A corresponding instruction is determined and an instruction corresponding to the operation input of the key is received.

  FIG. 2 shows an example of a program guide display (image display displayed on the display) corresponding to the program guide data generated by the program guide generator.

  The program guide screen display 201 includes at least a channel display column 201A-201I (row direction), a time zone display column 201-10, and a date / time display column 201-11 for displaying programs broadcast by a predetermined number of channels (broadcast stations). .

  In the program guide screen display 201 shown in FIG. 2, the program A01 of the channel PM4: 00-PM5: 30 displayed in the channel display field 201A, the program C01 of the PM7: 30-PM9: 00 of the channel displayed by the same 201C, It is assumed that a recording reservation is registered in the program G01 of PM3: 00-PM4: 00 of the channel displayed by the 201G and the program H01 of PM6: 00-PM7: 30 of the channel displayed by the 201H. Further, as described above, the input unit (tuner unit) 11 is a three-wave tuner that can select one of the terrestrial / BS / CS digital broadcast programs for two channels (two tuners). (One tuner) is a two-wave tuner that can select any of BS / CS digital broadcast programs, and includes a total of three tuners. It is assumed that any one of the three-wave tuners receives the program H01 of PM 6:00 to PM 7:30 of the channel displayed in the channel display column 201H.

  Here, in order to preliminarily record the program D01 of PM5: 30-PM9: 00 of the channel displayed in the channel display column 201D of FIG. 2, when the remote control terminal 71 focuses the program display and instructs the recording reservation, As shown in FIG. 3, a duplicate reservation confirmation / cancellation screen display 301 is displayed. Note that the same program means, for example, a program ID (program information) included in PSI / SI, character information for EPG, for example, a code (symbol) indicating “new program”, a program title, and characters in the program description. It can be easily determined from one or more of various information already used such as a column or series number.

  The duplicate reservation confirmation / cancellation screen display 301 is displayed in a date / time display column 301-11, a new reserved program display column 301-21, duplicate reserved program display columns 301-31 and 301-32, and a new reserved program display column 301-21. A reservation change candidate display field 301-41 and a display field scroll button 301-51 when there is a broadcast of another date / channel of a program to be reserved for recording are displayed. The display example shown in FIG. 3 shows an example in which the same program as the program displayed in the new reserved program display field 301-21 is broadcast at another time, and the same program as the selected new reserved program is reserved and changed. It is an example displayed in the candidate display column 301-41.

  Each of the new reserved program display column 301-21, the duplicate reserved program display column 301-31, 301-32 and the reservation change candidate display column 301-41 is a selection input for selecting a program to be displayed in each column. It includes check boxes 301-21A, 301-31A, 301-32A and 301-41A to be received. The presence / absence of checks in the individual check boxes 301-21A, 301-31A, 301-32A, and 301-41A is preferably associated with each other. For example, it is assumed that the check box 301-21A of the new reserved program display column 301-21 is checked in order to delete the new reservation in order to eliminate the duplicate reservation. After that, when the check box 301-31A or 301-32A of the duplicate reserved program display fields 301-31 and 301-32 is checked, the check box 301-21A of the new reservation is to be released. Is preferred. Similarly, when the check box 301-21A of the reservation change candidate display column 301-41 is checked after the check box 301-21A of the new reserved program display column 301-21 is checked, the check box of the new reservation is displayed. It is preferable to associate with each other so that the check of 301-21A is released.

  The display column scroll button 301-51 is displayed when there are a plurality of reservation change candidate programs displayed in the reservation change candidate display column 301-41. When the scroll button 301-51 is turned on, as shown in FIG. 10, the reservation change candidate programs are sequentially displayed. Further, when there are a plurality of reservation change candidate programs and the scroll button 301-51 is turned on, it is possible to scroll in the reverse direction to display the reservation change candidate programs that are no longer displayed on the screen display 301. The scroll button 301-52 to be displayed is displayed.

  In the duplicate reservation confirmation / cancellation screen display 301 shown in FIG. 3, the next screen display is displayed based on whether the user changes the registration of a new reservation or restarts a new reservation.

  Note that the duplicate reservation confirmation / cancel screen display 301 shown in FIG. 3 is based on the premise that the already set recording reservation is not changed.

  For example, when the check box 301-21A in the new reserved program display field 301-21 is checked, as shown in FIG. 4, "" cancel new reservation "/" reserving recording reservation candidate as it is " "Please press [ENTER]" and a message 411 prompting the user to change the new reservation is displayed on the screen display 301 in a superimposed manner. Note that the [ENTER] instruction input may be, for example, an operation input from the remote control terminal 71 to the [ENTER] button displayed in the screen display 301, or a determination key on the remote control terminal 71 is turned on (pressed). May be. [Determination] instruction input can be performed by turning on (pressing) a color key of a color corresponding to the color of the button that defines the [Determination] instruction input in the screen display 301, for example, the [Red] key 71R. . In this case, the [OK] button displayed in the screen display 301 is assigned to, for example, the [Red] button display 26 </ b> R among the color button displays. Note that the [OK] button displayed on the screen display 301 is not necessarily limited to the “decision” display, and may be an arbitrary (specific) display that can specify the user's intention to input an operation.

  On the other hand, if none of the check boxes are checked, after a certain time (period) has elapsed, as shown in Fig. 5, the recording reservation such as "" To cancel the new reservation, press [Back] " A message 511 urging re-execution is displayed over the display content of the screen display 301. When a predetermined time, for example, 3 minutes elapses without the return key being turned on, it is preferable to stop accepting registration of a new reservation as a timeout process. In FIG. 5, “return” instruction input is performed by turning on (pressing) a color key of a color corresponding to the color of the button defining the “return” instruction input in the screen display 301, for example, the “yellow” key 71 Y. Can be input. In this case, the [Return] button displayed in the screen display 301 is assigned to, for example, the [Yellow] button display 26Y in the color button display. Note that the [Return] button displayed in the screen display 301 is not necessarily limited to the “return” display, and may be an arbitrary (specific) display that can specify the user's intention to input an operation.

  FIG. 6 shows, in terms of software, the registration change and redo determination shown in FIGS. 3 to 5.

  Based on the user instruction (recording reservation), the program guide is displayed [601].

  Recording reservation registration is activated based on an instruction for recording reservation of an arbitrary program displayed on the program guide screen display [602].

  Whether or not the program selected as a new recording reservation program from the program guide screen display can be recorded, that is, the number of recording reservation programs already registered does not reach the upper limit of the number of programs that can be recorded simultaneously (duplication [603]. When a new recording reservation program can be reserved [603-YES], the recording reservation of the selected program is registered [604].

  If a new recording reservation program cannot be reserved due to duplicate reservation [603-NO], a duplicate reservation confirmation / cancel screen display (FIG. 3) is displayed [605].

  In response to the displayed duplicate reservation confirmation / cancellation screen display, an instruction to delete a new reservation for canceling the duplicate reservation is given (in the duplicate reservation confirmation / cancellation screen display, a new reserved program is deleted or a reservation change candidate program is selected. If instructed [606-YES], the recording reservation is registered [604].

  In response to the displayed duplicate reservation confirmation / cancellation screen display, an instruction to delete a new reservation for canceling the duplicate reservation is given (in the duplicate reservation confirmation / cancellation screen display, a new reserved program is deleted or a reservation change candidate program is selected. [606-NO] when a predetermined time has elapsed [607-YES], a message ([Return]) prompting the user to redo the recording reservation is displayed [608].

  When the recording reservation is canceled in response to a message prompting the user to redo the recording reservation (redoing the recording reservation is selected) [609-YES], the program guide is displayed again [601].

  If there is no response to the message prompting to redo the recording reservation [609-NO], the recording reservation registration is terminated after a predetermined time has elapsed.

  FIG. 7 shows an example in which the recording reservation of the new reserved program is preferentially registered in the duplicate reservation confirmation / cancel screen display shown in FIG. That is, the duplicate reservation confirmation / cancellation screen display shown in FIG. 7 shows an example in which the same program as the program for which the recording reservation has already been registered is broadcast at another time in the reservation change candidate display field 701-41. . As a result, when a program to be newly reserved is not broadcasted at another time or another channel, and a program for which a recording reservation is already registered is broadcast at another time or another channel In addition, it is possible to make a recording reservation for both.

  In the duplicate reservation confirmation / cancellation screen display 701 shown in FIG. 7, the next screen display is displayed based on whether the user changes the registration of a new reservation or restarts a new reservation. For example, when the check box 301-21A in the new reserved program display column 701-21 is checked, as shown in FIG. 8, “The program of the new reserved program has not been confirmed for another time” / A new reservation change message 811 such as “If you want to make a recording reservation for an overlapping program that has already been reserved for recording, press the enter key” is displayed in an overlapping manner on the display content of the screen display 701. As a result, it is possible to prevent the recording (reserved recording) of a new reservation target program that cannot be specified to be broadcast at another time or channel.

  9 and 10 show examples of screen display when either or both of a newly reserved program and a duplicate reserved program are broadcast as a rebroadcast program in the duplicate reservation confirmation / cancellation screen display shown in FIG. . That is, the duplicate reservation confirmation / cancellation screen display shown in FIG. 9 is displayed in the reservation change candidate display field 901-41 when the program already registered for recording or the same program as the newly reserved program is rebroadcasted at another time. An example in the case of being broadcast at another time is shown. Thus, the user can select to delete the recording reservation of either the program that is about to be newly reserved or the program that is already reserved for recording. As shown in FIG. 9, when there are a plurality of the same programs or series programs broadcast at other times or other channels and cannot be displayed in one screen display, a display column scroll button 901 is displayed. -51 is displayed to notify that there is a program that is not displayed. In addition, as shown in FIG. 10, a scroll that enables scrolling in the reverse direction to display a reservation change candidate program that is no longer displayed on the screen display 901 when the display column scroll button 901-51 is turned on. Buttons 1001-52 are displayed. Thereby, all the change candidate programs can be confirmed by a user operation (instruction input).

  As shown in FIG. 10, when a program that is the same as a newly reserved program is broadcast as a rebroadcast program in a plurality of other time zones, it is broadcast in a time zone in which the number of programs that can be recorded simultaneously is large. It is preferable to display only a rebroadcast program. In addition, even if a duplicate reservation occurs and a rebroadcast program that is subject to a reservation change has been found, there is already a recording reservation for another program during that time period, and the maximum number of programs that can be recorded at the same time has been reached. If so, it is preferable not to display the rebroadcast program because it cannot be recorded. For example, if the number of programs that can be recorded at the same time is less than the number of programs received by the tuner unit, even if a rebroadcast program that is subject to a reservation change is found, the recording reservation for that time zone has already been made When there is a recording reservation for another program and the upper limit of the number of programs that can be recorded at the same time is reached, the rebroadcast program cannot be recorded. In other words, if duplicate reservations occur and the number of recording reservations has reached the maximum number of programs that can be recorded at the same time, even if a program subject to reservation change has been found, rebroadcast Even if it is a program, it is excluded from the target of reservation change and displayed.

  Note that a re-broadcast program that has only one re-broadcast as a candidate for reservation change has a re-broadcast, but it is displayed on the screen that the reservation cannot be changed due to a duplicate reservation of another recording reservation. Etc., the user may be notified.

  In addition, in the duplicate reservation confirmation / cancellation screen display 901 shown in FIG. 9, as shown in FIG. 11, "" Duplicate reservation has occurred "," Please cancel either new reservation or recording reservation "" It is preferable to display a reservation change recommendation message 1111 indicating that it is necessary to cancel the duplicate reservation, such that the display contents of the screen display 901 are overlapped.

  If the recording reservations are duplicated (the number of programs reserved for recording has reached the upper limit of the number of programs that can be recorded simultaneously), simply “the recording reservation has been duplicated (the upper limit of the number of programs that can be recorded simultaneously has been reached). It is also possible to display a message indicating that “new recording reservation” cannot be registered.

  In this way, by applying the embodiment, when the same program broadcast at another time or channel reaches the upper limit of the number of programs that can be simultaneously recorded at the time of recording reservation, By changing the recording reservation of one of the same programs broadcasted at other times or channels, it is possible to prevent the recording (reserved recording) from being lost. In addition, the number of programs that can be recorded at the same time as the recording reservation of a new reservation target program that cannot be specified to be broadcast at another time or channel overlaps with the recording reservation of the same program broadcast at another time or channel. When the upper limit is reached, it is possible to prevent a new recording (reserved recording) from being lost by changing the recording reservation of the same program broadcast at another time or channel.
