  The input unit 401 outputs a program guide display request input from an input device (not shown) such as a remote controller to the control unit 402.

  The TS processing unit 402 separates the TS input from the receiving unit 201 into SDL trigger data, software main body, program guide data, and AV content. Then, the SDL trigger data, the program guide data, and the software main body are output to the data storage unit 404, and the AV content included in the program notified by the control unit 403 is output to the AV processing unit 207.

  The control unit 403 notifies the TS processing unit 402 of the program selected by the receiving device 400. Also, an SDL importance determination request is output to the SDL importance determination unit 205. Then, based on the determination result input from the SDL importance determination unit 205 and the program table display request input from the input unit 401, an SDL program table creation request is output to the OSD display control unit 405. Further, based on the SDL trigger data input from the data storage unit 404, the software main body stored in the data storage unit 404 is replaced with the current software existing in the nonvolatile memory (not shown).

(Embodiment 3)
FIG. 9 is a block diagram showing a software download system according to Embodiment 3 of the present invention. The software download system includes a digital broadcast transmission device 300 and a digital broadcast reception device 600, and is implemented in that processing according to the SDL importance is performed when the SDL execution time and the program viewing recording reservation time overlap. This is different from the second form. Here, the components having the same functions as those in FIG.

  The digital broadcast receiving apparatus 600 includes a receiving unit 201, a TS processing unit 401, a control unit 602, a data storage unit 603, an SDL importance determination unit 205, an OSD display control unit 604, an AV processing unit 207, It comprises an AV output unit 605, an input unit 606, and a reservation management unit 601.

  The reservation management unit 601 manages program reservation data input from the control unit 602.

  The control unit 602 creates program reservation data composed of an ID for identifying a reserved program based on the reservation information input from the input unit 606 and the program guide data stored in the data storage unit 603, and generates a reservation management unit. Output to 601. Also, the program selected by the digital broadcast receiving apparatus 600 is notified to the TS processing unit 401. Also, an SDL importance determination request is output to the SDL importance determination unit 205. Then, based on the determination result input from the SDL importance determination unit 205 and the program reservation data managed by the reservation management unit 601, an output of a duplicate notification creation request to the OSD display control unit 604 and the SDL to the data storage unit 603 are performed. Outputs availability information. Further, based on the SDL trigger data and SDL execution availability information input from the data storage unit 603, the software main body stored in the data storage unit 603 is replaced with the current software existing in the nonvolatile memory (not shown).

  When a duplicate notification creation request is input from the control unit 602, the OSD display control unit 604 creates duplicate notification data based on the SDL trigger data accumulated by the data accumulation unit 603 and outputs the duplicate notification data to the AV output unit 605.

  The AV output unit 605 synthesizes the video data input from the AV processing unit 207 and the duplicate notification data input from the OSD display control unit 604, converts the data into analog data, and then displays the video signal as a display device such as a monitor. Output to. Also, the audio data input from the AV processing unit 207 is converted into analog data, and then output as an audio signal to an audio output device such as a speaker.

  The input unit 606 outputs reservation information input from an input device (not shown) such as a remote controller to the control unit 602.

  Next, SDL duplication processing control according to importance in Embodiment 3 of the present invention will be described using the flowchart shown in FIG. The same processes as those in FIG. 7 are denoted by the same reference numerals and description thereof is omitted.

  In digital broadcast receiving apparatus 600, when control unit 602 overlaps either the SDL execution time and the program viewing recording time zone (time zone from the program viewing recording start time to the program viewing recording stop time) in the program reservation data When the determination result of the SDL importance is “high SDL importance” (“YES” in S301, “YES” in S302), the result is sent to the AV output unit 605 via the OSD display control unit 604. A duplicate notification screen indicating that SDL is prioritized is displayed (S303), and “SDL execution possible” is stored in the data storage unit 603 as SDL execution availability information.

  Further, when either the SDL execution time and the program viewing recording time zone in the program reservation data overlap and the determination result of the SDL importance is “SDL importance is small” (“ “YES”, “NO” in S302), the OSD display control unit 604 causes the AV output unit 605 to display a duplicate notification screen indicating that program reservation is prioritized (S304), and “SDL execution information” as SDL execution availability information. “No” is stored in the data storage unit 603.

  Here, a duplicate notification screen displayed on the AV output unit 605 is shown in FIG. The overlap notification screen 110 displays whether to prioritize SDL or program reservation.

  On the other hand, in the control unit 602, when neither the SDL execution time nor the program recording time zone in the program reservation data overlap (“NO” in S301), the overlap notification screen is not displayed.

  Then, the above processing is continued until the SDL execution time (“NO” in S301 to S305). When the SDL execution time is reached (“YES” in S305), the SDL execution availability information stored in the data storage unit 603 is displayed. Based on this, SDL execution or SDL execution cancellation is performed (S306).

  In addition, a button for obtaining the user's consent, such as “Yes” or “No”, is added to the duplicate notification screen 1100, and SDL execution availability information is created based on the user's wish input via the input unit 601 as a final determination. May be.

  In addition, the overlap between the SDL execution and the program reservation has been described. Even when the SDL execution and the user's viewing behavior overlap, for example, when an attempt is made to view a program during the SDL execution, the overlap notification screen 1100 is displayed. The process to be displayed may be determined and executed after obtaining the final judgment of the user.

  According to the third embodiment, when the SDL implementation and the user action overlap, it is possible to change the priority process according to the SDL importance. Furthermore, by notifying the user of the priority process, the user can easily check which process is scheduled to be performed. The user can reset the reservation. As a result, when the conventional SDL overlaps with the user action, the fact that the user did not know that it overlapped with the SDL can make the SDL implementation more conscious and improve the SDL implementation rate. .

  The software download system of the present invention can increase the SDL implementation rate by notifying the user of the SDL implementation time in advance or performing processing according to the importance of the SDL. This is useful for a device having a software download function that can be upgraded.
