  In the above firmware update system, automatic firmware update is performed only when automatic update is set to be permitted. However, in a conventional broadcast recording apparatus such as an HDD recorder, a program reserved for recording is displayed. In order to reliably record, if there is a program that is reserved for recording, automatic firmware update is prohibited. In other words, the firmware is updated to prevent a program reserved for recording from being recorded for some reason (for example, due to deletion of recording reservation information).

  However, there are cases where the user desires to update the firmware at an early stage, and the conventional broadcast recording apparatus may not be sufficiently convenient in updating the firmware.

  The present invention has been made in view of the above problems, and an object thereof is to provide a broadcast recording apparatus capable of updating firmware with good convenience.

  4 and 5 are flowcharts showing an example of the operation of the HDD recorder 1 (mainly the MPU 11). Here, for convenience, the recording reservation information is stored in advance in the recording reservation storage unit 121 by the recording reservation setting unit 111 and the conditions for updating the firmware are set by the first setting unit 112 and the second setting unit 113. Will be described.

  First, the transmission determination unit 114 determines whether or not the setting for updating the firmware has been performed (S101). When it is determined that the setting for updating the firmware has not been performed (= the first condition display unit 401a in FIG. 3 is selected and set) (NO in S101), the process is in a standby state. Is done. It is determined that the setting for updating the firmware is performed (= the second condition display unit 401b, the third condition display unit 401c, or the fourth condition display unit 401d in FIG. 3 is selected and set). In the case (YES in S101), the transmission determination unit 114 determines whether the firmware is transmitted (S103). If it is determined that the firmware is not transmitted (NO in S103), the process returns to step S101, and the processes after step S101 are repeatedly executed.

  If it is determined that the firmware is transmitted (YES in S103), the transmission determination unit 114 acquires the manufacturer ID information and the device model ID included in the SDTT via the reception unit 15 (S105). Then, the transmission determination unit 114 determines whether the manufacturer ID information and the device model ID acquired in step S105 match the manufacturer ID information and the device model ID information of the HDD recorder 1 (S107). ). If it is determined that they do not match (NO in S107), the process returns to step S101, and the processes after step S101 are repeatedly executed.

  If it is determined that they match (NO in S107), the date and time acquisition unit 115 acquires the start date and time information included in the SDTT via the reception unit 15 (S109). Then, the date / time determination unit 116 determines whether or not the start date / time (= transmission date / time) acquired in step S109 has been reached (S111). If it is determined that the transmission date / time has not been reached (NO in S111), the process is set to a standby state. If it is determined that the transmission date / time has been reached (YES in S111), as shown in FIG. 5, the update execution unit 118 sets that no update is performed when there is a program reserved for recording. It is determined whether or not it is present (S113). When there is a program reserved for recording, it is determined that the setting for not performing the update is not performed (= the third condition display unit 401c or the fourth condition display unit 401d in FIG. 3 is selected and set). If so (NO in S113), the process proceeds to step S117.

  When it is determined that updating is not performed when there is a program reserved for recording (= the second condition display unit 401b in FIG. 3 is selected and set) (YES in S113) ), The recording reservation determination unit 117 determines whether there is a program reserved for recording (S115). If it is determined that there is a program reserved for recording (YES in S115), the process returns to step S101 shown in FIG. 4, and the processes after step S101 are repeatedly executed. If it is determined that there is no program reserved for recording (NO in S115), the process proceeds to step S121.

  If NO in step S113 (= when the third condition display unit 401c or the fourth condition display unit 401d in FIG. 3 is selected and set), the update execution unit 118 makes a recording reservation for the PPV program. If so, it is determined whether or not the setting is made to not execute the update (S117). When the recording reservation of the PPV program is made, it is determined that the update is not performed (= the fourth condition display unit 401d in FIG. 3 is selected and set) (S117). NO), the process proceeds to step S121.

  When it is determined that the update is not executed when the recording reservation of the PPV program is set (= the third condition display unit 401c in FIG. 3 is selected and set) (S117) In YES, the recording reservation determination unit 117 determines whether or not the PPV program is reserved for recording (S119). If it is determined that the PPV program is reserved for recording (YES in S119), the process returns to step S101 shown in FIG. 4, and the processes after step S101 are repeatedly executed. If it is determined that the PPV program is not reserved for recording (NO in S119), the process proceeds to step S121.

  In the case of NO in step S115, in the case of NO in step S117, or in the case of NO in step S119, the firmware to be updated is acquired (= downloaded) via the receiving unit 15 by the update execution unit 118 (S121). ) Update is executed (S123), and the process is terminated.

  In this manner, an operation input from the user is received via the remote controller 3, and whether or not to update the firmware is set based on the received operation input, and a setting to update the firmware is set. If it is performed, it is determined whether or not firmware to be updated is transmitted based on the television broadcast received via the receiving unit 15.

Only when the firmware to be updated is acquired via the receiving unit 15 and the update is executed, if the user desires to execute the update even if there is a program reserved for recording. ,Recording reservation The update can be executed by setting the update to be executed when there is a program that is being updated (= selecting and setting the fourth condition display unit 401d in FIG. 3). The firmware can be updated.

  In addition, an operation input from the user is received via the remote controller 3, and based on the received operation input, it is set whether or not to perform an update when the program reserved for recording is a PPV program, It is determined whether the program reserved for recording is a PPV program. If it is a PPV program and the setting for executing the update is set (= when the fourth condition display section 401d in FIG. 3 is selected and set), it is assumed that the transmission date and time has been reached. When the determination is made, the firmware to be updated is acquired through the receiving unit 15 and the update is executed, and when it is a PPV program, the setting is made so as not to execute the update (= third in FIG. 3) If the condition display unit 401c is selected and set), it is determined that the transmission date / time has been reached, and it is determined that there is no program reserved for recording, or a program reserved for recording. Only when it is determined that the program is not a PPV program, the firmware to be updated is acquired through the receiving unit 15 and the update is executed. Therefore, the firmware can be updated more conveniently.

  In other words, if it is set to execute the update in the case of a PPV program (= when the fourth condition display unit 401d in FIG. 3 is selected and set), it is assumed that the transmission date and time has been reached. When the determination is made, the firmware to be updated is acquired through the receiving unit 15 and the update is executed, and when it is a PPV program, the setting is made so as not to execute the update (= third in FIG. 3) If the condition display unit 401c is selected and set), it is determined that the transmission date / time has been reached, and it is determined that there is no program reserved for recording, or a program reserved for recording. Only when it is determined that the program is not a PPV program, the firmware to be updated is acquired via the receiving unit 15 and the update is executed. Therefore, when the program reserved for recording is a PPV program so However, if it is desired to execute the update, the update is performed by setting the update to be performed for the PPV program (= selecting and setting the fourth condition display unit 401d in FIG. 3). If the program reserved for recording is a PPV program and the update is not desired, a setting is made so that the update is not performed when the program is a PPV program (= FIG. 3). By selecting and setting the third condition display unit 401c), it is possible to prevent the update from being executed, so that the firmware can be updated more conveniently.
