Description

  The present invention relates to a program recording apparatus and a program recording method for recording a program based on recording reservation information.

  Already, recorders for recording programs on DVDs or HDDs have become widespread. In addition, recorders that are equipped with multiple tuners and that can record multiple programs simultaneously have appeared. In recent years, digital television broadcast receivers capable of recording programs have also appeared. Such a digital television broadcast receiver records a program in a built-in HDD or an external HDD.

  The above-mentioned recorder outputs display information for displaying an EPG (electronic program guide), registers recording reservation information of the selected program in the recording reservation list in response to a user's recording program selection operation, and performs recording. Refer to the reservation list and perform recording. The digital television broadcast receiver described above displays an EPG, registers recording reservation information of the selected program in the recording reservation list in response to the user's recording program selection operation, and refers to the recording reservation list. Perform recording.

  In the above, reference has been made to the appearance of a recorder capable of overlapping recording. However, although it is possible to perform overlapping recording, the number of tuners mounted is limited, and therefore the number of programs capable of overlapping recording is also limited. For example, assume a recording device equipped with one tuner for terrestrial analog broadcasting and two tuners for digital terrestrial broadcasting. Such a recording device, for example, can simultaneously record up to two terrestrial digital broadcasts in the same time zone, and can also record a total of two programs, one terrestrial analog broadcast program and one terrestrial digital broadcast program in the same time zone. You can also record at the same time. However, such a recording device cannot simultaneously record up to two terrestrial analog broadcasts in the same time zone.

  The user must know the tuner configuration of the recording device, be aware of what programs can be recorded at the same time and what programs cannot be recorded at the same time, and users who are not familiar with the device will be confused There is also a possibility.

  In view of this, a technique for mapping registered reservation information and the number of available tuners and / or the number of overlapping reservations in each time zone based on the registered reservation information to EPG information is disclosed (see Patent Document 1). In addition, a technique for displaying a recording reservation bar indicating the presence or absence of a recording reservation on a recording bar display unit corresponding to each time according to the reservation status is disclosed (see Patent Document 2).

Japanese Patent Laying-Open No. 2007-110559 (see FIGS. 22 and 24) JP 2004-228849 A

  The techniques disclosed in Patent Documents 1 and 2 can relatively easily grasp the duplicate reservation status. However, when trying to add a recording reservation, it is difficult to know which recording reservation should be deleted when a recording reservation cannot be added due to over-limitation of the overlapping reservation. That is, when adding a recording reservation, if a recording reservation cannot be added due to over-limitation of overlapping reservations, it is not always possible to add a recording reservation just by deleting one recording reservation. Therefore, there are cases where multiple recording reservations must be deleted in order to add a recording reservation. In such a case, depending on the combination of recording reservations to be deleted, a recording reservation can be added or cannot be added. To do.

  An object of the present invention is to provide a program recording apparatus and a program recording method capable of supporting the deletion of a recording reservation when a duplicate reservation limit is exceeded due to the addition of a recording reservation.

  The program recording apparatus according to an embodiment of the present invention is designated by registration means for registering each recording reservation information relating to recording reservation of each program in the recording reservation list, and first recording reservation information registered in the recording reservation list. Extracting means for extracting, from the recording reservation list, recording reservation information that is on the same day as the recorded recording date and that overlaps at least a part of the recording time period specified by the first recording reservation information. A cancel candidate specifying means for specifying a cancel candidate for the duplicate recording reservation information, and a program corresponding to the first recording reservation information, assuming that the redundant recording reservation information specified as the cancellation candidate is cancelled. Outputs a first display information for displaying the first recording reservation information and the duplicate recording reservation information, and displays a determination result of the determination means. Display information output means for outputting second display information for canceling, cancellation execution specifying means for specifying execution of cancellation of the duplicate recording reservation information specified as the cancellation candidate, and based on the cancellation execution specification, Canceling means for canceling the duplicate recording reservation information designated as a cancellation candidate from the recording reservation list, and recording means for recording the program in the program storage unit with reference to the recording reservation information included in the recording reservation list. I have.

  The recording reservation management method according to an embodiment of the present invention registers each recording reservation information related to recording reservation of each program in the recording reservation list, and is designated by the first recording reservation information registered in the recording reservation list. Recording reservation information that is the same day as the recording date and that overlaps at least a part of the recording time zone specified by the first recording reservation information and the recording time zone is extracted from the recording reservation list, and Recording reservation information and first display information for displaying the overlapping recording reservation information, a cancel candidate is designated for the overlapping recording reservation information, and the overlapping recording reservation information specified as the cancellation candidate Assuming cancellation, it is determined whether or not the program corresponding to the first recording reservation information can be recorded, the second display information for displaying the determination result is output, and designated as the cancellation candidate Duplicate recording Specifies the execution of cancellation of about information, based on the cancellation execution specified, cancel the duplicated video recording reservation information specified in cancellation candidate from the recording reservation list.

The HDD recorder and the DVD recorder display display information for displaying the EPG and recording reservation information on the display unit. An information output unit is provided. By replacing the video display of the digital television broadcast receiving apparatus described below with a display information output unit, the recording reservation described in this embodiment can be applied to an HDD recorder and a DVD recorder.

  FIG. 1 shows a main signal processing system of the digital television broadcast receiving apparatus 100 described above. That is, the satellite digital television broadcast signal received by the BS / CS digital broadcast receiving antenna 47 is supplied to the satellite digital broadcast tuners 49a and 49b via the input terminal 48, thereby broadcasting the desired channel. A signal is selected. The digital television broadcast receiver 100 includes satellite digital broadcast tuners 49a and 49b, so that satellite digital broadcast signals of up to two channels can be simultaneously selected. In the present embodiment, the case where the digital television broadcast receiving apparatus 100 includes two satellite digital broadcast tuners will be described. However, the digital television broadcast receiver 100 may be configured to include three or more satellite digital broadcast tuners.

  The broadcast signals selected by the tuners 49a and 49b are supplied to PSK (phase shift keying) demodulation modules 50a and 50b, demodulated into digital video signals and audio signals, and then sent to the signal processing module 51. Is output.

  The terrestrial digital television broadcast signal received by the terrestrial broadcast receiving antenna 52 is supplied to the terrestrial digital broadcast tuners 54a and 54b via the input terminal 53, so that the broadcast signal of the desired channel can be obtained. To be selected. The digital television broadcast receiving apparatus 100 includes digital terrestrial broadcast tuners 54a and 54b, and can simultaneously select terrestrial digital broadcast signals of up to two channels. In the present embodiment, the case where the digital television broadcast receiving apparatus 100 includes two terrestrial digital broadcast tuners will be described. However, the digital television broadcast receiving apparatus 100 may be configured to include three or more terrestrial digital broadcast tuners.

  The broadcast signals selected by the tuners 54a and 54b are supplied to an OFDM (orthogonal frequency division multiplexing) demodulation module 55, demodulated into digital video signals and audio signals, and then sent to the signal processing module 51. Is output.

  The terrestrial analog television broadcast signal received by the terrestrial broadcast receiving antenna 52 is supplied to the terrestrial analog broadcast tuner 56 via the input terminal 53, so that the broadcast signal of the desired channel is selected. Bureau. The broadcast signal selected by the tuner 56 is supplied to the analog demodulation module 57, demodulated into an analog video signal and audio signal, and then output to the signal processing module 51.

  Here, the signal processing module 51 selectively performs predetermined digital signal processing on the digital video signal and audio signal supplied from the PSK demodulation module 50 and the OFDM demodulation module 55, respectively, and the graphic processing module 58. And output to the audio processing module 59.

  The signal processing module 51 is connected to a plurality (four in the illustrated case) of input terminals 60a, 60b, 60c, and 60d. These input terminals 60 a to 60 d can input analog video signals and audio signals from the outside of the digital television broadcast receiver 100.

  The signal processing module 51 selectively digitizes the analog video signal and audio signal supplied from the analog demodulation module 57 and the input terminals 60a to 60d, respectively, and the digitized video signal and audio signal. Are subjected to predetermined digital signal processing and then output to the graphic processing module 58 and the audio processing module 59.

  Among them, the graphic processing module 58 has a function of superimposing and outputting the OSD signal generated by the OSD (on screen display) signal generation module 61 on the digital video signal supplied from the signal processing module 51. The graphic processing module 58 selectively outputs the output video signal of the signal processing module 51 and the output OSD signal of the OSD signal generation module 61, and combines both outputs so as to constitute half of the screen. Can be output.

  The digital video signal output from the graphic processing module 58 is supplied to the video processing module 62. The video signal processed by the video processing module 62 is supplied to the video display 14 and is also supplied to the output terminal 63. The video display 14 displays video based on the video signal. When an external device is connected to the output terminal 63, the video signal supplied to the output terminal 63 is input to the external device.

  The audio processing module 59 converts the input digital audio signal into an analog audio signal in a format that can be reproduced by the speaker 15, and then outputs the analog audio signal to the speaker 15 for audio reproduction. Through the outside.

  Here, in the digital television receiver 100, all the operations including the above-described various reception operations are comprehensively controlled by the control module 65. The control module 65 includes a CPU (central processing unit) and the like, and receives operation information from the operation module 16 or operation information sent from the remote controller 17 and received via the light receiving module 18. Each module is controlled so that the operation content is reflected.

  In this case, the control module 65 mainly includes a read only memory (ROM) 66 that stores a control program executed by the CPU, a random access memory (RAM) 67 that provides a work area for the CPU, and various setting information. And a non-volatile memory 68 in which control information and the like are stored.

  Further, the control module 65 is connected to a card holder 70 in which the first memory card 19 can be mounted via a card I / F (interface) 69. Thereby, the control module 65 can perform information transmission via the card I / F 69 with the first memory card 19 attached to the card holder 70.

  The control module 65 is connected via a card I / F (interface) 71 to a card holder 72 in which the second memory card 20 can be mounted. Thereby, the control module 65 can perform information transmission with the second memory card 20 mounted in the card holder 72 via the card I / F 71.

  The control module 65 is connected to the LAN terminal 21 via the communication I / F 73. Thereby, the control module 65 can perform information transmission with the LAN compatible device connected to the LAN terminal 21 via the communication I / F 73. In this case, the control module 65 has a DHCP (dynamic host configuration protocol) server function, and performs control by assigning an IP (internet protocol) address to a LAN compatible device connected to the LAN terminal 21. An example of the LAN-compatible device is a NAS (Network Attached Storage) 103.

  Further, the control module 65 is connected to the first HDMI terminal 22 via the first HDMI I / F 74. Accordingly, the control module 65 can perform information transmission with the HDMI compatible device connected to the first HDMI terminal 22 via the first HDMI I / F 74. The control module 65 is connected to the second HDMI terminal 23 via the second HDMI I / F 75. Accordingly, the control module 65 can perform information transmission with the HDMI compatible device connected to the second HDMI terminal 23 via the second HDMI I / F 75.

  The control module 65 is connected to the USB terminal 24 via the USB I / F 76. As a result, the control module 65 can perform information transmission with the USB compatible device connected to the USB terminal 24 via the USB I / F 76. An example of the USB compatible device is the USB-HDD 102.

  Further, the control module 65 is connected to the i. I. Via Link I / F77 The link terminal 25 is connected. As a result, the control module 65 makes i. I. Connected to the Link terminal 25; A Link-compatible device; i. Information transmission can be performed via the Link I / F 77. i. Link compatible devices include i. A Link-HDD 104 is an example.

  Further, the control module 65 refers to each recording reservation information included in the recording reservation list stored in the nonvolatile memory 68 and controls the recording operation. As the recording destination, for example, the built-in HDD 101, USB-HDD 102, NAS 103, i. A LINK-HDD 104 is an example.

  The built-in HDD 101 and the USB-HDD 102 can support simultaneous recording of a maximum of n programs (n = 2 in this embodiment) due to the characteristics of the devices. It is defined as a program storage module. One NAS 103, i. The LINK-HDD 104 cannot handle simultaneous recording of up to n programs (cannot support simultaneous recording) due to the characteristics of the device, and can only record one program at a time. NAS103, i. The LINK-HDD 104 is defined as a second program storage module.

  Therefore, in order to record the program P1 and the program P2 simultaneously, it is necessary to combine the recording destination of the program P1 and the recording destination of the program P2 as follows.

1. Program P1 → Internal HDD 101 / Program P2 → Internal HDD 101
2. Program P1 → Internal HDD 101 / Program P2 → USB-HDD 102
3. Program P1 → USB-HDD 102 / Program P2 → USB-HDD 102
Next, an example of recording reservation based on the recording control of the control module 65 will be described. For example, a recording reservation based on the recording reservation information R1 and the recording reservation information R2 registered in the recording reservation list will be described. For example, the recording reservation information R1 includes information indicating that the program P1 of 9:00 to 10:00 on one channel of terrestrial digital broadcasting is recorded on the built-in HDD 101. Further, the recording reservation information R2 includes information indicating that the 9:00 to 10:00 program P2 of the three channels of digital terrestrial broadcasting is recorded on the built-in HDD 101.

  In this case, based on the recording control of the control module 65, the tuner 54a selects a broadcast signal of one channel of terrestrial digital broadcast before 9:00, and transmits a broadcast signal of one channel of terrestrial digital broadcast until at least 10:00. Continue to tune in. Further, based on the recording control of the control module 65, the tuner 54b selects a terrestrial digital broadcast 3 channel broadcast signal before 9:00 and selects a terrestrial digital broadcast 3 channel broadcast signal until at least 10:00. Continue to bureau. Thereby, the broadcast signal of the program P1 is input to the signal processing module 51 in the time zone of 9:00 to 10:00, and the broadcast signal of the program P2 is also input in the time zone of 9:00 to 10:00. . Based on the recording control of the control module 65, the signal processing module 51 starts a recording operation and supplies the broadcast signal of the program P1 in the time zone from 9:00 to 10:00 to the built-in HDD 101. The broadcast signal of the program P1 in the 10:00 time zone is recorded. Similarly, the signal processing module 51 supplies a broadcast signal of the program P2 in the time zone from 9:00 to 10:00 to the built-in HDD 101, and the built-in HDD 101 broadcasts the program P2 in the time zone from 9:00 to 10:00. Record the signal.

  As described above, both the program P1 and the program P2 can be recorded correctly if the condition for enabling duplicate recording is satisfied. However, if the condition for enabling duplicate recording is not satisfied, the program to be recorded cannot be recorded. In such a case, it is necessary to cancel one or a plurality of recording reservation information.

  Next, recording reservation with cancellation of recording reservation information will be described with reference to the flowchart of FIG.

  For example, the user who wants to make a recording reservation presses a program guide key provided in the remote controller 17 (ST11, YES). In response to this, the video processing module 62 outputs display information for displaying the program guide, and the video display 14 displays the program guide (ST13 or ST14).

  For example, if the recording reservation information is not registered in the recording reservation list (ST12, NO), as shown in FIG. 3, the program guide displays two lanes L1 and L2 for displaying the recording reservation bar. (Free lanes L1, L2). In this embodiment, in order to describe a digital television broadcast receiving apparatus capable of recording two programs simultaneously, the number of lanes is two. In the case of a digital television broadcast receiving apparatus capable of simultaneously recording three programs, the number of lanes is three.

  As shown in FIG. 3, when the program guide includes empty lanes L1 and L2, the user can record two programs simultaneously as a premise, and can reserve recording of two programs in the same time period. Can be easily known. In addition, a boundary is shown between the two lanes L1 and L2, so that the user can more clearly recognize that two programs can be simultaneously recorded in each time zone.

  When the user presses a cursor movement key (cross key) provided on the remote controller 17 with the program guide displayed on the video display, the cursor on the program guide moves. For example, when the user presses the enter key provided on the remote controller 17 with the cursor selecting the program B2, for example, a screen for selecting a viewing reservation or a recording reservation for the program B2 is displayed. Further, when the user uses the remote controller 17 to select a recording reservation, selects the internal HDD 101 as a recording device, and determines (ST15), the control module 65 adds the recording reservation information RB2 of the program B2 to the recording reservation list. Register (ST16).

  The control module 65 refers to the recording reservation list and determines whether or not there is a duplicate recording reservation (ST17). Here, it is assumed that it is determined whether or not there is a duplicate recording reservation that violates the duplicate recording enabling condition. An example of overlapping recording reservation that violates the overlapping recording enabling condition will be described later. If there is no overlapping recording reservation that violates the conditions for enabling overlapping recording, that is, there is no overlapping recording that cannot be recorded (ST18, NO), and the program guide key provided in the remote controller 17 is not pressed again (or the remote controller). 17 is not pressed) (ST29, YES), the display returns to the program guide display state (ST13).

  Again, with the program guide displayed on the video display, the user uses the cursor movement key and the enter key provided on the remote controller 17 to select the recording reservation for the program A3, and the built-in HDD 101 is used as a recording device. When selected and determined (ST15), the control module 65 registers the recording reservation information RA3 of the program A3 in the recording reservation list (ST16). Even in this case, there is no duplicate reservation that cannot be recorded (ST17) (ST18, NO), the video processing module 62 outputs display information for displaying the program guide, and the video display 14 displays, for example, a program as shown in FIG. A guide is displayed (ST13).

  As shown in FIG. 4, the program guide includes lanes L1 and L2, and the lane L1 includes recording reservation bars BB2 and BA3. As a result, the user can preliminarily record two programs, and can reserve recording of one program in the time zone of program B2 and program A3, and time other than the time zone of program B2 and program A3. It is easy to know that the recording of two programs can be reserved in the band. In addition, a recording check indicating that the recording is reserved is displayed in each column of the programs B2 and A3 in the program guide.

  Again, with the program guide displayed on the video display, the user uses the cursor movement key and the enter key provided on the remote controller 17 to select the recording reservation for the program B3, and the built-in HDD 101 is used as a recording device. When selected and determined (ST15), the control module 65 registers the recording reservation information RB3 of the program B3 in the recording reservation list (ST16). Even in this case, there is no duplicate reservation that cannot be recorded (ST17) (ST18, NO), the video processing module 62 outputs display information for displaying the program guide, and the video display 14 is, for example, as shown in FIG. A program guide is displayed (ST13).

  As shown in FIG. 5, the program guide includes lanes L1 and L2, lane L1 includes recording reservation bars BB2 and BA3, and lane L2 includes recording reservation bar BB3. As a result, the user can pre-record two programs at the same time, can no longer reserve further recording in the overlapping time zone of program A3 and program B3, and time other than the overlapping time zone of program A3 and program B3. It is easy to know that recording of one program or two programs can be reserved in the band. In addition, a recording check indicating that the recording is reserved is displayed in each column of the programs B2, A3, and B3 in the program guide.

  6, 7, and 8, recording reservation information RC <b> 3 for recording the program C <b> 3 on the internal HDD 101, recording reservation information RB <b> 2 for recording the program B <b> 2 on the NAS 103, and recording the program C <b> 6 on the USB-HDD 102. The figure which shows the example of a display of the program guide in the state by which recording reservation information RC6 which records recording reservation information RC6 which records program A3 with recording reservation information RC6, built-in HDD101, and program C9 with respect to USB-HDD102 was set. It is.

  The NAS 103 does not support simultaneous recording of two programs. Therefore, in response to the setting of the recording reservation information RB2, as shown in FIG. 6, the recording reservation bar BB2 is displayed in both the lanes L1 and L2. Alternatively, as shown in FIG. 7, the recording reservation bar BB2 may be displayed across the boundary between the lanes L1 and L2 (with the boundary removed). Alternatively, as shown in FIG. 8, the recording reservation bar BB2 may be displayed in the lane L1, and the toned down recording reservation bar BB2 'may be displayed in the lane L2. Thereby, the user can easily know that the recording reservation can no longer be set by setting the recording reservation information RB2. Note that a recording check indicating that the recording is reserved is displayed in each column of the programs B2, A3, C3, C6, and C9 in the program guide shown in FIGS.

  As shown in FIG. 6, the display color of the recording reservation bar may be changed. For example, the recording reservation bars BC3 and BA3 corresponding to the recording reservation information RC3 and RA3 including information with the internal HDD 101 as the recording destination are displayed in red. Further, the recording reservation bar BB2 corresponding to the recording reservation information RB2 including the information with the NAS 103 as the recording destination is displayed in blue. Further, the recording reservation bars BC3 and BA3 corresponding to the recording reservation information RC3 and RA3 including information with the USB-HDD 102 as the recording destination are displayed in green. Thereby, the user can recognize the difference in recording destination at a glance.

  Next, a process when there is a duplicate recording reservation that violates the duplicate recording enabling condition, that is, when there is a duplicate reservation that cannot be recorded will be described.

  Assume that the control module 65 registers recording reservation information RP1 corresponding to the recorded program P1 in the recording reservation list (ST16). For example, it is assumed that the recorded program P1 is a 9:00 to 11:00 program of 4 channels of terrestrial digital broadcasting. Further, it is assumed that the recording reservation information RP1 includes information for recording the recorded program P1 in the built-in HDD 100 (first program storage module). The control module 65 refers to the recording reservation list and determines whether or not the registration of the recording reservation information RP1 does not violate the condition for enabling duplicate recording (ST17). In the case of violation, that is, when the recorded program P1 cannot be recorded (ST18, YES), the control module 65 extracts one or a plurality of overlapping recording reservation information from the recording reservation list (ST19).

  For example, assume that duplicate recording reservation information RP2, RP3, RP4, and RP5 corresponding to the duplicate recording programs P2, P3, P4, and P5 are extracted. The overlap recording program P2 is assumed to be a program from 9:00 to 10:00 on 5 channels of satellite digital broadcasting. The overlap recording program P3 is assumed to be a 9:00 to 10:00 program of 6 channels of digital terrestrial broadcasting. The overlap recording program P4 is assumed to be a 10:00 to 11:00 program of 5 channels of satellite digital broadcasting. The overlap recording program P5 is assumed to be a 10:00 to 11:00 program of 6 channels of digital terrestrial broadcasting. Further, it is assumed that the recording reservation information RP2 includes information for recording the recorded program P2 to the USB-HDD 102 (first program storage module). It is assumed that the recording reservation information RP3 includes information for recording the recorded program P3 to the built-in HDD 100 (first program storage module). The recording reservation information RP4 is assumed to include information for recording the recorded program P4 to the USB-HDD 102 (first program storage module). The recording reservation information RP5 is assumed to include information for recording the recorded program P5 to the built-in HDD 100 (first program storage module).

  In other words, the above case requires simultaneous recording of three programs, which violates the condition for enabling duplicate recording (two programs can be recorded simultaneously).

  The video processing module 62 outputs display information for distinguishing and displaying the recording reservation information RP1 and the overlapping recording reservation information, and the video display 14 displays the recording reservation information RP1 and the overlapping recording reservation information as shown in FIG. Are displayed separately (ST20).

  When the user presses a cursor movement key provided on the remote controller 17 in a state where the duplicate reservation cancellation screen shown in FIG. 9 is displayed, the cursor on the screen moves. For example, when the user presses the determination key provided on the remote controller 17 with the cursor selecting the duplicate reservation cancellation check box CB1 (ST21, YES), the control module 65 cancels the duplicate reservation cancellation check box CB1. A check is set, and duplicate recording reservation information RP2 is designated as a cancellation candidate (ST22). If the user again presses the enter key provided in the remote controller 17 with the cursor selecting the duplicate reservation cancellation check box CB1 (ST21, YES), the control module 65 causes the duplicate reservation cancellation check box CB1. The cancellation check set to “2” is removed, and the duplicate recording reservation information RP2 is removed from the cancellation candidates (ST22).

  With respect to the duplicate reservation cancellation check boxes CB2, CB3, and CB4, the cancellation check can be set or the cancellation check can be removed by the same operation.

  Each time a cancellation candidate is designated, the control module 65 assumes cancellation of the duplicate recording reservation information designated as the cancellation candidate, and determines whether or not the recording program P1 corresponding to the recording reservation information RP1 can be recorded ( ST23). Similarly, every time the cancellation candidate is canceled, the control module 65 determines whether or not the recording program P1 corresponding to the recording reservation information RP1 can be recorded (ST23). Until the recorded program P1 can be recorded, the cancel execution icon in the screen of FIG. 9 is in a tone-down state (inactive state), and this cancel execution icon cannot be selected. Further, for each determination, the video processing module 62 outputs display information for displaying the determination result, and the video display 14 displays the determination result (ST24). As a result, the user can simulate the cancellation of the reservation and execute the cancellation work that satisfies the user's request when the duplicate recording enabling condition associated with the recording reservation addition is violated (when the overlapping reservation limit is exceeded). Can do.

  FIG. 10 is a diagram illustrating a screen display example in a case where it is assumed that the overlapping recording reservation designated as the cancellation candidate is canceled, the overlapping recording enabling condition is satisfied, and the recorded program P1 can be recorded. When the recorded program P1 can be recorded (ST25, NO) and the screen of FIG. 10 is displayed, the cancel execution icon in the screen of FIG. 10 is in a tone-up state (active state), and this cancel execution icon is selected. (ST26). Further, the cursor may be automatically moved to the cancel execution icon (ST26). When the user designates cancel execution using the determination key provided on the remote controller 17 (ST27, YES), the control module 65 cancels the overlapping recording reservation information designated as the cancel candidate (ST28).

  As a result, the duplicate recording enabling condition is satisfied, and the recording program P1 corresponding to the recording reservation information RP1 can be recorded.

  FIG. 11 is a diagram showing a relationship between the recording reservation bar BP1 corresponding to the recording program P1 and the recording reservation bars BP2, BP3, BP4, and BP5 corresponding to the overlapping recording programs P2, P3, P4, and P5. It can be seen that if the recording reservation bars BP2, BP3, BP4, and BP5 are already set and an attempt is made to set the recording reservation bar BP1, the condition for enabling duplicate recording is violated.

  Next, with reference to FIG. 12 to FIG. 14, guidance for the minimum number of cancellation candidates for enabling recording of the recorded program P <b> 1 will be described.

  FIG. 12 is a diagram showing a case where an attempt to set the recording reservation bar BP1 in a state where the recording reservation bars BP11, BP12, and BP13 are set, and violates the duplicate recording enabling condition (two programs can be recorded simultaneously). In this case, even if the recording reservation information RP11 corresponding to the recording reservation bar BP11 is canceled, the duplicate recording enabling condition is not satisfied. In this case, when the recording reservation information RP12 or RP13 corresponding to the recording reservation bar BP12 or BP13 is canceled, the duplicate recording enabling condition is satisfied with the minimum number of cancellations.

  Therefore, the control module 65 extracts the recording reservation information RP12 or RP13 corresponding to the recording reservation bar BP12 or BP13 corresponding to the minimum number of cancellation candidates, and recommends cancellation of the recording reservation information RP12 or RP13. For example, the video processing module 62 outputs display information for displaying a cancel recommendation icon for the recording reservation information RP12 and RP13, and the recording reservation information RP11, RP12, BP13 corresponding to the recording reservation bars BP11, BP12, and BP13. On the screen on which RP13 is displayed, a cancel recommendation icon is displayed for the recording reservation information RP12 and RP13. That is, the recording reservation information RP12 or RP13 corresponding to the minimum number of cancellation candidates and the recording reservation information RP11 not corresponding are displayed separately.

  For example, when the recording reservation information RP12 is designated as a cancellation candidate, the control module 65 re-extracts the minimum number of cancellation candidates, and the video processing module 62 updates the display information according to the re-extraction. In this case, a cancel recommendation icon is displayed for the recording reservation information RP11 and RP13. Alternatively, since either of the recording reservation information RP11 and RP13 is canceled, the duplicatable recording condition is satisfied, the cancel recommendation icon may not be displayed on either of the recording reservation information RP11 and RP13.

  FIG. 13 is a diagram showing a case in which, while the recording reservation bars BP21, BP22, BP23, and BP24 are set, an attempt is made to set the recording reservation bar BP1, and the duplicate recording enabling condition (two programs can be recorded simultaneously) is violated. is there. In this case, cancellation of the recording reservation information RP24 corresponding to the recording reservation bar BP24 is recommended. For example, the video processing module 62 outputs display information for displaying a cancel recommendation icon for the recording reservation information RP24, and the recording reservation information RP21, RP22, BP24 corresponding to the recording reservation bars BP21, BP22, BP23, and BP24. On the screen on which RP23 and RP24 are displayed, a cancel recommendation icon is displayed for the recording reservation information RP24. That is, the recording reservation information RP24 corresponding to the minimum number of cancellation candidates and the recording reservation information RP21, RP22, and RP23 that do not correspond are displayed separately.

  For example, when the recording reservation information RP21 in which no cancel recommendation icon is displayed is designated as a cancel candidate, the control module 65 re-extracts the minimum number of cancel candidates, and the video processing module 62 displays it according to the re-extraction. Update information. In this case, a cancel recommendation icon is displayed again for the recording reservation information RP24.

  FIG. 14 is a diagram showing a case in which, in a state where the recording reservation bars BP31, BP32, and BP33 are set, an attempt to set the recording reservation bar BP1 violates the duplicate recording enabling condition (two programs can be recorded simultaneously). In this case, two programs can be scheduled for simultaneous recording at a time other than 9:00 pm to 10:00 pm, 11:00 pm to 0:00 am, and 9:00 pm to 10:00 pm In the time zone from 9:00 pm to 10:00 pm when the first program storage module is designated as the recording destination, another program recording reservation can be made, and the first program storage module is designated as the recording destination. One more program recording reservation can be made even at 11:00 PM to 0:00 AM. However, no more program recording reservations can be made in the time zone from 9:00 pm to 10:00 pm when the second program storage module is designated as the recording destination. In this case, cancellation of the recording reservation information RP31 corresponding to the recording reservation bar BP31 is recommended. For example, the video processing module 62 outputs display information for displaying a cancel recommendation icon for the recording reservation information RP31, and the recording reservation information RP31, RP32, RP33 corresponding to the recording reservation bars BP31, BP32, BP33 is displayed. On the displayed screen, a cancel recommendation icon is displayed for the recording reservation information RP31. That is, the recording reservation information RP31 corresponding to the minimum number of cancellation candidates and the recording reservation information RP32 and RP33 not corresponding are displayed separately.

  For example, when the recording reservation information RP32 in which the cancel recommendation icon is not displayed is designated as a cancel candidate, the control module 65 re-extracts the minimum number of cancel candidates, and the video processing module 62 displays it according to the re-extraction. Update information. In this case, a cancel recommendation icon is displayed again for the recording reservation information RP31.

  As described above, the user can efficiently cancel the reservation when the duplicate recording enabling condition associated with the recording reservation addition is violated (when the overlapping reservation limit is exceeded).

  The control module 65 selects a signal from a target broadcast station by the tuners 49a, 49b, 54a, 54b, 56 based on the recording reservation information registered in the recording reservation list by the recording reservation shown in FIG. USB-HDD 102, NAS 103, i. The target program is recorded on the LINK-HDD 104.

  The module described above may be realized by hardware, or may be realized by software using a CPU or the like.
