Description

  The present invention relates to a technology of a video display device that displays information on a device connected to an input terminal.

  Conventionally, in video display devices, names for identifying input terminals are prepared by default in video display devices, such as names such as “input 1” and “input 2” that are associated with each input terminal of video display devices by default. A method of selecting from names such as “DVD”, “video”, “video camera”, “game”, and the like has been taken. Further, the name candidates prepared by default could not be changed. Therefore, for example, when two game machines are connected to one video display device, there are two input terminals associated with the name “game”, and the connected input terminal must be confirmed. It was impossible to determine which game machine was connected to which input terminal.

Therefore, in Patent Document 1, the video display device includes device name information of an electronic device, and when the electronic device is connected to the input terminal, the video display device acquires the device name information of the electronic device. In the video display device, the acquired device name information and the device name information included in the video display device are collated, and when matching device name information is found, the matching device name information is displayed as the name of the connected electronic device. To do. If no matching device name information is found, input in text format is permitted, and the input name is displayed as the name of the electronic device. Moreover, in patent document 1, even if it is a case where the acquired apparatus name information and the apparatus name information with which an image display apparatus is provided, the input by a text format is permitted and the input name is made into the name of an electronic device. Display is possible. The name externally input in the text format is stored together with the identification information unique to the electronic device, and the stored device name is displayed even if the same electronic device is connected to another external terminal.

  << Embodiment 1 >> (Outline of Embodiment 1) Embodiment 1 will be described. FIG. 15 is described with reference to a conceptual diagram of features of the video display apparatus according to the present embodiment. In the video display device (1500) according to the present embodiment, at least one or more input terminals (1501 to 1504) are provided, and electronic devices (1505 to 1507) externally connected to the respective input terminals are identified as shown in FIG. In order to do this, each input terminal is associated with a device identification name (1509 to 1514). The association is performed when the user freely sets and sets a device identification name and an input terminal prepared in advance on a setting screen or the like. For example, the user can select an input terminal to be set on a screen displayed on the video display device illustrated in FIG. In FIG. 16A, an image on the back side of the video display device is displayed, and the positions where the input terminals are arranged are shown. When the user selects an input terminal to be set, a screen illustrated in FIG. 16B is displayed on the video display device. The user can select one of the plurality of device identification names illustrated in FIG. 16B and link the device identification name to the input terminal.

  When the user wants to display the video from the electronic device connected to the input terminal on the video display device, the device identification name (see FIG. 17) associated with the input terminal in the display switching menu of the electronic device shown in FIG. "DVD" (1509), "VHS" (1510), "game" (1511), or "CS" (1513)). Then, the video signal from the electronic device connected to the selected input terminal can be displayed on the display of the video display device. In addition, as in the case of the input terminal 4 (1504), even when an electronic device is not actually externally connected, an identifiable name of the electronic device to be externally connected is associated with the input terminal in advance. Is also possible. In FIG. 15, since a CS tuner (1508) is scheduled to be connected to the input terminal 4, a device identification name “CS” (1513) is associated with the input terminal 4 in advance. The above concept is common to other embodiments. In the present embodiment, a video display device that can change the device identification name to a user's favorite name by changing the device identification name and easily identify an externally connected electronic device will be described.

  (Configuration of Embodiment 1) FIG. 1 illustrates an example of a functional block diagram in this embodiment. The “video display device” (0100) of the present embodiment shown in FIG. 1 includes a “device identification name holding unit” (0101), a “device identification name display selection unit” (0102), and a “name change possibility determination unit”. (0103), a “name change information receiving unit” (0104), and a “rewriting unit” (0105).

  Each unit which is a component of the present invention is configured by hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, there are hardware configured by a CPU, a bus, a memory, an interface, a peripheral device, and the like, and software that can be executed on the hardware. As software, the functions of each unit are realized by sequentially executing a program developed on the memory, and processing, storing, and outputting data on the memory and data input through the interface. (The same applies throughout the specification.)

  (Description of Configuration of Embodiment 1) The “device identification name holding unit” (0101) has a function of associating and holding a plurality of device identification names to be displayed in association with input terminals and a name change enable / disable flag. . Specifically, the device identification name holding unit corresponds to a nonvolatile memory or the like provided in the video display device, and holds the device identification name by storing the device identification name in a storage area of the nonvolatile memory. The device identification name held in the device identification name holding unit is not lost even when the video display device is turned off. The device identification name holding unit desirably holds device identification names equal to or more than the number of input terminals in order to identify the input terminals.

  The “input terminal” is a terminal connected to input a video signal or an audio signal from an externally connected electronic device to the video display device. The video display apparatus according to this embodiment includes at least one or more input terminals.

  “Device identification name” refers to information indicating a name for allowing a user to identify an electronic device externally connected via an input terminal. It is generally difficult to identify what kind of electronic device is connected to the connected side, that is, the video display device side, simply by externally connecting the electronic device to the input terminal. Therefore, it is clarified in advance by associating the name of the externally connected electronic device (device identification name) and the input terminal of the video display device to which the electronic device is connected. It is assumed that the input terminal to which the electronic device is connected is made selectable by the name. By doing so, the user can select an input terminal as if selecting an electronic device, and can select an electronic device indirectly connected externally by the operation.

  When the user wants to execute screen display by a signal from an externally connected electronic device, by selecting any one device identification name from a list of a plurality of device identification names displayed on a menu or the like, The display of the video display device can be switched to an input signal from the corresponding electronic device. The selection is performed using, for example, a mouse which is a GUI (Graphical User Interface), a remote control keyboard, or the like.

  The device identification name is also displayed when displaying the video signal displayed on the display as a video signal externally input from an electronic device connected to which input terminal.

  A plurality of names are prepared as the device identification names, and one of the names is associated with one input terminal. Although it is possible to associate one name with a plurality of input terminals, in this case, it is difficult to identify the electronic device connected to each input terminal. It is desirable to be associated one-to-one. Since the device identification name is a name associated with the input terminal, the device identification name can be set without actually connecting the electronic device to the input terminal. Further, it is possible to use one input terminal by replacing a plurality of electronic devices. Even in this case, the device identification name associated with the input terminal does not change. Specifically, the device identification names include “video 1”, “video 2”, “component 1”, “component 2”, “D terminal”, “CATV”, “CS”, “DVD”, “game”. ”,“ Movie ”,“ D-VHS ”,“ HDD ”,“ DVR ”,“ BD ”,“ digital camera ”,“ input 1 ”,“ input 2 ”,“ INPUT 1 ”,“ INPUT 2 ”, etc. For example, names that do not depend on the connected device, such as “Daddy input terminal” and “My input terminal”, can also be used. These may be prepared in advance or all of them may be used by input from the user.

  The “name change enable / disable flag” is a flag indicating whether or not the device identification name can be changed. The name change enable / disable flag includes a name change enable flag and a name change disable flag, and one of the flags is associated with the device identification name. Specifically, the name change enable / disable flag is information indicating whether or not name change is possible. Information indicating whether or not the name can be changed is associated with information indicating the device identification name and stored in a storage area such as a non-volatile memory which is a device identification name holding unit. If a name changeable flag is associated with a certain device identification name, the device identification name can be changed. If a name change impossible flag is associated, the device identification name cannot be changed. . Which flag is associated with each device identification name may be associated in advance by default, or may be freely associated by the user. As in the conceptual diagram illustrated in FIG. 2A, the association between the device identification name and the selectability flag may be managed in a table. In this case, the table illustrated in FIG. 2A is held by the device identification name holding unit. The name change enable / disable flag may be implemented, for example, as a flag provided in a part of the memory in which the device identification name is stored. For example, the first 8 bytes may be used as the main body storage area for information indicating the device identification name, and the subsequent 1 bit may be used as the storage area for the name change enable / disable flag.

  The “device identification name display selection unit” (0102) has a function of displaying the device identification name on the display so that the user can select it.

  The user selection here means selecting a device identification name whose name is to be changed. That is, when the user feels that the device identification name is inappropriate, the user selects the device identification name in the device identification name display selection unit, and changes the selected device identification name.

  The user selects one name to be changed from the device identification names displayed on the display in the device identification name display selection unit. The “display” only needs to display a video signal or the like, such as a cathode ray tube display, a liquid crystal display, or a plasma display. “Display so as to be selectable by the user” means displaying the device identification name on the display so that the user can select the device identification name by operating the remote controller or the like. FIG. 2B shows a specific example when the device identification name is displayed on the display. The user can select one device identification name to be changed by operating a cross key such as a remote controller from a plurality of device identification names shown in FIG. In addition, you may display visually the associated name change possibility flag with an apparatus identification name. For example, in FIG. 2 (b), a device identification name marked with a circle on the left side is associated with a name changeable flag, and a device identification name marked with a cross is marked with a name change impossible flag. Indicates that it is associated.

  The “name change possibility determination unit” (0103) has a function of determining whether the device identification name selected by the device identification name display selection unit is associated with a name change enable flag. Specifically, when a device identification name is selected by the device identification name display selection unit, the name change possibility determination unit accesses a storage area in which information related to the device identification name is stored, and the selected device identification It is read whether the information about the name is stored together with the information indicating the name change enable flag or the information indicating the name change disable flag. When stored together with the information indicating the name change enable flag, the selected device identification name is determined as “name change possible”, and when stored together with the information indicating the name change disable flag, it is selected. The device identification name is determined to be “name cannot be changed”. The name change availability determination unit transmits the determination result to the name change information reception unit. The user can change the name of only the device identification name that is determined to be changeable.

  The “name change information accepting unit” (0104) has a function of accepting input of name change information when the result of the judgment by the name change availability judgment unit is that the name can be changed. Specifically, when the determination result in the name change enable / disable determining unit obtains a determination result that the name can be changed, a program stored in a storage area such as a nonvolatile memory is started, and the selected device identification name is set. Instead, it starts accepting input of name change information to be displayed. The name change information is input by selecting a character string based on a key operation on the activated program. The name change information received by the name change information receiving unit is stored in a temporary memory or the like.

  “Name change information” refers to information of a name to be displayed instead of the device identification name selected by the device identification name display selection unit. When the user does not include a favorite name in the device identification name prepared in advance, the user inputs the favorite name in the name change information, and changes the device identification name in the rewriting unit described later, A favorite name can be used as the name of the input terminal. At the stage of inputting the name change information, the name change information is only stored in a temporary memory provided in the video display device, and the device identification name held in the device identification name holding unit has not yet been rewritten. Since this is not done, the name change information is not reflected in the device identification name held by the device identification name holding unit.

  “Receiving input of name change information” means, for example, that a program stored in the storage area is started and 50-sound hiragana / katakana, alphanumeric characters, symbols, etc. are displayed on the display as shown in FIG. The user can input name change information by selecting these characters by operating the remote controller or the like. Although not shown in the figure, a program that displays an image imitating a personal computer keyboard on a display may be started and characters may be input as a simulated keyboard. The method may be used.

  The “rewriting unit” (0105) has a function of rewriting the selected device identification name held in the device identification name holding unit by the name change information received by the name change information receiving unit. When the name change information received by the name change information receiving unit is finalized, the rewriting unit holds the name change information in place of the selected device identification name held in the device identification name holding unit. Is written as a new device identification name. Specifically, the rewriting unit erases information related to the selected device identification name stored in a storage area such as a nonvolatile memory, and the name change information stored in the temporary memory by the name change information receiving unit. Is stored in the storage area as a new device identification name.

  (Processing Flow of First Embodiment) FIG. 4 shows a processing flow of a device identification name rewriting method according to the video display apparatus of the first embodiment. The device identification name rewriting method according to the video display device is such that a plurality of device identification names to be displayed in association with an input terminal and a plurality of device identification names stored in association with name change enable / disable flags in advance are displayed on a display. In such a way that the user can select (S0401, device identification name display step). The user selects one device identification name to be changed from the plurality of device identification names displayed in the device identification name display step (S0402, device identification name selection step). Next, the video display device determines whether or not the device identification name selected in the device identification name selection step is associated with a name change enable flag (S0403, name change enable / disable determination step). If the determination result in the name change permission determination step is a determination result that the name change is possible, the video display device receives input of name change information (S0404, name change information reception step). Next, the selected device identification name stored is rewritten by the name change information received in the name change information receiving step (S0405, rewriting step). If the determination result in the name change permission determination step (S0403) is a determination result that the name change is impossible, the user changes the name for another device identification name, so that the user can change the name. Make a selection. Through the above steps, the stored device identification name is rewritten.

  (Effect of Embodiment 1) The video display apparatus according to this embodiment can set different device identification names even when the same electronic device is connected to two different input terminals. Both can be identified.

  In addition, since the device identification name can be held in the device identification name holding unit in advance without connecting the electronic device to the input terminal, the device identification name is input every time the electronic device is connected. The user's troublesomeness can be reduced.

  << Embodiment 2 >> (Outline of Embodiment 2) Embodiment 2 will be described. The video display device according to the present embodiment is based on the video display device according to the first embodiment, and the input of the name change information is related to the video display device performed by software keyboard means.

  (Configuration of Second Embodiment) FIG. 5 illustrates an example of a functional block diagram in the present embodiment. The “video display device” (0500) of the present embodiment shown in FIG. 5 is based on the configuration of the first embodiment, and includes a “device identification name holding unit” (0501) and a “device identification name display selection unit” (0502). And a “name change enable / disable determining unit” (0503), a “name change information receiving unit” (0504), and a “rewriting unit” (0505). Since the above-described components have already been described, a description thereof will be omitted. Further, the “name change information receiving unit” (0504) has “software keyboard means” (0506), and the “software keyboard means” (0506) has “completion information output device” (0507). The “rewriting unit” (0505) includes “rewriting confirmation means” (0508).

  (Description of Configuration of Embodiment 2) “Software keyboard means” (0506) has a function of using a software keyboard for inputting name change information in the name change information receiving unit. Hereinafter, the software keyboard according to the present embodiment will be described in detail with reference to FIGS. When the device identification name selected by the user in the device identification name display selection unit is determined to be related to the name change enable flag by the name change enable / disable determination unit, the name change information reception unit Start accepting input. When the reception of the input of the name change information is started, the name change information receiving unit expands the software keyboard program stored in the storage area on the temporary memory and activates the software keyboard. Then, the interface of the software keyboard is displayed on the display, and the user is allowed to input to the software keyboard.

  FIG. 6A shows a state in which the software keyboard (0600) is activated when the device identification name associated with the changeable flag “INPUT1” is selected from the device identification names. The software keyboard includes a character mode (0601), a cursor (0602), an input field (0603), a character group (0604), a character mode scroll button (0605), a character group scroll button (0606), An input completion button (0607). The selection on the software keyboard and the movement of the cursor are performed with a cross key provided on the remote control. Hereinafter, a method for inputting characters using the software keyboard (0700) will be described with reference to FIG. In FIG. 7, for the sake of explanation, the description is made in a state where nothing is input in the input field (0703). First, the character mode is selected. The character mode includes modes such as “Hiragana”, “Katakana”, “alphanumeric full-width”, “alphanumeric half-width”, and “symbol half-width”. FIG. 7A shows a case where “alphanumeric full-width” is selected as the character mode (0701). If the character mode to be selected is not displayed, the character mode scroll button (0705) is selected to display the desired character mode. When the character mode is selected, a character group (0704) corresponding to the character mode is displayed. When the character group is displayed, the character to be input is selected from the displayed character group. For example, when inputting a double-byte alphanumeric character “B”, “ABC” is selected from the character group displayed in FIG. FIG. 7B shows a case where “ABC” is selected from the character group of FIG. In FIG. 7B, character groups from which characters such as “A”, “B”, “C”, “a”, “b”, and “c” can be selected are displayed. In FIG. 7B, by further selecting “B”, the full-width alphanumeric “B” is displayed in the input field (0703), and the cursor (0702) moves to the right by one character. If the character to be input is not displayed in the character group, the character group scroll button (0706) is selected to display the desired character. After inputting the desired character, the character input is completed by an input completion button (0707). The characters input in this manner are stored in the temporary memory by the name change information receiving unit as name change information. For example, when “Pleste” is input using a software keyboard, information representing the characters “Pleste” is stored in the temporary memory as name change information.

  As shown in FIG. 8, although not a mode for inputting characters, an “edit” mode is provided in the character mode (0801), and a button for editing characters is displayed in the character group (0804). Good. For example, when “to the left” is selected from the character group in the edit mode, the cursor (0802) in the input field (0803) moves to the left by one character. When “Right” is selected, the cursor in the input field moves to the right by one character. Selecting "Delete Character" deletes the character at the cursor position in the entry field. When “cancel input” is selected, the character input by the software keyboard (0800) is not accepted as the name change information by the name change information accepting unit, and the software keyboard ends. When “input complete” is selected, the characters input to the software keyboard are received as name change information by the name change information receiving unit, and the software keyboard is terminated.

  The “completion information output device” (0507) is a function of the software keyboard means, and is a device that outputs completion information to the rewriting unit by completing the input of the software keyboard. “Completing the input of the software keyboard” means that the input character is received as the name change information by the name change information receiving unit and the software keyboard is terminated. If the name change information is not received by the name change information receiving unit and the process is terminated, the input is not completed. The input of the software keyboard is completed by selecting the input completion button (0607) in FIG. 6A or by selecting “input completion” from the character group in the edit mode shown in FIG. 8 as described above. Can do.

  The “rewriting confirmation means” (0507) is a function of the rewriting unit, and is a function of confirming rewriting of the device identification name in the rewriting unit when the completion information output from the completion information output unit is acquired. When the rewriting of the device identification name in the rewriting unit is confirmed, the name change information entered on the software keyboard is reflected as a new device identification name instead of the selected device identification name held in the device identification name holding unit. Is done. As described above, when the name change information indicating the characters “Presute” is stored in the temporary memory, “Presute” is used instead of the device identification name “INPUT1” selected in FIG. Is displayed as the device identification name (FIG. 6B). When the changed device identification name is associated with the input terminal in the setting menu shown in FIG. 16B or the like, it is displayed as a name for identifying the externally connected electronic device in the video signal display switching menu shown in FIG. Is done.

  (Effect of Second Embodiment) In addition to the effects of the video display apparatus according to the first embodiment, the video display apparatus according to the second embodiment uses a software keyboard to input name change information, thereby identifying the input terminal identification name. In this change, user convenience can be improved.

  << Embodiment 3 >> (Outline of Embodiment 3) Embodiment 3 will be described. The video display device according to the present embodiment is the video display device according to any one of the first and second embodiments, and relates to a video display device in which the number of name changeable flags is smaller than the number of name change impossible flags. .

  (Configuration of Third Embodiment) The video display device according to the present embodiment is based on the video display device described in the first or second embodiment, and is associated with the device identification name held in the “device identification name holding unit”. The name change enable / disable flag is characterized in that the number of name change enable flags is smaller than the number of name change disable flags, or the number of name change enable flags is one.

  (Description of Configuration of Embodiment 3) “The number of name change enable flags is smaller than the number of name change disable flags” means that in the video display device in which the name change enable / disable flag is associated with the device identification name in advance. This indicates that the number of name changeable flags is smaller than the number of name change impossible flags, and the number of rewritable device identification names is smaller than the number of non-rewritable device identification names. By doing so, the number of device identification names that can be freely set by the user is reduced, but instead, a name that is highly likely to be selected is set by default in advance by the user. The number of device identification names can be reduced. Further, since the number of device identification names to be changed is limited, a storage area for storing the device identification names after the change can be saved.

  “The number of name changeable flags is one” means that the name changeable flag is associated with only one device identification name in the video display device in which the name changeability flag is associated with the device identification name in advance. This means that there is one rewritable device identification name. By having at least one device identification name that can be changed, the user can identify two similar electronic devices or the same electronic device. For example, like the video display device (0900) whose conceptual diagram is illustrated in FIG. 9, the game machine 1 “GC” (0906) is input terminal 1 (0901) and the game machine 2 “PS” is input terminal 2 (0902). When (0907) is externally connected and the device identification name “game” (0903) is associated with the input terminal 1 and the input terminal 2, the two game machines cannot be identified only with the device identification name. However, if there is at least one device identification name that can be changed, the user can change the device identification name so that two game machines can be identified. Therefore, the device identification name “INPUT1” (0904) associated with the changeable flag (0905, indicated by a circle in the figure) in FIG. 9 is changed, and the changed device identification name and the input terminal 2 are associated with each other. Thus, it is possible to identify two game machines.
