Description

  The present invention relates to a software update technique in a strong layer receiver, for example, a digital broadcast receiving apparatus that receives a strong layer or a strong layer and a middle layer of a digital broadcast wave.

  In connection with downloading via broadcast waves, this is a technology that uses a communication function to update software using a high-level receiver, and allows the update software to be downloaded without using a download device installed at a store or the like. There is a technology (see Patent Document 1).

JP 2004-187178 A

  However, the technique described in Patent Document 1 proposes a means for a strong layer receiver to perform software update using a communication function, and is poor in versatility in that the communication means is an essential requirement. There is a problem that is limited.

  Further, in order for the user to update the software, the user has to search for the location information of the store separately, which is not convenient.

  It is an object of the present invention to provide a method for downloading updated software in a strong hierarchical receiver that does not require communication means as an essential requirement.

  SDTT (Software Download Trigger Table) refers to a table for sending software download notification information (schedule information, etc.). Text information is stored in an area called text_char in the strong hierarchy SDTT. This area is provided for notification to be transmitted as text information by displaying the message as a message from the manufacturer or broadcaster to the receiver user.

  The present invention is characterized in that the information that can be read by the user and obtained by the receiver for the location information of the service station is described in the notice.

  More specifically, a certain format is provided in the text area and, for example, the following description is provided.

“This receiver requires a software update.
Please bring the receiver to the following service station.
★ Minato-ku, Tokyo *** 1-9-2 03-0000-0000
★ Yokohama City Midori Ward *** 5-10 045-000-0000
★ ＊＊＊＊＊＊＊＊
Do you want to see the map of the nearest service station location from your current location? "

  In this way, the part following the one-byte full-width space + ★ mark from the beginning of the line is defined as an address description area, and is structured so that it can be read as text by the user and recognized as address data by the receiver.

  Along with the text information, there is a private_data_byte part that can be freely used by the receiver manufacturer. In this area, the purpose of use as in the text area is not fixed, so that it is not necessary for the user to read everything, and only address data of the service station can be described.

  According to one aspect of the present invention, the location information of a service station is presented in a text_char provided in the strong hierarchy SDTT and used to display a message from the receiver manufacturer or broadcaster in the form of text information. There is provided a strong hierarchical receiver characterized in that a description is made. It is preferable to define and provide an address description area in the text information description area. This forms a mechanism that can be read as text by the user and recognized as address data by the receiver.

  The address data of the service station may be described in a private_data_byte which is an area different from the text information and can be freely used by the receiver manufacturer. Thereby, since the purpose of use such as a text area is not determined, it is not necessary for the user to read everything, and only address data of the service station can be described.

  The present invention also provides an access method to an updatable service base when receiving notification of software update of a strong layer receiver, and therefore has an advantage that software update is easy to use. .

  Hereinafter, a software update technique for a strong hierarchical receiver according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a software update system for a strong layer receiver according to the present embodiment. As shown in FIG. 1, the system according to the present embodiment includes a strong hierarchy receiver 1 (including a strong hierarchy reception unit and an antenna 3) with a position detection function, for example, a GPS function (position detection unit), and a strong hierarchy SDTT. Broadcasting station 11, GPS satellite 15, and service base 21. The strong hierarchical receiver 1 is configured to be able to hold or acquire map information (GIS) from the outside (map information acquisition unit). The SDTT includes a manufacturer ID of the strong hierarchy receiver 1, a model ID, receiver identification information, and text information. Further, although not shown in the figure, for example, whether or not the receiver is a target receiver based on the manufacturer ID information and the model ID information acquired when the strong hierarchy SDTT is received by the cooperation of the CPU and the program in the ROM. It has the target receiver determination part which performs determination.

  The system searches for a shop or service base with a software update facility closest to the current position based on the current position information by GPS and the position information of the software update service base, and the closest software update base on the map To the user (for example, display on the display unit 5).

  The navigation of the map display 7 can guide the user to move to a shop or service base 21 having a software update facility. At this time, by sending an e-mail to the strong layer receiver 1, the service base can be presented to the user. That is, reception of the strong layer SDTT is used as a common trigger, and the following two methods are used. Present your service base at. 1) The self-location is confirmed by the GPS function, and nearby update facilities (service bases, sales shops, etc.) are displayed on a screen (on a map, etc.). 2) Confirm the self-location from the positional relationship with the communication master station (determined by three-point distance measurement, etc.), and display a nearby update facility (service base, dealer, etc.) on the screen (on a map, etc.).

  At that time, the user can make a reservation for the update at the service base by replying or forwarding the electronic mail.

  2 to 5 are flowcharts showing the flow of various processes including the above 1) and 2). As shown in FIG. 2, first, a strong hierarchy SDTT is received in step S1, and manufacturer ID information and model ID information are acquired in step S2.

  In step S3, based on the manufacturer ID information and model ID information, it is determined whether or not it is a target receiver. If it is not the target receiver (N), this task is terminated (step S13). If it is the target receiver (Y), in step S4, the text information including the location information regarding the service station that provides the software update service is acquired, and the text information is stored in a nonvolatile memory (Flash) or the like.

  Next, in step S5, the text information is displayed on the display screen. As an example of display, “A message indicating that software update is necessary is displayed to the user, and the user's operation regarding whether or not to display the nearest service station is prompted. Specifically, Yes or No is input to the user. (Waiting for an instruction from the user in step S6) If the instruction is given by the user in step S7, the process ends if No (step S14), otherwise the process proceeds to step S9. Next, in step S10, the GPS is activated to acquire the current position information of the strong layer receiver 1. In step S11, the nearest service station of the strong layer receiver 1 is searched. The nearest service station map information is displayed on the strong receiver 1 Is displayed on the surface. Alternatively, it is also possible to initiate guidance by GPS.

  FIG. 3 is a flowchart showing the flow of processing according to the modification of FIG. Steps S21 to S31 are the same as steps S1 to S11 in FIG. Next, in step S32, it is determined whether or not the nearest service station is within walking distance from the current position. If it is within walking distance (Y), the process proceeds to step S33, where the nearest service station map information is displayed on the mobile screen, or guidance by GPS is started. If it is not within walking distance (N), the process proceeds to step S34 to display on the display screen that there is no service station nearby. Next, in step S35, the user is asked whether to notify the user (receiver 1) when approaching the service station. Specifically, a display prompting the input of Y or N is performed. The map application is terminated in step S36, and the GPS measurement is terminated in step S37. In step S38, an instruction from the user is awaited. When there is an instruction from the user in step S39, in step S40, if the user judgment is a judgment that the guidance to the service station is not desired (N) In step S46, the process ends. If it is determined in step S40 that the user's determination is to request guidance to the service station (Y), a service station in the walking area is periodically searched in step S43, and a walk from the current position is performed in step S44. It is determined whether or not there is a service station in a service area (for example, within 10 minutes can be set). If the service station is in the walking area in step S44 (Y), the process proceeds to step S33, and the nearest service station map information is displayed. Display on mobile screen. Alternatively, GPS guidance is started. In the step of determining whether or not it is within walking distance, the required time on foot or the required time when using the transportation means and the access method may be displayed on the display screen. That is, when the service station is approached to some extent, the user is notified of that. At this time, it is preferable to continuously search for service stations.

  When the above processing is used, information related to access to the service station when receiving the download service is also presented to the user, and there is an advantage that convenience for the user is improved.

  FIG. 4 is a flowchart showing a modification of the processing shown in FIGS. Basically, the process is the same as that shown in FIG. 3, but in step S75, it is determined whether or not the service station is in the walking area. If it is determined that the service station is in the walking area (Y), in step S76. When a buzzer sound or the like is actually generated and the user walks toward the service station on foot, if the user gets close to the service station to some extent, for example, a buzzer sound is sounded to notify the user. When the user hears the buzzer sound, for example, the receiver placed in the pocket is taken out, and in step S63, the nearest service station map information is displayed on the portable screen or guidance by GPS is started.

  By using the above processing, there is an advantage that the user can easily reach the service station without walking while constantly viewing the map display.

  FIG. 5 is a flowchart showing a modification of the processing shown in FIGS. Steps S81 to S84 are the same as the processes shown in FIGS. However, in step S85, the user is informed that the software needs to be updated, asked whether or not to display a service station near the home, and provided with a user interface that can respond with Yes or No. To do. If the user gives a response to display a service station near his / her home, the service station nearest to his / her home is searched in step S90, and the service station in the desired area (near his / her home) is searched in step S91. In step S92, the map information of the nearest service station is displayed on the screen. In the case of No, the process proceeds to step S93 to display that there is no service station nearby, ask whether or not the nearest search by GPS is desired, and so that the user can respond with Yes or No, for example, Provides a user interface. Here, the map application is terminated (step S95), and an instruction from the user regarding step S94 is awaited (step S96).

  In step S97, the user gives an instruction, and in step S98, if the user's judgment is that the nearest search is not necessary (N), the process is terminated (step S104). If the nearest search is necessary (Y), the map application is activated again in step S99, GPS is activated in step S100, and current position information is acquired. Next, in step S101, a service station in the walking area is periodically searched, and in step S102, it is determined whether or not there is a service station in the walking area. Display map information on the mobile screen.

  The feature of this process is when there is no service station near the home, and when the user desires the nearest search by GPS, for example, the service station in the walking area is periodically searched by starting GPS, If it is in the service area, a map useful for accessing the service station is displayed on the screen. Thereby, the user can receive the download service either near his home or on the go.

  As described above, according to the software update technique for the strong layer receiver according to the present embodiment, when the strong layer SDTT is received in the download of the strong layer receiver without software update, the user is notified. On the other hand, by indicating where the nearest update facility (sales shop, etc.) is, it is possible to receive a method for easily updating software without changing the specifications of the current receiver. That is, since an access method to an updatable service base is also provided, there is an advantage that software update is easy to use.
