[0011] Hereinafter, embodiments of the present technology will be described in the following order. 1. Content distribution system configuration 2. Display the picture quality adjustment menu 3. TV configuration and operation 4. Variations 5. Example of multiple specific streaming services

[0012] <Content distribution system configuration> FIG. 1 is a diagram illustrating an example of the configuration of a content distribution system according to an embodiment of the present technology.

[0013] The content distribution system in Fig. 1 is configured by connecting a TV 1 and distribution servers 2-1 to 2-N via a network 3 such as the Internet. A remote controller 4 is used to operate the TV 1. The remote controller 4 transmits commands to the TV 1 in response to buttons pressed by the user.

[0014] Communication between the TV 1 and the distribution servers 2-1 to 2-N is carried out via a network 3. The network 3 may be a wired network, a wireless network, or a network that combines wired and wireless networks. Hereinafter, when it is not necessary to distinguish between the distribution servers 2-1 to 2-N, they will be referred to as distribution servers 2.

[0015] A TV1, which is an image processing device, receives television broadcasts from broadcast stations (not shown), such as terrestrial digital broadcasts, satellite broadcasts, cable broadcasts, etc. Broadcast stations broadcast programs for each channel according to a predetermined schedule.

[0016] The TV 1 displays the images of the broadcasted programs on a display and outputs the audio from a speaker. For example, the display of the TV 1 has a so-called 4K resolution (3840 × 2160) pixels and is compatible with displaying HDR images.

[0017] Furthermore, the TV 1 has a function to receive not only programs provided by broadcasting but also content provided via the network 3. The content provided via the network 3 is provided, for example, by streaming. The content may also be provided by downloading.

[0018] When a predetermined distribution service is selected, for example, by operating the remote controller 4, the TV 1 displays the main screen of the distribution service on the display. The TV 1 is capable of using multiple distribution services provided by different operators.

[0019] The TV 1 receives and plays back the content transmitted from the distribution server 2. The TV 1 displays the video obtained by playing back the video data constituting the content on a display, and outputs the sound obtained by playing back the audio data from a speaker.

[0020] Distribution server 2 is a server that provides distribution services. Distribution server 2-1 is a server that provides distribution service A, and distribution server 2-2 is a server that provides distribution service B. Distribution server 2-N is a server that provides distribution service N.

[0021] One distribution service may be provided by one distribution server 2, or may be provided by multiple distribution servers 2. It is also possible for multiple distribution services to be provided by one distribution server 2.

[0022] In this way, a user of TV1 can select a desired distribution service from multiple distribution services and view content provided by the selected distribution service. TV1 is a device equipped with a general-purpose OS (Operating System), and applications for using each distribution service are installed.

[0023] FIG. 2 is a diagram showing an example of an application structure of the TV1.

[0024] The TV 1 is equipped with a TV OS 11. Various applications that run on the TV OS 11 are installed on the TV 1. In the example of Fig. 2, a TV viewing application 12-1, a search application 12-2, an image quality adjustment application 12-3, and content viewing applications 12-A to 12-N are shown.

[0025] The TV viewing application 12-1 is an application that manages the viewing of broadcast programs. While the TV viewing application 12-1 is running, the user can operate the remote controller 4 to select a predetermined channel and watch a program broadcast on the selected channel.

[0026] The search application 12-2 is an application that searches for information on the Web based on keywords input by the user by operating the remote controller 4 or by voice.

[0027] The image quality adjustment application 12-3 is an application that manages image quality adjustment of the display of the TV 1. When a user instructs the image quality adjustment application 12-3 to perform image quality adjustment, the image quality adjustment application 12-3 displays an image quality adjustment menu, which is a GUI (Graphical User Interface) for setting various items related to image quality.

[0028] The image quality adjustment application 12-3 sets image quality adjustment parameters for various items such as picture mode, brightness, color tone, etc. in response to user operations on the image quality adjustment menu. The image quality adjustment function and the image quality adjustment menu display function of the image quality adjustment application 12-3 may be provided as functions of the TV OS 11.

[0029] The content viewing application 12-A is an application for using the distribution service A provided by the distribution server 2-1.

[0030] For example, when content viewing application 12-A is started, the TV 1 displays the main screen of distribution service A based on information transmitted from distribution server 2-1. Information about available content, such as titles and thumbnail images, is displayed on the main screen, allowing the user to select desired content by viewing the information. When the user selects a desired content, distribution of the content begins.

[0031] The content viewing application 12-B is an application for using the distribution service B provided by the distribution server 2-2.

[0032] Although not shown in FIG. 2, dedicated applications for using other distribution services are installed on the TV 1.

[0033] In addition, applications installed on the TV 1 include a video application used to view recorded programs stored on an external recording medium such as an HDD (Hard Disk Drive), and a web browser used to display web pages.

[0034] For example, the TV viewing application 12-1, the search application 12-2, and the image quality adjustment application 12-3 are software provided by a manufacturer that manufactures and sells the TV 1. The content viewing applications 12-A to 12-N are software provided by businesses that provide the respective distribution services.

[0035] <Displaying the image quality adjustment menu> An example of the display of the picture quality adjustment menu will now be described. The display of the picture quality adjustment menu differs depending on whether content from a specific distribution service is being viewed or not.

[0036] In the following, it is assumed that distribution service A provided by distribution server 2-1 is a specific distribution service.

[0037] Example of watching a program FIG. 3 is a diagram showing an example of a picture quality adjustment menu displayed while a program is being viewed.

[0038] The soccer broadcast program shown in the upper part of Fig. 3 is, for example, a recorded program. That is, the screen shown in the upper part of Fig. 3 is a screen in which a video application used to watch the recorded program is running. The recorded program selected by the user is played by the video application, and the video is displayed on the display.

[0039] When an instruction to adjust the picture quality is given while the screen shown in the upper part of Fig. 3 is displayed, picture quality adjustment menu 51 is displayed on the right edge of the screen, as indicated by the arrow. The video of the recorded program continues to be displayed on the entire screen except for the display area of ​​picture quality adjustment menu 51.

[0040] FIG. 4 is an enlarged view of the image quality adjustment menu 51 of FIG.

[0041] 4, items related to adjusting image quality are displayed vertically in image quality adjustment menu 51. The dashed lines indicating the boundaries of the display areas for each item are not actually displayed on image quality adjustment menu 51.

[0042] The words "Picture adjustments" indicating the picture quality adjustment menu are displayed in the upper area 61 of the picture quality adjustment menu 51, and "Apps (Video)" is displayed below that. "Apps (Video)" indicates that the currently running application is a video application.

[0043] In this way, information indicating the running application is displayed in the area 61. For example, when the TV viewing application 12-1 is running and a broadcast program is being viewed, "Apps (Tuner)" is displayed, indicating that the TV viewing application 12-1 is running.

[0044] Areas 62 to 67 are formed in this order below area 61. Items related to image quality adjustment are assigned to areas 62 to 67. The user can operate the remote controller 4 to select a desired item and change the settings of the selected item.

[0045] Area 62 is an area used to set the Picture mode. The Picture mode is an overall image quality adjustment mode. In the example of FIG. 4, "Standard" is set.

[0046] For example, when the Picture mode item is selected, as shown in Fig. 5, a Picture mode selection menu 51A is displayed instead of the image quality adjustment menu 51. In the example of Fig. 5, "Vivid," "Standard," and "Cinema" are displayed as setting values ​​for Picture mode. The user operates the remote controller 4 to select a desired setting value from the setting values ​​displayed on the selection menu 51A.

[0047] Returning to the explanation of Fig. 4, an area 63 is an area used to set the Auto picture mode. The Auto picture mode is a function that automatically switches the picture quality in conjunction with the content being viewed. A switch 63A indicating whether Auto picture mode is on or off is displayed in area 63. The user can select the Auto picture mode item and change the on / off setting of Auto picture mode. Here, the on / off setting of Auto picture mode is displayed in area 63, but it is also possible to display and select "Auto picture mode" together with "Vivid," "Standard," and "Cinema" as setting values ​​for Picture mode.

[0048] Area 64 is an area used to set the brightness. Brightness represents brightness (luminance). In the example of FIG. 4, the setting value is set to "Max." The user can select the Brightness item and change the brightness setting.

[0049] Area 65 is an area used to set Color. Color represents the color tone. In the example of FIG. 4, a setting value of "60" is set. The user can select the Color item and change the color tone setting.

[0050] Area 66 is an area used for setting the Light sensor. The Light sensor is a function that automatically adjusts the screen brightness according to the ambient brightness. Area 66 displays a switch 66A that indicates whether the Light sensor is on or off.

[0051] The user can select the Light sensor item and change the on / off setting of the Light sensor function. In the example of Fig. 4, the Light sensor function is turned on, and the switch 66A is displayed in a bright color. The hatched area indicates that the switch 66A is displayed in a bright color.

[0052] Area 67 is an area used for detailed settings. The user can select an item of detailed settings and change multiple detailed settings related to image quality.

[0053] While watching a recorded program or a broadcast program, the picture quality is adjusted using the picture quality adjustment menu 51 as described above.

[0054] The same picture quality adjustment menu 51 is used to adjust the picture quality while viewing content provided by a distribution service other than distribution service A, which is a specific distribution service.

[0055] For example, when an instruction to adjust the image quality is given while viewing content provided by distribution service B, the area 61 displays, for example, "Service B app," indicating that the running application is content viewing application 12-B. When an instruction to adjust the image quality is given while viewing content provided by distribution service N, the area 61 displays, for example, "Service N app," indicating that the running application is content viewing application 12-N.

[0056] -Example of when watching content from a specific streaming service FIG. 6 shows an example of a picture quality adjustment menu displayed while viewing content from distribution service A.

[0057] 6 is, for example, a movie provided by distribution service A. The content selected by the user is played back by content viewing application 12-A, and the video of the content is displayed on the display.

[0058] 6, when an instruction to adjust the image quality is given, image quality adjustment menu 51 is displayed on the right edge of the screen, as indicated by the arrow. The content image continues to be displayed in the area of ​​the entire screen other than the area where image quality adjustment menu 51 is displayed.

[0059] FIG. 7 is an enlarged view of the image quality adjustment menu 51 in FIG.

[0060] Among the displays of the image quality adjustment menu 51 shown in Fig. 7, the same displays as those explained with reference to Fig. 4 are given the same reference numerals, and duplicated explanations will be omitted as appropriate.

[0061] As shown in FIG. 7, the area 61 displays "Service A app," which indicates that the running application is the content viewing application 12-A.

[0062] 7, area 63 is an area used to set the Service A calibrated mode. That is, area 63 becomes the Service A calibrated mode area instead of the Auto picture mode area. Area 63 displays a switch 63B that indicates whether the Service A calibrated mode is on or off.

[0063] Service A calibrated mode is an image quality adjustment mode for distribution service A.

[0064] When Service A calibrated mode is on, image quality adjustment of content from distribution service A is performed according to image quality adjustment parameters set for distribution service A. For example, image quality adjustment in Service A calibrated mode is performed using image quality adjustment parameters that are common to all content distributed by distribution service A.

[0065] The image quality adjustment parameters for distribution service A are set in advance and managed by the content viewing application 12-A. The image quality adjustment parameters for distribution service A may be acquired from the distribution server 2-1 when Service A calibrated mode is set to ON.

[0066] On the other hand, when Service A calibrated mode is off, picture quality adjustment of content from distribution service A is performed according to picture quality adjustment parameters set by the user using other display areas, including Picture mode. Picture mode can be used not only to adjust the picture quality of programs and content from distribution services other than distribution service A, but also to adjust the picture quality of content from distribution service A when Service A calibrated mode is off.

[0067] In the example of Fig. 7, Service A calibrated mode is set to off. For example, the default setting for Service A calibrated mode is off.

[0068] The items in the other areas are the same as those described with reference to FIG.

[0069] 7, the Brightness setting of the area 64 is set to "35," and the Color setting of the area 65 is set to "50." In addition, the Light sensor setting of the area 66 is set to off.

[0070] FIG. 8 is a diagram showing an example of the display of the image quality adjustment menu 51. As shown in FIG.

[0071] When Service A calibrated mode is set to on, area 62 is displayed grayed out to indicate that it is in an inoperable state. In other words, changing the Picture mode setting is prohibited. As an image quality adjustment mode, the setting of Service A calibrated mode takes priority over the setting of Picture mode.

[0072] In the example of FIG. 8, the switch 63B in the area 63 is turned on, and the switch 63B is displayed in a conspicuous color.

[0073] FIG. 9 is a diagram showing an example of the display of the image quality adjustment menu 51 when Service A calibrated mode is set to ON.

[0074] When Service A calibrated mode is set to on, Picture mode is displayed grayed out, as shown in the upper part of Fig. 9. In this state, if the user operates the remote controller 4 to select the Picture mode area 62, a message 91 is displayed, as indicated by the arrow, notifying that changing the Picture mode is prohibited.

[0075] When the user wants to change the picture mode, he or she switches the setting for Service A calibrated mode off, and then changes the picture mode.

[0076] Returning to the explanation of Fig. 8, the Brightness setting in area 64 is set to "40," and the Color setting in area 65 is set to "70." These Brightness and Color settings are based on the image quality adjustment parameters for distribution service A. Other items included in the detailed settings are also set appropriately based on the image quality adjustment parameters for distribution service A.

[0077] Even when Service A calibrated mode is set to on, items other than Picture mode are displayed in an operable state. The user can change the settings of items other than Picture mode.

[0078] In this way, the TV 1 is provided with a Service A calibrated mode, which is an image quality adjustment mode for the distribution service A.

[0079] The image quality adjustment parameters in the calibrated mode of Service A are, for example, parameters prepared by the operator of distribution service A. For the content of distribution service A, image quality adjustment will be performed in accordance with the intentions of the operator of distribution service A.

[0080] The operator of distribution service A can enable the user to view a video with the intended image quality on the operator's side.

[0081] As a user, one can also view the video of the content with the intended image quality on the operator's side.

[0082] The processing of TV1 for performing image quality adjustment as described above will be described later by referring to a flowchart.

[0083] <TV Configuration and Operation> · TV Configuration FIG. 10 is a block diagram showing an example of the hardware configuration of TV1.

[0084] The tuner 101 receives a broadcast wave signal supplied from an antenna (not shown) or a broadcast wave signal supplied from a set-top box for satellite broadcasting or cable TV, and extracts the signal of the channel selected by the user. The tuner 101 performs various processes such as A / D conversion and demodulation on the extracted signal, and outputs the program data obtained by performing the various processes to the decoder 102.

[0085] The decoder 102 decodes the video stream constituting the program data, and outputs the data of each picture obtained by the decoding to the signal processing unit 103. Also, the decoder 102 decodes the audio stream constituting the program data, and outputs the audio data of the program to the signal processing unit 103.

[0086] When playing back content from a predetermined distribution service, the decoder 102 decodes the video stream and audio stream of the content received by the communication unit 111 and supplied via the bus 106. The decoder 102 outputs to the signal processing unit 103 the data of each picture obtained by decoding the video stream of the content and the sound data obtained by decoding the audio stream.

[0087] The signal processing unit 103 adjusts the image quality of each picture supplied from the decoder 102 under the control of the CPU 107. The signal processing unit 103 outputs the picture after the image quality adjustment to the display 104, and displays the video of the program or content.

[0088] Furthermore, the signal processing unit 103 performs D / A conversion and the like on the audio data supplied from the decoder 102, and outputs the audio of the program or content from the speaker 105 in synchronization with the video.

[0089] The display 104 has 4K resolution pixels and is compatible with displaying HDR video. The display 104 is configured by an LCD (Liquid Crystal Display), an organic EL display, or the like.

[0090] A CPU (Central Processing Unit) 107, a ROM (Read Only Memory) 108, and a RAM (Random Access Memory) 109 are connected to one another via a bus 106. The CPU 107 executes programs stored in the ROM 108 or a storage unit 110 using the RAM 109, and controls the entire TV 1.

[0091] The recording unit 110 is configured by a recording medium such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), etc. The recording unit 110 records various data such as program data, content, EPG data, and programs.

[0092] The communication unit 111 is an interface to the network 3. The communication unit 111 communicates with the distribution server 2.

[0093] The operation I / F unit 112 receives commands sent from the remote controller 4 and outputs them to the CPU 107 via the bus 106 .

[0094] FIG. 11 is a block diagram showing an example of the functional configuration of the TV 1. As shown in FIG.

[0095] As shown in FIG. 11, in the TV 1, a content playback control unit 121, an image quality adjustment control unit 122, and a menu display control unit 123 are realized.

[0096] At least some of the functional units shown in Fig. 11 are realized by the CPU 107 in Fig. 10 executing a predetermined program. For example, the content playback control unit 121 is realized by the content viewing application 12-A being executed. The image quality adjustment control unit 122 and the menu display control unit 123 are realized by the image quality adjustment application 12-3 being executed.

[0097] The content playback control unit 121 controls the communication unit 111 to communicate with the distribution server 2-1 and requests the distribution server 2-1 to transmit the content selected by the user. The content playback control unit 121 controls the decoder 102 to play back the content transmitted from the distribution server 2-1.

[0098] The image quality adjustment control unit 122 controls the image quality adjustment of programs and content performed in the signal processing unit 103 .

[0099] For example, when playing back content from a specific distribution service, distribution service A, and Service A calibrated mode is set to on, the image quality adjustment control unit 122 performs image quality adjustment in accordance with image quality adjustment parameters for distribution service A. The image quality adjustment parameters for distribution service A are configured, for example, by a set of multiple parameters representing setting values ​​for multiple items.

[0100] Furthermore, when a program is played back or when content from a distribution service other than distribution service A is played back, image quality adjustment control unit 122 performs image quality adjustment in accordance with image quality adjustment parameters individually set by the user.

[0101] When an instruction to perform image quality adjustment is given, menu display control unit 123 displays an image quality adjustment menu on display 104. Furthermore, menu display control unit 123 switches the display of the image quality adjustment menu in response to a user operation as described above.

[0102] TV operation Here, the image quality adjustment process of the TV 1 will be described with reference to the flowchart of FIG.

[0103] The process of FIG. 12 is started, for example, when a user instructs that image quality adjustment be performed.

[0104] In step S1, menu display control unit 123 determines whether or not content of distribution service A, which is a specific distribution service, is currently being viewed.

[0105] If it is determined in step S1 that content from distribution service A is being viewed, then in step S2, menu display control unit 123 displays an image quality adjustment menu (FIG. 7) including an item for Service A calibrated mode, which is an image quality adjustment mode for distribution service A.

[0106] In step S3, menu display control section 123 switches the display of the image quality adjustment menu in accordance with the user's operation as described above.

[0107] In step S4, menu display control unit 123 determines whether or not to close the image quality adjustment menu. If the image quality adjustment menu is closed, the process returns to step S3, and the image quality adjustment menu continues to be displayed, until it is determined in step S4 that the image quality adjustment menu has been closed.

[0108] If it is determined in step S4 that the image quality adjustment menu is to be closed, then in step S5, the image quality adjustment control unit 122 controls the image quality adjustment of the content of distribution service A and displays the video after the image quality adjustment. For example, if Service A calibrated mode is set to on using the image quality adjustment menu, the image quality adjustment control unit 122 performs image quality adjustment in accordance with the image quality adjustment parameters for distribution service A.

[0109] On the other hand, if it is determined in step S1 that content from distribution service A is not being viewed, then in step S6, menu display control unit 123 displays the normal image quality adjustment menu (FIG. 4). The image quality adjustment menu displayed here does not include an item for Service A calibrated mode.

[0110] In step S7, menu display control unit 123 switches the display of the normal image quality adjustment menu in response to a user operation.

[0111] In step S8, menu display control unit 123 determines whether or not to close the normal image quality adjustment menu. Until it is determined in step S8 that the normal image quality adjustment menu has been closed, the process returns to step S7, and the normal image quality adjustment menu continues to be displayed.

[0112] If it is determined in step S8 that the normal image quality adjustment menu is to be closed, in step S9, the image quality adjustment control unit 122 controls the image quality adjustment of the program or content according to the user's settings, and displays the image after the image quality adjustment.

[0113] After the image quality adjustment is performed in step S5 or step S9, the process ends.

[0114] Through the above process, the provider of distribution service A can allow users to view video with the image quality that the provider intended. In addition, users can view content video with the image quality that the provider intended.

[0115] The content distributed by distribution service A may be content containing SDR video or content containing HDR video. 2 ), whereas the maximum brightness of HDR images exceeds that, for example, 10,000 nits.

[0116] If the display 104 of the TV 1 is a display capable of displaying HDR video as described above, the wide range of adjustments available means that the user may adjust the picture quality differently from what the provider intended. Providing a Service A calibrated mode, which is a picture quality adjustment mode for distribution service A, is considered to be particularly effective when displaying content containing HDR video.

[0117] <Modification> Example of image quality adjustment parameter settings Although the image quality adjustment parameters used when Service A calibrated mode is set to ON are assumed to be common to all content distributed by distribution service A, they may be prepared for each content. In this case, the image quality adjustment parameters are prepared, for example, by the content creator and managed by distribution server 2-1.

[0118] With reference to the flowchart in FIG. 13, the image quality adjustment process when image quality adjustment parameters are prepared for each content will be described.

[0119] The process of FIG. 13 starts when, for example, Service A calibrated mode is set to ON.

[0120] In step S21, the picture quality adjustment control unit 122 communicates with the distribution server 2-1, which is a server for a specific distribution service, and acquires picture quality adjustment parameters for the content to be played back.

[0121] In step S22, the image quality adjustment control unit 122 causes the signal processing unit 103 to adjust the image quality of the content in accordance with the image quality adjustment parameters acquired from the distribution server 2-1.

[0122] This allows the creator of the content distributed by distribution service A to allow users to view video with the image quality that the creator intended.

[0123] Image quality adjustment parameters may be prepared for each genre of content distributed by distribution service A, or for each model of TV 1. Also, image quality adjustment parameters may be prepared for each display capability of display 104 of TV 1.

[0124] Device Examples The image quality adjustment by the TV 1 as described above may be performed by a playback device 201 shown in A of Fig. 14 or a mobile terminal 202 shown in B of Fig. 14. The playback device 201 is a device that supports playback of predetermined packaged media, such as a set-top box.

[0125] For example, when Service A calibrated mode is set to ON, the playback device 201 adjusts the image quality of the content based on the image quality adjustment parameters for distribution service A, and outputs the image after the image quality adjustment to the TV 1 for display.

[0126] Other examples Although the parameters used for adjusting image quality are prepared as parameters for a specific distribution service, parameters used for adjusting the sound quality of the audio of the content may also be prepared.

[0127] When Service A calibrated mode is set to ON, TV1 adjusts the audio of the content based on the parameters for distribution service A and outputs the audio after the sound quality adjustment.

[0128] <Example when there are multiple specific streaming services> Although the case where the specific distribution service is distribution service A has been described, a plurality of distribution services may be provided as the specific distribution service.

[0129] In this case, the user can use the same image quality adjustment function as the Service A calibrated mode described above when viewing content from not only distribution service A, but also other distribution services such as distribution service B and distribution service C.

[0130] FIG. 15 is a diagram showing an example of providing image quality adjustment parameters.

[0131] When the content viewing application 12-A is running on the TV1, communication takes place between the content viewing application 12-A and the distribution server 2-1, and as shown by arrow #1, the distribution server 2-1 provides the content viewing application 12-A with image quality adjustment parameters for distribution service A.

[0132] The image quality adjustment parameters may be provided when Service A calibrated mode is set to on as described above, or at any other timing, such as when content distribution begins.

[0133] When Service A calibrated mode is set to ON, the image quality of the content of distribution service A is adjusted based on the image quality adjustment parameters provided by distribution server 2-1. The acquisition of the image quality adjustment parameters and the image quality adjustment based on the image quality adjustment parameters are performed by, for example, image quality adjustment control unit 122.

[0134] Such image quality adjustment parameters are also provided by a distribution server that manages the provision of other distribution services.

[0135] FIG. 16 is a diagram showing another example of providing image quality adjustment parameters.

[0136] For example, if a picture quality adjustment mode for distribution service B is prepared, picture quality adjustment parameters used in the picture quality adjustment mode for distribution service B are provided by distribution server 2-2 that manages the provision of distribution service B.

[0137] That is, communication takes place between the content viewing application 12-B (FIG. 2) running on TV1 and the distribution server 2-2, and as shown by arrow #2, the distribution server 2-2 provides the content viewing application 12-B with image quality adjustment parameters for distribution service B.

[0138] The image quality adjustment parameters for distribution service B are also provided at an arbitrary timing, such as when the image quality adjustment mode for distribution service B is set to ON or when distribution of content begins.

[0139] When the picture quality adjustment mode for distribution service B is set to ON, picture quality adjustment of the content of distribution service B is performed based on the picture quality adjustment parameters provided by distribution server 2-2.

[0140] In this way, when picture quality adjustment modes for a plurality of distribution services are prepared, the picture quality adjustment menu displayed will be different from the picture quality adjustment menu 51 described with reference to FIG. 8 and the like.

[0141] About the screen display FIG. 17 is a diagram showing an example of a display of the image quality adjustment menu.

[0142] When an instruction to adjust the picture quality is given while viewing content from distribution service A, picture quality adjustment menu 301 is displayed on the right edge of the screen, as shown in the upper part of Fig. 17. In the area of ​​the entire screen other than the display area of ​​picture quality adjustment menu 301, the video of the content from distribution service A continues to be displayed.

[0143] The image quality adjustment menu 301 displays the same items as those in the above-described image quality adjustment menu 51, arranged vertically. Duplicate descriptions will be omitted where appropriate.

[0144] FIG. 18 is an enlarged view of the image quality adjustment menu 301 in FIG.

[0145] The top area 301A is an area that displays information indicating the type of input (input type) to the display 104. In the example of Fig. 18, the input type is "Partner App".

[0146] "Partner App" indicates that an application for using a distribution service that has a dedicated image quality adjustment mode is being executed, and the video acquired by that application is being displayed on display 104.

[0147] The providers of distribution service A and distribution service B, etc., that have dedicated image quality adjustment modes are referred to as "Partners." Hereinafter, the image quality adjustment modes dedicated to "Partners" will be referred to as "Partner calibrated modes" where appropriate.

[0148] Areas 311 to 316 below area 301A are areas used for user operations. Items related to image quality adjustment are assigned to the areas 311 to 316. The user can operate the remote controller 4 to select a predetermined item and change the settings of the selected item.

[0149] An area 311 is an area used to set the Picture mode. In the example of Fig. 18, "Standard" is set as the Picture mode.

[0150] Area 312 is an area used to set the Auto picture mode.

[0151] The displays of the areas 311 and 312 are the same as the displays of the areas 62 and 63, respectively, which have been described with reference to FIG. 4, for example.

[0152] Area 313 is an area used to set Partner calibrated mode, which is an image quality adjustment mode exclusive to "Partner." Since content from distribution service A is currently being viewed, the words "Partner calibrated mode for Service A" are displayed in area 313 in Fig. 18. "Partner calibrated mode for Service A" is the Partner calibrated mode for distribution service A, i.e., the same as the Service A calibrated mode described above.

[0153] In the example of FIG. 18, the Partner calibrated mode setting is turned off. The default Partner calibrated mode setting is off, for example.

[0154] When the user operates the remote controller 4 to select the area 313, it becomes possible to select ON / OFF of the Partner calibrated mode.

[0155] An area 314 is used to set the brightness as an image quality adjustment parameter. In the example of Fig. 18, the setting value is set to "35".

[0156] Area 315 is an area used to set Color as an image quality adjustment parameter. In the example of Fig. 18, a setting value of "60" is set.

[0157] The displays of areas 314 and 315 are the same as the displays of areas 64 and 65, respectively, described with reference to Fig. 8. When Partner calibrated mode is off, the user can arbitrarily set the image quality adjustment parameters of Brightness and Color.

[0158] Area 316 is an area used to set the Partner Offset. The Partner Offset is an offset used for image quality adjustment when Partner calibrated mode is set to ON. Using the offset value set as the Partner Offset, further adjustments are made to the image quality adjustment made by the image quality adjustment parameters set in Partner calibrated mode.

[0159] In other words, by setting the Partner Offset, the user can view video that has been fine-tuned to suit their own preferences, rather than the original video in Partner calibrated mode (video whose image quality has been adjusted using the image quality adjustment parameters provided by the distribution service).

[0160] 18, when Partner calibrated mode is set to OFF, the area 316 is displayed in gray out. In this case, Partner Offset cannot be set.

[0161] 18, the coloring of the area 316 indicates that the area 316 is displayed in a grayed-out state. The areas 311 to 315 that are not grayed out are areas that the user can operate.

[0162] Using this display of picture quality adjustment menu 301, the user can adjust the picture quality of the content of distribution service A.

[0163] Returning to the explanation of Fig. 17, when Partner calibrated mode (Partner calibrated mode for Service A) is set to ON, as indicated by the tip of arrow #11, the content image is switched to image after image quality adjustment in Partner calibrated mode. Image quality adjustment is performed on the content using parameters provided by distribution service A as image quality adjustment parameters such as Brightness and Color. In the example of Fig. 17, the setting values ​​of "60" for Brightness and "50" for Color are used as image quality adjustment parameters in Partner calibrated mode.

[0164] In the image quality adjustment menu 301, of the areas 311 to 316, only the Partner calibrated mode area 313 and the Partner Offset area 316 are operable, and the other areas are displayed grayed out.

[0165] 17, the Partner calibrated mode setting in area 313 is on. The Picture mode setting in area 311 is "Partner calibrated," which indicates that the Partner calibrated mode takes priority.

[0166] In this state, if Partner calibrated mode is set to OFF, the content image is switched to an image that has not been subjected to image quality adjustment using Partner calibrated mode, as indicated by the tip of arrow #12. The display of image quality adjustment menu 301 also returns to the display it had when Partner calibrated mode was OFF, before it was set to ON.

[0167] FIG. 19 is a diagram showing a display example when setting the Partner Offset.

[0168] 19, when Partner calibrated mode is on, and setting Partner Offset in the bottom row of image quality adjustment menu 301 is selected, Offset menu 302 is displayed in place of image quality adjustment menu 301, as indicated by the tip of arrow #13. Offset menu 302 is a display used to set Partner Offset.

[0169] FIG. 20 is an enlarged view of the Offset menu 302.

[0170] The top area 302A displays the words "Partner Offset (Service A)," which indicates that the Offset menu 302 is a menu used to set the Partner Offset.

[0171] Areas 331 and 332 below area 302A are areas used for user operations.

[0172] In the example of Fig. 20, an area 331 is an area used to set the offset value of brightness, and an area 332 is an area used to set the offset value of color.

[0173] The user can set the Brightness Offset value by selecting area 331. The user can also set the Color Offset value by selecting area 332.

[0174] The offset value is set using options that use a relative expression to a reference, such as selecting one of five levels or selecting one of +5 / +3 / -3 / -5 levels.

[0175] In other words, the units of the offset value are different from the units of adjustment parameters such as brightness, color, etc. Absolute numerical values ​​such as the values ​​representing brightness and color ("35" and "60" in FIG. 18) are not used as the offset value.

[0176] For example, if "+5" is selected as the Brightness Offset value, a predetermined value corresponding to "+5" is added to the Brightness of "60" defined by the Partner calibrated mode, and the resulting value is used to adjust the Brightness.

[0177] After the offset value has been set, the display returns to the state shown in the upper part of FIG. 19, where the image quality adjustment menu 301 is displayed.

[0178] 19, there are two offset values ​​that can be set using the offset menu 302: a brightness offset value and a color offset value. However, the number of items displayed in the offset menu 302 varies depending on the partner calibrated mode. For example, in the partner calibrated mode for distribution service B (partner calibrated mode for service B), it may be possible to set offset values ​​for even more types of image quality adjustment parameters.

[0179] Even while viewing content from distribution service B, various settings related to image quality adjustments, including settings for Partner calibrated mode, are made using displays similar to those described above.

[0180] FIG. 21 shows an example of a screen display for each distribution service.

[0181] 21 shows the above-mentioned screen display when the content viewing application 12-A is launched and content from distribution service A is being viewed. The top row shows the display when Partner calibrated mode for Service A is off, and the middle row shows the display when Partner calibrated mode for Service A is on. The bottom row shows the display of Offset menu 302.

[0182] 21 shows the screen display when the content viewing application 12-B is started and content from distribution service B is being viewed. The top row shows the display when Partner calibrated mode for Service B is off, and the middle row shows the display when Partner calibrated mode for Service B is on. The bottom row shows the display of Offset menu 302.

[0183] As indicated by arrow #21, the input type displayed in the image quality adjustment menu 301 is "Partner App" whether the content viewing application 12-A or the content viewing application 12-B is running.

[0184] As indicated by arrows #22 and #24, the Picture mode display in the image quality adjustment menu 301 is the same whether the content viewing application 12-A or 12-B is running. When Partner calibrated mode is off, a setting value such as "Standard" indicating the user's selection is displayed (arrow #22), and when Partner calibrated mode is on, "Partner calibrated" indicating that Partner calibrated mode takes priority is displayed (arrow #24).

[0185] As indicated by arrow #23, the Partner calibrated mode can be set to on / off for each of the content viewing application 12-A and the content viewing application 12-B.

[0186] As indicated by arrow #25, the Partner Offset setting using the Offset menu 302 can be held for each of the content viewing application 12-A and the content viewing application 12-B. The Partner Offset value set when Partner calibrated mode for Service A is on is used for adjusting the image quality of Partner calibrated mode for Service A. Furthermore, the Partner Offset value set when Partner calibrated mode for Service B is on is used for adjusting the image quality of Partner calibrated mode for Service B.

[0187] As described above, when the content viewing application 12-A is running and when the content viewing application 12-B is running, settings for adjusting image quality are made using the same user interface.

[0188] Managing image quality adjustment parameters FIG. 22 is a diagram showing an example of management of image quality adjustment parameters.

[0189] As shown in FIG. 22, the picture quality adjustment parameters for Partner calibrated mode are stored and managed as table information in parameter storage area M1 together with picture quality adjustment parameters for other input types such as TV and HDMI (registered trademark).

[0190] On the other hand, the offset value of the Partner Offset is stored and managed for each application in an offset storage area M2, which is a storage area different from the parameter storage area M1.

[0191] For example, the parameter storage area M1 is formed in the RAM 109 (FIG. 10), which is a volatile storage area. The offset storage area M2 is formed in the recording unit 110, which is a nonvolatile storage area. The parameter storage area M1 and the offset storage area M2 may be formed in the same nonvolatile storage unit (medium), for example.

[0192] The table information stored in the parameter storage area M1 is configured by associating multiple types of image quality adjustment parameters with each input type. Some image quality adjustment parameters have the same value used in common by multiple input types. Image quality adjustment parameters used in common by multiple input types cannot be rewritten by content viewing applications such as content viewing application 12-A and content viewing application 12-B.

[0193] The Calibrated mode area, which is a storage area allocated to the Partner calibrated mode in the parameter storage area M1, is shared and used by, for example, a plurality of content viewing applications.

[0194] For example, when the content viewing application 12-A is started, default image quality adjustment parameters are written once in the Calibrated mode area. A set of image quality adjustment parameters for Partner calibrated mode for Service A acquired from the distribution server 2-1 is written in the Calibrated mode area by overwriting the previously stored default image quality adjustment parameters.

[0195] When Partner calibrated mode for Service A is set to ON, image quality adjustment is performed based on the image quality adjustment parameters for Partner calibrated mode for Service A written at startup and the Offset value for Partner calibrated mode for Service A stored in Offset memory area M2.

[0196] Similarly, when the content viewing application 12-B is started, the default image quality adjustment parameters are written once to the Calibrated mode area. The set of image quality adjustment parameters for Partner calibrated mode for Service B acquired from the distribution server 2-2 is written to the Calibrated mode area by overwriting the previously stored default image quality adjustment parameters.

[0197] When Partner calibrated mode for Service B is set to ON, image quality adjustment is performed based on the image quality adjustment parameters for Partner calibrated mode for Service B written at startup and the Offset value for Partner calibrated mode for Service B stored in Offset memory area M2.

[0198] Each distribution service provider can set any type of image quality adjustment parameter as the image quality adjustment parameter for Partner calibrated mode. In other words, the types of image quality adjustment parameters included in the set of image quality adjustment parameters for Partner calibrated mode may differ for each distribution service.

[0199] By writing image quality adjustment parameters in a manner that overwrites default image quality adjustment parameters that have been written once, it becomes possible to use the default image quality adjustment parameters for image quality adjustment for image quality adjustment for image quality adjustment parameters that are not included in the set.

[0200] Consider a case where a user can adjust the image quality adjustment parameters of Partner calibrated mode, such as Brightness and Color, to their liking, and the adjusted image quality adjustment parameters are written to the Calibrated mode area by a content viewing application. In this case, once the information in the Calibrated mode area is reset, the user's settings are also reset.

[0201] By storing the offset value for each distribution service in the offset storage area M2, which is a non-volatile storage area, and performing image quality adjustment using the image quality adjustment parameters written at startup and the offset value, it is possible to perform image quality adjustment that reflects the user's settings.

[0202] Among the picture quality adjustment parameters for Partner calibrated mode, there are parameters that include multiple subparameters, such as for SDR (Standard Dynamic Range), HDR (High Dynamic Range), DolbyVision HDR, etc. For example, if the content to be played is SDR content, the subparameters for SDR are used, and if it is HDR content, the subparameters for HDR are used.

[0203] When writing picture quality adjustment parameters to parameter storage area M1, regardless of the type of content to be played back (SDR / HDR, etc.), multiple sub-parameters are acquired collectively from distribution server 2 and written to parameter storage area M1. If the content to be played back is SDR content, the sub-parameters for HDR are parameters that are prepared in advance for when the content type is switched.

[0204] ·others When the user sets the Partner Offset, a log indicating the setting content may be sent to the distribution server 2.

[0205] In this case, the Offset value of Partner Offset set when Partner calibrated mode for Service A is on is transmitted to the distribution server 2-1 by the content viewing application 12-A. Also, the Offset value of Partner Offset set when Partner calibrated mode for Service B is on is transmitted to the distribution server 2-2 by the content viewing application 12-B.
