The video signal processing unit 41 also has a function of acquiring data for OSD (On Screen Display) processing such as menu display from the main control unit 30 and outputting the data to the display unit 43.

  The communication unit 50 includes a power line modem 51, a communication data processing unit 52, and a LAN unit 53. The LAN unit 53 performs communication by connecting to a communication network 22 such as a LAN (Local Area Network). The power line modem 51 is an adapter for performing PLC, and generates communication data by performing predetermined encoding processing and compression processing on data to be transmitted for communication according to a predetermined standard of PLC. Data is superimposed on the power line 21. Further, the power line modem 51 decodes and decompresses communication data of a predetermined PLC standard that is transmitted while being superimposed on the power line 21, and converts it into a signal in a format that can be used in the television 10. The communication data processing unit 52 generates data for communication via the power line modem 51 or the LAN unit 53, or converts the acquired data into a data format for processing in the television 10.

  The AV setting unit 60 includes a setting processing unit 61, a setting data storage unit 62, a master data storage unit 63, and a slave data storage unit 64.

  The setting processing unit 61 receives setting operations such as video adjustment and audio adjustment from the user, and reflects the received settings. Examples of image adjustment items include “backlight”, “contrast”, “brightness (luminance)”, “color temperature”, and “noise reduction processing (NR)”. Examples of the sound adjustment items include “high sound”, “low sound”, “balance”, “surround”, and the like. When there is a setting operation related to video adjustment or audio adjustment from the user, the setting processing unit 61 instructs the video signal processing unit 41 to display the setting screen in OSD via the main control unit 30. In addition, the setting processing unit 61 stores the setting by the user in the setting data storage unit 62. The setting processing unit 61 stores, as master data, setting data to be transmitted to the slave-side televisions (second to sixth televisions 10b to 10f) when functioning as the master-side television (first television 10a). Store in the unit 63. Further, when functioning as a slave-side television, the setting data acquired from the master-side television is reflected and stored in the slave data storage unit 64.

  Next, image adjustment using the setting screen will be described with reference to FIGS. FIG. 3 is an example of a screen for setting whether the television 10 is a master-side television or a slave-side television. The television 10 accepts a user's setting operation through OSD display. When the user selects the display of the setting screen by operating the remote controller 35 or the like, the setting processing unit 61 displays the setting screen C1 as illustrated on the display unit 43. Specifically, the upper area of the setting screen C1 is provided with a “large item” C10 as a belt-like area, and the “large item” C10 includes “main body setting” C11, “video adjustment” C12, “audio adjustment”. "C13" and "Group setting" C14 areas are provided so as to be selectable. In the figure, “group setting” C14 is selected, and the fact that it is selected is highlighted. Also, “middle item” C15 on the left side of the screen indicates what items are displayed.

  In the detailed setting area D10, the user can select “master” to function as the master-side television or “slave” to function as the slave-side television in the substantially central selection area D11. Here, a state where “master” is selected is shown. The user selects either “master” or “slave” and presses the “setting complete” button D12 arranged on the lower side. Whether the “master” or “slave” is selected is stored in the setting data storage unit 62.

  FIG. 4 is an example of a screen for adjusting the AV mode displayed when “Video adjustment” C12 is selected. In the detailed setting area D20, four of “Standard”, “Dynamic”, “Cinema”, and “Game” are displayed. For each type of AV mode, adjustment items of “backlight”, “contrast”, “brightness”, “sharpness”, “color temperature”, and “noise reduction processing” can be adjusted. The AV mode is a group of settings related to video adjustment and audio adjustment stored in advance according to the content to be played back. For example, when “Standard” is selected, the adjustment items for normal viewing by the user Is reflected on the television 10, and when “cinema” is selected, the value of the adjustment item suitably adjusted when the user views the movie content is reflected on the television 10.

  More specifically, in the mode selection area D21, it is possible to select which AV mode of “standard”, “dynamic”, “cinema”, and “game” is adjusted. Here, a state in which the third “cinema” mode is selected is shown. Furthermore, in the item adjustment area D22 below the mode selection area D21, adjustment items for “backlight”, “contrast”, “brightness”, “sharpness”, “color temperature”, and “noise reduction processing” can be adjusted. Here, “Backlight” is “0”, “Contrast” is “3”, “Brightness” is “−11”, “Sharpness” is “3”, “Color Temperature” is “Mid (Middle)”, “ “Noise reduction processing” is “off”. The user can set each adjustment item to a desired value by operating the remote controller 35. When the setting is completed, the user presses the “setting completed” button D23 to reflect the changed value and store it in the setting data storage unit 62.

  FIG. 5 shows a screen displayed to confirm whether or not to transmit video adjustment and audio adjustment setting data to the slave TV when the TV 10 functions as the master TV (first TV 10a). It is an example. This screen is displayed when the “master” functioning as the master TV is selected on the setting screen shown in FIG. 3, and when the “slave” functioning as the slave TV is selected. Do not show. When the “Yes” button D31 is pressed in the transmission confirmation area D30 of the illustrated screen, the communication data processing unit 52, the power line modem, and the second to sixth televisions 10b to 10f shown in FIG. Predetermined data processing is performed by 51, and setting data is transmitted via the power line 21. In the second to sixth televisions 10b to 10f, the data acquired by the power line modem 51 and the communication data processing unit 52 from the power line 21 is subjected to predetermined decoding processing and the like, and the setting processing unit 61 is connected via the main control unit 30. Will be notified. The setting processing unit 61 of the second to sixth televisions 10b to 10f reflects the setting data transmitted from the first television 10a in each AV mode. When the “No” button D32 is pressed, the setting data transmission process is not performed.

  Next, based on the flowchart of FIG. 6, the above-described transmission processing of setting data from the master-side television (first television 10a) to the slave-side televisions (second to sixth televisions 10b to 10f) is briefly summarized. I will explain.

  When the user changes the adjustment item of the AV mode on the setting screen shown in FIG. 4 and presses the “setting completed” button D23, first, the setting process of the AV mode is reflected on the television 10 (S10). . Next, the setting processing unit 61 refers to the setting data storage unit 62 and determines whether or not the television 10 is set as the master-side television (S11).

  When the television 10 is set as a slave-side television (N in S11), the setting data is not transmitted and the AV mode setting processing is completed, and the processing of this flowchart is completed. When the television 10 is set as the master-side television (Y in S11), the setting processing unit 61 displays the transmission confirmation screen shown in FIG. 5 (S12) and sends the changed setting data to the slave-side television. (S13).

  When it is selected that transmission is not performed by pressing the “No” button D32 (N in S13), the AV mode setting process ends. When transmission is selected by pressing the “Yes” button D31 (Y in S13), the setting processing unit 61 transmits setting data to the slave-side television via the communication data processing unit 52 and the power line modem 51. (S14) The AV mode setting process ends.

  Next, based on the flowchart of FIG. 7, the processing when the slave-side television (second to sixth televisions 10b to 10f) acquires setting data from the master-side television (first television 10a) is simplified. Explained.

  The communication data processing unit 52 of the second to sixth televisions 10b to 10f monitors whether or not setting data is transmitted from the master-side television (first television 10a) via the power line 21 (power line modem 51). If the setting data is not received (N in S21), the monitoring is involved (S20). When the setting data is received (Y in S21), the main control unit 30 acquires the setting data, and the setting processing unit 61 that has received the notification of the setting data transmits the setting data transmitted from the first television 10a. Is reflected in each AV mode (S22), and the processing according to this flowchart ends.

  In the present embodiment, the setting data transmitted from the master-side television (first television 10a) to the slave-side television is data relating to video adjustment. However, the present invention is not limited to this. For example, it may be data relating to audio adjustment or setting data relating to a brightness sensor (light sensor). Further, when the television 10 functions as a slave-side television, a setting operation for temporarily refusing reception of setting data of the master-side television from the user may be performed.

  According to the present embodiment, the AV mode setting data in the master-side television (first television 10a) can be transmitted to the slave-side televisions (second to sixth televisions 10b to 10f) by the PLC. As a result, it is not necessary to perform the setting process at the installation location of each television 10 as in the prior art, and the working time can be reduced.

  Moreover, since it is communication by PLC and both power supply and communication are covered with a power line, it can prevent that wiring becomes complicated. In addition, in the PLC, good communication is possible between the TVs 10 connected to the power line 21 extending from the same distribution board 20, but communication over the distribution board 20 is difficult because data becomes weak. . Using this feature, a plurality of televisions 10 connected to the power line 21 extending from the same distribution board 20 can be managed as one group.

  Also, by installing a general noise filter at a predetermined location on the power line 21, PLC communication beyond the noise filter cannot be performed. By utilizing the characteristics, group management becomes easy regardless of the distribution board 20. In hotels and the like, video adjustment of the television 10 may be required depending on the room environment. For example, a room on the first floor and a room on the tenth floor may have different room brightness. According to the present embodiment, the setting can be easily changed in units of floors with rooms.

<Second Embodiment>
In this embodiment, setting data is not transmitted from the master-side TV when changing the video adjustment, but the setting data to be transmitted is recorded in advance and the user selects it at a desired timing. Send. Since the configuration of the television 10 can be realized by the same configuration as that of the first embodiment (see FIG. 2), description of the configuration will be omitted, and a setting screen example and processing will be mainly described.

  FIG. 8 shows an example of a screen displayed when “video adjustment” C12 is selected on the television 10 of the present embodiment. The difference from the screen example of FIG. 4 is that a “memory” button D24 is provided. It is in. When the user presses the “store” button D24 after inputting a desired name in the setting name input area D25 instead of the “setting complete” button D23, the setting is not reflected, but the changed setting contents are set. The data is stored in the master data storage unit 63 by the unit 61. Here, the setting name “N2” is input to the setting name input area D25.

  FIG. 9 is an example of a screen displayed when setting data is transmitted from the master-side television to the slave-side television in the television 10 of the present embodiment. Unlike FIG. 5, here, the user first selects one setting data to be transmitted from the setting data displayed in the communication data selection area D33. In this screen example, five types of setting data of “current setting”, setting name “D1”, setting name “D2”, setting name “N1”, and setting name “N2” can be selected. , The setting name “D2” is selected. When the “Yes” button D31 is pressed, the selected setting data is transmitted from the master-side television to the slave-side television.

  As described above, according to the present embodiment, the same effect as that of the first embodiment can be obtained, and the setting data stored in the master-side television can be transmitted at any timing of the user. Processing such as sending different setting data or sending different setting data according to the weather can be performed by a simple operation. Also, the setting data transmitted to the slave-side television can be transmitted different from the setting data actually reflected on the master-side television.

<Third Embodiment>
The outline of this embodiment is that when a master-side television transmits setting data to a slave-side television, the slave-side television to be transmitted is managed by an ID (authentication number). Further, the contents of the setting data to be transmitted, specifically, not all the modes of the AV mode are transmitted, but the mode to be transmitted can be selected. In addition, the setting data to be transmitted can be compared between the master-side television and the slave-side television. Further, when the AV mode setting is changed on the slave-side television, the change is not performed for a predetermined period in order to give priority to the change. Details will be described below.

  FIG. 10 shows a network system 200 in which seven first to seventh televisions 10 a to 10 g are connected via a power line 21 extending from a distribution board 20. The first to seventh televisions 10a to 10g are equipped with a PLC adapter ("power line modem 51" described later) for performing PLC. IDs "201" to "207" are assigned to the first to seventh televisions 10a to 10g, respectively. The first television 10a and the seventh television 10g function as a master-side television, and the second to fifth televisions 10b to 10e function as slave-side televisions having the first television 10a as a master. Furthermore, the first to third televisions 10a to 10c are included in the “N” group, and the fourth to fifth televisions 10d to 10e are included in the “S” group. In addition, what kind of group is included can be arbitrarily set and changed. Since the first to seventh televisions 10a to 10g can be realized by the same configuration (see FIG. 2) as the television 10 of the first embodiment, description of the configuration is omitted, and setting screen examples and processing are mainly described. Will be described.

  FIG. 11 shows an example of a setting screen displayed when performing ID registration and group registration. The user inputs a desired ID in the ID registration area D41 of the setting area 40 in order to set the ID. For example, in the case of the television 10 installed in a hotel, management becomes easy by setting an ID corresponding to the room number. Here, the ID “201” is input. Next, the user performs group registration as necessary. When setting a group set in any of the televisions 10 connected to the network system 200, a desired group is selected by operating the group selection area D42. When a new group is registered, the user inputs a desired group name in the group registration area D43. When the group is not set, the group selection area D42 and the group registration area D43 are blank. Here, the group “S” is selected. When the input or selection of the ID and group is completed, the user presses a “setting complete” button D44. As a result, a desired ID and group are registered in the setting data storage unit 62.

  FIG. 12 is an example of a screen for setting the transmission target of setting data, that is, the target slave TV when set to the master TV (first TV 10a). The ID of the television 10 that is connected to the power line 21 and can communicate with the network system 200 is displayed so as to be selectable in the slave-side television selection area D51 in the setting area D50. When this screen is displayed, the setting processing unit 61 of the master-side television requests the slave-side television to transmit an ID. A television that is not set as a slave of a slave-side television or another master-side television notifies its own ID to the slave-side television that has requested transmission. Here, the televisions 10 (second to fifth televisions 10b to 10e) with IDs “202”, “203”, “204”, and “205” are selected as slave-side televisions, and the sixth television with ID “206” is selected. 10f is not selected. Therefore, when it is selected as shown in the figure, the first television 10a transmits the setting data described above to the second to fifth televisions 10b to 10e and does not transmit it to the sixth television 10f. More specifically, the setting data transmitted by the first TV 10a includes the ID of the target TV 10, and the slave TV that has acquired the setting data includes its own ID. Reflect the setting data acquired when

  FIG. 13 is an example of a screen for registering the master-side television (first television 10a) that is the transmission source of the setting data on the slave-side television (second to fifth televisions 10b to 10e). In the master-side television setting area D61, the ID of the master-side television that is connected to the power line 21 and can communicate with the network system 200 is displayed in a selectable manner. When this screen is displayed, the slave TV setting processing unit 61 requests the master TV (first and seventh TVs 10a and 10g) to transmit an ID. The setting processing unit 61 of the master-side television notifies the slave-side television that has requested transmission of its own ID. Here, the televisions 10 (10a, 10g) with IDs “201” and “207” are displayed as settable on the master side television, and the first television 10a with ID “201” is selected.

  FIG. 14 shows setting data of the slave-side television recorded in the master data storage unit 63 of the master-side television. As shown in the figure, the slave TV ID, group, change history, and settings for each AV mode are included. For example, in the television 10 with the ID “205” (fourth television 10d), it is recorded that the setting has been changed to “18:00 on January 1”. Before transmitting the setting data to the slave-side television, the master-side television first requests the master-side television for parameters and the like set in each mode of the AV mode and the change history. In response to the request, the slave-side television notifies the master-side television of the parameters set in itself and the change history.

  Next, transmission of setting data will be described. For example, FIG. 15 is a screen for selecting a setting data transmission destination (slave-side television) and a transmission AV mode. This screen is displayed when the AV mode setting change is completed on the setting screen described with reference to FIGS.

  In the transmission selection area D60 displayed in the upper part, first, the user selects whether to confirm the setting of the slave-side television. In the case of confirmation, the user presses a “Yes” button D61. When the “Yes” button D61 is pressed, the screen shifts to a screen described later with reference to FIG. If no particular confirmation is required, the user proceeds to the subsequent selection without pressing the “Yes” button D61 in FIG. In the transmission destination selection area D62 at the center of the transmission selection area D60, four IDs “202”, “203”, “204”, and “205” are displayed as IDs of the slave side television. Here, the group is displayed together with the ID. With regard to ID “205”, since the setting change by the user has been made most recently in the slave-side television (fifth television 10d), it is displayed that the setting change cannot be made from the master-side television.

  Next, the user selects a transmission mode from “standard”, “dynamic”, “cinema”, and “game” in the transmission mode selection area D63. Here, two modes, “dynamic” mode and “cinema mode”, are different from the set values of the master TV. Therefore, these two modes are selected as AV modes for transmission. Finally, when the user presses the “confirm” button D64, the setting data of the selected mode is transmitted to the selected slave television.

  FIG. 16 is a screen that is displayed when the “Yes” button D61 is pressed to confirm the setting of the slave TV on the screen of FIG. 15, and each set for the master TV and the slave TV. A mode in which the AV mode is compared and transmitted can be selected.

  As shown in the figure, in the setting data selection area D70, the setting contents of the AV mode of the master side TV are displayed in the upper master side setting contents display area D71, and the slave side setting contents display area D72 of the slave side TV are displayed. The AV mode settings are displayed. The user can select a transmission mode while comparing the display contents of the master-side setting content display area D71 and the slave-side setting content display area D72. The slave-side setting content display area D72 displays that the slave-side TVs with IDs “204” and “205” are displayed, and that the setting cannot be changed for the slave-side TV with the ID “205”. Yes. For the slave TV with ID “204”, “dynamic” mode and “cinema” mode are selected for transmission. When selection of the transmission mode is completed, the user presses a “Send” button D73 to transmit the setting data.

  Next, based on the flowchart of FIG. 17, the above processing when the setting is changed in the television 10 will be briefly described.

  When the setting of the AV mode to be transmitted is completed (S30), the setting processing unit 61 determines whether the television 10 is a master-side television or a slave-side television (S31). If it is a slave-side television (N in S31), the setting change history is recorded in the setting data storage unit 62 (S32), and the setting change is completed. In the case of the master-side television (Y in S31), the setting processing unit 61 of the master-side television acquires the setting data for changing the setting (slave-side television) and the AV mode setting content (S33). ), The setting contents of the master TV and the setting contents of the slave TV are displayed so as to be comparable (S34).

  Subsequently, the user selects a desired slave-side television as a setting data transmission destination, further selects an AV mode to be transmitted (S35), and when these selections are completed, the selected AV is selected for the selected slave-side television. The mode is transmitted as setting data (S36).

  According to the present embodiment, the same effects as those of the first and second embodiments can be obtained, and the master-side television and the slave-side television are managed by the ID, so that more detailed setting change is possible. Further, it is possible to adjust the AV mode whose setting is to be changed to the slave-side television while confirming on the master-side television. Also, only the AV mode whose settings should be changed can be reflected on the master-side television. In other words, the data currently set on the master TV is compared with the data to be set, and different difference data is transmitted, so the amount of data to be transmitted can be reduced and reflected. Can be shortened. In the embodiment, as shown in step S36, data is transmitted in units of AV mode. However, it is also possible to transmit different setting values (difference data) in units of items.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of these components, and such modifications are also within the scope of the present invention. For example, in the embodiment, the television is exemplified as the display device, but the above-described technique can also be provided for display devices such as a monitor, a DVD recorder, and an HDD recorder.
