not there is a difference between the reservation start time and the reservation end time included in the reservation setting information of the selected program, and the output of the simulcast determination means and the time Reservation setting information changing means for changing the reservation setting information based on the output of the difference determination means, and the plurality of analog channels. An analog video / audio information acquisition unit that selects a corresponding analog channel based on the reservation setting information and acquires analog video / audio information from the analog broadcast signal received by the analog broadcast reception unit. It is characterized by.

  According to the program reservation apparatus of the present invention, the digital broadcast information acquisition unit acquires the digital broadcast electronic program guide information at a frequency higher than the analog broadcast information acquisition unit acquires the analog broadcast electronic program guide information. In addition, when the program selected for the reservation from the analog broadcast electronic program guide information is a simulcast, the broadcast start time and the broadcast end time obtained from the digital broadcast electronic program guide information of the selected program Each of which is different from each of the reservation start time and reservation end time included in the reservation setting information of the selected program, and when it is determined that there is a difference, the electronic program guide information for digital broadcasting Since the reservation setting information is changed based on the program, some or all of the reserved program is recorded even if the broadcast time of the selected program is changed. Be or fails to watch may become possible to obtain an effect of suppressing.

  Hereinafter, the program reservation apparatus according to the embodiment of the present invention, in the case where a so-called simulcast, in which the same program is broadcast at the same time even in digital broadcasting, is performed on at least a part of the analog broadcast program, explain.

  Note that television broadcast stations that transmit analog broadcast electronic program guide information, usually called EPG (Electronic Program Guide) for analog broadcasts, are determined by specific stations in each region in Japan, and several times a day. Since the electronic program guide information of all analog channels that can be viewed in the area is transmitted at a predetermined time, even in this embodiment, a specific analog broadcasting television broadcasting station is several times a day. To be transmitted at a predetermined time.

  In the case of digital broadcasting, the digital broadcast electronic program guide information relating only to the program of the own station is transmitted for each television broadcast station in approximately real time at a predetermined timing at a rate of about once every 1 to 60 seconds. Therefore, also in this embodiment, a program reservation apparatus according to an embodiment of the present invention will be described below on the premise that digital broadcast electronic program guide information is transmitted in substantially real time.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the first embodiment of the program reservation apparatus according to the present invention.

As shown in FIG. 1, the radio signal received by the antenna 1 includes an analog broadcast signal of a plurality of analog channels and a digital broadcast signal of a plurality of digital channels. The unit 2 selects and receives a necessary analog channel from among a plurality of analog channels, and outputs an analog broadcast signal. The analog video / audio encoding unit 3 for analog video / audio information acquisition means acquires analog video / audio information from the output analog broadcast signal, encodes it into a method for recording and viewing on a display, and analog Output to the broadcast reserved program output unit 4.

  Further, the analog broadcast receiving unit 2 receives an analog broadcast signal including the analog broadcast electronic program guide information transmitted at a predetermined frequency from a specific station several times a day, and the analog broadcast information acquisition means A certain analog broadcast EPG acquisition unit 5 a acquires the analog broadcast electronic program guide information, which is EPG information of the analog broadcast, from the analog broadcast signal, and outputs it to the reservation setting unit 6.

  The reservation setting unit 6 selects a program to be reserved from the analog broadcast electronic program guide information. Specifically, the content of the analog broadcast electronic program guide information is displayed on a monitor (not shown) connected to the program reservation device by an operation from a user interface (not shown), and the user is displayed on the screen. When the program to be reserved is selected, the reservation setting unit 6 sets reservation setting information including an analog channel, a recording start time, and a recording end time of the program selected for reservation. The data is output to the reservation adjustment unit 7a.

  On the other hand, the radio signal received by the antenna 1 includes digital broadcast signals of a plurality of digital channels, but the digital broadcast receiving unit 8a is necessary among the plurality of digital channels from the radio signals. The digital channel to be selected is selected and received, and a digital broadcast signal is output.

  By the way, in the case of digital broadcasting, the digital broadcast electronic program guide information relating only to the program of the own station is transmitted for each television broadcast station in substantially real time through a channel determined for each television broadcast station. Therefore, the digital broadcast receiving unit 8a selects and receives the digital channel of each television broadcast station, and the digital broadcast EPG acquisition unit 9a receives the digital broadcast EPG information from each of the received digital broadcast signals. The broadcast electronic program guide information is acquired, and the digital broadcast electronic program guide information is output to the reservation adjusting unit 7a.

  The digital broadcast electronic program guide information of each TV broadcast station includes information about the respective digital channels, the broadcast start time of the program, and the broadcast time length of the program. The digital channel of the program, the broadcast start time, and the broadcast end time obtained by adding the broadcast time length to the broadcast start time can be obtained.

  The frequency at which the digital broadcast EPG acquisition unit 9a, which is a digital broadcast information acquisition unit, periodically acquires the digital broadcast electronic program guide information is at least as high as that of the analog broadcast EPG acquisition unit 5a, which is an analog broadcast information acquisition unit. It sets so that it may become higher than the frequency which acquires electronic program guide information for predetermined time.

  Then, in the reservation adjusting unit 7a, for each reserved program included in the reservation setting information output from the reservation setting unit 6, the digital broadcast electronic program guide information acquired by the digital broadcast EPG acquisition unit 9a. Based on the above, it is determined whether or not the same program as the reserved program is a so-called simulcast that is also broadcast in analog broadcast at the same broadcast start time and the same broadcast end time.

  As described above, the frequency at which the digital broadcast EPG acquisition unit 9a acquires the digital broadcast electronic program guide information is set higher than the frequency at which the analog broadcast EPG acquisition unit 5a acquires the analog broadcast electronic program guide information. Has been. Therefore, if the broadcast time of the program is changed after the user reserves the program in the reservation setting unit 6, if the program is a simulcast, the digital broadcast electronic program guide updated by the change of the broadcast time Because it is possible to know the change in the broadcast time of the program based on the information, it is more obvious that there was a change compared to the case of only from the analog broadcast electronic program guide information that is updated only a few times a day You can know for sure.

  Based on the reservation setting information updated with the change of the broadcast time in the simulcast in the reservation adjusting unit 7a, the reservation adjusting unit 7a, when the reservation start time of the reserved program is reached, the analog channel on which the program is broadcast The analog broadcast receiving unit 2 is instructed to select and receive the signal, and the analog broadcast receiving unit 2 is reserved from the analog broadcast signals of a plurality of analog channels included in the radio signal received by the antenna 1. The analog broadcast signal of the analog channel of the program is selected and output.

  The analog broadcast signal of the reserved program output from the analog broadcast receiving unit 2 is extracted as analog video / audio information by the analog broadcast video / audio encoding unit 3 and then encoded into a format for recording and viewing on a display. Then, it is output to the analog broadcast reserved program output unit 4.

  On the other hand, the reservation adjusting unit 7a receives the analog video / audio information encoded and output from the analog broadcast video / audio encoding unit 3 and outputs an analog broadcast video / audio output signal from the reservation start time. The analog broadcast reserved program output unit 4 is instructed.

  Next, when the reservation end time is reached, the reservation adjusting unit 7 a ends the instruction of selective reception to the analog broadcast receiving unit 2 and outputs an analog broadcast video / audio output signal to the analog broadcast reserved program output unit 4. Exit.

  FIG. 2 is a flowchart for explaining the operation of the reservation setting unit 7a in more detail. In the following, with reference to FIG. 2, how the reservation adjusting unit 7 a changes when the broadcast time of the reserved program is changed after the reservation with respect to the reservation setting information set by the reservation setting unit 6. The operation will be described in more detail.

  In FIG. 2, when the reservation adjustment unit 7a shown in FIG. 1 starts reservation adjustment at the reservation adjustment start S11, first, for each reserved program included in the reservation setting information sent from the reservation setting unit 6 Based on the digital broadcast electronic program guide information acquired by the digital broadcast EPG acquisition unit 9a, it is determined in S12 whether each reserved program is a simulcast. For a reserved program that is a simulcast, the reservation start time and the reservation end time of the reserved program obtained from the reservation setting information are displayed for the reserved program obtained from the digital broadcast electronic program guide information that is an EPG for digital broadcasting. In comparison with the broadcast start time and the broadcast end time, it is determined in S13 whether there is a difference between them. If there is a difference, it is determined that the broadcast time of the reserved program has been changed, and in S14, the broadcast start time obtained from the digital broadcast electronic program guide information on the reservation start time and reservation end time information included in the reservation setting information Then, the process is changed to the broadcast end time, and the process in the reservation adjustment unit 7a ends in the reservation adjustment end S15.

  If it is determined in S12 that the reserved program is not simulcast, the processing in the reservation adjustment unit 7a is immediately ended in reservation adjustment end S15. Further, in S13, the reservation start time and reservation end time of the reserved program that is simulcast are compared with the broadcast start time and broadcast end time of the reserved program obtained from the digital broadcast electronic program guide information. If it is determined that there is no change, it is determined that there is no change in the broadcast time of the reserved program, and the processing in the reservation adjustment unit 7a is immediately terminated in the reservation adjustment end S15.

  FIG. 3 is a reservation table showing an example of reservation adjustment of reservation setting information of the program reservation apparatus according to the first embodiment of the present invention.

  In the reservation setting unit 6 shown in FIG. 1, a simultaneous broadcast program from 9:00 to 11:00 is reserved by the user. As a result, reservation setting information having the contents shown on the left side of FIG. It is assumed that it has been output to the reservation adjustment unit 7a. After that, there is a change in the broadcast time of the reserved program. From the digital broadcast EPG information, that is, the digital broadcast electronic program guide information, the broadcast start time of the reserved program is 10 as shown in the center of FIG. When the information that the broadcast end time is 12:00 is acquired, the reservation adjusting unit 7a determines that the reserved program is a simulcast, and further, an electronic program for digital broadcasting It is determined that the broadcast start time and the broadcast end time obtained from the table information are different from the reservation start time and the reservation end time of the reserved program included in the reservation setting information, respectively. 3, the reservation start time of the reserved program in the reservation setting information is changed to 10:00 and the reservation end time is changed to 12:00. Therefore, the analog broadcast video output signal corresponding to the analog channel of the reserved program is output from the analog broadcast reserved program output unit 4 of the program reservation apparatus shown in FIG.

  Since the program reservation apparatus according to the first embodiment of the present invention is configured as described above, it may fail to record a part or all of the reserved program even if the broadcast time of the selected program is changed. The effect that there is no loss of viewing can be obtained.

  In the above, the reservation adjusting unit 7a changes the reservation start time and reservation end time of the program set in the reservation setting information when the broadcast time of the simulcast program is changed in the reservation setting information. The program was changed to the broadcast start time and broadcast end time obtained from the electronic program guide information for the digital broadcast, but obtained from the electronic program guide information for digital broadcasting rather than the reservation start time set in the reservation setting information. If the broadcast start time after the change is earlier, only the reservation start time of this program set in the reservation setting information is changed to the changed broadcast start time obtained from the digital broadcast electronic program guide information. If it does, there are the following effects.

  In other words, the broadcast start time and broadcast end time of the reserved simulcast program are changed so as to be earlier, and only the reservation start time of this program set in the reservation setting information is obtained from the electronic program guide information for digital broadcasting. Even if the broadcast start time and broadcast end time of this program have been restored to the original after the broadcast start time has passed since the change, the reservation end time Since no change is made in the original, there is an effect that it is possible to prevent the latter half of the program from being recorded or viewed.

  FIG. 4 is a flowchart for explaining the operation of the reservation adjusting unit 7a in the above case in more detail.

  In FIG. 4, when the reservation adjustment unit 7a starts reservation adjustment at reservation adjustment start S21, first, EPG for digital broadcasting is acquired for each reserved program included in the reservation setting information sent from the reservation setting unit 6. Based on the digital broadcast electronic program guide information acquired by the section 9a, it is determined in S22 whether each reserved program is a simulcast. For a reserved program that is a simulcast, the reservation start time of the reserved program obtained from the reservation setting information is compared with the broadcast start time of the reserved program obtained from the electronic program guide information for digital broadcasting, and the current reservation In S23, it is determined whether or not the broadcast start time obtained from the digital broadcast electronic program guide information which is an EPG for digital broadcast is earlier than the start time. If it is determined that the broadcast start time obtained from the digital broadcast electronic program guide information is earlier, in S24, only the reservation start time information included in the reservation setting information is obtained from the digital broadcast electronic program guide information. The program is changed to the broadcast start time of the reserved program obtained, and the process of the reservation adjustment unit 7a is ended in reservation adjustment end S25.

  If it is determined in S22 that the reserved program is not simulcast, the processing in the reservation adjustment unit 7a is immediately ended in reservation adjustment end S25. In S23, if it is not determined that the broadcast start time of the reserved program obtained from the digital broadcast electronic program guide information is earlier than the reservation start time of the reserved program that is a simulcast, the reserved program In the reservation adjustment end S25, the processing in the reservation adjustment unit 7a is immediately ended.

  FIG. 5 is a reservation table showing an example of reservation adjustment of reservation setting information of another program reservation apparatus according to the first embodiment of the present invention.

  In the reservation setting unit 6 shown in FIG. 1, a 10:00 to 12:00 simultaneous broadcast program is reserved by the user. As a result, reservation setting information having the contents shown on the left side of FIG. It is assumed that it has been output to the reservation adjustment unit 7a. Thereafter, there is a change in the broadcast time of the reserved program. From the digital broadcast EPG information, that is, the digital broadcast electronic program guide information, the broadcast start time of the reserved program is shown in the center of FIG. When the information that 9:00 and the broadcast end time is 11:00 is acquired, the reservation adjusting unit 7a determines that the reserved program is a simulcast, and further, digital broadcasting electronic When it is determined that the broadcast start time obtained from the program guide information is earlier than the reservation start time of the reserved program included in the reservation setting information, as shown on the right side of FIG. Only the reservation start time of the reserved program is changed to 9:00. On the other hand, the reservation end time remains at 12:00. Accordingly, an analog broadcast video output signal corresponding to the analog broadcast channel of the reserved program is output from 9:00 to 12:00 from the analog broadcast reserved program output unit 4 of the program reservation apparatus shown in FIG. It becomes.

  Since another program reservation apparatus according to the first embodiment of the present invention is configured as described above, the broadcast start time and broadcast end time of the reserved simulcast program are changed so as to be temporarily advanced, Only the reservation start time of this program set in the reservation setting information is changed to the changed broadcast start time obtained from the digital broadcast electronic program guide information, and after the broadcast start time has passed, Even if the broadcast start time and broadcast end time have been restored, the reservation end time remains unchanged and the latter half of the program is not recorded or viewed. There is an effect that there is no loss.

  Unlike the above, when the changed broadcast start time obtained from the digital broadcast electronic program guide information is later than the reservation start time set in the reservation setting information, it is set in the reservation setting information. If only the reservation end time of this program is changed to the changed broadcast end time obtained from the digital broadcast electronic program guide information, the following effects are obtained.

  That is, the broadcast start time and broadcast end time of the reserved simulcast program are changed so as to be delayed once, and only the reservation end time of this program set in the reservation setting information is obtained from the digital broadcast electronic program guide information. It is changed to the obtained broadcast end time after the change, and then the broadcast start time and broadcast end time of this program are restored to the original, and the digital broadcast electronic program guide by the digital broadcast EPG acquisition unit 9a by the broadcast start time Even if the information is not acquired, the reservation start time remains unchanged and the first half of this program is not recorded or watched. effective.

  FIG. 6 is a flowchart for explaining the operation of the reservation adjusting unit 7a in the above case in more detail.

  In FIG. 6, when the reservation adjustment unit 7a starts reservation adjustment at the reservation adjustment start S31, first, EPG for digital broadcasting is acquired for each reserved program included in the reservation setting information sent from the reservation setting unit 6. Based on the digital broadcast electronic program guide information acquired by the section 9a, it is determined in S32 whether or not each reserved program is a simulcast. For a reserved program that is a simulcast, the reservation end time of the reserved program obtained from the reservation setting information is compared with the broadcast end time of the reserved program obtained from the digital broadcast electronic program guide information, and the current reservation In S33, it is determined whether or not the broadcast end time obtained from the digital broadcast electronic program guide information that is the EPG for digital broadcast is later than the end time. If it is determined that the broadcast end time obtained from the digital broadcast electronic program guide information is later, in S34, only the information of the reservation end time included in the reservation setting information is obtained from the digital broadcast electronic program guide information. The program is changed to the broadcast end time of the reserved program obtained, and the processing of the reservation adjustment unit 7a is ended in reservation adjustment end S35.

  If it is determined in S32 that the reserved program is not simulcast, the processing in the reservation adjustment unit 7a is immediately ended in reservation adjustment end S35. In S33, if it is not determined that the broadcast end time of the reserved program obtained from the digital broadcast electronic program guide information is later than the reservation end time of the reserved program that is a simulcast, the reserved program In the reservation adjustment end S35, the processing in the reservation adjustment unit 7a is immediately ended.

  FIG. 7 is a reservation table showing an example of reservation adjustment of reservation setting information of still another program reservation apparatus according to the first embodiment of the present invention.

  In the reservation setting unit 6 shown in FIG. 1, a simultaneous broadcast program from 9:00 to 11:00 is reserved by the user, and as a result, reservation setting information having the contents shown on the left side of FIG. It is assumed that it has been output to the reservation adjustment unit 7a. After that, there is a change in the broadcast time of the reserved program. From the digital broadcast EPG information, that is, the digital broadcast electronic program guide information, the broadcast start time of the reserved program is 10:00, and the broadcast end time is When the information of 12:00 is obtained, the reservation adjusting unit 7a determines that the reserved program is a simulcast, and further ends the broadcast obtained from the electronic program guide information for digital broadcasting. It is determined that the time is later than the reservation end time of this reserved program included in the reservation setting information, and as shown in FIG. 7, the reservation end time of this reserved program in the reservation setting information Only changes to 12:00. On the other hand, the reservation start time remains at 9:00. Accordingly, an analog broadcast video output signal corresponding to the analog broadcast channel of the reserved program is output from 9:00 to 12:00 from the analog broadcast reserved program output unit 4 of the program reservation apparatus shown in FIG. It becomes.

  Still another program reservation apparatus according to the first embodiment of the present invention is configured as described above, so that the broadcast start time and broadcast end time of the reserved simulcast program are changed so as to be delayed once. Thus, only the reservation end time of this program set in the reservation setting information is changed to the changed broadcast end time obtained from the digital broadcast electronic program guide information, and then the broadcast start time and broadcast end time of this program are changed. Even if the digital broadcast EPG acquisition unit 9a has not acquired the digital broadcast electronic program guide information by the broadcast start time, the reservation start time remains unchanged. Since it is not, there is an effect that the first half of the program is not recorded or watched.

Embodiment 2. FIG.
Some TV broadcast stations that transmit digital broadcasts always transmit the exact same program as the analog channel program of a specific TV broadcast station that transmits analog broadcast at the same time as a digital broadcast. Such digital channels of digital broadcasting television broadcast stations and corresponding analog channels are called simulcast channels. That is, all programs broadcast on the analog channel that is a simulcast channel are always broadcast on the digital channel that is a corresponding simulcast channel at the same time.

  In the program reservation apparatus of the first embodiment, it is determined whether or not the reserved program is a simulcast, and when the program is a simulcast, the reservation setting information is based on the digital broadcast electronic program guide information. However, if the analog channel on which the reserved program is broadcast is a simulcast channel, it is possible to view the analog channels that can be viewed without determining whether the program is simulcast. If there is a simulcast channel, the reservation setting information of all programs broadcast on the analog channel that is the simulcast channel is changed based on the electronic program guide information for digital broadcasting If so, at least for the program reserved for that simulcast channel, it is simulcast for each program. Whether it is not necessary to the process of determining performing, it is possible to reduce the processing load.

  FIG. 8 is a block diagram showing an example of the configuration of the second embodiment of the program reservation apparatus according to the present invention. In addition to the configuration of the first embodiment, the program reservation apparatus can be viewed in the area where the program reservation apparatus is located. The analog channel further includes a channel map information creating unit 10 that constitutes a simulcast channel discriminating unit that discriminates whether or not there is a simulcast channel that always transmits simulcast. Also, the same reference numerals as those in FIG.

  In FIG. 8, the analog broadcast electronic program guide information acquired by the analog broadcast EPG acquisition unit 5b and the digital broadcast electronic program guide information acquired by the digital broadcast EPG acquisition unit 9b are channel map information creation units. 10 is input.

  In the channel map information creation unit 10, the analog broadcast electronic program guide information is combined with the digital broadcast electronic program guide information, and so-called channel map information, which is a correspondence relationship between the analog channel and the digital channel, is created. Based on this channel map information, it is determined whether or not there is a digital channel that always broadcasts the same program and contents as the analog channel, and if there is such an analog channel, the analog channel is The simulcast channel information indicating the simulcast channel is sent from the channel map information creating unit 10 to the reservation adjusting unit 7b.

  In the reservation adjusting unit 7b, the reservation setting information sent from the reservation setting unit 6 is judged based on the simulcast channel information sent from the channel map information creating unit 10, and the analog channel of the reserved program is determined. Among them, if there is a simulcast channel, all the programs of the analog channel are changed based on the electronic program guide information for digital broadcasting.

  Since an example of Embodiment 2 of the program reservation apparatus according to the present invention is configured as described above, it is determined whether or not at least a program reserved for the simulcast channel is simulcast for each program. There is no need to perform the determination process, and the processing load can be reduced.

  In addition to the simulcast channel discriminating means provided with the above-described channel map information creating unit 10, the analog video / audio information signal waveform selected and received by the analog broadcast receiving unit 2 is encoded, and the digital broadcast receiving unit 8a. There is a simulcast channel among the analog channels that can be viewed by comparing the signal waveform of the digital video / audio information that has been selected and received and changed in resolution so that it has the same resolution as the analog video / audio information.
