Description

  The present invention relates to a display device, a method, and a program. More specifically, the present invention relates to a television device, a display monitor, and the like that can be connected to other AV (Audio Visual) devices through a digital interface such as HDMI (High Definition Multimedia Interface). The present invention relates to a display device, a display method thereof, and a program to be incorporated into the display device.

  Video / audio transmission technology includes video / audio transmission method using MPEG compressed data according to IEEE (Institute of Electrical and Electronics Engineers) 1394 standard, component terminal, Y (luminance signal) / Pb (using D video terminal) There are a component video transmission system of blue color difference signal / Pr (red color difference signal), an optical digital audio transmission system in a digital audio format according to IEC (International Electrotechnical Commission) 60958 standard, IEC 61937 standard, and the like.

  Further, a DVI (Digital Visual Interface) standard is known as an interface for transmitting a digitized video signal at high speed between a computer main body and a display.

  The HDMI standard is a digital connection standard that is a further development of the DVI standard. In response to changes such as digitization of TV broadcasts and switching of display devices to flat panels, output such as STB (Set Top Box) in the home. The purpose is to digitally connect the device and the display.

  In this HDMI, a function of transmitting an audio signal and a control signal is added, and the requirement for TV use is satisfied. Conventional connections between devices use multiple cables for video, audio, and control signals, but the HDMI standard requires only one HDMI cable, and the control signal supports bidirectional transmission. Therefore, for example, by relaying a control signal from a monitor to an output device such as an STB or a DVD player connected via HDMI, the entire AV system (home theater, etc.) can be operated with one remote controller.

  As a prior art related to such HDMI, for example, Patent Document 1 discloses that a master / slave network including the HDMI standard is formed, a DDC (Display Data Channel) bus (one direction) and a CEC (Consumer Electronics Control) bus. A routing determination method and configuration in connection with (bidirectional) is disclosed. Japanese Patent Application Laid-Open No. 2004-228688 discloses a technique for reducing device setting work by acquiring device information using a connection based on HDMI and automatically converting the format (video / audio) of each device. Furthermore, Patent Document 3 discloses a technique for automatically matching when the specifications differ between an HDMI-compatible data transmission device and an HDMI-compatible data reception device.

In addition to the HDMI standard, there are a DisplayPort standard and a UDI (Unified Display Interface) standard as a standard developed from the DVI standard. The UDI standard is different from the HDMI standard in that it does not support audio signals, and the DisplayPort standard and the UDI standard are different from the HDMI standard in that connections are assumed not only between devices but also within devices.

  However, in recent years, the number of input terminals provided in a single device has increased, and for users, even if a system is built by connecting them, which external device is connected to which input terminal from the appearance of the system. It ’s hard to tell if it ’s connected. Therefore, even when an input switching operation screen (input switching menu screen) or channel call is displayed on the screen of a display device such as a television device, which input source should be switched to the user, from which external device It is hard to tell if the video is displayed.

  Actually, in the case of the channel call image 30 shown in FIG. 3A, even when an image is displayed using an external device connected to the fourth input terminal (here, HDMI input terminal) of the display device as an input source, The display device only displays an OSD (On Screen Display) such as “input 4” as the input display label 31 in response to the channel call, and does not know what device is connected. Here, the input display label is “input 1” for an external device connected to the input terminal 1, “input 2” for an external device connected to the input terminal 2, and so on. The terminal display name to represent.

  Therefore, a function that can arbitrarily change the input display menu screen or the input display label to be displayed as the channel call by user setting may be mounted on the display device. However, when this function is installed, only a fairly common name (eg, “TV”, “recorder”, “player”, etc.) can be realistically set as an input display label. Therefore, when there are a plurality of external devices of the same category and they are connected to the display device, the user needs to change the input display label between the external devices (actually between the input terminals).

  Furthermore, in such a user setting, since an input display label is assigned to each input terminal, when an external device is connected or disconnected or the power is turned on / off, it cannot be handled due to the presence of another external device. . That is, as the number of transmission devices with HDMI input terminals increases, in a television apparatus or the like having only one input terminal, the user needs to change the cable, and the display name is changed by selecting an input display. However, I don't know if the reconnected equipment fits that. For example, when a recorder is connected to an input terminal and the input display label “recorder” is set to the input terminal by the user, the game machine is connected when the recorder is disconnected from the input terminal and the game machine is inserted. In spite of this, the “recorder” display remains, or the input display label of the input terminal must be reset to “game machine” by the user.

The HDMI input terminals 1 and 2 (I / Fs 14 and 15) function as input terminals when the television apparatus 1 is used as a sink device, but function as HDMI output terminals when used as a repeater device or a source device.

  As described above, in the configuration example of FIG. 2, the recorder 5 and the AV amplifier 2 are directly connected to the HDMI input terminal of the television apparatus 1, and the two DVD players 3 and 4 are indirectly connected via the AV amplifier 2. Has been. These devices 2 to 5 form a hierarchical structure with respect to the television apparatus 1, and the recorder 5 and the AV amplifier 2 are the first hierarchy, and the DVD players 3 and 4 are the second hierarchy.

  Hereinafter, the terminal display name change process of the present invention, which is executed in the display system configured as described above or a system configured as an alternative, will be described. The television apparatus 1 according to the present invention includes at least the following model information acquisition unit and display name change unit in order to execute the terminal display name change process. These means (and means described later in other embodiments) may be incorporated into the system control unit 22 so as to be executable as a terminal display name change program as described above.

  The model information acquisition means receives a video packet and a model information packet from an external device (player 1 (3), player 2 (4), recorder 5, etc.) via the input terminal, from the model information packet. Get model information. The model information acquisition means only needs to be able to receive, for example, the above-described SPD packet in the television apparatus 1 and read the model information from the SPD packet. Therefore, the model information acquisition unit is incorporated in the television apparatus 1 illustrated in FIG. Yes.

  The display name changing unit changes the terminal display name representing the input terminal to be presented to the user to the external device display name based on the model information acquired by the model information acquiring unit. Here, as described above, the terminal display name indicates a display name representing an external device (input source to the input terminal) connected to the input terminal, and indicates “input 4” or the like. It should be noted that the terminals that cannot receive the SPD packet as exemplified in the external input I / Fs 11 to 13 in FIG. 1 are not subject to the terminal display name change processing in the present invention.

  FIG. 3 is a diagram illustrating an example of a channel call image displayed on the screen of the television device. Here, FIG. 3A shows an example of a channel call image in a conventional television apparatus, and FIGS. 3B and 3C are examples of the channel call image in the television apparatus to which the present invention is applied. Is shown. FIG. 4 is a diagram showing an example of an input switching menu of the television apparatus to which the present invention is applied. It is assumed that the terminal display name (input display) of the HDMI input terminal 1 (I / F 14) of the television apparatus 1 is “input 4”. It is assumed that the recorder 5 is connected to the HDMI input terminal corresponding to the input 4 with the configuration as shown in FIG.

  As an example of displaying the terminal display name, there is a display of a channel call image as illustrated in FIG. 3, and the terminal name changing process will be described with reference to FIG. 3 while comparing with the prior art. Conventionally, as illustrated in FIG. 3A, the channel call image 30 is used as the input terminal name (terminal display name) as illustrated in “input 4” 31, or the name selected by the user ( For example, “Recorder”) is used. Therefore, even if the connected device changes, the name is displayed as it is unless the user changes it. When there are a plurality of HDMI input terminals, in order to check which terminal the user has connected to, it is necessary to actually perform input switching and check the input and displayed video.

  On the other hand, in the present invention, the display name changing means changes the terminal display name (input display label) using the received model information. The model information includes manufacturer (manufacturer) name, model name, and category information, and it is only necessary to enable user setting of how to use and change the model information. This will be described later with reference to FIG.

  As an example of change by the display name changing means, for example, when an SPD packet from the recorder 5 whose manufacturer name is “SHARP” and category is “Recorder” is transmitted from the HDMI I / F 14, the conventional “input” It is also possible to change the display name to an external device display name such as “SHARP Recorder” instead of “4” 31 and display it on the channel call image. 3 (B) and 3 (C) show examples of display in an embodiment provided with model information collating means to be described later, but instead of “XX recorder” 34, 34a, “SHARP Recorder” is used. Can be displayed.

  In another example, when an external device whose model name is “DV-ARW15” is connected to the HDMI I / F 14, the external device display name may be changed to the character string “DV-ARW15” and displayed. it can. For example, “DV-ARW15” can be displayed instead of “XX recorder” 34, 34a in FIGS. Also, if the number of characters that can be displayed at one time is, for example, 10 characters due to display area limitations, SPD data can be set to a maximum of 16 characters, so if the name exceeds 10 characters, the font size is reduced. Or increase the display area, or cut off after 10 characters.

  In order to enable display of the channel call image as described above, the television apparatus 1 is provided with input source display means for displaying the terminal display name of the current input source on the screen, and in the display name changing means, The terminal display name to be changed may include the terminal display name of the current input source.

  The input source display means can be configured by the system control unit 22, the OSD processing unit 20a, the device driving unit 24, the display device 23, and the like. The input source that is currently outputting on the display device 23 in the system control unit 22 can naturally be grasped, and the terminal display name is transmitted to the OSD processing unit 20a to be displayed on the display device 23 and superimposed on the video. And display on the display device 23. Further, since the channel call image is displayed every time the channel is switched, the device name and state connected to the outside and serving as the input source can be seen at a glance each time the channel is switched.

  The input source display means may display the terminal display name changed by the display name changing means together with the default display name of the current input source. For example, “input 4” 31 and “DV-ARW15” (substitute for “XX recorder” 34, 34a) illustrated in FIGS. 3B and 3C, or “input 4 DV-ARW15” The terminal display name (external device display name) may be displayed in an integrated display (or a nearby position) with the TV channel call.

  Further, as another embodiment of the present invention, the following model information collating means may be provided. The model information collating unit collates (compares) whether the model information acquired by the model information acquiring unit matches a predetermined condition. The display name changing means changes the terminal display name representing the input terminal to be presented to the user to an external device display name corresponding to the predetermined condition when the model information matching means matches the predetermined condition. As the predetermined condition, a condition may be given to each of the three pieces of model information.

  For example, when the condition that the manufacturer name obtained from the SPD packet is an English sentence representing the company S and the category corresponds to “recorder” is satisfied, the display name changing means changes the terminal display name from “input 4” to the product name “XX recorder”. ”And the input source display means displays the channel call image 30 as exemplified in FIG. As a predetermined condition, for example, when the end of the model name, the beginning of the sentence, or the character string in the model name is “AR”, it may be changed to “XX Recorder”. This can be done without updating software and data.

  The channel call image 30 in FIG. 3B includes a “XXX recorder” 34, an input terminal type (here, HDMI) 32, and various types of information (here, video format and notification display). The channel call image 30a in FIG. 3C is a simplified display (small display) of the channel call image 30, and the external device display name “XX recorder” 34a is also displayed.

  Even if the number of input terminals increases, it is possible to know at a glance which device of which manufacturer is connected to which terminal. For example, when “XX Recorder” of S Company is connected, use a dedicated wording. Thus, it is possible to appeal that the OO recorder and the display device 1 are linked.

  The model information collating unit may be configured in the system control unit 22, for example. For example, a model information conversion table in which a plurality of sets of predetermined conditions and external device display names are associated with each other is stored in the EEPROM 22d, and a model information verification program (included in the terminal display name change program) stored in the ROM 22b is stored in the EEPROM 22d. It may be searched by referring to the model information conversion table whether there is a predetermined condition that matches. Then, as a result of the search, the display name changing means changes to the external device display name associated with the predetermined condition that matches with the model information conversion table.

  Actually, since the model information is inserted in the SPD packet in the ASCII code, the external device display name may be displayed using the ASCII code as it is, but if it matches the predetermined condition, it is used and displayed as it is. Instead, it is preferable to change to the external device display name as a result of searching in the model information conversion table, that is, to convert in the model information conversion table. Thereby, the name of a kanji, hiragana or katakana can be displayed as an external device display name corresponding to a predetermined condition.

  The example of displaying the terminal display name is not limited to the channel call image as shown in FIG. 3, but can be applied to the display of the input switching menu (input switching menu image) 40 as exemplified in FIG. In order to enable display of the input switching menu, the television apparatus 1 may be provided with switching menu display means for displaying the input switching menu of the input source on the screen. Then, the terminal display name to be changed by the display name changing means may include the terminal display name of the input source included in the input switching menu. Further, an input switching menu may be displayed in a general setting menu screen exemplified with reference to FIGS.

  The input switching menu includes the main body of the TV apparatus 1 (actually a TV tuner), external input I / F (external input 1 to external input 3) 11, 12, 13 and input I / F (HDMI input) from an HDMI device. 1 and HDMI input 2) are provided for switching the input source to be displayed on the display device 23 between 14 and 15. Data for displaying the input switching menu is held in the ROM 22b or EEPROM 22d of the system control unit 22 or the memory inside the OSD processing unit 20a, and is superimposed on the video by the OSD processing unit 20a and displayed on the screen of the display device 23. Is done. For example, the above-described switching menu display means may be configured by these components.

  Hereinafter, the display of the input switching menu will be described based on only the form in which the television apparatus 1 includes the model information collating unit. However, even if the TV apparatus 1 does not have the terminal display name without conversion from the model information as described above. It is only necessary to change the display name to the external device display name. In addition, as an input switching menu, only an example of adopting a method of switching input to direct selection is shown, but a method of switching while displaying only an input source selected by a toggle operation may be employed.

  The input switching menu 40 illustrated in FIG. 4 is a switching menu displayed when the display system as shown in FIG. 2 is constructed. Here, the input display labels of the input sources of the external input I / Fs 11 to 13 are shown. “Input 1” to “Input 3” which are (terminal display names) are displayed. The input switching menu 40 displays “OO recorder” 41 representing the input source of the HDMI I / F 14. This terminal display name is changed from the default terminal display name “input 4” by the above-described model information collating means and display name changing means, and is displayed.

  In addition, in the input switching menu 40 of FIG. 4, the display is different from that of other input sources. This makes it possible to express that “XX recorder” 41 is the currently selected input source. In addition, it is also possible to determine whether the connected external device is powered on / off and change the menu display according to the determination result. In addition, an external device that is currently disconnected but whose model information is stored in the EEPROM may be displayed in the same manner as when the power is turned off.

  In the switching menu 40, “OO player” and “ΔΔ player” 42 representing the input source of the HDMI I / F 15 are displayed. The two terminal display names 42 are changed from the default terminal display name “input 5” by the above-described model information collating means and display name changing means, and the remaining one is added and displayed. Alternatively, two terminal display names 42 may be displayed by dividing “input 5” into two. As a result, it is possible to display as if there are more input terminals than the HDMI terminals actually provided.

  As described above, even when two output devices are connected to one input terminal via a repeater device such as the AV amplifier 2, it is preferable that the display can be displayed in the input switching menu 40. In order to enable such two terminal display names 42, the model information acquisition means can be used even when a plurality of external devices are connected to the lower layer of the external device connected to one input terminal. In order to change the terminal display name in the display name changing means, model information may be acquired from a plurality of external devices. Actually, since the SPD packet is transmitted together with the video packet, acquisition from a plurality of external devices is possible only by inputting the video once.

  In the input switching menu 40, when a certain input source is selected by the operation button of the remote controller and the operation signal is received by the infrared light receiving unit 25, the system control unit 22 determines the target external device by the CEC command. An input switching instruction is issued. In the case of the recorder 5, an instruction may be given to the recorder 5. In the case of the player 1 or the player 2, the AV amplifier 2 is instructed to switch the input, and the AV amplifier 2 switches the HDMI input terminal of the AV amplifier 2 in accordance with the CEC command sent from the television apparatus 1 to the user. The stream is set in a state where it can be input from the designated HDMI input terminal.

  The remote control also has a move / decision button for moving the cursor position in the left / right / up / down direction at the time of setting, such as menus, and a decision operation to facilitate such operations. A return button for performing an operation for returning to the previous stage, an end button for performing an operation for ending each process, and a menu screen display button for performing an operation for displaying a menu screen for performing various settings of the television device 1 are provided. It is good to leave. The remote control includes other buttons such as a power button for turning on / off the power of the video display device, a channel selection button for performing an operation for selecting a channel number, and channel numbers upward and downward. Channel up and down buttons to select by operating in the direction, broadcast switching button for switching between analog broadcasting, digital broadcasting and IP broadcasting, input switching button for switching input sources including external devices, EPG Program guide display button for performing an operation for displaying, program information display button for performing an operation for displaying program information for a currently received program, and a simple operation when displaying an EPG screen, a menu screen, or the like Color (red, green, yellow, blue) buttons should be provided.

  5 and 6 are diagrams showing other examples of the input switching menu of the television device to which the present invention is applied. The input switching menus 50 and 60 illustrated in FIGS. 5 and 6 are not related to the display system construction example of FIG. In this example of display system construction, all external devices that have been connected once (however, when no other external device is connected to the same HDMI terminal) are displayed regardless of the current connection / disconnection status of the external devices. The input switching menu is displayed.

  The input switching menu 50 illustrated in FIG. 5 includes an external device display name 51 of S company such as “S company XX recorder 1” indicating an input source of the HDMI I / F 14 or I / F 15, and an external device of A company. A display name 52 and an external device display name 53 of company B are displayed. For example, in the external device display name 51 of the S company, the “S company” may be written only at the top or only one for the whole. In addition, the input switching menu 60 illustrated in FIG. 6 includes an external device display name 61 belonging to a recorder such as “S company XX recorder 1” indicating an input source of the HDMI I / F 14 or I / F 15, and belonging to the VTR. An external device display name 62, an external device display name 63 belonging to the digital camera, and an external device display name 54 belonging to the PC are displayed.

  Such a display can be realized by the switching menu display means rearranging the display of the terminal display name on the input switching menu based on the model information acquired by the model information acquisition means. For example, it is determined whether there are a plurality of model names or a plurality of categories with the same manufacturer name for an SPD packet from at least one HDMI terminal, and a device group for each manufacturer name or a category for each category is determined. Separate into equipment groups.

  For example, it is preferable to display a list by rearranging the devices with the same manufacturer name. For example, after extracting the manufacturer name of the external device, a list of external devices for each manufacturer name can be displayed in the lower layer of the input switching display, as in the external device display names 51 to 53. The model information is information including the manufacturer name, and the switching menu display means displays the terminal display name on the input switching menu for each manufacturer name. Depending on the user, there is a case where the TV is in-house and the recorder is another company. By this, it is possible to confirm at a glance what kind of equipment made by the company or other company (what kind of equipment) is connected. Can do. Further, if such usage (display) can be performed, it is convenient to move (copy) the data of the XX recorder 1 manufactured by S company to the XX recorder 2 manufactured by S company displayed at the bottom.

  In addition, for example, it is preferable to display a list by rearranging the devices in the same category. For example, after the category (recorder) of the external device is extracted, the external device display name 63 may be displayed as a list by disc standard. List display by standard is divided into standards such as BD (Blu-ray Disc), HD DVD (High Definition DVD), DVD-RW, DVD-RAM, DVD + RW / R, CD-RW, and CD-R. Refers to listing. Furthermore, after extracting the category (recorder) of the external device, the free space data of each recorder may be compared and the device group may be rearranged and displayed in a list in the order of large (or small) free space. The free space of the recorder and the standard name of the disc may be obtained by a method such as storing them in association with the conversion table or obtaining them directly from the external device using the CEC command.

  This makes it easy to use properly when moving or saving data. In the future, high-definition video will increase, but if you want to save it to a recorder, if you can identify the disc standard name at a glance, you can use it separately when saving high-definition video to the next-generation DVD and standard video to another DVD.

  Note that, as exemplified by the external device display name 61 and the external device display name 62 in FIG. 6, items belonging to the category such as the same recordable device may be displayed close to each other or can be used simultaneously by the same company. You may make it display the product (for example, a player and a recorder) close to each other.

  The external device display names 51 and 52 of the S company and the A company are “S company XX recorder 1”, “S company XX recorder 2”, “A company recorder 1”, and “A company recorder 2”. As illustrated, branch numbers may be attached in the case of the same external device display name. This can be realized by further changing the display name changing means to the external device display names with serial numbers when the display device is changed to the same external device display name for a plurality of input terminals. In the case of the same category with the same manufacturer name, for example, it is determined from the top part of the character string whether the same character string matches the desired number of characters (for example, 10 characters) and displayed in order from the top (for example, HDMI input terminal 1 is XX recorder 1 and HDMI input terminal 2 are XX recorder 2). When the character string in which the input terminal number is added as a branch number to the manufacturer name or model name is used, for example, in the case where the manufacturer name is English representing “S company”, “S company (1)”, “S company − 1 ”,“ S company 1 ”, etc., and when the model name is“ DV-ARW15 ”, the character string is changed to“ DV-ARW15 (2) ”,“ DV-ARW15-2 ”, etc. indicate.

  Although not shown, the input switching menus 40, 50, 60, etc. in FIGS. 4 to 6 are displayed relative to the position of the input terminal group provided in the television apparatus 1 by the switching menu display means. You may make it display on the position on the screen near. In recent large-sized televisions, once installed, it is difficult to understand where the external device connection terminal is located near the side (back) without looking into the side (back). However, by adopting such a display position of the input switching menu, the position where the input switching menu is displayed is relatively similar to the position of the actual external device connection terminal group. Become.

  As described above, by extracting the manufacturer name, model name, and category from the model information packet sent from the connected device and using it for the input display label, the details of the connected device and device are described. Make it easier to recognize. In other words, in the television device 1, it is possible to display which external device is the terminal that is input as an input source so that the user can be identified. Further, since the terminal display name is changed based on the model information packet transmitted simultaneously with the video packet, the external device to be changed is an external device that is not a video input source (for example, a repeater device such as the AV amplifier 2). Etc.) are automatically omitted, so that only the input source can be displayed.

  Next, with reference to FIG. 7, an example of a terminal display name change process when an external device is connected to and disconnected from an input terminal in the television apparatus to which the present invention is applied will be described.
