  Hereinafter, embodiments of a display device according to the present invention will be described with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and detailed description of common features will not be repeated.

  FIG. 1 is a schematic configuration diagram of a broadcast receiving apparatus (television receiver) 100 capable of displaying an OSD according to an embodiment of the present invention.

  Referring to FIG. 1, broadcast receiving apparatus 100 connects antenna 63 and monitor 40 and receives a command signal from external remote controller (abbreviation of remote controller) 62. The antenna 63 receives a broadcast signal and outputs the received broadcast signal to the broadcast receiving device 100. The monitor 40 receives the video signal and audio signal output from the broadcast receiving apparatus 100, outputs an image on the screen, and outputs audio from the speaker.

  The antenna 63 receives a digital television broadcast signal which is a high frequency RF (Radio Frequency) signal transmitted by radio waves from a television broadcast station (not shown), converts the digital television broadcast signal into an IF (Intermediate Frequency: intermediate frequency signal), and broadcasts it. The data is output to the receiving device 100.

  The remote control 62 accepts an operation by the user and transmits a command signal corresponding to the operation to the broadcast receiving apparatus 100 by infrared rays. The output from the remote controller 62 is not limited to an infrared signal, and may be a wireless signal. Further, instead of the remote control 62 and the remote control receiving unit 26 described later, or together with the remote control 62 and the remote control receiving unit 26, the main body of the broadcast receiving apparatus 100 accepts an operation from the user and sends an operation signal to the control unit described later. 10 may be provided with an operation accepting unit that outputs to 10.

  The broadcast receiving apparatus 100 includes a control unit 10, a tuner 16, a digital demodulator 18, an MPEG decoder 22 having a decoding function according to an MPEG (Moving Picture Experts Group) corresponding to an HD broadcast encoding method, a signal processing unit 23, A power supply (abbreviated as PWR in the drawing) unit 29 for supplying power to each unit of the broadcast receiving apparatus 100 is included.

  The control unit 10 includes a CPU (Central Processing Unit) 10A that executes a program and a memory 10B that stores various data.

  The tuner 16 receives a broadcast signal received via the antenna 63, and corresponds to a physical channel selected from the input broadcast signal according to an instruction from the CPU 10A (including information on a physical channel to be selected). The broadcast signal to be extracted is extracted and output. The tuner 16 outputs the extracted broadcast signal to the digital demodulator 18.

  The digital demodulator 18 receives the broadcast signal from the tuner 16, demodulates the broadcast signal into a TS signal in which video and audio are digitally encoded, and outputs the TS signal to the MPEG decoder 22.

  The MPEG decoder 22 inputs a given TS (Transport Stream) signal and decodes it into a video signal and an audio signal. Then, the decoded video signal and audio signal are output to the signal processing unit 23. The signal processing unit 23 processes the signal so that the video signal and audio signal input from the MPEG decoder 22 can be output to the monitor 40, and outputs the signal-processed video signal and audio signal to the monitor 40. The monitor 40 displays a given video signal as an image and outputs an audio signal from a speaker (not shown).

  The MPEG decoder 22 can also extract predetermined information from a given TS signal and create a channel list. The created channel list is stored in a predetermined area of the memory 10B of the control unit 10, for example.

  The signal processing unit 23 includes an OSD (On Screen Display) circuit 231. The OSD circuit 231 generates an image signal based on the data supplied from the control unit 10 and superimposes the generated signal on the video signal output from the signal processing unit 23 and outputs the image signal to the monitor 40. Thereby, the video of the program on which the image based on the data is superimposed is displayed on the screen of the monitor 40.

  Here, standards applied to digital television broadcasting include, for example, the Japanese ISDB-T (Integrated Services Digital Broadcasting for Terrestrial) standard, the US ATSC (Advanced Television Systems Committee) standard, and the European DVB-T ( Digital Video Broadcasting for Terrestrial) standard. In any of the standards, the content of the logical channel multiplexed on the physical channel is encoded in accordance with either HD broadcast or SD broadcast.

  In the present embodiment, for example, digital television broadcasting according to the European DVB-T standard (ETSI (European Telecommunications Standards Institute) EN 300 468) will be described as an example.

  The broadcast receiving apparatus 100 according to the present embodiment can change the setting of the OSD display language (hereinafter referred to as “OSD language”) during operation after activation.

  Specifically, the OSD language is an initially set language when the broadcast receiving device 100 is first activated (or when the setting in the broadcast receiving device 100 is reset).

  Then, based on information input from the remote controller 62, information for changing the setting of the OSD language is received, and the setting of the OSD language is changed based on the information. The control unit 10 controls the OSD display contents of the OSD circuit 231 in accordance with the operating state of the broadcast receiving apparatus 100, and controls the OSD language based on the OSD language setting information.

The memory 10B has an area for storing the OSD language setting contents.
FIG. 2 is a diagram illustrating an example of a screen that the broadcast receiving apparatus 100 displays on the monitor 40 in order to change various settings.

  Referring to FIG. 2, screen 410 shows items whose settings are to be changed. Specifically, “OSD language” is displayed as the item 411, and “hue” is displayed as the item 412. When the item 411 is selected for the screen 410, the monitor 40 displays a screen for setting the OSD language. An example of the screen displayed at this time is shown in FIG.

  Referring to FIG. 3, screen 4110 is a screen for setting the OSD language. A pull-down menu 4111 is displayed on the screen 4110. The pull-down menu 4111 displays a plurality of items 4111A to 4111C that can be selected. The item 4111A corresponds to a character string describing the language “English” in the language. The item 4111B corresponds to a character string describing the language “Japanese” in the language. The item 4111C corresponds to a character string describing the language “German” in the language.

  The control unit 10 displays the screen 410 on the monitor 40 based on information input via the remote controller 62, and further displays the screen 4110 on the monitor 40 based on the input of predetermined information. Then, the language corresponding to the item selected based on the information input via the remote control 62 from the items displayed in the pull-down menu 4111 is accepted as the information for setting the OSD language. In addition, the control unit 10 stores the received information in the memory 10B.

  Further, in the broadcast receiving apparatus 100, in addition to the latest setting information for the OSD language set via the screen 4110, the previously set information is also stored in the memory 10B.

  An example of the storage mode of these languages in the memory 10B is shown in Table 1.

  Referring to Table 1, LANG_NOW is the latest setting information for the OSD language, and LANG_OLD is the previous setting language for the OSD language.

  In the initial state (for example, the state at the time of shipment) of the broadcast receiving apparatus 100, LANG_NOW and LANG_OLD do not store corresponding information as shown in Table 1.

  Then, when the OSD language is set for the first time via the screen 4110, as shown in Table 2, the language is stored as a language corresponding to LANG_NOW. In this state, LANG_OLD is not stored.

  Furthermore, when the OSD language setting is changed via the screen 4110, LANG_OLD is updated so that the language stored as LANG_NOW until then is stored, and the newly set language is set as LANG_NOW. Remembered.

  Table 3 shows a state in which “Japanese” is newly set as the OSD language via the screen 4110 from the state of Table 2.

  LANG_OLD in Table 3 is a language stored as LANG_NOW in Table 2. And LANG_NOW in Table 3 is a newly set language.

  As shown in Table 3, in the broadcast receiving apparatus 100 of the present embodiment, when the language set as the OSD language is changed, the language before the change and the language after the change are respectively LANG_OLD and LANG_NOW, It is stored in the memory 10B.

  When the broadcast receiving apparatus 100 is turned off and then turned on again and the broadcast receiving apparatus 100 is activated, the control unit 10 compares the languages LANG_NOW and LANG_OLD, and if they are different, the OSD language Display a confirmation screen for the settings of. An example of such a confirmation screen is shown in FIG.

  Referring to FIG. 4, screen 400 includes two types of messages for setting the OSD language. The message 401 is a message described in the language stored as LANG_NOW, and the message 402 is a message described in the language stored as LANG_OLD. Both the message 401 and the message 402 display operation contents for setting the OSD language to the language in which the message is described. In the example shown in FIG. 4, the screen 400 corresponds to the stored contents shown in Table 3. That is, the message 401 is a message for guiding the operation content for setting the OSD language in Japanese, and the message 402 is a message for guiding the operation content for setting the OSD language in English.

  When the OSD language is changed from English to Japanese by displaying the screen 400 when the broadcast receiving apparatus 100 is started (at power-on), the user of the current broadcast receiving apparatus 100 can change Even if the user cannot understand the Japanese language, since the guidance in English, which is the language before the change, is displayed on the screen 400, the user can easily change the OSD language according to the English guidance. You can set the language that you can understand.

[Description of processing contents]
Hereinafter, the contents of the process (OSD setting process) executed by the control unit 10 to perform the screen display as shown in FIGS. 2 to 4 in the broadcast receiving apparatus 100 are referred to FIG. 5 which is a flowchart of the process. To explain.

  Referring to FIG. 5, in the OSD setting process, control unit 10 first determines whether or not the power of broadcast receiving apparatus 100 is turned on in step S10, and proceeds to step S20 if it is determined that the power is turned on.

  In step S20, the control unit 10 executes a startup confirmation process and advances the process to step S30. The details of the startup confirmation process in step S20 will be described later with reference to FIG.

  In step S30, the control unit 10 determines whether or not an operation for changing the setting of the OSD language has been performed. If it is determined that the operation has been performed, the process proceeds to step S40. If not, the process proceeds to step S50. Proceed.

  In step S40, the control part 10 performs an OSD setting change process, and returns a process to step S30.

  Here, examples of the operation for changing the setting of the OSD language in step S30 include an operation of displaying the screen 410 of FIG. 2 and selecting the item 411 on the screen 410.

  The contents of the OSD setting change process in step S40 will be described with reference to FIG. 7 which is a flowchart of the subroutine of the process.

  Referring to FIG. 7, in the OSD setting change process, the control unit first determines in step S410 whether or not the changed content has been input. If it is determined that the input has been input, the control unit proceeds to step S420.

  Here, the input of the content after the change is, for example, information for selecting an item (any one of items 4111A to 4111C) corresponding to the language after the change from the pull-down menu 4111 on the screen 4110 in FIG. Input.

  In step S420, LANG_OLD in memory 10B is updated with the information stored as LANG_NOW until then, and the process proceeds to step S430.

  In step S430, the control unit 10 updates LANG_NOW of the memory 10B with the language accepted in step S410, and returns the process to FIG.

  Returning to FIG. 5, in step S50, the control unit 10 determines whether or not the power of the broadcast receiving apparatus 100 has been turned off. When it is determined that the broadcast receiving device 100 has been turned off, the control unit 10 ends the OSD setting process. The process returns to S30.

The startup confirmation process will be described.
Referring to FIG. 6, in the startup confirmation process, control unit 10 first determines in step S210 whether or not the setting of the OSD language has been changed. Return to On the other hand, if it is determined that the change has been made, the process proceeds to step S220.

  Here, whether or not the OSD language setting has been changed is determined based on whether or not LANG_NOW and LANG_OLD in the memory 10B are different. As shown in Table 2, even if the stored information of LANG_NOW and LANG_OLD are different, if the information is not yet stored in LANG_OLD, it is determined that the OSD language setting has not been changed.

  In step S220, the control unit 10 displays a confirmation screen on the monitor 40, and proceeds to step S230.

  Here, the confirmation screen is a screen including operation guidance for setting the OSD language in each of the languages LANG_NOW and LANG_OLD, as in the screen 400 of FIG.

  In step S230, the control unit 10 determines whether or not there is an input for setting the OSD language on the confirmation screen. If it is determined that there is an input, the process proceeds to step S240.

  In step S240, the control unit 10 determines whether information for selecting the old setting language (LANG_OLD) has been input. If it is determined that the information for selecting the old setting language has been input, the process proceeds to step S250. If it is determined that the information for selecting the latest setting language (LANG_NOW) has been input, the process proceeds to step S260.

  In step S250, the control unit 10 updates LANG_NOW with the language stored in LANG_OLD, and returns the process to FIG.

  For example, when step S250 is executed in the state shown in Table 3, as shown in Table 4, LANG_NOW is updated with the language of LANG_OLD, so that these languages are the same (both English).

  On the other hand, in step S260, the control unit 10 updates LANG_OLD with the language stored in LANG_NOW, and returns the process to FIG.

  For example, when step S260 is executed in the state shown in Table 3, LANG_OLD is updated with the language of LANG_NOW as shown in Table 5, so that these languages are the same (both Japanese).

  In the present embodiment described above, when the OSD language is set via the screen 4110 (see FIG. 3), the previous setting information is stored as LANG_OLD, and the latest setting information is stored as LANG_NOW. That is, in the present embodiment, the first information that is the latest designation information for the OSD language is configured by LANG_NOW. In addition, LANG_OLD constitutes second information that is the previous designation information for the OSD language.

  In the broadcast receiving apparatus 100, when the first information (LANG_NOW) and the second information (LANG_OLD) are different at the time of activation, the broadcast receiving apparatus 100 is specified by the language specified by the first information and the second information. A screen (a screen 400 including a message 401 and a message 402) for accepting input of information specifying the language of the OSD is displayed. The control unit 10 that displays such a screen constitutes a confirmation setting unit.

  When the language is set via such a screen, the stored contents of the memory 10B are updated so that both LANG_NOW and LANG_OLD become the set language.

  Accordingly, after the language is set via the screen as shown in FIG. 4, if the OSD language setting is not changed, such a screen is not displayed when the broadcast receiving apparatus 100 is activated. This is because LANG_NOW and LANG_OLD are the same language, so NO is determined in step S210, and step S220 is not executed.

  That is, in the present embodiment, when the OSD language setting is changed via the screen 4110, LANG_NOW and LANG_OLD become different, and a confirmation screen like the screen 400 of FIG. Can be displayed.

  Thereby, after the broadcast receiving apparatus 100 is operated by the first user, the second user operates, and the OSD language is changed to a language that the first user cannot understand by the second user. Even if it is a case, the 1st user sees the screen 400 displayed when the broadcast receiving apparatus 100 is started again, and the OSD language in the language (language before change) that he / she can understand is displayed. Based on the setting guidance, the OSD language can be reset to a language that the user can understand.

  If the OSD language setting is made via the screen 400 of FIG. 4 and the OSD language setting is not changed thereafter, the broadcast receiving device 100 is activated as shown in the screen 400 of FIG. The screen for setting the correct OSD language is not displayed. Accordingly, it is possible to avoid a situation in which such a screen is displayed unnecessarily and the user is required to perform an operation for setting the OSD language every time the broadcast receiving apparatus 100 is activated.

  Such a function is effective, for example, when the broadcast receiving apparatus 100 is installed in a place operated by an unspecified number of persons (for example, a private room of an accommodation facility or a public place such as a canteen).

  Further, the display device of the present invention is not limited to the broadcast receiving device as long as it can display the OSD in a plurality of languages, and may be another device such as a disk reproducing device.

  LANG_NOW and LANG_OLD described with reference to Tables 1 to 5 are stored in the memory 10B. In addition, when CPU10A has a time measuring function, it is preferable that LANG_NOW and LANG_OLD are memorize | stored with each set time. In this case, the CPU 10A can display the time at which the respective OSD languages are set together with the LANG_NOW and LANG_OLD guidance messages on the confirmation screen (screen 400) shown in FIG. Thus, the user can infer in what situation (for example, by whom) each OSD language is set from the language in which each OSD is set.

  The CPU 10A of the present embodiment described above executes the program stored in the memory 10B and the like, thereby executing the processing described with reference to FIGS. The function of the broadcast receiving apparatus 100 described in this specification is realized.

  Note that the program may be stored in the memory 10B from the time of shipment of the broadcast receiving apparatus 100, or may be installed in the broadcast receiving apparatus 100 via a network or the like. Further, the memory 10B may be configured to be detachable from the broadcast receiving device 100, and it is assumed that the memory device storing the program is traded as a product independently of the broadcast receiving device 100. it can.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
