Description

  The present invention relates to a status notification device, and is suitable for application to, for example, a television receiver provided in a program recording system for recording a terrestrial digital television broadcast program.

  A conventional television receiver acquires electronic program guide information (EPG: Electronic Program Guide) transmitted from a broadcasting station and displays it on a monitor. When this is called a reserved program) to make a recording reservation, and when electronic program guide information is acquired again and displayed on the monitor, the reserved program identification information is added to the electronic program guide information and the reserved program is selected. I was checking.

In addition, the television receiver stores reservation information of reserved programs, and when there is a reserved program with overlapping broadcast hours, the reservation information is listed on the monitor together with identification information corresponding to the priority of the recording reservation. The reserved program to be preferentially recorded by displaying is notified (for example, refer to Patent Document 1).
JP 2003-37791 A (page 4, page 5, FIG. 9, FIG. 12)

  However, a television receiver having such a configuration notifies the user only of information related to a reserved program such as a reserved program to be preferentially recorded among reserved programs with overlapping broadcast hours and broadcast dates and times of reserved programs. Recording of the reserved program by the recording device fails because the recording device, such as a hard disk recorder that records the reserved program, does not notify even if the recording program cannot record the reserved program. There was a problem that there was a case.

  The present invention has been made in consideration of the above points, and an object of the present invention is to propose a state notification device that can remarkably reduce the failure of recording a reserved program by a recording device.

  In order to solve such a problem, in the present invention, it is determined whether or not a recording device that records a reserved program that has been reserved for recording in advance is in a state incapable of recording with respect to the recording of the reserved program. When it is determined that the recording is impossible, a status notification indicator indicating the recording impossible state is displayed on the display means.

  Accordingly, if the recording device is in a state incapable of recording with respect to the recording of the reserved program, the user is notified of the recording incapable state by the state notification indicator, and the recording incapable state of the recording device is recorded in the reserved program. It can be improved to a recordable state before starting.

  According to the present invention, it is determined whether or not a recording device that records a reserved program that has been reserved for recording in advance is in a state incapable of recording with respect to the recording of the reserved program, and the recording device is in an unrecordable state. If it is determined, the status notification indicator indicating the recording impossible state is displayed on the display means, thereby notifying the user of the recording impossible state with respect to recording of the reserved program of the recording device by the status notification indicator, The recording disabled state of the recording device can be improved to a recording ready state before starting the recording of the reserved program, and thus the failure of recording the reserved program by the recording device can be greatly reduced.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a program recording system to which the present invention is applied as a whole, and a television receiver 2 can be removably loaded with a memory stick (registered trademark) 3 so that the television receiver can be inserted. A memory stick 3 is used to record programs (hereinafter referred to as “reserved programs”) that have been reserved for recording in advance among various programs obtained by receiving the television signal from the antenna 2 for receiving the digital terrestrial television broadcast. It can be used as a recording device for recording.

  The program recording system 1 also records a reserved program using a hard disk by a hard disk recorder 6 connected to the television receiver 2 via a serial bus 5 conforming to the IEEE (Institute of Electrical and Electronics Engineers) 1394 standard. It can be used as a recording device.

  As shown in FIG. 2, the television receiver 2 includes various programs such as a recording device state notification program stored in advance in a ROM (Random Access Memory) 11 by an internal central processing unit (CPU) 20. Is expanded on a RAM (Random Access Memory) 12 and various commands transmitted as an infrared signal from a remote controller (not shown) are fetched via the infrared light receiver 14 to control the entire television receiver 2 in an integrated manner. As a result, various processes are executed.

  As a result, when a program viewing channel is selected via the remote controller during program viewing, the central processing unit 10 selects a television signal S1 of a plurality of channels received by the antenna 4 at the front end 15. A predetermined reception process is performed on the television signal S1 of the selected channel to generate a digital transport stream TS1.

  Further, the central processing unit 10 temporarily stores the transport stream TS1 in the buffer memory 17 in the demultiplexer 16, and uses, for example, a descrambling key read from an IC (Integrated Circuit) card (not shown). The descrambling process is performed, and the video packet data D1 and the audio packet data D2 are separated from the obtained program viewing transport stream.

  The central processing unit 10 decodes the video packet data D1 in the video decoder 18 and sends the obtained analog video signal S2 to the display unit 20 to display the program video. Data D2 is decoded, and the obtained analog audio signal S3 is sent to the speaker 21 to output program audio, thereby allowing the user to view a desired program.

  When the central processing unit 10 is requested to display the electronic program guide information via the remote controller when viewing the program, the demultiplexer 16 descrambles the transport stream TS1 fetched from the front end 15 at this time. The video packet data D1 and the audio packet data D2 are separated from the obtained program viewing transport stream, and packet data (hereinafter referred to as EPG packet data) D3 in which electronic program guide information is stored is also obtained. The EPG packet data D3 is once fetched from the demultiplexer 16 and sent to the video decoder 18.

  Then, the central processing unit 10 generates a video signal S2 corresponding to the video packet data D1 in the video decoder 18, decodes the EPG packet data D3, and synthesizes the obtained analog EPG signal with the video signal S2. Thus, the electronic program guide information is superimposed and displayed on the program video by sending it to the display unit 20, thus displaying the electronic program guide information of the channel selected for program viewing.

  In this state, when the reserved program is selected from the electronic program guide information via the remote controller, the central processing unit 10 takes in the program information corresponding to the reserved program in the electronic program guide information from the video decoder 18.

  At this time, the central processing unit 10 causes a recording device to be used for recording a reserved program among recording devices of the television receiver 2 and the hard disk recorder 6 to be selected via a remote controller.

  As a result, the central processing unit 10 generates reservation information storing the program information fetched from the video decoder 18 and the recording device information indicating the recording device selected to be used for recording the reserved program. By storing the information in the storage unit 23, the reserved program is reserved for recording in advance for the television receiver 2 and the hard disk recorder 6.

  In this way, the central processing unit 10 generates the reserved program transport stream TS2 from the television signal at the front end 15 based on the reservation information at the broadcast start time of the reserved program after recording the reserved program for recording. At the same time, the demultiplexer 16 applies descrambling processing to the transport stream TS2, thereby generating a program recording transport stream TS3.

  When the television receiver 2 is selected for recording the reserved program, the central processing unit 10 sends the program recording transport stream TS3 from the demultiplexer 16 to the memory stick interface unit 24, and the memory stick interface. By recording the program recording transport stream TS3 in a non-volatile memory (not shown) in the memory stick 3 in the unit 24, the reserved program (hereinafter referred to as “recorded program”) that has been reserved for recording to the television receiver 2 is recorded. This is called a receiver reserved program).

  When the hard disk recorder 6 is selected for recording the reserved program, the central processing unit 10 sends the program recording transport stream TS3 from the demultiplexer 16 via the IEEE interface unit 26 and the serial bus 5 sequentially. Send to.

  In the hard disk recorder 6, various programs stored in advance in the hard disk of the hard disk drive 31 by the internal control unit 30 are expanded on the RAM 32 and various processes are executed. The hard disk recorder 6 is transmitted from the television receiver 2. A reserved program (hereinafter referred to as a recorder reserved program) that has been reserved for recording on the hard disk recorder 6 by capturing the recorded transport stream TS3 via the IEEE interface unit 33 and recording it on the hard disk. record.

  On the other hand, the central processing unit 10 stores the nonvolatile data in the memory stick 3 via the memory stick interface unit 24 when a receiver reserved program recorded by the television receiver 2 is selected via the remote controller during program playback. The program recording transport stream TS3 is read from the memory and taken into the demultiplexer 16.

  When the recorder reserved program recorded by the hard disk recorder 6 is selected via the remote controller, the central processing unit 10 transmits the program recording transport stream TS3 reproduced from the hard disk of the hard disk drive 31 by the hard disk recorder 6 to the serial bus. 5 and the IEEE interface unit 26 are sequentially taken into the demultiplexer 16.

  As a result, the central processing unit 10 separates the video packet data D5 and the audio packet data D6 from the program recording transport stream TS3 in the demultiplexer 16 in the same manner as the above-mentioned program viewing, and also in the video decoder 18 and the audio decoder 19 The video packet data D5 and the audio packet data D6 are decoded, and the receiver-reserved program and recorder-reserved program thus recorded are viewed through the display unit 20 and the speaker 21.

  In addition to this configuration, in the case of this television receiver 2, when the central processing unit 10 activates the television receiver 2 in response to an activation command input via the remote controller, the recording device state read from the ROM 11 According to the notification program, the recording device state notification processing procedure RT1 shown in FIG. 3 is executed.

  When the central processing unit 10 executes the recording device state notification processing procedure RT1, the central processing unit 10 reserves recording reservation of the receiver reserved program for the television receiver 2 and recording reservation of the recorder reserved program for the hard disk recorder 6 in step SP1. If it is determined whether or not, and a negative result is obtained, the process proceeds to step SP2 to determine whether or not the television receiver 2 is reserved for recording only for the television receiver 2, and when a negative result is obtained again, In step SP3, it is determined whether or not the recording reservation program for the hard disk recorder 6 is reserved only for the hard disk recorder 6, so that both the television receiver 2 and the hard disk recorder 6 receive the receiver reservation program and the recorder reservation. If the program is not reserved for recording, the processing of steps SP1-SP2-SP3 is repeated cyclically. Waits for the recording reservation of the machine reserved program and recorder reserved program.

  If an affirmative result is obtained at step SP1, this indicates that the television receiver 2 is reserved for recording the television reserved program and the hard disk recorder 6 is reserved for recording the recorder reserved program. At this time, the central processing unit 10 proceeds to step SP4 to execute the receiver state determination process of the first subroutine SRT1 shown in FIG. 4, and moves to step SP5 to the recorder of the second subroutine SRT2 shown in FIG. A state determination process is executed.

  If an affirmative result is obtained in step SP2, this means that only the television receiver 2 has made a recording reservation for the receiver reserved program. At this time, the central processing unit 10 moves to step SP4. Only the first subroutine SRT1 is executed.

  Further, when a positive result is obtained in step SP3, this indicates that the recording reservation program of the recorder reserved program is reserved only for the hard disk recorder 6. At this time, the central processing unit 10 moves to step SP5 and performs the second processing. Only the subroutine SRT2 is executed.

  Here, first, the central processing unit 10 detects whether or not the memory stick 3 is loaded in the television receiver 2 via the memory stick interface unit 24 every time the memory stick 3 is inserted into and removed from the television receiver 2. .

  Further, the central processing unit 10 is provided with an erroneous erasure prevention switch that can be slid at the additional recording permission position and the additional recording prohibition position on the exterior surface of the memory stick 3, and the erroneous erasure prevention switch is slid to the additional recording prohibition position. Then, every time the memory stick 3 is loaded in the television receiver 2 by setting to prohibit additional recording and preventing erroneous erasure due to overwriting of data, the memory stick interface unit 24, the slide position of the erroneous erasure prevention switch of the memory stick 3 is detected.

  Further, the central processing unit 10 stores the memory stick every time the memory stick 3 is loaded into the television receiver 2 and every time the program recording transport stream TS3 is recorded and deleted from the nonvolatile memory in the memory stick 3. An empty area of the nonvolatile memory is detected as the remaining recordable time for the receiver reserved program via the interface unit 24.

  Accordingly, when the central processing unit 10 (FIG. 4) executes the receiver state determination process of the first subroutine SRT1, based on the detection result of whether or not the memory stick 3 is loaded in the television receiver 2 in step SP40. It is determined whether or not the memory stick 3 is loaded in the television receiver 2.

  If an affirmative result is obtained in this step SP40, this means that although the memory stick 3 is loaded in the television receiver 2, the program recording transport stream TS3 is recorded in the nonvolatile memory in the memory stick 3. In this case, the television receiver 2 can record the reserved program and the non-recordable state in which the receiver reserved program cannot be recorded. In this case, the central processing unit 10 proceeds to step SP41.

  In step SP41, the central processing unit 10 determines whether or not the memory stick 3 is set to permit additional recording based on the detection result of the slide position of the erroneous erasure prevention switch with respect to the memory stick 3.

  If an affirmative result is obtained in this step SP41, this means that the television receiver 2 is loaded with the memory stick 3 set to permit additional recording of the program recording transport stream TS3. There may be a shortage of empty space for recording the program recording transport stream TS3 in the non-volatile memory in the memory stick 3, and the television receiver 2 is still in a recordable state or a non-recordable state. This means that it is difficult to determine whether or not there is, and at this time, the central processing unit 10 proceeds to the following step SP42.

  In step SP42, the central processing unit 10 detects the empty area (that is, the remaining recordable time for the receiver reserved program) in the nonvolatile memory in the memory stick 3, and the individual receiver reserved programs to be broadcast in the future. Based on the broadcast time, it is determined whether or not there is an empty area in which the program recording transport stream TS3 of all the receiver reserved programs to be broadcast in the future can be recorded in the nonvolatile memory.

  If an affirmative result is obtained in step SP42, this means that the television 2 is loaded with the memory stick 3 set to allow additional recording of the program recording transport stream TS3. In the non-volatile memory, there is an empty area in which the program recording transport stream TS3 of all the receiver reserved programs can be recorded, so that all the receiver reserved programs to be broadcast in the future will be provided in the television receiver 2. Can be recorded. At this time, the central processing unit 10 proceeds to step SP43.

  Thereby, in step SP43, the central processing unit 10 determines that the television receiver 2 is in a recordable state capable of recording all the receiver reserved programs to be broadcast in the future, and proceeds to step SP44.

  On the other hand, if a negative result is obtained in step SP40, this means that the television receiver 2 is not loaded with the memory stick 3 that is the recording destination of the program recording transport stream TS3. This means that the television receiver 2 cannot record all of the receiver reserved programs that will be broadcast in the future if the memory stick 3 is not dealt with by the central processing unit 10 at this time. The process proceeds to step SP45.

  Accordingly, in step SP45, the central processing unit 10 records all the reserved program broadcasts in the future by recording the television receiver 2 unloaded with the memory stick 3 (hereinafter referred to as “memory unloaded”). After determining that the recording is impossible, the process proceeds to step SP44.

  If a negative result is obtained in step SP41, this means that the television set 2 is loaded with the memory stick 3 set to prohibit additional recording of the program recording transport stream TS3. If the user does not take any action to allow additional recording of the memory stick 3, the television receiver 2 cannot record all the reserved program broadcasts in the future. The central processing unit 10 moves to step SP46.

  In step SP46, the central processing unit 10 determines whether or not there is an empty area that can record the program recording transport stream TS3 of all receiver reserved programs to be broadcast in the nonvolatile memory in the same manner as in step SP42 described above. Judging.

  If a positive result is obtained in step SP46, this means that the television receiver 2 is loaded with the memory stick 3 set to prohibit the additional recording of the program recording transport stream TS3. This indicates that there is an empty area in which the program recording transport stream TS3 of all the receiver reserved programs can be recorded in the non-volatile memory. At this time, the central processing unit 10 proceeds to step SP47.

  In step SP47, the central processing unit 10 only sets the television receiver 2 for all receiver reserved programs to be broadcast in the future only by prohibiting the additional recording of the memory stick 3 (hereinafter referred to as the additional recording prohibiting setting). After determining that the recording is impossible, the process proceeds to step SP44.

  If a negative result is obtained in step SP46, even if this is dealt with by the user so as to allow additional recording of the memory stick 3, the memory stick 3 is replaced with a new one in accordance with this, or non-volatile. If it is not possible to secure the empty area by selecting and erasing the program recording transport stream TS3 to be erased from the memory, the television receiver 2 will broadcast the program scheduled to be recorded in the future. In this case, the central processing unit 10 at step SP48 indicates that it is impossible to record from the receiver reserved program at the head or after the head because there is not enough free space in the nonvolatile memory. Move.

  In step SP48, the central processing unit 10 discriminates that the television receiver 2 is in an unrecordable state with respect to the recording of all the receiver reserved programs to be broadcast in the future by setting the additional recording prohibition. The TV receiver 2 is not available in the non-volatile memory from the broadcast start time of the TV set reserved program that cannot be recorded due to the non-volatile area in the non-volatile memory being insufficient for the sequential recording of the reserved program. (Hereinafter, this is called memory shortage shortage), but after determining that the recording is impossible, the process proceeds to step SP44.

  Further, if a negative result is obtained in step SP42, this means that although the memory stick 3 set to permit additional recording of the program recording transport stream TS3 to the television receiver 2 is loaded, Unless the memory stick 3 is replaced with a new one, or the program recording transport stream TS3 to be erased is selected from the non-volatile memory and erased, it is not possible to secure an empty area. In the John receiver 2, it indicates that the empty area of the non-volatile memory cannot be recorded from the receiver reserved program at the head or after the head in accordance with the broadcast order of the receiver reserved program. At this time, the central processing unit 10 proceeds to step SP49.

  Accordingly, in step SP49, the central processing unit 10 is in a recordable state in which the television receiver 2 can record the receiver reserved program while the receiver reserved program can be recorded without running out of the non-volatile memory. It is determined that the television receiver 2 cannot record the receiver reserved program due to the lack of the memory empty area from the broadcast start time of the receiver reserved program that cannot be recorded due to insufficient empty area of the nonvolatile memory. It is determined that the recording is impossible, and the process proceeds to step SP44.

  When the central processing unit 10 determines in step SP44 that the television receiver 2 is in a recordable state for the recording of all the receiver reserved programs to be broadcast in the future, the reservation of the receiver reserved program in the storage unit 23 is performed. After storing recordable information indicating a recordable state in all information (hereinafter, specifically referred to as receiver reservation information) and updating the contents of the receiver reservation information, the process exits from the first subroutine SRT1. Move to SP6 (FIG. 3).

  Further, when the central processing unit 10 determines that the television receiver 2 is in an unrecordable state with respect to recording of all or some of the receiver reserved programs, the central processing unit 10 does not record all of the receiver reservation information in the storage unit 23 or the recording failure. The receiver reservation information of the receiver reserved program that is broadcast after the broadcast start time determined as the ready state is determined as the unrecordable information indicating the unrecordable state instead of the recordable information and the unrecordable state. Information on the reason for determination that memory is not loaded, additional recording prohibition setting and memory space shortage specified at the time (hereinafter referred to as receiver state determination reason information) is stored, and the contents of the receiver reservation information are stored. After the update, the process leaves the first subroutine SRT1 and proceeds to step SP6.

  Further, when the central processing unit 10 determines that the television receiver 2 has shifted from the non-recordable state to the recordable state, the central processing unit 10 can record from the non-recordable state in the receiver reservation information in the storage unit 23. After updating the contents of the receiver reservation information by storing recordable information in the receiver reservation information of the receiver reserved program to be recorded in the state, instead of the recordable information and the receiver state determination reason information The process leaves the first subroutine SRT1 and proceeds to step SP6.

  On the other hand, each time a device is connected to the television receiver 2 via the serial bus 5, the central processing unit 10 detects the presence or absence of connection of the device via the IEEE interface unit 26, and via the serial bus 5. When the device is connected, the device requests the device for identification information unique to the device via the IEEE interface unit 26, and the identification information obtained as a result is stored in the storage unit 23 in advance. It is detected whether the device connected to the television receiver 2 is the hard disk recorder 6 or not.

  When the hard disk recorder 6 is connected to the television receiver 2 via the serial bus 5, the central processing unit 10 periodically checks the communication state with the hard disk recorder 6 via the IEEE interface unit 26. The communication process is executed to detect whether a communication error has occurred.

  Further, the central processing unit 10 records and erases the program recording transport stream TS3 each time the hard disk recorder 6 is connected to the television receiver 2 via the serial bus 5 and to the hard disk of the hard disk recorder 6. Every time, an empty area of the hard disk is detected as the remaining recordable time for the reserved program of the recorder via the IEEE interface unit 26.

  Therefore, when the central processing unit 10 (FIG. 5) executes the recorder state determination process of the second subroutine SRT2, in step SP50, the detection result of the presence / absence of connection of the device to the television receiver 2 and the television receiver 2 concerned. It is determined whether or not the hard disk recorder 6 is connected to the television receiver 2 based on the detection result of whether or not the device connected to is the hard disk recorder 6.

  If an affirmative result is obtained in step SP50, this means that although the hard disk recorder 6 is connected to the television receiver 2 via the serial bus 5, the program recording transport stream TS3 is connected to the hard disk of the hard disk recorder 6. In this case, the hard disk recorder 6 can record the reserved recorder program and the unrecordable state cannot record the reserved recorder program. In this case, the central processing unit 10 proceeds to step SP51.

  In step SP51, the central processing unit 10 determines whether or not the hard disk recorder 6 can be satisfactorily communicated based on the detection result of the presence / absence of a communication error.

  If a positive result is obtained in step SP51, this means that there is no failure of the hard disk recorder 6 or damage to the serial bus 5, but the television receiver 2 and the hard disk recorder 6 can communicate well through the serial bus 5. In some cases, the hard disk recorder 6 may have insufficient free space for recording the program recording transport stream TS3 on the hard disk, and whether the hard disk recorder 6 is still in a recordable state or in a recordable state. This means that it is difficult to discriminate. At this time, the central processing unit 10 proceeds to the subsequent step SP52.

  In step SP52, the central processing unit 10 determines that all future broadcasts to the hard disk based on the detection result of the empty area for the hard disk (that is, the remaining recording time for the recorder reserved program) and the broadcast time of the recorder reserved program. It is determined whether or not there is an empty area where the program recording transport stream TS3 of the recorder reserved program can be recorded.

  If an affirmative result is obtained in this step SP52, this means that it is possible to communicate well with the hard disk recorder 6 connected to the television receiver 2 via the serial bus 5, and all the recorders are connected to the hard disk. This indicates that the presence of an empty area in which the program recording transport stream TS3 of the reserved program can be recorded allows the hard disk recorder 6 to record all the recorder reserved programs to be broadcast in the future. When this happens, the central processing unit 10 proceeds to step SP53.

  As a result, in step SP53, the central processing unit 10 determines that the hard disk recorder 6 is in a recordable state with respect to recording of all recorder reserved programs to be broadcast in the future, and proceeds to step SP54.

  On the other hand, if a negative result is obtained in step SP50, this means that no device is connected to the television receiver 2 including the hard disk recorder 6 which is the recording destination of the program recording transport stream TS3. Or, instead of the hard disk recorder 6, another device such as a DVD (Digital Versatile Disc) player, which is different from the recording device, is connected, and if the user does not cope with connecting the hard disk recorder 6 as it is, This indicates that the hard disk recorder 6 cannot record all the reserved recorder programs to be broadcast in the future. At this time, the central processing unit 10 proceeds to step SP55.

  In step SP55, when no device is connected to the television receiver 2, the central processing unit 10 does not connect the hard disk recorder 6 to the television receiver 6 (hereinafter referred to as “recorder unconnected”). It is determined that the recording of all the recorder reserved programs to be broadcast is impossible.

  On the other hand, when another device is connected to the television receiver 2 in place of the hard disk recorder 6, the central processing unit 10 replaces the hard disk recorder 6 with another device (hereinafter referred to as device replacement). ), It is determined that the recording of all recorder reserved programs to be broadcast in the future is impossible, and the process proceeds to step SP54.

  If a negative result is obtained in step SP51, this means that a communication error occurs between the television receiver 2 and the hard disk recorder 6 due to a failure of the hard disk recorder 6 or a damage of the serial bus 5, and the hard disk recorder 6 Since the transport stream TS3 for recording a program cannot be transmitted normally, if the user does not take measures to repair the hard disk recorder 6 or replace the serial bus 5 as it is, all data to be broadcast in the hard disk recorder 6 in the future. This means that the recorder reserved program cannot be recorded. At this time, the central processing unit 10 proceeds to step SP56.

  At step SP56, the central processing unit 10 determines that the hard disk recorder 6 is in an unrecordable state with respect to recording of all the reserved recorder programs to be broadcast in the future due to a communication error occurring with the television receiver 2. Thereafter, the process proceeds to step SP54.

  Furthermore, if a negative result is obtained in step SP52, this must be dealt with so that the user can select a program recording transport stream TS3 to be erased from the hard disk and erase it to ensure that an empty area is secured. In the hard disk recorder 6, it is indicated that the free area of the hard disk cannot be recorded from any of the recorder reserved programs at the head or after the head in accordance with the broadcast order of the recorder reserved programs in the future. The central processing unit 10 moves to step SP57.

  In step SP57, the central processing unit 10 determines that the hard disk recorder 6 is in a recordable state while the recorder reserved program can be recorded without running out of free space on the hard disk, and sequentially executes recording of the recorder reserved program. From the broadcast start time of the reserved recorder program that cannot be recorded due to insufficient hard disk space, the hard disk recorder 6 cannot be recorded due to insufficient hard disk space (hereinafter referred to as insufficient disk space). After determining the state, the process proceeds to step SP54.

  In step SP54, when the central processing unit 10 determines that the hard disk recorder 6 is in a recordable state with respect to recording of all the recorder reserved programs to be broadcast in the future, reservation information (hereinafter referred to as “recorder reserved program reservation information” in the storage unit 23). After this recordable information is stored in all of them and the contents of the recorder reservation information are updated, the process leaves the second subroutine SRT2 and proceeds to step SP6 (FIG. 3).

  Further, when the central processing unit 10 determines that the hard disk recorder 6 is in an unrecordable state with respect to recording of all or some of the recorder reserved programs, the central processing unit 10 determines that all of the recorder reservation information in the storage unit 23 is in an unrecordable state. Recorder reservation information of a reserved program that is broadcast after the broadcast start time is replaced with recordable information, information that is not recordable, memory not specified when it is determined that the recording is impossible, device replacement, addition After storing the recording prohibition setting and the information on the reason for determination that the memory space is insufficient (hereinafter referred to as “recorder state determination reason information”) and updating the contents of the recorder reservation information, the process leaves the second subroutine SRT2. To step SP6.

  In addition, when the central processing unit 10 determines that the hard disk recorder 6 has shifted from the unrecordable state to the recordable state, the central processing unit 10 records in the recordable state from the unrecordable state in the recorder reservation information in the storage unit 23. From the second subroutine SRT2 after storing the recordable information in the recorder reservation information of the recorder reserved program to be recorded instead of the recordable information and the recorder state determination reason information and updating the contents of the recorder reservation information. Exit from step SP6.

  In step SP6, the central processing unit 10 determines whether or not the user has requested display of a reservation list screen including a list of receiver reservation information and recorder reservation information via a remote controller, and obtains a negative result. By returning to step SP1 and repeating the processing of steps SP1-SP2-SP3-SP4-SP5-SP6 cyclically, recording reservations for the television receiver 2 and the hard disk recorder 6 are sequentially received, and the television receiver is also received. 2 and the hard disk recorder 6 wait for a reservation list screen display request while determining whether or not the recording is impossible.

  If an affirmative result is obtained in step SP6, this means that the user looks at the reservation list screen and the recording reservation status of the receiver reserved program and the recorder reserved program for the television receiver 2 and the hard disk recorder 6, and the television image receiving The central processing unit 10 moves to step SP7. At this time, the central processing unit 10 moves to step SP7.
