(Embodiment 1)
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. FIG. 1 is a block diagram showing the configuration of the recording apparatus 1 according to the present invention and the relationship between the recording apparatus 1 and the program providing apparatus 2.

  A recording apparatus 1 according to the present invention is connected to a program providing apparatus 2 via the Internet. The program providing device 2 stores program information such as program name by channel, program broadcast date, program broadcast start time, program broadcast end time, program category, performers, etc., and a database (DB) storing programs broadcast in the past. For example, a service provider or broadcasting station of CATV (Community Antenna Television or Cable Television) or VOD.

  The recording apparatus 1 demodulates a signal sent from the antenna 3 and converts it into a transport stream, a transport decode unit 5 that extracts necessary data from the transport stream from the tuner unit 4, and a program image And an image / audio decoding unit 6 for decoding audio data, and an interface (I / F) 7 for connecting to the display unit 15 and the speaker 16.

  In addition, the recording device 1 responds to instructions from the storage unit 8 that stores the content data of the program acquired from the program providing device 2, a reception unit 9 that receives instructions such as display of an electronic program guide, and a control unit 10 described later. An Internet connection device 12 for connecting to the Internet, a recording unit 13 for recording a program on a recording medium, an OSD processing unit 11 for displaying an electronic program guide or the like on the display unit 15 in response to an instruction from the control unit 10, and a timing device 14 And.

  The control unit 10 includes a CPU 101, a ROM 102, and a RAM 103. The ROM 102 stores in advance processing programs, character data to be displayed on the display unit 15, and the like. The RAM 103 stores, for example, received program information, a change history of register values in the image / sound decoding unit 6, and reservation recording information such as a broadcast date, a broadcast start time, and a broadcast end time of a program to be reserved.

  The CPU 101 determines whether or not the scheduled recording by the recording unit 13 is normal, searches the program information for data relating to the rebroadcast of the program, and determines whether or not the rebroadcast recording is normal as will be described later. The content data of the program is acquired from the program providing apparatus 2 via the Internet.

  Note that the CPU 101 determines whether or not the acquired program information includes data relating to the broadcast change of the program to be reserved and recorded, and whether or not the content data of the program to be reserved and recorded can be acquired from the program providing apparatus 2. Determine whether or not.

  The tuner unit 4 detects and demodulates a signal (RF signal) sent from the antenna 3, performs error correction, converts the signal into a transport stream, and sends the transport stream to the transport decoding unit 5.

  The transport decoding unit 5 takes out the image and audio data necessary for program reproduction from the transport stream sent from the tuner unit 4 and the data related to the electronic program guide, and converts the image and audio data into the image / audio decoding unit 6. Then, data related to the electronic program guide is sent to the control unit 10.

  The image / audio decoding unit 6 decodes the image and audio data sent from the transport decoding unit 5 and converts them into image and audio data that can be output by the display unit 15 and the speaker 16. However, when a power failure occurs, the image and sound data are interrupted, or an error is included in the image and sound data, the image and sound are disturbed. In such a case, the register value changes. Therefore, such a change history of the register value is recorded and, for example, the number of times the register value has risen to a predetermined value or more is counted, and if that is the predetermined number or more, the CPU 101 determines that the reservation recording is abnormal. I can do it.

  The storage unit 8 is composed of an optical disk or a magnetic disk, and temporarily stores image data and audio data of a program to be recorded by the recording unit 13 and stores content data of a program to be recorded for reservation acquired from the program providing apparatus 2.

  The accepting unit 9 is a remote operation device that remotely operates the recording device 1, for example, and accepts an electronic program guide display instruction, a program reservation recording instruction, and the like.

  The recording unit 13 records a program to be reserved and recorded on a recording medium such as a DVD or a magnetic tape in accordance with an instruction from the CPU 101.

  The OSD processing unit 11 generates image data based on character data, color data, and the like from the CPU 101, and displays the image data on the display unit 15 as an OSD signal. The OSD processing unit 11 can display an electronic program guide, a notification to the user, and the like.

  2 and 3 are flowcharts showing the control procedure of the CPU 101 of the recording apparatus according to Embodiment 1 of the present invention.

  The CPU 101 acquires program information including an electronic program guide via the antenna 3 or the Internet (S101) and stores it in the RAM 103. When the CPU 101 receives an electronic program guide display instruction from the user (S102), the CPU 101 reads out data related to the electronic program guide from the RAM 103 and sends the data to the OSD processing unit 11. The OSD processing unit 11 displays the electronic program guide on the display unit 15. . FIG. 4 is an exemplary diagram showing an example of an electronic program guide. In the electronic program guide, each channel logo, each channel number, a number registered in the receiving unit 9 of the channel, a program title for each channel, and the like are displayed. In the first embodiment, an “English course” program indicated by hatching in the figure will be described as an example. The “English lecture” program is broadcast for the first time at 8 o'clock on 12 channels, and the second time (rebroadcast) is broadcast on the BS channel at 11:55 on the same day.

  When the user receives a reservation recording instruction for a program by selecting a program (English course) that the user wants to record from the electronic program guide (S103), the CPU 101 uses the program information to determine the first broadcast of the program. Reservation record information such as broadcast channel, broadcast date, broadcast start time, broadcast end time, etc. is extracted and stored in the RAM 103 (S104).

  Next, the CPU 101 instructs the timing device 14 to start timing (S105). Thereafter, the CPU 101 determines whether or not a predetermined time has elapsed since the start of timing (S106). If the CPU 101 determines that a predetermined time has elapsed (S106: YES), it instructs the Internet connection device 12 to connect to the Internet (S111), and accesses the program providing device 2 via the Internet. The CPU 101 obtains the latest program information from the program providing device 2 (S112), and the reservation recording information of the program to be reserved and stored in the RAM 103 is compared with the latest program information to perform the reservation recording. It is determined whether there is a broadcast change of the program (S113). When the CPU 101 determines that there is no broadcast change of the program to be reserved and recorded (S113: NO), the CPU 101 returns to S105. On the other hand, if it is determined that there is a broadcast change of the program to be reserved and recorded (S113: YES), the reservation record information of the program to be reserved and recorded is changed based on the latest program information (S114), and then S105. Return to.

  On the other hand, if the CPU 101 determines that the predetermined time has not elapsed (S106: NO), it determines whether it is the broadcast start time of the program to be reserved and recorded (S107). When it is determined that it is not the broadcast start time of the program to be reserved and recorded (S107: NO), the process returns to S106. When the CPU 101 determines that it is the broadcast start time of the program to be reserved and recorded (S107: YES), it instructs the tuner unit 4 to detect the channel related to the program to be reserved and recorded, and the storage unit 8 13 instructs to temporarily store the image data and audio data of the program to be recorded (S108), and instructs the timing device 14 to end timing.

  As described above, the RAM 103 stores the change history of the register value of the image / audio decoding unit 6 when decoding the image data and audio data of the program to be reserved and recorded. After the temporary storage of the image data and audio data of the program to be recorded in the storage unit 8 is finished, the CPU 101 determines whether the reservation recording is normal based on the change history of the register value stored in the RAM 103. Is determined (S109). If the CPU 101 determines that the scheduled recording is normal (S109: YES), the CPU 101 instructs the recording unit 13 to record based on the image data and audio data temporarily stored in the storage unit 8 (S110).

  If the CPU 101 determines that the scheduled recording is abnormal or has failed due to a power failure or the like (S109: NO), the program in which the scheduled recording is abnormal from the program information stored in the RAM 103 (hereinafter referred to as a scheduled recording abnormal program). ) Is searched for data related to the rebroadcast (S115). In the case of rebroadcasting, especially in the case of rebroadcasting on other channels, because the title of the program is marked with “rebroadcast”, etc., it is difficult to search for data related to rebroadcasting using only the program title as a keyword Can occur. Therefore, in searching for data related to the rebroadcast of a reserved recording abnormal program, it is effective to search using the program category, performers, etc. as keywords in addition to the program title.

  The CPU 101 changes reservation recording information of the reservation recording abnormal program based on the searched data relating to rebroadcasting (S116), and instructs the timing device 14 to start timing. The CPU 101 instructs the storage unit 8 to temporarily store the image data and audio data of the re-broadcast of the reserved recording abnormal program at the start time of the re-broadcast of the reserved recording abnormal program (S117), and the timing device 14 ends the time measurement. Instruct. Next, after the temporary storage of the re-broadcast image data and audio data of the reserved recording abnormal program in the storage unit 8 is completed, the CPU 101 stores the change history of the register value related to the re-broadcasting of the reserved recording abnormal program from the RAM 103. Based on the change history, it is determined whether or not the rebroadcast recording of the reserved recording abnormal program is normal (S118). When the CPU 101 determines that the rebroadcast recording is normal (S118: YES), it is based on the rebroadcast image data and audio data of the reserved recording abnormal program temporarily stored in the storage unit 8 in the recording unit 13. Recording is instructed (S119).

  On the other hand, if the CPU 101 determines that the rebroadcast recording of the reserved recording abnormal program is abnormal (S118: NO), it instructs the Internet connection device 12 to connect to the Internet (S120), and the program is transmitted via the Internet. The providing device 2 is accessed. Next, the CPU 101 determines whether or not the content data of the program whose rebroadcast recording is abnormal (hereinafter referred to as a rebroadcast recording abnormal program) can be acquired (for example, downloaded) from the program providing apparatus 2. (S121). Specifically, it is determined whether or not there is a title of the rebroadcast recording abnormal program in the title list of the program broadcast in the past provided by the program providing apparatus 2.

  When the CPU 101 determines that the content data of the rebroadcast recording abnormal program can be acquired from the program providing apparatus 2 (S121: YES), the CPU 101 acquires the content data (S122) and stores it in the storage unit 8. Further, the recording unit 13 is instructed to perform recording based on the content data stored in the storage unit 8. On the other hand, when the CPU 101 determines that the content data of the rebroadcast recording abnormal program cannot be acquired from the program providing apparatus 2 (S121: NO), the character data stored in advance in the ROM 102 is read and the OSD processing unit is read out. 11 is displayed on the display unit 15 to notify that the content data of the rebroadcast recording abnormal program from the program providing apparatus 2 could not be acquired (S123).

  In Embodiment 1, although the example which alert | reports that to the user when acquisition of the content data of the program from the program provision apparatus 2 failed was demonstrated, it does not restrict to this. For example, if acquisition of program content data from the program providing device 2 fails, any of the image data and audio data related to the reservation recording and rebroadcast recording temporarily stored in the storage unit 8 is selected. The CPU 101 may instruct the recording unit 13 to perform recording based on image data and audio data with the smallest change in the register value.

(Embodiment 2)
The recording apparatus according to the second embodiment of the present invention is connected to the program providing apparatus via the Internet as in the first embodiment, and the program providing apparatus stores program information and programs broadcast in the past. For example, it is a CATV or VOD service provider or broadcasting station that includes a database (DB).

  The recording apparatus demodulates a signal sent from the antenna and converts it into a transport stream, a transport decoding unit that extracts necessary data from the transport stream from the tuner unit, and decoding of program image and audio data And an image / sound decoding unit for converting to an image and an interface for connecting to a display unit and a speaker.

  In addition, a storage unit that stores content data acquired from the program providing device, a reception unit that receives instructions such as display of an electronic program guide, an Internet connection device that connects to the Internet according to instructions from the control unit, and a recording medium A recording unit for recording a program, an OSD processing unit for displaying an electronic program guide or the like on a display unit according to an instruction from the control unit, and a timing device are provided.

  5 and 6 are flowcharts showing the control procedure of the CPU of the recording apparatus according to Embodiment 2 of the present invention.

  The CPU acquires program information including an electronic program guide via an antenna or the Internet (S201) and stores it in the RAM. When the CPU receives an electronic program guide display instruction from the user (S202), the CPU reads data related to the electronic program guide from the RAM and sends it to the OSD processing section, which displays the electronic program guide on the display section. FIG. 7 is a view showing an example of an electronic program guide with a part thereof omitted. In the electronic program guide, each channel logo, each channel number, a number registered in the reception unit of the channel, a program title for each channel, and the like are displayed. In the second embodiment, an “English course” program indicated by hatching in the figure will be described as an example. The “English lecture” program is broadcast for the first time at 8 o'clock on 12 channels, and the second time (rebroadcast) is broadcast on the BS channel at 11:55 on the same day. In addition, the third broadcast will be performed on 12 channels at 23:40 on the same day.

  When the user receives a program reservation recording instruction by selecting a program (English course) that the user wants to record from the electronic program guide (S203), the CPU determines from the program information to all broadcast dates of the program. Such data is extracted and stored in the RAM as reservation recording information (S204). FIG. 8 is an exemplary diagram showing an example of reservation record information. Reservation record information such as broadcast channel, broadcast date, broadcast start time, broadcast end time in the first to third broadcasts of the program is stored for each N, which is a variable indicating the order of reservation recording. The program to be reserved and recorded is the third broadcast last, and the maximum value of N is 3. The CPU stores in the RAM that the maximum value of N is 3.

  Next, the CPU substitutes 1 for N (S205), and instructs the storage unit to perform temporary storage based on the reservation record information related to the execution order N (S206). At the broadcast start time of the reserved recording information related to the execution order 1, the storage unit starts temporary recording of the program to be reserved recorded.

  When the storage unit temporarily records image data and audio data of a program to be reserved and recorded, a change history of register values in the image / audio decoding unit is stored in the RAM. After the temporary recording of the image data and audio data of the program in the storage unit is completed, the CPU determines whether the reserved recording is normal based on the change history stored in the RAM (S207). When the CPU determines that the reserved recording is normal (S207: YES), the CPU instructs the recording unit to perform recording based on the image data and audio data temporarily stored in the storage unit (S208).

  When the CPU determines that the reservation recording is abnormal or recording failure due to a power failure or the like (S207: NO), N + 1 is substituted for N (S209), and the obtained N and the maximum value of N read from the RAM are calculated. To determine whether the obtained N is larger than the maximum value of N (S210).

  When the CPU determines that the obtained N is not larger than the maximum value of N (S210: NO), the CPU returns to S206, and S206, S207, S209, and S210 are repeated. Among them, when the CPU determines that the reservation recording of the program to be reserved recording is normal (S207: YES), the process proceeds to S208, but the reservation recording based on the reservation recording information related to the maximum execution order N is also performed. When it is determined that there is an abnormality (S207: NO), it is determined in S210 that N obtained in S209 is larger than the maximum value of N, and the process proceeds to S211.

  If the CPU determines that the obtained N is greater than the maximum value of N (S210: YES), the CPU instructs the Internet connection device to connect to the Internet (S211), and accesses the program providing device via the Internet. Next, the CPU determines whether or not the content data of the program whose reservation recording is abnormal (hereinafter referred to as a reservation recording abnormal program) can be acquired (for example, downloaded) from the program providing apparatus (S212). . Specifically, it is determined whether or not there is a title of a reservation recording abnormal program in the title list of a program broadcast in the past provided by the program providing apparatus.

  When the CPU determines that the content data of the reserved recording abnormal program can be acquired from the program providing device (S212: YES), the CPU acquires the content data (S213) and stores it in the storage unit. Further, the recording unit is instructed to perform recording based on the content data stored in the storage unit. On the other hand, when the CPU determines that the content data of the reserved recording abnormal program cannot be acquired from the program providing apparatus (S212: NO), the character data stored in advance in the ROM is read and sent to the OSD processing unit. Is displayed on the display unit to notify the user that the content data of the reserved recording abnormal program from the program providing apparatus could not be acquired (S214).

  In the second embodiment, an example has been described in which, when acquisition of content data of a program from a program providing apparatus fails, the user is notified of that, but the present invention is not limited to this. For example, when acquisition of content data of a program from a program providing device fails, any of image data and audio data based on reservation recording information related to the execution order N temporarily stored in the storage unit is selected. The CPU may instruct the recording unit to perform recording based on image data and audio data with the smallest change in the register value.

  In Embodiments 1 and 2, a television program having image data and audio data has been described as an example. However, the present invention is not limited to this, and it goes without saying that the present invention can also be applied to a radio program having no image data. .

  In the first and second embodiments, the case of acquiring program information and program content data has been described with respect to connection with a program providing apparatus via the Internet. However, the present invention is not limited to this. For example, an optical cable, a radio wave, etc. May be used directly.
