Thereafter, when the operation button is operated, the channel selection operation is performed using the channel selection information for selecting the program assigned to the operated operation button.

  According to the present invention, the program information is searched with the search condition registered for the operation button, the program satisfying the search condition is assigned in advance to the operation button corresponding to the search condition, and the operation button is operated. When a channel is selected, a channel selection operation is performed using channel selection information for selecting a program assigned to the operated operation button.

  For this reason, when viewing a program of a desired genre or a program having a desired keyword, it is not necessary to perform a search by inputting a genre or a keyword each time, and a program satisfying the search condition can be quickly viewed. Can do. In addition, since the search condition is registered in the operation button, only the program satisfying the desired search condition can be easily viewed simply by operating the operation button in which the desired search condition is registered.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration of a broadcast receiving apparatus that receives a television broadcast.

  The receiving unit 11 of the broadcast receiving apparatus 10 includes a tuner / demodulating unit 111 and a TS separating unit 112. The receiving unit 11 supplies program data of a channel designated by the control unit 40 described later to the program presentation processing unit 12.

  The tuner / demodulator 111 selects a signal having a frequency used for transmission of a designated channel from a received signal RF obtained by receiving a television broadcast using an antenna (not shown). Generate a frequency signal. Further, digital demodulation, error correction, deinterleave processing, descrambling processing, and the like are performed on the intermediate frequency signal, and the obtained transport stream TS is supplied to the TS separation unit 112.

Further, when a packet of an information signal DTc or a data broadcast signal DTd having channel selection information for selecting a program and program information related to the program is obtained, the information signal DTc and the data broadcast signal DTd are supplied to the control unit 40. To do.

  The program presentation processing unit 12 includes a video decoder 121, an audio decoder 122, a video output processing unit 123, an audio output processing unit 124, and the like. Based on the program data supplied from the receiving unit 11, a video output signal and audio output Generate and output a signal.

  The video decoder 121 decodes the video data DTv and supplies the decoded video data DV to the video output processing unit 123 and the storage device 33. The video output processing unit 123 is a video plane signal for displaying video of a program broadcast on a designated channel, a still image plane signal for displaying a still image, and a character graphic for displaying characters and graphics. Generation, switching, and mixing of a plane signal and a caption plane signal for displaying a caption are performed, and a video output signal Vout is generated and supplied to the display device 13. Note that the still image plane signal, the character graphic plane signal, and the caption plane signal are generated by the video output processing unit 123 using a signal supplied from the control unit 40 described later or based on an instruction from the control unit 40.

  The audio decoder 122 decodes the audio data DTa and supplies the decoded audio data DA to the audio output processing unit 124 and the storage device 33. The audio output processing unit 124 converts the audio data DA supplied from the audio decoder 122 into an analog signal, adjusts the signal level, etc., and supplies it to the speaker 14 as an audio output signal SAout.

  The display device 13 performs video display based on the video output signal Vout, and displays video of a program broadcast on a designated channel. It also displays an electronic program guide. The speaker 14 outputs the sound of the program broadcast on the designated channel based on the sound output signal SAout.

  The receiving unit 11 and the program presentation processing unit 12 are connected to the control unit 40 via the bus 20. In addition, an input unit 31, a storage device 33, and a communication unit 35 are connected to the bus 20.

  The input unit 31 includes a remote control signal receiving unit that receives a signal transmitted from the operation button or the remote control device 50. The input unit 31 and the remote control device 50 constitute an operation means. When an operation button provided on the input unit 31 is operated by a viewer, an operation signal PS corresponding to the operated button is generated. This is supplied to the control unit 40. Further, when the remote control device 50 is operated by the viewer and a remote control signal is transmitted from the remote control device 50, the remote control signal is received by the input unit 31 in accordance with the operation of the remote control device 50. The operation signal PS is supplied to the control unit 40. The input unit 31 and / or the remote control device 50 are provided with operation buttons for easily selecting a program of a specific genre or a program including a desired keyword.

  The storage device 33 stores video data and audio data of a program broadcast on the selected channel. The communication unit 35 is for performing interactive service of data broadcasting, transmission / reception of management data in limited reception, and is connected to a public communication line or the like. In addition, channel selection information for selecting a program of each channel in television broadcasting and program information related to the program can be acquired via the communication unit 35. Accordingly, the receiving unit 11 and the communication unit 35 described above also function as information acquisition means.

  The control unit 40 stores channel selection information and program information supplied from the reception unit 11 by the information signal DTc in a memory. Further, the control unit 40 processes the data broadcast signal DTd from the receiving unit 11. Furthermore, the control unit 40 controls the operations of the receiving unit 11, the program presentation processing unit 12, and the like based on the operation signal PS so that the operation of the broadcast receiving device 10 becomes an operation according to the button operation of the viewer. The memory for storing channel selection information and program information may be built in the control unit 40 or provided separately from the control unit 40. In FIG. 1, the memory 40a is built in the control unit 40. Is shown. The control unit 40 has a clock function and is configured to acquire the current time.

  Here, the control unit 40 performs processing using the channel selection information and the program information stored in the memory so that the program of the desired channel can be easily selected.

  In the channel selection information, table information indicating the configuration of each channel for extracting packets such as video data and audio data for each channel from the transport stream TS, and a transport stream TS including a packet of a desired program For example, frequency information indicating the frequency of a signal selected by the tuner / demodulator 111 is shown. For this reason, the control unit 40 uses the channel selection information stored in the memory 40 a to select the channel selection control based on the frequency information for the tuner / demodulation unit 111 and the table information for the TS separation unit 112. By performing the packet separation control based on this, it becomes possible to select a desired program. In digital broadcasting, information such as PAT (Program Association Table), PMT (Program Map Table), and NIT (Network Information Table) is used as channel selection information.

  In the program information, information such as the time, title, genre, and broadcast content of the broadcast program is shown. Therefore, the control unit 40 controls the operation of the video output processing unit 123 using the program information stored in the memory 40a, thereby displaying the electronic program guide on the display device 13, searching for programs, and making reservations. In addition, it is possible to check the contents. In digital broadcasting, information such as BIT (Broadcaster Information Table) and SDT (Service Description Table) is used as program information.

  Further, the control unit 40 registers a search condition for the operation buttons provided in the input unit 31 and / or the remote control device 50, searches for program information using the search condition, and detects a program that satisfies the search condition. Then, the detected program is assigned to the operation button. Here, when an operation button to which a program is assigned is operated, the control unit 40 designates a channel for the reception unit 11 using channel selection information for selecting the assigned program, and performs an operation. The video and audio of the program assigned to the button are presented on the display device 13 and the speaker 14.

  Next, the operation of the broadcast receiving apparatus 10 will be described. The control unit 40 receives an information signal indicating channel selection information or program information when the reception unit 11 receives an information signal indicating channel selection information or program information by receiving a digital broadcast, or via the communication unit 35. When supplied, the channel selection information and program information are stored in the memory 40a.

  FIG. 2 exemplifies the contents shown in the program information as a list. In FIG. 2, programs broadcast on each channel are shown in association with information on program contents at each broadcast time. In addition, “title name”, [genre], and (performer) are illustrated as information on program contents.

  This list indicates that, for example, a program belonging to the title “OO Special” and the genre [Liberal Arts] is broadcast from 17:00 to 18:00 on the channel CH-n1. In addition, it is shown that from 18:00 to 19:00, a program belonging to the title name “Trip no ***” and the genre [variety] is broadcast. Moreover, it has shown that the performer of this program is a performer (* kawa * ro, * yama * mi). Similarly, the other channels CH-n2 to CH-n6 indicate title names, genres, and the like. Although not shown, the program information includes information such as the broadcast contents and the broadcaster name, and these can also be displayed.

  FIG. 3 shows the remote control device 50. The remote control device 50 is provided with buttons to which various functions are assigned. For example, a power button 511 to which a function for turning on / off the power is assigned, a numeric button group 512 to which a channel is assigned, a button 513 to which a channel up / down function is assigned, and a volume up / down function are assigned. Button 514 is provided. In addition, an up / down / left / right button 515 and an enter button 516 used for menu selection, display of an electronic program guide, switching of a broadcasting system, switching of functions of a broadcast receiving apparatus, and the like are provided.

  Furthermore, the remote control device 50 is provided with operation buttons such as a genre button and an allocation button, and the control unit 40 registers search conditions for the genre button and the allocation button. Further, the program information is used to detect a program that satisfies the search condition, and the detected program is assigned or the assigned program is updated. Note that there may be one or a plurality of genre buttons and allocation buttons, and FIG. 3 shows a case where four genre buttons and four allocation buttons are provided.

  Genre buttons 517a to 517d are operation buttons in which genres are registered in advance as search conditions. The allocation buttons 518a to 518d are operation buttons that allow the viewer to freely register search conditions such as genres and keywords. Note that a plurality of genres and keywords can be registered for one button so that AND search and OR search can be performed. The return button 519 is an operation button for returning to a state before the operation button is operated when the operation button for which the search condition is set is operated.

  Here, the genres of “news”, “variety”, “sports”, and “animation” are registered in advance in the genre buttons 517a to 517d as search conditions. Further, it is assumed that, for example, the name of the performer (○ Yamami) is registered as a keyword in one of the allocation buttons 518a to 518d, for example, the allocation button 518d.

  The control unit 40 searches the program information stored in the memory 40a, and at the time before the current time, the program and name (“Yama”) in the genre of “News”, “Variety”, “Sports”, “Anime” ○ Repeat the search process to detect programs that include “beauty”. Further, the control unit 40 associates the program detected by the search process with the previous time and stores it in the memory 40a as a detection result for each search condition. As described above, the search process at the time before the current time is repeatedly performed so that the detection result at the current time is stored in the memory 40a in advance.

  The case where the program information search process shown in FIG. 2 is performed will be described below. The control unit 40 repeatedly performs the search process at a predetermined time interval (for example, every 5 minutes) so that the detection result corresponding to the current time is stored in the memory 40a in advance. When the current time is “17:55”, for example, the times “17:45” to “17:50” are used so that the detection result corresponding to the time range “17: 55 ≦ Tj <18:00” can be used. In the range of “”, a program that satisfies the search condition is detected from the program that starts broadcasting at time “17:55” and the program that is currently broadcasting at time “17:55”. This is because if the search process is started within the range of time “17:45” to “17:50” and the end of the search process is past the time “17:50”, the current time is “ This is because the detection result corresponding to the time range “17: 50 ≦ Tj <17:55” cannot be obtained before 17: 50 ≦ Tj <17:55 ”. The program detection result obtained by performing the search process as described above is stored in the memory 40a in association with the time range “17: 55 ≦ Tj <18:00”.

  Here, the control unit 40 is broadcasting at the time “17:55” and the program that starts broadcasting at the time “17:55” within the range of the time “17:45” to “17:50”. When a program satisfying the search condition is detected from the programs, a program belonging to the [News] genre is broadcast only on channel CH-n5, so the program on channel CH-n5 is related to the time range and genre. Store in the memory 40a. As information stored in the memory 40a in association with the time range and genre, for example, channel numbers and channel selection information for selecting a detected program are used. FIG. 4 shows the detection result stored in the memory 40a, and stores channel selection information TU-n5 for selecting a channel CH-n5 program.

  At time “17:55”, since a program belonging to the [variety] genre is broadcast on channels CH-n3 and CH-n6, channel selection information TU for selecting a channel CH-n3 program is selected. -n3 and channel selection information TU-n6 for selecting a program of channel CH-n6 are stored in the memory 40a in association with the time range and genre. Similarly, detection results for other genres registered in advance are also stored in the memory 40a.

  When a genre or keyword is registered in the allocation button of the remote control device 50, the control unit 40 performs processing for detecting a program of the corresponding genre or a program including the keyword, and channel selection information used for channel selection of the detected program. Is stored in the memory 40a. For example, if a name (○ yama ○ mi) is registered as a keyword, at time “17:55”, as shown in FIG. 2, the name (○ yama ○ mi) that is a keyword is included only in channel CH-n3. Therefore, the channel selection information TU-n3 for selecting the program of the channel CH-n3 is stored in the memory 40a in association with the time range and the genre.

  Further, the control unit 40 performs the search process at intervals of 5 minutes as described above, and stores the detection result corresponding to the new time range “18: 00 ≦ Tj <18:05” in the memory 40a. For example, at time “18:00”, since a program belonging to the [News] genre is broadcast on channels CH-n2, CH-n4, CH-n5, and CH-n6, the control unit 40 selects this program. The channel selection information TU-n2, TU-n4, TU-n5, and TU-n6 for stationing is stored in association with the time range and the genre. Similarly, the control unit 40 stores channel selection information TU-n3 for selecting a program of the channel CH-n3 in association with the time range and the genre [variety], and stores the channels CH-n1, CH-n3. The channel selection information TU-n1 and TU-n3 for selecting the program is stored in association with the time range and the keyword. Further, the control unit 40 stores the detection result at the time “18:05” in association with the time range and the search condition.

  In addition, detection results in a time range that is earlier than the time range including the current time are not necessary for the channel selection operation, and are therefore deleted from the memory 40a to efficiently use the memory 40a. For example, within the range of time “18:00” to “18:05”, the search condition is satisfied from a program that starts broadcasting at time “18:10” and a program that is broadcasting at time “18:10”. When the program is detected, the detection result in the time range “17: 55 ≦ Tj <18:00” is unnecessary. Therefore, the search is performed after deleting the detection result of the time range “17: 55 ≦ Tj <18:00”, and the detection result of the obtained time range “18: 10 ≦ Tj <18:15” is stored in the memory 40a. Let For this reason, the stored detection results after the elapse of time are as shown in FIG.

  In this search process, if the time interval for repeating the search process is widened, the number of search processes can be reduced, so that the load on the control unit 40 can be prevented from increasing. However, when the time range becomes large, the ratio of the time range in which the program switching occurs within the range increases, and it becomes difficult to correctly present only the programs that satisfy the search condition. In addition, if the search time interval is narrowed and the time range is reduced, the proportion of the time range in which program switching occurs within the range decreases, so only programs that satisfy the search condition can be presented accurately. Is possible. However, since the number of searches increases, the load on the control unit 40 increases. Accordingly, the time interval and time range for searching are set in consideration of the processing capability of the control unit 40 and the ratio of the time range in which the program is switched.

  In this way, the control unit 40 stores the detection result in the memory 40a in advance, and assigns the program detected in the time range including the current time to the genre button and the allocation button. For example, when the current time Tj is included in the time range “17: 55 ≦ Tj <18:00”, if the detection result shown in FIG. 4 is stored in the memory 40a, the control unit 40 The channel selection information TU-n5 is assigned to the genre button 517a in which [News] is registered as a search condition. In addition, the control unit 40 assigns channel selection information TU-n3 and TU-n6 to the genre button 517b in which [Variety] is registered as a search condition, and the keyword (○ yama ○ good) is registered as a search condition. Channel selection information TU-n3 is allocated to the allocation button 518d.

  Thereafter, when the current time Tj is included in the time range “18: 00 ≦ Tj <18:05”, the control unit 40 is assigned, for example, [News] to the genre button 517a registered as a search condition. The channel selection information TU-n5 is updated to channel selection information TU-n2, TU-n4, TU-n5, and TU-n6. Information on other buttons is also updated.

  By the way, in the above-described case, the search process is performed at predetermined time intervals. However, a time zone with a high probability that a program will be switched (for example, a time zone in which the time is “0 minutes” or “30 minutes”). ), The time range may be narrowed, and the time range may be widened in a time zone where the probability of program switching is low. In this case, it is possible to efficiently perform the search process so that the switching of programs within the time range is reduced compared to the case where the search process is performed at regular time intervals.

  Further, the search process may be performed so that the program is not switched within the time range. In other words, based on the program information, the time at which the program is switched may be determined, and a program that satisfies the search condition may be detected from a program that starts broadcasting at this time or a program that is being broadcast. The detection result is stored in the memory 40a in association with a time range during which no program is switched.

  For example, when program switching is performed as shown in FIG. 2, for example, when a program that satisfies the search condition is detected from a program that starts broadcasting at time “18:15” or a program that is being broadcast, the detection result is displayed in the time range. It is stored in relation to “18: 15 ≦ Tj <18:30”. In addition, search processing is performed for the next program change time “18:30”, and programs that start broadcasting at the time “18:30” or programs that are broadcasting are detected. In this case, the detection result is stored in association with the time range “18: 30 ≦ Tj <19: 0”. Further, it is determined in which time range the current time is included, and a detection result corresponding to the determined time range is assigned to the operation button. Further, when the current time exceeds the determined time range, the program assigned to the operation button is updated by assigning a detection result corresponding to the newly included time range to the operation button. If such processing is performed, the detection result can correctly indicate a program that satisfies the search condition. Also in this case, it goes without saying that the search process is performed so that the detection result corresponding to this time range is stored in the memory 40a before the current time falls within the time range.

  Next, an operation when the signal corresponding to the operation of any of the genre buttons 517a to 517d or the allocation buttons 518a to 518d is supplied from the remote control device 50 to the control unit 40 will be described.

  When the operation signal PS based on the remote control signal is supplied, the control unit 40 determines which one of the genre buttons 517a to 517d or the allocation buttons 518a to 518d is operated. Next, the control unit 40 determines a program assigned to the determined button among the genre buttons 517a to 517d or the allocation buttons 518a to 518d. Further, the operation of the receiving unit 11 is controlled so as to select the determined program. Further, when there are a plurality of programs assigned to the determined button, each time this button is repeatedly operated, the assigned program is sequentially selected, and the receiving unit 11 selects the selected program. To control the operation.

  For example, when the current time Tj is in the time range “17: 55 ≦ Tj <18:00”, the genre button 517b in which the search condition [variety] is registered is used to select a channel CH-n3 program. Channel selection information TU-n3 and channel selection information TU-n6 for selecting a channel CH-n6 program are allocated. Therefore, when the genre button 517b is operated, the assigned channel selection information TU-n3 is supplied to the receiving unit 11 and the channel is designated to the receiving unit 11. For this reason, when the genre button 517b is operated, programs belonging to the [variety] genre broadcast on the channel CH-n3 can be presented quickly.

  When the same genre button 517b is repeatedly operated, the channel is designated using the next channel selection information TU-n6, thereby quickly switching to the program broadcast on the channel CH-n6 of the same genre. Can do.

  When the current time Tj is included in the time range “18: 00 ≦ Tj <18:05”, the program assigned to the genre button 517b is updated from two programs to one program. For this reason, when the genre button 517b is operated, a channel is designated based on the channel selection information TU-n3. However, since one program is assigned, even if the genre button 517b is repeatedly operated, the program of the channel designated based on the channel selection information TU-n3 is continuously presented. .

  If a program that satisfies the search condition is not assigned to the genre button or the allocation button, the control unit 40 controls the operation of the video output processing unit 123 when the button is operated, and the display device 13 If it is displayed on the screen that the corresponding program is not found, the viewer can easily grasp that the program satisfying the search condition is not broadcast.

  As described above, it is assumed that the program information is searched with the search condition registered in the operation button, and the program satisfying the search condition is assigned to the operation button in advance. Further, when the operation button is operated, a channel is designated using channel selection information for selecting an assigned program. For this reason, when viewing a program of a desired genre or a program having a desired keyword, it is not necessary to input a genre or keyword each time, and it is not necessary to perform a search after the operation button is operated. A desired program can be viewed quickly and easily, easily and easily. In addition, only by repeatedly operating the operation buttons, only programs of a desired genre and programs having a desired keyword can be quickly switched and presented.

  6 to 8 are flowcharts showing processing when the control unit 40 is configured using a computer and the above reception operation is performed by software.

  FIG. 6 is a flowchart showing an allocation process when registering a genre and a keyword for an allocation button. FIG. 6 shows processing when an operation button provided in the broadcast receiving device 10 or the remote control device 50 is operated and an assignment function for registering a genre or keyword is selected in the assignment buttons 518a to 518d. ing.

  In step ST1, the control unit 40 determines an allocation button for registering a genre and a keyword, and proceeds to step ST2. In the determination of the allocation button, the control unit 40 determines, for example, in the remote control device 50, the allocation button that is first operated after the start of the allocation processing operation is an allocation button for registering a genre and a keyword. Alternatively, a display for prompting selection of an allocation button may be displayed on the display device 13, and the allocation button operated when this display is performed may be determined as an allocation button for registering a genre or a keyword.

  In step ST2, the control unit 40 determines the search condition input by the viewer and proceeds to step ST3. Here, a search condition by the viewer, for example, input of a genre or a keyword, is performed using a keyboard or operation buttons of a remote control device. When using a keyboard, for example, a keyboard connection terminal is provided in the broadcast receiving apparatus 10, and a keyboard is connected to the keyboard connection terminal so that a viewer can operate it. A so-called software keyboard may be used as the keyboard. When the software keyboard is used, the control unit 40 displays characters, numbers, symbols, and the like on the screen of the display device 13, and displays the displayed characters, numbers, symbols, etc. by operating the buttons of the remote control device 50 or the input unit. Select one by one and confirm the search conditions. Furthermore, when inputting a genre, a keyword, or the like from the remote control device 50, characters and symbols are assigned in advance to the numeric button group 512 of the remote control device 50, and the assigned character is operated by operating the numeric button group 512. Select and input symbols and symbols sequentially. It should be noted that the input of genres and keywords by the user is not limited to the method described above, and it is needless to say that other methods may be used.

  The control unit 40 detects the operation of the keyboard and the remote control device 50 to determine the input genre and keyboard. In addition, in the input of genres and keywords, the control unit 40 is not limited to registering only one genre or keyword. As described above, a plurality of genres and keywords can be registered, and an AND search or an OR search is performed. It is good also as what enables it to be performed.

  In step ST3, the control unit 40 registers the search condition input in step ST2 in the allocation button determined in step ST1, and proceeds to step ST4.

  In step ST4, the control unit 40 determines whether or not to continue the allocation process. Here, when the allocation process is continued and an operation for registering the search condition in another allocation button is performed, the process returns to step ST1. Further, when the operation for ending the allocation process is performed, the process proceeds to step ST5.

  In step ST5, the control unit 40 acquires the current time and proceeds to step ST6. In step ST6, the control unit 40 performs a search process and proceeds to step ST7. In this search process, the control unit 40 searches for program information using the search conditions registered in the genre button and the allocation button, and detects programs that satisfy the search conditions. In this search process, not only a program at a time earlier than the current time but also a program at the current time is searched.

  In step ST7, the control unit 40 performs a storage process of the detection result and proceeds to step ST8. That is, the control unit 40 stores the program detected in step ST6 in the memory 40a in association with the time range and the search condition.

  In step ST8, the control unit 40 assigns the detected program. That is, based on the detection result stored in the memory 40a, the control unit 40 allocates a program that is being broadcast and a program that starts broadcasting to the genre button and the allocation button, and ends the allocation process. .

  FIG. 7 is a flowchart showing the detection result update process. This detection result update process is performed at predetermined time intervals so that when the user operates the genre button or the allocation button, a detection result corresponding to the time when the operation is performed can be obtained.

  In step ST11, the control unit 40 acquires the current time and proceeds to step ST12. In step ST12, the control unit 40 assigns a program that satisfies the search condition to the genre button and the allocation button based on the detection result of the time range corresponding to the current time, and proceeds to step ST13.

  In step ST13, the control unit 40 deletes unnecessary detection results, deletes detection results whose time range is older than the current time from the memory 40a, and proceeds to step ST14.

  In step ST14, the control unit 40 performs a search process and proceeds to step ST15. In this search process, the control unit 40 detects a program that satisfies the search condition registered in the genre button and the allocation button from programs that are being broadcast and started at a time earlier than the current time.

  In step ST15, the control unit 40 performs a storage process of the detection result. That is, the control unit 40 stores the program detected in the search process in step ST14 in the memory 40a in association with the time range and the search condition, and ends the detection result update process.

  FIG. 8 is a flowchart showing an operation when the operation button is operated.

  In step ST21, the control unit 40 determines whether or not the operation button is operated. When the operation button is not operated, the control unit 40 returns to step ST21, and when the operation button is operated, the process proceeds to step ST22. For example, the control unit 40 returns to step ST21 when the operation signal based on the remote control signal from the remote control device 50 is not supplied, and proceeds to step ST22 when the operation signal based on the remote control signal is supplied. .

  In step ST22, the control unit 40 determines whether the operated button is a genre button or an allocation button. Here, when determining that the operation of the genre button or the allocation button has been performed based on the operation signal, the control unit 40 proceeds to step ST23, and when determining that the operation of another button has been performed, the control unit 40 proceeds to step ST32.

  In step ST23, the control unit 40 determines whether or not the operated button has been registered for operation. Here, when the button is operated for the first time, the operation proceeds to step ST24, and the operation registration is performed. When the same button is operated repeatedly, the operation registration is performed, and the operation proceeds to step ST27.

  In step ST24, the control unit 40 performs operation registration as described above, sets the operated button to operation registered, and proceeds to step ST25.

  In step ST25, the control unit 40 initializes the variable m, sets “m = 1”, and proceeds to step ST26. This variable m indicates the order of programs to be designated from programs assigned to the genre button and the allocation button.

  In step ST26, the control unit 40 determines the number of programs KC assigned to the genre button or keyword button for which operation registration has been performed, and proceeds to step ST27.

  In step ST27, the control unit 40 determines whether or not the number of programs KC is “0”. When the program number KC is not “0”, the process proceeds to step ST28, and when the program number KC is “0”, the process proceeds to step ST33.

  In step ST28, the control unit 40 determines whether or not the value of the variable m is equal to or less than the number of programs KC. Here, when the value of the variable m is equal to or less than the number of programs KC, the process proceeds to step ST30. If the value of the variable m exceeds the number of programs KC, the process proceeds to step ST29.

  In step ST29, the control unit 40 initializes the variable m, sets “m = 1”, and proceeds to step ST30.

  In step ST30, the control unit 40 performs a channel selection operation based on the channel selection information so that the m-th program can be viewed, and proceeds to step ST31.

  In step ST31, the control unit 40 adds “1” to the variable m, newly sets the variable m, and returns to step ST21.

  In step ST22, when it is determined that the signal corresponds to the operation of another button and the process proceeds to step ST32, the control unit 40 performs a process corresponding to the operation of the other button and returns to step ST21. In Step ST27, when it is determined that the number of programs KC is “0” and the process proceeds to Step ST33, the control unit 40 displays that the corresponding program is not found and returns to Step ST21.

  In this way, even when viewing a program of a desired genre or a program having a desired keyword, software does not need to input a genre or keyword each time, and a search is performed after an operation button is operated. There is no need, and the desired program can be viewed quickly and easily, easily and easily. In addition, only by repeatedly operating the operation buttons, only programs of a desired genre and programs having a desired keyword can be quickly switched and presented.
