Description

  The present invention relates to a digital broadcast receiving apparatus that downloads firmware using broadcast waves and a control method therefor.

  The current digital broadcasting is operated based on standards and operational rules established by the Association of Radio Industries and Businesses (ARIB). In the operation regulations defined by ARIB, a technique for downloading (DL) firmware (FW) of a digital broadcast receiving apparatus (hereinafter also simply referred to as “receiving apparatus”) using broadcast waves is defined. The manufacturer of the receiving device downloads firmware to the receiving device in accordance with this rule in units of manufacturers or products.

  When downloading the firmware to the receiving device based on the ARIB operation rules, the following is performed.

First, the manufacturer creates firmware that the receiving device wants to download and converts it into a format that can be sent out. Further, the transmission schedule for the firmware is determined such as the target receiving device, the scheduled transmission start time that is the time when the firmware transmission is started, and the scheduled transmission time that is the time that the firmware transmission is continued. And SDTT (Software
Download Trigger Table) and submit to the broadcaster along with the firmware.

  In firmware download (FWDL) using broadcast waves, the firmware itself is transmitted by the data carousel transmission method, and therefore the same firmware is repeatedly transmitted a plurality of times during the scheduled transmission time. Therefore, in order to download the firmware on the receiving device side, it is only necessary to successfully receive the firmware once among the repeated sending of the firmware, and it is not necessary to receive the firmware in other periods of the scheduled sending time. .

  However, in the conventional receiving apparatus, the tuner unit of the apparatus is tuned to a specific broadcast wave during the time when the firmware is being downloaded, so it is impossible to receive another broadcast wave with the tuner. become. For this reason, when the firmware download channel is different from the user's program viewing / recording channel, the firmware download is generally not executed with priority given to the user viewing / recording. As a result, the firmware download execution probability may be low.

  In relation to this, a technique has been proposed in which a scheduled download time is extracted from a firmware transmission schedule sent in advance, and is added to a program guide for display. This makes it possible for the user to be aware of the scheduled download time, so that the firmware download execution probability can be increased (for example, see Patent Document 1).

However, in the above-described conventional technology, the firmware transmission scheduled start time and the scheduled transmission time are extracted from the firmware transmission schedule, and the time corresponding to the total number of times the firmware is repeatedly transmitted to the user is stored in the program table as the download execution time. indicate. That is, it is presented so as to prevent viewing of the program for a time longer than the time required for actual downloading of firmware in data carousel transmission (one cycle of carousel), and the power-off time prompting the user is longer than necessary. There were cases where it increased. As a result, it may be difficult to sufficiently increase the execution probability of firmware download.

  The best mode for carrying out the present invention will be exemplarily described in detail below with reference to the drawings.

[Example 1]
FIG. 1 shows the configuration of a digital television receiver (hereinafter also referred to as “receiver”) according to Embodiment 1 of the present invention. This digital television receiver is an example of a digital broadcast receiver. In the present embodiment, the firmware to be updated in the receiving device is sent from the broadcasting station at a constant cycle by the carousel transmission method. The firmware can be downloaded when the receiving device receives the broadcast wave. In FIG. 1, a tuner 301 receives a broadcast wave signal received by an antenna.

  The tuner unit 301 performs processing such as composite, demodulation, and error correction on the input signal to generate digital data in a format called a transport stream (TS). In addition, tuning is performed to a specific frequency in accordance with inputs from the viewing / recording reservation unit 308, the DL processing control unit 309, and the remote control code reception / interpretation unit 312. The TS data generated by the tuner unit 301 is output to the TS demax unit 302.

  The TS demax unit 302 separates the TS data input from the tuner unit 301 into an audio stream, a video stream, and a data stream. Then, the respective data are output to the audio decoding unit 303, the video decoding unit 305, and the program guide creation unit 306, respectively. In addition, the firmware transmission schedule and the firmware main body are output to the DL processing control unit 309.

  The audio decoding unit 303 decodes the audio stream input from the TS demax unit 302, acquires audio data, and outputs the audio data to the audio output unit 304 and the viewing recording reservation unit 308. In addition, the video decoding unit 305 decodes the video stream input from the TS demax unit 302, acquires video data, and outputs the video data to the video synthesis output unit 307 and the viewing / recording reservation unit 308.

  In addition, the program guide creation unit 306 decodes the data stream input from the TS demax unit 302, acquires program information, creates a program guide, and outputs the program guide to the video composition output unit 307. At the time of program recording, the program information is output to the viewing recording reservation unit 308.

  The audio output unit 304 outputs the audio data input from the audio decoding unit 303 and the viewing / recording reservation unit 308 as an output signal to a speaker or the like. The video composition output unit 307 synthesizes the video data and the program table input from the video decoding unit 305, the program guide creation unit 306, and the DL presentation screen creation unit 313, and outputs them as an output signal to a display device such as a display. Also, the input from the viewing / recording reservation unit 308 is output to the display device.

The viewing / recording reservation unit 308 outputs a tuning instruction of a specific frequency to the tuner unit 301 in response to an input from the remote control code reception / interpretation unit 312. The input from the video decoding unit 305 and the program guide creation unit 306 is output to the data storage unit 311. Also, the DL processing control unit 309 is notified that viewing recording is being executed. Furthermore, the viewing / recording reservation unit 308 outputs the program viewing / program recording start time (reservation start time ) and execution time (reservation continuation time ) and execution time (reservation continuation time ) according to the program viewing reservation or program recording reservation by the user to the DL processing control unit 309. .

  The DL processing control unit 309 repeatedly outputs the firmware transmission schedule to the DL time deriving unit 314. In addition, a frequency tuning instruction is output to the tuner unit 301 at the download start time of the firmware input from the remote control code reception / interpretation unit 312 and during the download. Then, the firmware main body is input from the TS demax unit 302 and output to the data storage unit 311. When the firmware download is completed, a firmware update request is output to the FW update execution unit 310.

The repeated DL time deriving unit 314 extracts the scheduled transmission start time and scheduled transmission time of the firmware based on the firmware transmission schedule input from the DL processing control unit 309, and calculates the repeated DL time of the firmware. Then, the repeated DL time is output to the DL presentation screen creation unit 313.

  The DL presentation screen creation unit 313 creates a DL presentation screen using the firmware repeated DL time input from the repeated DL time deriving unit 314 and outputs the DL presentation screen to the video composition output unit 307. This DL presentation screen is a screen showing a plurality of download time candidates by showing how firmware is repeatedly downloaded. In addition, a selection cursor capable of selecting each of the repeated downloads is created and output to the video composition output unit 307. Further, when there is an input of cursor movement from the remote control code reception / interpretation unit 312, a new DL presentation screen after the movement of the selected cursor is created and output to the video composition output unit 307. In addition to the program guide, a program information list screen for all stations at the download time selected by the selection cursor is created and output to the video composition output unit 307.

  The data storage unit 311 stores inputs from the DL processing control unit 309 and the viewing / recording reservation unit 308. In addition, the firmware main body is output to the FW update execution unit 310. The FW update execution unit 310 uses the firmware body input from the data storage unit 311 to update the firmware. The remote control code reception / interpretation unit 312 interprets the input from the remote control and outputs the contents to the tuner unit 301, the DL processing control unit 309, and the viewing / recording reservation unit 308.

  Next, the firmware download processing procedure executed by the DL processing control unit 309 according to the first embodiment will be described with reference to the flowchart shown in FIG.

When this flow is executed, in S401, the DL processing control unit 309 acquires a firmware transmission schedule from the TS demax unit 302 prior to the firmware transmission. When the process of S401 is completed, the process proceeds to S402.

  In S402, the DL processing control unit 309 analyzes the manufacturer ID and the model ID described in the transmission schedule acquired in S401. When the process of S402 ends, the process proceeds to S403. In S403, it is determined whether or not the same manufacturer ID and model ID as the receiving apparatus are extracted from the transmission schedule. If the same manufacturer ID and model ID as those of the receiving apparatus are extracted, the process proceeds to S404. On the other hand, when the same manufacturer ID and model ID as those of the receiving apparatus are not extracted, the flow is temporarily terminated.

In S404, the DL processing control unit 309 requests the repeated DL time deriving unit 314 to calculate the repeated DL time of the firmware. When the processing of S404 ends, the process proceeds to S405.

  In step S <b> 405, the DL processing control unit 309 creates a DL presentation screen to be presented to the user based on the repeated DL time of the firmware calculated by the repeated DL time deriving unit 314, with respect to the DL presentation screen creation unit 313. Request. Then, the DL presentation screen is synthesized with the program guide by the video composition output unit 307 and presented to the user.

In S405, the process of synthesizing the DL presentation screen with the program guide and presenting it to the user is performed by causing the user to select the download start time from among the download start time candidates. This also uses each repeated DL time as a download start time candidate to perform a process of prompting the user to schedule the firmware download. When this process ends, the process proceeds to S406.

  In S406, it is determined whether or not the user has selected the download start time of the firmware based on the screen. If it is determined that the user has selected the firmware download start time, the process advances to step S407. On the other hand, if it is determined that the user has not selected the firmware download start time, the process advances to step S408.

  In S407, in response to the user selecting the download start time of the firmware based on the DL presentation screen combined with the program guide and the video, the DL processing control unit 309 downloads the firmware at the selected time. (Start). When the process of S407 ends, the process proceeds to S411. In S411, the DL processing control unit 309 requests the FW update execution unit 310 to update the firmware using the downloaded firmware. When the processing of S411 ends, this flow is temporarily ended.

  On the other hand, in S408, it is determined whether or not the scheduled transmission start time of the firmware described in the transmission schedule has come. If a negative determination is made here, the process returns to before S408 and the process of S408 is executed again. If the determination in step S408 is affirmative, that is, if it is determined that the scheduled transmission start time of the firmware described in the transmission schedule is reached, the process proceeds to step S409.

  In S409, it is determined whether or not the user has made a program viewing, viewing reservation, or recording reservation. If it is determined that the user has made a program viewing, viewing reservation, or recording reservation, the flow is temporarily terminated without downloading the firmware. On the other hand, if it is determined that the user has not made program viewing, viewing reservation, or recording reservation, the process proceeds to S410. In S410, the firmware is downloaded. When the processing of S410 ends, the process proceeds to S411 described above.

  Next, the procedure for calculating the repeated DL time performed by the repeated DL time deriving unit 314 will be described with reference to the flowchart shown in FIG.

  When this flow is executed, S501 is executed. Here, the repeated DL time deriving unit 314 extracts the scheduled transmission start time, scheduled transmission time, and firmware capacity of the firmware from the firmware transmission schedule input by the DL processing control unit 309. When the processing of S501 ends, the process proceeds to S502.

  In S502, the repeated DL time deriving unit 314 calculates the time required to send the firmware main body once from the firmware capacity and the firmware download transmission capacity (theoretical value). When the process of S502 ends, the process proceeds to S503.

  In S503, the number of times the firmware is repeatedly sent is calculated from the time taken to send the firmware main body once and the scheduled firmware sending time calculated in S502. When the processing of S503 ends, the process proceeds to S504.

  In step S504, the firmware DL DL time is calculated from the scheduled firmware transmission start time, the number of repeated transmissions, and the time for one transmission. When the process of S504 ends, this flow is temporarily ended.

In the present embodiment, the example in which the firmware repeat DL time is calculated by calculation from the firmware transmission scheduled start time, the scheduled transmission time, and the firmware capacity as described above has been described. However, for example, the scheduled transmission start time of firmware,
The relationship between the scheduled transmission time, the firmware capacity, and the repeated DL time may be examined in advance and mapped.

  Then, the firmware repeat DL time may be obtained by reading from the map the repeat DL time corresponding to the firmware scheduled transmission start time, the scheduled transmission time, and the firmware capacity obtained from the transmission schedule. Here, the case where the firmware repeat DL time is calculated and the case where the repeat DL time is obtained by a method other than calculation such as reading from the map are expressed as “deriving the firmware repeat DL time”.

  Next, the DL presentation screen creation procedure performed by the DL presentation screen creation unit 313 will be described with reference to the flowchart shown in FIG.

  When this flow is executed, first, in S601, the DL presentation screen creation unit 313 acquires the repeated DL time from the repeated DL time deriving unit 314. When the process of S601 ends, the process proceeds to S602.

  In S <b> 602, the DL presentation screen creation unit 313 creates a screen (DL presentation screen) showing how firmware is repeatedly downloaded in consideration of displaying it superimposed on the program guide. When the process of S602 ends, the process proceeds to S603.

  In S603, the DL presentation screen creation unit 313 creates a selection cursor for selecting each of the repeated DL times. When the process of S603 ends, the process proceeds to S604.

  In S604, the DL presentation screen creation unit 313 creates a program information list screen for all stations in the time zone selected by the selection cursor. When the process of S604 ends, the process proceeds to S605.

  In step S <b> 605, the DL presentation screen creation unit 313 outputs the created screen to the video composition output unit 307, and requests that the screen be synthesized and displayed on the program guide. When the process of S605 ends, the process proceeds to S606.

  In S606, it is determined whether or not there is a cursor movement request by remote control operation, that is, whether or not there is an input of cursor movement from remote control code receiving / interpreting unit 312. If it is determined that there is a cursor movement request by remote control operation, the process proceeds to S607. On the other hand, if it is determined that the cursor movement request by the remote control operation has not been made, this flow is once terminated. In S607, the screen after the selection cursor is moved is created. When the process of S607 ends, the process returns to the process before S604.

  FIG. 5 shows an example of a diagram in which the screen created by the video composition output unit 307 in S602 showing the firmware being repeatedly downloaded and the selection cursor created in S603 are superimposed on the program guide. Show. It can be said that the download start time candidates are displayed on the screen so as to overlap the program guide. FIG. 6 shows the program information list screen created in S604.

  Next, an example of a user operation when the screens shown in FIGS. 5 and 6 are displayed will be described. In FIG. 5, the times indicated by t1 and t2 correspond to scheduled transmission start times. The time indicated by p1 and p2 corresponds to the scheduled transmission time. The time period determined by the scheduled transmission start times t1 and t2 and the scheduled transmission times p1 and p2 is also referred to as a download period hereinafter. A plurality of RDLt existing in each download period indicates one of the repeated DL times.

  In the process of S405 described above, the program guide, the DL presentation screen, and the selection cursor related to the firmware download period (first download) executed most recently are displayed in an overlapping manner. This process is performed immediately after the firmware repeat DL time is calculated in S404 (the program table, the DL presentation screen, and the screen in which the selection cursor is displayed in S405 are also referred to as a data carousel-added program guide below). ). If the receiving apparatus is not turned on when the transmission schedule is received, the program table with the data carousel is displayed when the power is turned on for the first time after receiving the transmission schedule. In the current operation, the SDTT describes a transmission schedule for two days, in which 2-4 scheduled transmission start times are set. Therefore, the “first time” expressed here indicates the first download.

  In the process of S405 described above, the program guide with data carousel is also displayed when the user manually starts the program guide when the firmware repeat DL time is calculated in S404.

  Then, from the program table with data carousel displayed in S405, the user selects the time of one data carousel where the firmware is to be downloaded with the selection cursor while confirming the program contents. At that time, the program information list screen shown in FIG. 6 is also referred to. For example, in the example of FIG. 5, the viewing reservation of the X station to which the firmware is sent at that time is made. In S407, the station X is selected and downloaded at the time when viewing reservation is made by the user. Note that the receiving device re-selects the last channel that was selected before the download was started after the download was completed.

  Further, when the user refuses the viewing reservation of the X station where the firmware is downloaded, or when the selection operation by the user is not performed for a certain period of time, the display of the program table with the data carousel is terminated.

  In addition, for example, if the download is not performed during the first download period, the receiving device, when the first download period has passed, the data carousel for the next download period related to the transmission start time closest to Display the attached program guide. Here, the case where the download is not performed during the download period includes the case where the viewing reservation is not made by the user and the case where the user selects a station other than the X station during the download. When the first download period has passed, the firmware download period closest to the next time zone indicates a download period related to the second scheduled transmission start time described in the transmission schedule.

  Further, when the download is not performed in the second download period, the receiving apparatus performs a viewing reservation selection process in the next download period (third download period). As described above, in this embodiment, until the download is performed, the user is provided with an opportunity to select viewing reservations for the X station for the number of times of the scheduled transmission start time described in the transmission schedule (the number of times of the download period). .

  As described above, in this embodiment, paying attention to one data carousel necessary for downloading firmware to the receiving apparatus, a plurality of download start time candidates are presented to the user in a program table format. Then, the user is made to select the download start time. Therefore, it is possible to reduce the probability that the download prevents the user from watching the program, as compared with the case where only the entire download period acquired from the transmission schedule is presented and the user reserves the download start time. As a result, it is possible to increase the download execution probability.

  In the present embodiment, an example in which the user is shown both the program table with a data carousel and the program information list screen and the user selects the start time of download has been described. It is not an essential requirement of the present invention.

[Example 2]
Next, a second embodiment of the present invention will be described. FIG. 7 is a diagram illustrating the configuration of the digital television receiver according to the present embodiment. Hereinafter, the description according to the second embodiment will be described only with respect to differences from the first embodiment.

  The viewing / recording reservation unit 908 in FIG. 7 displays the reservation start time that is the start time of program viewing and program recording reserved by the user and the reservation duration that is the duration of reserved program viewing and program recording. The data is output to the processing control unit 909. The repetition DL time deriving unit 913 calculates the repetition DL time, and outputs it to the DL processing control unit 909. The DL processing control unit 909 schedules the download start time of the firmware from the repeated DL time, the time required for one download of the firmware, the reservation start time of the viewing recording reservation and the reservation continuation time.

  Next, the procedure for scheduling the download start time performed by the DL processing control unit 909 in this embodiment will be described with reference to the flowchart of FIG.

When this flow is executed, in step S1110, the DL processing control unit 909 acquires a firmware transmission schedule from the TS demax unit 902. When the processing of S1110 ends, the process proceeds to S1111. In S1111, the DL processing control unit 909 analyzes the manufacturer ID and model ID described in the transmission schedule acquired in S1110. When the process of S1111 ends, the process proceeds to S1112.

  In S1112, it is determined whether or not the same manufacturer ID and model ID as the receiving apparatus are extracted from the transmission schedule. If the same manufacturer ID and model ID as the receiving apparatus are extracted, the process advances to step S1113. On the other hand, if the same manufacturer ID and model ID as the receiving apparatus are not extracted, the flow is temporarily terminated.

In S1113, the DL processing control unit 909 requests the repeated DL time deriving unit 913 to calculate the repeated DL time. When the process of S1113 ends, the process proceeds to S1114.

  In S <b> 1114, it is determined whether or not a program viewing reservation or recording reservation has been made by the user before the firmware repeated DL time calculated by the repeated DL time deriving unit 913. If the determination is affirmative, the process proceeds to S1115. On the other hand, if a negative determination is made, that is, if the user has not made a program viewing reservation or recording reservation before the calculated firmware repeat DL time, the process advances to step S1119.

In S1115, it is determined whether or not the program viewing or program recording related to the user reservation overlaps with the firmware download. More specifically, first, the period during which the actual download is performed is determined by the repeated DL time and the time required for one download of the firmware. On the other hand, a period during which program viewing or program recording by reservation is carried out is determined by the reservation start time of program viewing or program recording by the user and the reservation continuation time of program viewing or program recording. Then, it is determined whether or not both periods overlap. If it is determined that the firmware download and the program viewing or program recording reserved by the user overlap, the process advances to step S1116. On the other hand, if it is determined that the firmware download and the program viewing or program recording reserved by the user do not overlap (because it is not necessary to change the firmware download start time), the process advances to step S1119.

  In step S1116, a repetitive DL time other than the user's viewing recording reservation time is calculated. When the process of S1116 ends, the process proceeds to S1117. In S1117, it is determined whether or not there is time to download the firmware for one time. If a positive determination is made here, the process proceeds to S1118. On the other hand, if a negative determination is made, this flow is temporarily terminated.

  In S1118, in response to the fact that the time for downloading the firmware for one time remains in S1117, the latest repeated DL time is set as the firmware download start time.

The processing of S1114-S1118 is a program viewing or program recording reserved by the user, as the downloading of the firmware does not overlap, have you line scheduling of downloads. Further, each repeating DL time by using the download start time candidates, running scheduling of downloads of the firmware. In addition, the scheduling step in the present embodiment is configured including the processing of S1114 to S1118. When the process of S1118 ends, the process proceeds to S1119. On the other hand, if there is no time left to download the firmware once, the firmware is not downloaded.

  In step S1119, it is determined whether it is a firmware download start time. If it is determined that the firmware download start time has not arrived, the process returns to S1114. On the other hand, if it is determined that the firmware download start time has come, the process advances to step S1120.

  In S1120, it is determined whether or not the user is viewing a program. Here, when it is determined that the user is viewing the program, the flow is temporarily terminated as it is. On the other hand, if it is determined that the user is not viewing the program, the process proceeds to S1121.

  In S1121, the firmware is downloaded. When the process of S1121 ends, the process proceeds to S1122. In step S1122, the DL processing control unit 909 requests the FW update execution unit 910 to update the firmware using the downloaded firmware. When the process of S1122 ends, this flow is temporarily ended.

  As described above, in the second embodiment, paying attention to the data carousel for one time required for downloading the firmware to the receiving device, it is determined whether the firmware download and the user's program viewing reservation overlap. To do. If they overlap, the download at the current download start time is canceled and the download start time is changed to the start time for the next data carousel. Therefore, it is possible to increase the download execution probability by lowering the probability that the download will not be executed (cancelled) compared to the case where only the entire download period acquired from the transmission schedule is presented and the user reserves the download start time. It becomes.
