(Embodiment)
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating the configuration of the broadcast receiving apparatus 100 according to the present embodiment.

  The broadcast receiving apparatus 100 of this embodiment includes a digital TV tuner 110, a video distribution communication module 120, and a TV-compatible LSI (Large Scale Integration) 130.

  The digital TV tuner 110 is supplied with an antenna input, receives a terrestrial digital television broadcast signal of a desired channel, obtains an MPEG2-TS (MPEG2-Transport Stream) packet of the reception channel, and supplies it to the TV-compatible LSI 130. .

  The video distribution communication module 120 is connected to the IP network, and converts a signal suitable for communication via Ethernet (registered trademark) in the IP network into a digital signal in the CPU 140 described later. The video delivery communication module 120 performs the reverse conversion. For example, the video distribution communication module 120 receives information from a provider via an IP network, and supplies a TS packet and a communication message (including control information) obtained from the received information to the TV-compatible LSI 130. The video distribution communication module 120 transmits transmission information such as a communication message (including control information) supplied from the TV compatible LSI 130 to the IP network, for example, toward the provider.

  The TV-compatible LSI 130 includes a demultiplexing unit 131, a decoder unit 132, an image superimposing unit 133, and a CPU (Central Processing Unit) 140. The TV compatible LSI 130 demultiplexes the multiplexed TS packets supplied from the digital TV tuner 110 or the video distribution communication module 120 by the demultiplexing unit 131 and supplies the demultiplexed unit 131 to the decoder unit 132.

  The decoder unit 132 decodes the MPEG2-TS packet and converts it into a video signal and an audio signal. The converted video signal is supplied from the video output unit 150 to the television receiver via the image superimposing unit 133, and the converted audio signal is supplied from the audio output unit 160 to the television receiver.

  The CPU 140 generates transmission information such as a communication message (including control information) in response to an input from the operation unit 170 such as a remote controller, and supplies the transmission information to the video distribution communication module 120 for transmission to a provider, for example. . At the same time, the CPU 140 performs control according to a communication message from a provider, for example.

  Further, the CPU 140 generates a superimpose video signal for performing a superimpose display in response to a communication message (including control information) from the provider or an input of a channel selection instruction from the operation unit 170 and the image superimposing unit 133. The image superimposing unit 133 adds the superimpose video signal to the video signal from the decoder unit 131 and superimposes it.

  Further, the CPU 140 performs tuning control of channels to be selected for the digital TV tuner 110 and the video distribution communication module 120, and performs output control of video signals and audio signals of the decoder unit 132. The CPU 140 causes the LED (light emitting diode) 180 to blink when there is an input from the operation unit 170 such as a remote controller. Thereby, the user can recognize that the input from the operation unit 170 has been input reliably.

  Further, the CPU 140 can make reservations for viewing and recording programs as described below using the electronic program guide information superimposed on the digital television broadcast signal. The CPU 140 can realize the functions of the units described below by executing a program stored in a storage device (not shown) of the broadcast receiving apparatus 100.

  FIG. 2 is a diagram illustrating the functional configuration of the CPU 140.

  The CPU 140 includes a program guide information acquisition unit 141, a character string setting unit 142, a priority setting unit 143, a program search unit 144, an extraction unit 145, a reservation table creation unit 146, a list creation unit 147, and a change unit 148.

  The program guide information acquisition unit 141 acquires electronic program guide information superimposed on a digital television broadcast signal. The electronic program guide information is information including program information of each station transmitted from each broadcasting station. The program information includes, for example, information such as program name, broadcast start time, broadcast end time, performer, and program outline.

  The character string setting unit 142 sets, for example, a search character string input by a viewer or the like from the operation unit 170 or the like. The priority setting unit 143 sets the priority input by the viewer or the like from the operation unit 170 or the like, for example.

  The program search unit 144 performs a search process for searching the electronic program guide information acquired by the program guide information acquisition unit 141 using the search character string set by the character string setting unit 142. The extraction unit 145 extracts program information searched by the program search unit 144. The reservation table creation unit 146 uses the program information extracted by the extraction unit 145 to create a reservation table to be described later according to the set priority. In the following description, a program reserved by the reservation table is called a reserved program.

  The list creation unit 147 creates a list using the program information extracted by the extraction unit 145 and not used for creating the reservation table. That is, the list created by the list creation unit 147 is program information of programs other than reserved programs. In the following description, a program that is not reserved in the reservation table is called a reservation candidate program. The changing unit 148 changes the reserved program in the reservation table to a reservation candidate program.

  Next, the operation of the broadcast receiving apparatus 100 of this embodiment will be described. First, creation of a reservation table and a list in the broadcast receiving apparatus 100 will be described. FIG. 3 is a flowchart for explaining creation of a reservation table and a list in the broadcast receiving apparatus 100.

  For example, when an instruction to create a reservation table is input from the operation unit 170, the broadcast receiving apparatus 100 acquires electronic program guide information by the program guide information acquisition unit 141 in step S31. Progressing to step S32 following step S31, the program search unit 144 searches the electronic program guide information with the search character string set by the character string setting unit 142. It is assumed that the search character string is set in the broadcast receiving apparatus 100 before receiving the reservation table creation instruction.

  Progressing to step S33 following step S32, the extraction unit 145 extracts the program information searched by the program search unit 144 from the electronic program guide information. Specifically, for example, when the name of a specific entertainer is set as a search character string in the character string setting unit 141, the program search unit 144 searches for program information including the name of the specific entertainer, and extracts an extraction unit. Reference numeral 145 extracts program information (searched program information) including the name of a specific entertainer.

  Progressing to step S34 following step S33, when there are a plurality of programs corresponding to the extracted program information, the reservation table creating unit 146 determines whether there is a program having an overlapping broadcast time.

  If it is determined in step S34 that there is a program with an overlapping broadcast time, the process proceeds to step S35, and the priority set by the priority setting unit 143 is confirmed. Progressing to step S36 following step S35, the reservation table creating unit 146 selects program information used for creating the reservation table from the program information extracted according to the priority.

  The process of step S35 and step S36 is demonstrated concretely. For example, when the broadcast time of program A broadcast on channel 3 and the broadcast time of program B broadcast on channel 6 overlap, priority setting unit 143 gives priority to the smaller number of channels. Suppose that it has been set. In this case, the reservation table creating unit 146 determines that the priority of the program A having a small number of channels is high, and selects the program information of the program A as program information used for creating the reservation table.

  Further, for example, when the broadcast of program A is started first and the broadcast of program B is started during the broadcast of program A, the priority setting unit 143 is set to give priority to the program with the earlier broadcast start time. Suppose. In this case, the reservation table creation unit 146 determines that the program A is a high priority program and selects program information of the program A.

  For example, when the broadcast time of program A is 1 hour and the broadcast time of program B is 2 hours, the priority setting unit 143 is set to prioritize a program with a long broadcast time. In this case, the reservation table creation unit 146 determines that the program B is a high priority program and selects program information of the program B.

  In the broadcast receiving apparatus 100 of this embodiment, the priority setting unit 143 may set a plurality of patterns of priorities. In addition, the priority setting by the priority setting unit 143 may be initially set, for example, before the broadcast receiver 100 is shipped from the factory. The priority setting by the priority setting unit 143 may be arbitrarily changed by the viewer.

  Returning to FIG. 3, the process proceeds to step S <b> 37 following step S <b> 36, and the reservation table creation unit 146 creates a reservation table. Progressing to step S38 following step S37, the list creation unit 147 creates a list of reserved candidate programs. Specific examples of the reservation table and the list of reservation candidate programs will be described later.

  Specifically, the list creation unit 147 acquires program information other than the program information corresponding to the reserved program from the program information extracted in step S33, and creates a list based on this program information. Progressing to step S39 following step S38, the list creation unit 147 stores the created list in a storage device (not shown) or the like included in the broadcast receiving apparatus 100. Note that the stored list is deleted after a predetermined period, for example. For example, the stored list may be deleted after all the programs reserved in the reservation table are broadcast.

  Here, the reservation table and the list of reservation candidate programs will be described in detail with reference to FIG. FIG. 4 is a diagram illustrating a specific example of a reservation table and a list of reservation candidate programs.

  T1 shown in FIG. 4 is a reservation table created by the reservation table creation unit 146. T2 shown in FIG. 4 is a list of reserved candidate programs created by the list creation unit 147. In the reservation table T1, it can be seen that the program is reserved so that there is no free time between 10:00 and 20:00 by the processing described in FIG. In FIG. 4, the programs reserved in the reservation table T1 are designated as S-1 to S-8. In FIG. 4, the time slot for program reservation is set from 10:00 to 20:00, but the present invention is not limited to this. The time slot for reserving a program can be arbitrarily set by the operation unit 170 or the like.

  In the list T2, reservation candidate programs other than the reserved programs reserved in the reservation table T1 are listed. Reservation candidate programs at the broadcasting station A are A-1 to A-4. Reservation candidate programs at the broadcasting station B are B-1 and B-2. Reservation candidate programs at the broadcasting station C are C-1 to C-3. Reservation candidate programs at the broadcasting station D are D-1 to D-3. Reservation candidate programs at the broadcasting station E are E-1 to E-3. The reservation candidate program at the broadcasting station F is F-1.

  As described above, the broadcast receiving apparatus 100 according to the present embodiment creates a list T2 of reserved candidate programs other than the reserved programs reserved in the reservation table T1, thereby viewing all programs including the set search character string. Can be made to grasp. In this embodiment, the reservation table T1 can be changed using the list T2 of reservation candidate programs.

  The change of the reservation table T1 will be described below with reference to FIG. FIG. 5 is a flowchart for explaining the change of the reservation table.

  In step S51, when a confirmation instruction for the reservation table T1 is input by the operation unit 170, the process proceeds to step S52, and the CPU 140 outputs the reservation table T1 to the television receiver via the video output unit 150, and the television receiver. To display. At this time, the CPU 140 may supply a guidance voice or the like related to the reservation table T1 to the television receiver via the voice output unit 160.

  Following step S52, the process proceeds to step S53. When a reference request for the list T2 is input by the operation unit 170, the process proceeds to step S54, and the CPU 140 outputs the list T2 to the television receiver for display.

  Following step S54, the process proceeds to step S55. When an instruction to change the reserved program to the reserved candidate program is received from the operation unit 170, the process proceeds to step S56, and the changing unit 148 reserves the reserved program instructed to be changed. Change to a candidate program. Details of the processing in step S56 will be described later. Progressing to step S57 following step S56, the reservation table creation unit 146 creates a reservation table again based on the change by the change unit 148.

  In the description of FIG. 5, the list T2 is output when there is a reference request for the list T2 after outputting the reservation table T1, but the present invention is not limited to this. For example, the list T2 may be output simultaneously with the reservation table T1 when a confirmation request for the reservation table T1 is input. In this case, the list T2 is displayed at the same time when the reservation table T1 is displayed on the pre-television receiver.

  Hereinafter, the change in step S56 will be described with reference to FIG. 4 again. The reservation table T1-1 shown in FIG. 4 is created by modifying the reservation table T1.

  The reservation table T1-1 changes the reserved programs S-1 and S-2 of the reservation table T1 to reservation candidate programs A-1 and E-1 in the list T2, and reserves the reserved program S-4 in the list T2. In this example, the program is changed to the candidate program E-2 and the reserved program S-7 is changed to the reserved candidate program E-3 in the list T2. When receiving the instruction to change the reserved program to the reserved candidate program, the changing unit 148 replaces the program information corresponding to the reserved program in the reservation table T1 with the program information corresponding to the reserved candidate program according to the instruction. When the change (change) of the program information by the changing unit 148 is completed, the reservation table creating unit 146 creates the reservation table T1-1 based on the changed program information.

  Specifically, the reservation table creation unit 146 changes the program information corresponding to the reserved programs S-3, S-5, S-6, and S-8 that have not been changed, from the reservation candidate program to the reserved program. The reservation table T1-1 is created based on the program information corresponding to the programs A-1, E-1, E-2, and E-3.

  As with the reservation table T1-1, the reservation table T1-2 shown in FIG. 4 is also created by changing the reservation table T1. In the reservation table T1-2, an example in which an idle time is generated between programs due to the change by the changing unit 148 is shown.

  The reservation table creation unit 146 according to the present embodiment can select a reservation candidate program whose broadcast time is shorter than the free time and change the reserved program to a reserved program when the change unit 148 changes the free time.

  The reservation table T1-2 shows a case where the reserved program S-3 in the reservation table T1 is changed to the reservation candidate programs B-1 and F-1 in the list T2.

  In the case of the reservation table T1-2, an example in which an instruction to change the reserved program S-3 to the reservation candidate program B-1 is received. In this case, the broadcast time of the reserved program S-3 is longer than that of the reservation candidate program B-1, and if a change is made, a free time t occurs before the reserved program S-4. The reservation table creation unit 146 of the present embodiment determines whether there is a reservation candidate program whose broadcast time is shorter than the free time t in the list T2, and if there is a corresponding reservation candidate program, this reservation candidate program Select. In the reservation table T1-2, it can be seen that the reservation candidate program F-1 whose broadcast time is shorter than the idle time t is changed to a reserved program.

  As described above, in this embodiment, the viewer can grasp all program information searched by the search character string set by the viewer regardless of whether or not the reservation is made. Furthermore, in the present embodiment, a reserved program can be changed to a program that is not reserved, and a reservation table can be created again. Therefore, according to the present embodiment, in addition to the automatically reserved program, whether or not there is a program corresponding to the keyword, and if it exists, what kind of contents the program is made to allow the viewer to grasp. It is possible to accurately reflect the viewer's intention in the automatic program reservation.

  In the description of the present embodiment, the description has been made assuming that an instruction for changing a reserved program to a reserved candidate program is input from the operation unit 170, but the present invention is not limited to this. For example, when the priority setting is changed after the reservation table T1 is created, the changing unit 148 of the present embodiment may change the reserved program to the reserved candidate program according to the new priority. Further, the change unit 148 of the present embodiment changes the reserved program to the reservation candidate program according to the search result by the new search character string, for example, when the setting of the character string is changed after the reservation table T1 is created. Also good.

  As mentioned above, although this invention has been demonstrated based on each embodiment, this invention is not limited to the requirements shown in the said embodiment. With respect to these points, the gist of the present invention can be changed without departing from the scope of the present invention, and can be appropriately determined according to the application form.

  The present invention can be used in a broadcast receiving apparatus and a program reservation method for receiving a television broadcast.
