Detailed Implementation

[0016] The following describes implementation methods for this technology. The descriptions will be given in the following order.

[0017] 1. Configuration of the content delivery system

[0018] 2. Display of the Image Quality Adjustment Menu

[0019] 3. Television configuration and operation

[0020] 4. Modify the example

[0021] 5. Examples of scenarios with multiple specific distribution services

[0022] <Content Delivery System Configuration>

[0023] Figure 1 This is a diagram illustrating a configuration example of a content distribution system according to an embodiment of the present technology.

[0024] Figure 1 The content distribution system is configured by connecting television 1 and distribution servers 2-1 to 2-N via network 3 (e.g., the Internet). Remote control 4 is used to operate television 1. Commands corresponding to the buttons pressed by the user are sent from remote control 4 to television 1.

[0025] Communication is performed between television 1 and distribution servers 2-1 to 2-N via network 3. Network 3 can be any form of wired network, wireless network, or a combination of wired and wireless networks. In the following text, distribution servers 2-1 to 2-N are appropriately referred to as distribution server 2 unless there is a need to distinguish them from each other.

[0026] Television 1, which is an image processing device, receives television broadcasts from a broadcasting station (not shown), such as terrestrial digital broadcasting, satellite broadcasting, and cable broadcasting. It broadcasts programs from the radio station according to a predetermined schedule for each channel.

[0027] Television 1 displays video images of broadcast programs on a display device and outputs sound from speakers. For example, the display device of Television 1 is a display device with so-called 4K resolution (3840×2160) pixels and supports HDR video image display.

[0028] Furthermore, television 1 not only has the function of receiving programs provided by broadcasting, but also the function of receiving content provided via network 3. Content is provided via network 3, for example, through streaming. Content can also be provided through downloading.

[0029] When a pre-selected distribution service is selected, for example, using remote control 4, television 1 controls the main screen of the distribution service to be displayed on the display device. Television 1 can use multiple distribution services offered individually by different commercial providers.

[0030] Television 1 receives and reproduces the content sent from distribution server 2. Television 1 displays the video image obtained by reproducing the video data included in the content on a display device, and outputs the sound obtained by reproducing the audio data from the speakers.

[0031] Distribution server 2 is the server that provides distribution services. Distribution server 2-1 is the server that provides distribution service A, and distribution server 2-2 is the server that provides distribution service B. Distribution server 2-N is the server that provides distribution service N.

[0032] A distribution service can be provided by one distribution server 2, or by multiple distribution servers 2. It is also permissible for one distribution server 2 to provide multiple distribution services.

[0033] In this way, TV1 users can choose a pre-selected distribution service from multiple distribution services and watch content provided by the selected distribution service. TV1 is a device equipped with a general operating system (OS) and has applications installed for using individual distribution services.

[0034] Figure 2 This is a diagram illustrating an example of the application structure of television 1.

[0035] TV 1 is equipped with TV OS 11. Various applications running on TV OS 11 are installed on TV 1. Figure 2 Examples show TV viewing application 12-1, search application 12-2, image quality adjustment application 12-3, and content viewing applications 12-A to 12-N.

[0036] TV Viewing Application 12-1 is an application for managing the viewing of broadcast programs. When TV Viewing Application 12-1 is running, the user can use Remote Control 4 to select a pre-selected channel and watch the broadcast programs on the selected channel.

[0037] Search application 12-2 is an application that allows users to search for information on the internet by operating remote control 4 or by entering keywords via voice.

[0038] Image quality adjustment application 12-3 is an application that manages the image quality adjustment of the display device of television 1. When the user instructs to perform image quality adjustment, image quality adjustment application 12-3 controls the display of the image quality adjustment menu, which is a graphical user interface (GUI) for setting various items related to image quality.

[0039] The Image Quality Adjustment Application 12-3 allows users to set various image quality adjustment parameters, such as picture mode, brightness, and hue, based on their actions in the Image Quality Adjustment menu. It provides image quality adjustment functionality and an image quality adjustment menu display, as well as features of TV OS 11.

[0040] Content viewing application 12-A is an application used to access distribution service A provided by distribution server 2-1.

[0041] For example, when the content viewing application 12-A starts, the main screen of distribution service A is displayed on TV 1 based on information sent from distribution server 2-1. The main screen displays information about the visual content, such as titles and thumbnails, which the user can see and select the desired content. When the user selects the desired content, the content distribution begins.

[0042] Content viewing application 12-B is an application used to access distribution service B provided by distribution server 2-2.

[0043] Despite Figure 2 Not shown, but a dedicated application for using other distribution services is installed separately on TV1.

[0044] In addition, TV 1 also has applications installed, such as video applications for watching recorded programs recorded on external recording media such as hard disk drives (HDDs) and web browsers for displaying web pages.

[0045] For example, TV viewing application 12-1, search application 12-2, and image quality adjustment application 12-3 are software prepared by the manufacturer, which performs the manufacturing, sales, etc. of TV 1. Content viewing applications 12-A to 12-N are software prepared by commercial providers of corresponding distribution services.

[0046] <Display of the Image Quality Adjustment Menu>

[0047] Here, an example of how the image quality adjustment menu is displayed will be described. The image quality adjustment menu will be displayed differently depending on whether the content is being viewed on a specific distribution service or otherwise.

[0048] In the following text, it is assumed that distribution service A provided by distribution server 2-1 is a specific distribution service.

[0049] Examples during program viewing

[0050] Figure 3 This is an illustration showing an example of the image quality adjustment menu during program viewing.

[0051] Figure 3 The football broadcast program shown above is, for example, a recorded program. That is, Figure 3 The screen shown at the top is the screen when the video application used to watch recorded programs is running. The recorded program selected by the user is reproduced by the video application and the video image is displayed on the display device.

[0052] In display Figure 3 When the screen shown above simultaneously issues an instruction to adjust the image quality, an image quality adjustment menu 51 is displayed at the right edge of the screen, as indicated by the tip of the arrow. The video image of the recorded program continues to be displayed in the area of ​​the screen other than the area displaying the image quality adjustment menu 51.

[0053] Figure 4 It is shown Figure 3 The magnified view of the image quality adjustment menu 51.

[0054] like Figure 4 As shown, in the image quality adjustment menu 51, various items related to image quality adjustment are displayed side-by-side vertically. The dashed lines indicating the boundaries of the display areas for each item are not the actual lines displayed on the image quality adjustment menu 51.

[0055] In the upper area 61 of the image quality adjustment menu 51, the characters "Picture Adjustment" indicating the image quality adjustment menu are displayed, and below that, "Application (Video)" is displayed. "Application (Video)" indicates that the running application is a video application.

[0056] In this way, information indicating the running application is displayed in area 61. For example, if TV viewing application 12-1 is running and a broadcast program is being watched, the "Application (Tuner)" indicating that TV viewing application 12-1 is running is displayed.

[0057] Zones 62 to 67 are sequentially formed below zone 61. Items related to image quality adjustment are assigned to zones 62 to 67. The user can operate remote control 4 to select preset items and change the settings of the selected items.

[0058] Area 62 is used to set the picture mode. Picture mode is an overall image quality adjustment mode. Figure 4 In the example, "standard" is set.

[0059] For example, when selecting the "Image Mode" for the project, such as Figure 5 As shown, the image mode selection menu 51A is displayed, instead of the image quality adjustment menu 51. In Figure 5 In the example, "Vivid," "Standard," and "Movie" are displayed as settings for picture mode. The user operates remote control 4 and selects a preset setting from the settings displayed on selection menu 51A.

[0060] Back Figure 4 The description states that area 63 is used to set the automatic picture mode. Automatic picture mode is a function that automatically switches the image quality based on the content being viewed. In area 63, a switch 63A indicating whether automatic picture mode is on or off is displayed. The user can select the "Automatic Picture Mode" item to change the on / off setting of automatic picture mode. Here, the on / off setting of automatic picture mode is displayed in area 63, but "Automatic Picture Mode" can also be displayed and selected along with "Vivid," "Standard," and "Cinematic" as picture mode setting values.

[0061] Zone 64 is the area used to set brightness. Brightness refers to luminance (luminance). Figure 4 In the example, the setting value is set to "Maximum". Users can select the "Brightness" item to change the brightness setting.

[0062] Zone 65 is used to set the color. The color represents the hue. Figure 4 In the example, the value is set to "60". Users can select the "Color" item to change the hue setting.

[0063] Area 66 is used to set the light sensor. The light sensor has the function of automatically adjusting the screen brightness according to the ambient light. In area 66, a switch 66A indicating the on / off state of the light sensor is displayed.

[0064] Users can select the "Light Sensor" item to change the on / off setting of the light sensor function. Figure 4 In the example shown, the light sensor function is enabled, and switch 66A is displayed in a bright color. A shading indicator also shows switch 66A in a bright color.

[0065] Area 67 is for detailed settings. Users can select detailed settings to change several settings related to image quality.

[0066] When watching recorded or broadcast programs, use the image quality adjustment menu 51 as described above to adjust the image quality.

[0067] When viewing content provided by a distribution service other than distribution service A (which is a specific distribution service), the image quality is also adjusted using a similar image quality adjustment menu 51.

[0068] For example, when an instruction to adjust the image quality is given while viewing content provided by distribution service B, the application indicated to be run is displayed in area 61 as "Service B Application," which is the content viewing application 12-B. Similarly, when an instruction to adjust the image quality is given while viewing content provided by distribution service N, the application indicated to be run is displayed in area 61 as "Service N Application," which is the content viewing application 12-N.

[0069] Examples of content viewing during a specific distribution service

[0070] Figure 6 This is an illustration showing an example of the image quality adjustment menu during content viewing on distribution service A.

[0071] Figure 6 The content shown at the top is, for example, a movie provided by distribution service A. The content selected by the user is reproduced by the content viewing application 12-A, and the video image of the content is displayed on the display device.

[0072] In display Figure 6 When the screen shown above simultaneously issues an instruction to adjust the image quality, an image quality adjustment menu 51 is displayed at the right edge of the screen, as indicated by the tip of the arrow. The video image of the content continues to be displayed in the area of ​​the screen excluding the display area of ​​the image quality adjustment menu 51.

[0073] Figure 7 It is shown Figure 6 The enlarged view of the image quality adjustment menu 51.

[0074] exist Figure 7 The image quality adjustment menu 51 shown is displayed in the reference image quality adjustment menu. Figure 4 The same descriptions are indicated by the same reference numerals. Redundant descriptions will be omitted as appropriate.

[0075] like Figure 7 As shown, the application displayed in area 61 is the "Service A Application" of the content viewing application 12-A.

[0076] exist Figure 7 In the image quality adjustment menu 51, area 63 is used to set the Service A calibration mode. That is, area 63 becomes the area for Service A calibration mode, instead of the automatic picture mode. In area 63, a switch 63B indicating whether Service A calibration mode is on or off is displayed.

[0077] Service A calibration mode is the image quality adjustment mode for distributing Service A.

[0078] When Service A calibration mode is enabled, image quality adjustments are performed on the content of distribution service A based on the image quality adjustment parameters set for distribution service A. For example, image quality adjustments in service A calibration mode are performed using image quality adjustment parameters common to all content distributed by distribution service A.

[0079] The image quality adjustment parameters for distribution service A are preset and managed by the content viewing application 12-A. These parameters can be obtained from distribution server 2-1 when service A's calibration mode is set to on.

[0080] However, with Service A calibration mode off, image quality adjustments are performed on the content distributed via Service A based on the image quality adjustment parameters used by the user for display settings in other areas, including Picture Mode. In addition to image quality adjustments for programs and content distributed via Service A, Picture Mode can also be used for image quality adjustments of content distributed via Service A when Service A calibration mode is off.

[0081] exist Figure 7 In the example shown, Service A calibration mode is set to off. For example, the default setting for Service A calibration mode is off.

[0082] Projects and references in other areas Figure 4 The projects described are the same.

[0083] exist Figure 7 In the example, the brightness of region 64 is set to "35", and the color of region 65 is set to "50". Furthermore, the light sensor in region 66 is disabled.

[0084] Figure 8 This is a diagram showing an example of the display of the image quality adjustment menu 51.

[0085] With Service A Calibration Mode enabled, area 62 is grayed out to indicate that it is inoperable. That is, changing the image mode settings is prohibited. As an image quality adjustment mode, Service A Calibration Mode settings take precedence over image mode settings.

[0086] exist Figure 8 In the example, switch 63B in area 63 is turned on, and switch 63B is highlighted in a prominent color.

[0087] Figure 9 This is a diagram showing an example of the image quality adjustment menu 51 when Service A calibration mode has been set to enabled.

[0088] If Service A calibration mode is already enabled, such as Figure 9 As shown at the top, the picture mode is displayed in gray. In this state, if the user operates the remote control 4 to select the picture mode area 62, message 91 is displayed, indicating that changing the picture mode is prohibited, as indicated by the arrow tip.

[0089] In the case of changing the image mode, the user switches the setting of Service A calibration mode to off, and then changes the image mode.

[0090] Back Figure 8 The description states that the brightness of region 64 is set to "40" and the color of region 65 is set to "70". These brightness and color settings are based on the image quality adjustment parameters of distribution service A. Other items included in the detailed settings are also appropriately set based on the image quality adjustment parameters of distribution service A.

[0091] Even when Service A calibration mode is enabled, items other than those in image mode are displayed in an operable state. Users can change the settings for items other than those in image mode.

[0092] In this way, TV 1 is provided with Service A calibration mode, which is the image quality adjustment mode used to distribute Service A.

[0093] The image quality adjustment parameters for Service A calibration mode are, for example, parameters prepared by the commercial provider distributing Service A. For the content distributed via Service A, the commercial provider of Service A applies the desired image quality adjustments.

[0094] The commercial provider of distribution service A can allow users to view video images with the image quality expected by the commercial provider.

[0095] Furthermore, as a user, you can view the video images of the content in the image quality expected by the commercial provider.

[0096] The process of performing image quality adjustment on TV 1 as described above will be described later with reference to the flowchart.

[0097] <TV Configuration and Operation>

[0098] TV configuration

[0099] Figure 10 This is a block diagram illustrating an example of the hardware configuration of TV 1.

[0100] Tuner 101 receives broadcast signal from an antenna (not shown) or from satellite broadcasting or a cable TV set-top box, and extracts the signal of a user-selected channel. Tuner 101 performs various processes on the extracted signal, such as A / D conversion and demodulation, and outputs the program data obtained by performing these processes to decoder 102.

[0101] Decoder 102 decodes the video stream included in the program data and outputs the data of each frame obtained through decoding to signal processing unit 103. Additionally, decoder 102 decodes the audio stream included in the program data and outputs the program's audio data to signal processing unit 103.

[0102] In reproducing the content of the predetermined distribution service, decoder 102 decodes the video and audio streams of the content received by communication unit 111 and provided via bus 106. Decoder 102 outputs data of each image obtained by decoding the video stream of the content and sound data obtained by decoding the audio stream to signal processing unit 103.

[0103] Under the control of the CPU 107, the signal processing unit 103 performs image quality adjustment on each image provided by the decoder 102. The signal processing unit 103 outputs the image quality adjusted image to the display device 104 and controls it to display the video image of the program or content.

[0104] In addition, the signal processing unit 103 performs D / A conversion and other operations on the audio data provided from the decoder 102, synchronizes with the video image, and outputs the audio of the program or content from the speaker 105.

[0105] Display device 104 is a display with 4K resolution pixels and supports HDR video image display. Display device 104 includes liquid crystal display (LCD), organic EL display, etc.

[0106] The central processing unit (CPU) 107, read-only memory (ROM) 108, and random access memory (RAM) 109 are interconnected via bus 106. The CPU 107 executes programs recorded in ROM 108 or recording unit 110 using RAM 109 and controls the entire television 1.

[0107] Recording unit 110 includes recording media such as hard disk drives (HDDs) or solid-state drives (SSDs). Recording unit 110 records various types of data, such as program data, content, EPG data, and programs.

[0108] Communication unit 111 is the interface of network 3. Communication unit 111 communicates with distribution server 2.

[0109] 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.

[0110] Figure 11 This is a block diagram illustrating an example of the functional configuration of TV 1.

[0111] like Figure 11 As shown, in television 1, a content reproduction control unit 121, an image quality adjustment control unit 122, and a menu display control unit 123 are implemented.

[0112] By Figure 10 The CPU 107 executes a predefined program to achieve this. Figure 11 At least a portion of the functional units shown. For example, the content playback control unit 121 is implemented by executing the content viewing application 12-A. The image quality adjustment control unit 122 and the menu display control unit 123 are implemented by executing the image quality adjustment application 12-3.

[0113] The content playback control unit 121 communicates with the distribution server 2-1 via the control communication unit 111 and requests the distribution server 2-1 to send the content selected by the user. The content playback control unit 121 controls the decoder 102 to reproduce the content sent from the distribution server 2-1.

[0114] The image quality adjustment control unit 122 controls the image quality adjustment of the program or content performed by the signal processing unit 103.

[0115] For example, when reproducing content from distribution service A, which is a specific distribution service, and with service A's calibration mode already enabled, the image quality adjustment control unit 122 performs control to perform image quality adjustment according to the image quality adjustment parameters of distribution service A. The image quality adjustment parameters of distribution service A include, for example, a set of parameters representing setting values ​​for multiple items.

[0116] Furthermore, when reproducing a program, or when reproducing content from a distribution service other than distribution service A, the image quality adjustment control unit 122 performs image quality adjustment according to the image quality adjustment parameters set by the user.

[0117] When an instruction to adjust the image quality is given, the menu display control unit 123 causes the display device 104 to display the image quality adjustment menu. Furthermore, as described above, the menu display control unit 123 switches the display of the image quality adjustment menu according to the user's operation.

[0118] TV operation

[0119] See here for reference. Figure 12 The flowchart in the document will describe the image quality adjustment process for television 1.

[0120] For example, when the user instructs to perform image quality adjustments, start Figure 12 The processing.

[0121] In step S1, the menu display control unit 123 determines whether it is viewing the content of distribution service A as a specific distribution service.

[0122] If, in step S1, it is determined that content from distribution service A is being viewed, in step S2, the menu display control unit 123 controls the display of an image quality adjustment menu, including the service A calibration mode. Figure 7 This calibration mode is the image quality adjustment mode for distribution service A.

[0123] In step S3, the menu display control unit 123 switches the display of the image quality adjustment menu as described above according to the user's operation.

[0124] In step S4, the menu display control unit 123 determines whether to close the image quality adjustment menu. When it is desired to close the image quality adjustment menu, the process returns to step S3, and the display of the image quality adjustment menu continues until a determination is made in step S4.

[0125] If it is determined in step S4 that the image quality adjustment menu will be turned off, in step S5, the image quality adjustment control unit 122 controls the image quality adjustment of the content of distribution service A, and controls the display of the video image after the image quality adjustment. For example, if the calibration mode of service A is set to on using the image quality adjustment menu, the image quality adjustment control unit 122 controls the image quality adjustment to be performed according to the image quality adjustment parameters of distribution service A.

[0126] However, if it is determined in step S1 that no content from distribution service A has been viewed, in step S6, the menu display control unit 123 controls the display of the normal image quality adjustment menu. Figure 4 The image quality adjustment menu shown here does not include items for Service A calibration mode.

[0127] In step S7, the menu display control unit 123 switches the display of the normal image quality adjustment menu according to the user's operation.

[0128] In step S8, the menu display control unit 123 determines whether to close the normal image quality adjustment menu. When it is desired to close the normal image quality adjustment menu, the process returns to step S7, and the display of the normal image quality adjustment menu continues until a determination is made in step S8.

[0129] If it is determined in step S8 that the normal image quality adjustment menu should be turned off, 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 controls the display of the video image after image quality adjustment.

[0130] After image quality adjustment is performed in step S5 or step S9, the process ends.

[0131] Through the above processing, the commercial provider of distribution service A can allow users to view video images with the image quality expected by the commercial provider. Furthermore, users can view the video images of the content with the image quality expected by the commercial provider.

[0132] Note that the content distributed by distribution service A can be either content recording SDR video images or content recording HDR video images. The maximum brightness of the SDR video image is 100 nits (100 cd / m²). 2 ), while the maximum brightness of HDR video images exceeds 10,000 nits.

[0133] In the case that the display device 104 of the television 1 is a display that supports HDR video image display as described above, the adjustment range is wide. Therefore, there is a possibility that the user performs image quality adjustments that differ from those expected by the commercial provider. It is believed that the Service A calibration mode (which is the image quality adjustment mode used to distribute Service A) is particularly effective when displaying content containing HDR video images.

[0134] <Modification Example>

[0135] Example of setting image quality adjustment parameters

[0136] It has been assumed that the image quality adjustment parameters used when service A's calibration mode is enabled are image quality adjustment parameters shared by all content distributed by distribution service A. However, image quality adjustment parameters can be prepared for each piece of content. In this case, the image quality adjustment parameters are prepared, for example, by the content creator and managed by distribution server 2-1.

[0137] Reference Figure 13 The flowchart describes the image quality adjustment process for each content in the case of preparing image quality adjustment parameters.

[0138] For example, when Service A's calibration mode is set to enabled, Figure 13 The processing begins.

[0139] In step S21, the image quality adjustment control unit 122 communicates with the distribution server 2-1, which is a server for a specific distribution service, and obtains the image quality adjustment parameters of the content to be reproduced.

[0140] In step S22, the image quality adjustment control unit 122 causes the signal processing unit 103 to perform image quality adjustment of the content according to the image quality adjustment parameters obtained from the distribution server 2-1.

[0141] Therefore, creators of content distributed by distribution service A can allow users to view video images with the image quality desired by the creator.

[0142] Image quality adjustment parameters can be prepared for each type of content distributed by distribution service A, or for each model of television 1. Furthermore, image quality adjustment parameters can be prepared for each display function of the display device 104 included in television 1.

[0144] It is possible Figure 14 The reproduction device 201 shown in A or Figure 14The image quality adjustment of the television 1 as described above is performed on the mobile terminal 202 shown in B. The playback device 201 is an apparatus such as a set-top box or a device that supports playback of a predetermined packaged medium.

[0145] For example, when Service A calibration mode has been set to enabled, the playback device 201 performs image quality adjustment of the content based on the image quality adjustment parameters of the distribution service A, and outputs the video image after image quality adjustment to the television 1 for display.

[0146] Other examples

[0147] As parameters for a specific distribution service, parameters can be prepared for image quality adjustment, but parameters can also be prepared for audio quality adjustment of the content.

[0148] With Service A calibration mode already enabled, TV 1 will adjust the audio of the content based on the parameters of Service A and output the audio after the audio quality is adjusted.

[0149] <Example of a scenario with multiple specific distribution services>

[0150] The case where a specific distribution service is distribution service A has been described, but multiple distribution services can be prepared as a specific distribution service.

[0151] In this scenario, users can utilize image quality adjustment features similar to the calibration mode described above for Service A, not only for viewing Distribution Service A, but also for viewing content from other Distribution Services such as Distribution Service B and Distribution Service C.

[0152] Figure 15 This is a diagram showing an example of providing image quality adjustment parameters.

[0153] When the content viewing application 12-A is running on the TV 1, communication is performed between the content viewing application 12-A and the distribution server 2-1, and the distribution server 2-1 provides the content viewing application 12-A with the image quality adjustment parameters of the distribution service A, as shown by arrow #1.

[0154] Image quality adjustment parameters can be provided when Service A calibration mode is set to on, as described above, or they can be provided at any time, such as when content distribution begins.

[0155] With Service A calibration mode already enabled, image quality adjustment of the content distributed via Service A is performed based on image quality adjustment parameters provided by distribution server 2-1. For example, image quality adjustment control unit 122 performs the acquisition of image quality adjustment parameters and the image quality adjustment based on those parameters.

[0156] The provision of these image quality adjustment parameters is also performed by the distribution server that manages other distribution services.

[0157] Figure 16 This is a diagram showing another example of providing image quality adjustment parameters.

[0158] For example, if an image quality adjustment mode has already been prepared for distribution service B, the distribution server 2-2, which manages distribution service B, provides the image quality adjustment parameters to be used in the image quality adjustment mode of distribution service B.

[0159] That is, the content viewing application 12-B running on TV 1 ( Figure 2 Communication is performed between the content viewing application 12-B and the distribution server 2-2, and the distribution server 2-2 provides the content viewing application 12-B with the image quality adjustment parameters of the distribution service B, as shown by arrow #2.

[0160] Image quality adjustment parameters for distribution service B are also available at any time, such as when the image quality adjustment mode of distribution service B is set to on, or when content distribution begins.

[0161] If the image quality adjustment mode of distribution service B has been set to enabled, the image quality adjustment of the content of distribution service B is performed based on the image quality adjustment parameters provided by distribution server 2-2.

[0162] When preparing image quality adjustment modes for multiple distribution services in this manner, the display of the image quality adjustment menu differs from the reference. Figure 8 The image quality adjustment menu 51, as described above, is displayed.

[0163] About screen display

[0164] Figure 17 This is a diagram showing an example of the image quality adjustment menu.

[0165] When an instruction to adjust the image quality is given while viewing the content of distribution service A, an image quality adjustment menu 301 is displayed on the right edge of the screen, such as... Figure 17 As shown at the top. The video image of the content from distribution service A continues to be displayed in the area of ​​the entire screen excluding the display area of ​​the image quality adjustment menu 301.

[0166] In the image quality adjustment menu 301, items similar to those in the image quality adjustment menu 51 described above are displayed side-by-side vertically. Further descriptions will be omitted as appropriate.

[0167] Figure 18 It is shown Figure 17 The magnified view of the image quality adjustment menu 301.

[0168] The uppermost area 301A is the area that displays information indicating the input type (input type) of the display device 104. Figure 18 In the example, the input type is "partner application".

[0169] The “Partner Application” indicates that an application for using the allocation service is being executed, a dedicated image quality adjustment mode is prepared for the allocation service, and the video image acquired by the application is displayed on the display device 104.

[0170] "Partners" refers to commercial providers of distribution services A, B, etc., who have prepared dedicated image quality adjustment modes for them. In the following text, the image quality adjustment modes dedicated to "partners" are appropriately referred to as "partner calibration modes".

[0171] Areas 311 to 316, located below area 301A, are areas for user operation. Items related to image quality adjustment are assigned to areas 311 to 316. The user can operate remote control 4 to select preset items and change the settings of the selected items.

[0172] Area 311 is used to set the image mode. Figure 18 In the example, "Standard" is set to picture mode.

[0173] Zone 312 is the zone used to set the automatic picture mode.

[0174] The displays of regions 311 and 312 are respectively compared with the reference, for example. Figure 4 The descriptions for areas 62 and 63 are identical.

[0175] Zone 313 is used to set the Partner Calibration Mode, a dedicated image quality adjustment mode for "Partners". (This is because I am currently watching content from Distribution Service A.) Figure 18 The text "Partner Calibration Mode for Service A" is displayed in area 313. "Partner Calibration Mode for Service A" is the same as the partner calibration mode for distributing Service A, i.e., the calibration mode for Service A mentioned above.

[0176] Note that in Figure 18 In the example, the partner calibration mode setting is turned off. For instance, the default setting for partner calibration mode is off.

[0177] When the user selects zone 313 by operating remote control 4, the partner calibration mode can be turned on / off.

[0178] Region 314 is the area used to set brightness as an image quality adjustment parameter. Figure 18 In the example, the setting value is "35".

[0179] Region 315 is used to set color as an image quality adjustment parameter. Figure 18 In the example, the setting value is "60".

[0180] The displays of regions 314 and 315 are respectively compared with the reference, for example. Figure 8 The display in areas 64 and 65 is identical. With partner calibration mode off, users can freely adjust image quality parameters for brightness and color.

[0181] Region 316 is used to set the partner offset. The partner offset is used for image quality adjustment when partner calibration mode is already set to on. Setting the offset value to the partner offset allows for further adjustment of image quality, with the image quality adjustment parameters set according to partner calibration mode.

[0182] That is, by setting the partner offset, users can also watch video images with finely adjusted image quality according to user preferences, instead of the original video images in partner calibration mode (video images with image quality adjusted using image quality adjustment parameters provided by the distribution service).

[0183] like Figure 18 As shown, region 316 is displayed in gray when partner calibration mode is set to off. In this case, the partner offset setting is disabled.

[0184] exist Figure 18 In the diagram, the fact that region 316 is colored indicates that region 316 is displayed as gray. Regions 311 to 315 that are not grayed out are regions that can be manipulated by the user.

[0185] Using this display of the image quality adjustment menu 301, users can adjust the image quality of the content in distribution service A.

[0186] Back Figure 17 As described, when Partner Calibration Mode (Partner Calibration Mode of Service A) is enabled, as indicated by the tip of arrow #11, the content's video image is switched to a video image after image quality adjustment using Partner Calibration 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. Figure 17In the example, the setting value "60" for brightness and the setting value "50" for color are used as image quality adjustment parameters in the partner calibration mode.

[0187] In the image quality adjustment menu 301, among areas 311 to 316, only area 313 of the partner calibration mode and area 316 of the partner offset mode are operable, and the other areas are displayed in gray.

[0188] exist Figure 17 In the lower image quality adjustment menu 301, the collaborator calibration mode setting for area 313 is enabled. Furthermore, the image mode setting for area 311 is "partner calibrated," indicating that the partner calibration mode has priority.

[0189] In this state, with Partner Calibration Mode set to Off, as indicated by the tip of arrow #12, the video image of the content is switched to a video image without image quality adjustment performed under Partner Calibration Mode. The display of Image Quality Adjustment Menu 301 will also return to its Off state before Partner Calibration Mode is set to On.

[0190] Figure 19 This is a diagram showing an example of the display when the partner offset is set.

[0191] like Figure 19 As shown at the top, with Partner Calibration Mode enabled, when setting Partner Offset in the bottom column of Image Quality Adjustment Menu 301, Offset Menu 302 is displayed instead of Image Quality Adjustment Menu 301, as indicated by the tip of arrow #13. Offset Menu 302 is displayed to set the Partner Offset.

[0192] Figure 20 This is a magnified view showing the offset menu 302.

[0193] In the topmost area 302A, the words “Partner Offset (Service A)” are displayed, indicating that the offset menu 302 is a menu for setting partner offsets.

[0194] Areas 331 and 332 below area 302A are areas used for user operations.

[0195] exist Figure 20 In the example, region 331 is the region used to set the brightness offset value. Additionally, region 332 is the region used to set the color offset value.

[0196] Users can set the brightness offset value by selecting area 331. Additionally, users can set the color offset value by selecting area 332.

[0197] Offset values ​​can be set using the option to use a relative expression relative to a standard, such as selecting one of five levels, or choosing any level from +5 / +3 / -3 / -5.

[0198] That is, the unit of the offset value is different from the unit of adjustment parameters such as brightness and color. The offset value is not an absolute number; for example, the value used to indicate brightness and color (…). Figure 18 (referring to "35" and "60" in the text).

[0199] For example, if "+5" is selected as the brightness offset value, the predetermined value corresponding to "+5" is added to "60", which is the brightness specified by the partner calibration mode, and the added value is used to adjust the brightness.

[0200] After setting the offset value, the display returns to... Figure 19 The upper part of the status displays the image quality adjustment menu 301.

[0201] Note that in Figure 19 In the example, assume 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 will be different for each partner calibration mode. For example, in the partner calibration mode for distribution service B (Partner Calibration Mode for Service B), offset values ​​for more types of image quality adjustment parameters can also be set.

[0202] Even when watching content from distribution service B, use a display similar to the one shown above to make various settings related to image quality adjustment, including the partner calibration mode settings.

[0203] Figure 21 This is a diagram showing an example of a screen display for each distribution service.

[0204] Figure 21 The display shown on the left illustrates the screen display as described above when the content viewing application 12-A is running and content from distribution service A is being viewed. The upper display shows the display with service A's partner calibration mode off, the middle display shows the display with service A's partner calibration mode on, and the lower display shows the offset menu 302.

[0205] However, Figure 21The display shown on the right illustrates the screen display when the content viewing application 12-B is running and content from distribution service B is being viewed. The upper part shows the display with service B's partner calibration mode off, the middle part shows the display with service B's partner calibration mode on, and the lower part shows the offset menu 302.

[0206] As shown by arrow #21, the input type display of the image quality adjustment menu 301 is "Partner Application" for both the content viewing application 12-A and the content viewing application 12-B that are running.

[0207] As indicated by arrows #22 and #24, the display of the picture mode in the image quality adjustment menu 301 is consistent when both content viewing application 12-A and content viewing application 12-B are running. With partner calibration mode off, a setting value, such as "Standard," is displayed to indicate the user's selection (arrow #22). With partner calibration mode on, "Partner Calibration" is displayed to indicate that partner calibration mode has priority (arrow #24).

[0208] As shown by arrow #23, the Partner Calibration Mode can be individually set to on / off for each of the Content Viewing Apps 12-A and 12-B.

[0209] As indicated by arrow #25, for each of the content viewing applications 12-A and 12-B, the partner offset setting using the offset menu 302 can be maintained individually. The partner offset value set when partner calibration mode is enabled in service A is used for image quality adjustment in service A's partner calibration mode. Furthermore, the partner offset value set when partner calibration mode is enabled in service B is used for image quality adjustment in service B's partner calibration mode.

[0210] As described above, image quality adjustment settings are made using a similar user interface when content viewing application 12-A and content viewing application 12-B are running.

[0211] Management of image quality adjustment parameters

[0212] Figure 22 This is a diagram illustrating an example of managing image quality adjustment parameters.

[0213] like Figure 22As shown, the image quality adjustment parameters in the partner calibration mode are stored and managed in the parameter storage area M1, along with image quality adjustment parameters for other input types such as TV and HDMI (registered trademark), as tabular information.

[0214] However, the offset values ​​of the partners are stored and managed in the offset storage area M2, which is different from the parameter storage area M1 for each application.

[0215] For example, parameter storage area M1 is formed in RAM 109 ( Figure 10 In this configuration, RAM 109 is a volatile storage area. Offset storage area M2 is formed in recording cell 110, which is a non-volatile storage area. Parameter storage area M1 and offset storage area M2 may, for example, be formed in the same non-volatile storage cell (medium).

[0216] By associating multiple types of image quality adjustment parameters for each input type, tabular information is formed and stored in the parameter storage area M1. In some image quality adjustment parameters, the same value is often used for multiple input types. Image quality adjustment parameters commonly used for multiple input types cannot be rewritten from content viewing applications such as Content Viewing Application 12-A and Content Viewing Application 12-B.

[0217] For example, the calibration mode area is a storage area in parameter storage area M1 allocated to partner calibration modes, which is shared and used by multiple content viewing applications.

[0218] For example, when the content viewing application 12-A starts, the default image quality adjustment parameters are written once in the calibration mode area. A set of image quality adjustment parameters for the partner calibration mode of service A, obtained from the distribution server 2-1, is written to the calibration mode area in a manner that overwrites the previously stored default image quality adjustment parameters.

[0219] When the partner calibration mode of service A is enabled, image quality adjustment is performed based on the image quality adjustment parameters of the partner calibration mode of service A written at startup, and based on the offset value of the partner calibration mode of service A stored in the offset storage area M2.

[0220] Similarly, when the content viewing application 12-B starts, the default image quality adjustment parameters are written once in the calibration mode area. A set of image quality adjustment parameters for the partner calibration mode of Service B, obtained from distribution server 2-2, is written to the calibration mode area in a manner that overwrites the previously stored default image quality adjustment parameters.

[0221] When the partner calibration mode of service B is enabled, image quality adjustment is performed based on the image quality adjustment parameters of the partner calibration mode of service B written at startup, and based on the offset value of the partner calibration mode of service B stored in the offset storage area M2.

[0222] Each distribution service provider can set any type of image quality adjustment parameter as the image quality adjustment parameter in the partner calibration mode. That is, the types of image quality adjustment parameters included in the image quality adjustment parameter set of the partner calibration mode may vary from one distribution service to another.

[0223] By allowing image quality adjustment parameters to be written in an overwrite manner after the default image quality adjustment parameters have been written once, the default image quality adjustment parameters can be used for image quality adjustment for image quality adjustment parameters not included in the set.

[0224] Consider a scenario where a user can adjust image quality adjustment parameters, such as brightness and color, in a partner calibration mode according to their preferences, and these adjusted parameters are written to the calibration mode area by the content viewing application. In this case, the user's settings are reset once the information in the calibration mode area is reset.

[0225] Image quality adjustments can be performed to reflect the user's settings by storing the offset value of each distribution service in the offset storage area M2, which is a non-volatile storage area, and by using the image quality adjustment parameters and offset values ​​written at startup.

[0226] The image quality adjustment parameters in Partner Calibration Mode include parameters with multiple sub-parameters, such as Standard Dynamic Range (SDR) / High Dynamic Range (HDR) / Dolby Vision HDR / ... For example, if the content to be reproduced is SDR, the SDR sub-parameter is used, and if the content is HDR, the HDR sub-parameter is used.

[0227] When writing image quality adjustment parameters to parameter storage area M1, regardless of the type of content to be reproduced, multiple sub-parameters, such as SDR / HDR, are jointly obtained from distribution server 2 and written to parameter storage area M1. If the content to be reproduced is SDR content, the HDR sub-parameter is a parameter prepared in advance for switching types.

[0228] other

[0229] When the partner offset is set by the user, a log showing the settings can be sent to distribution server 2.

[0230] In this scenario, the partner offset value set when partner calibration mode is enabled for service A is sent by content viewing application 12-A to distribution server 2-1. Furthermore, the partner offset value set when partner calibration mode is enabled for service B is sent by content viewing application 12-B to distribution server 2-2.

[0231] Computer configuration examples

[0232] The above series of processes can be executed by hardware or software. In the case of software execution, the program forming the software is installed from a program recording medium onto a computer, general-purpose personal computer, or similar hardware contained within it.

[0233] Figure 23 This is a block diagram illustrating an example of the hardware configuration of a computer performing the above series of processes according to a program.

[0234] The central processing unit (CPU) 1001, read-only memory (ROM) 1002 and random access memory (RAM) 1003 are interconnected via bus 1004.

[0235] The bus 1004 is also connected to the input / output interface 1005. The input / output interface 1005 is connected to the input unit 1006, which includes a keyboard, mouse, etc., and the output unit 1007, which includes a display device, speaker, etc. In addition, the input / output interface 1005 is connected to the storage unit 1008, which includes a hard disk, non-volatile memory, etc., the communication unit 1009, which includes a network interface, etc., and the driver 1010 that drives the removable medium 1011.

[0236] In a computer configured as described above, for example, the above series of processes are performed by loading the program recorded in the storage unit 1008 into the RAM 1003 and executing it via the input / output interface 1005 and the bus 1004 through the CPU 1001.

[0237] For example, a program executed by the CPU 1001 may be provided for installation in the storage unit 1008 by recording on the removable medium 1011 or via a wired or wireless transmission medium (e.g., a local area network, the Internet, and digital broadcasting).

[0238] Note that a program executed by a computer may be a program that performs processing sequentially in the order described in this specification, or it may be a program that performs processing in parallel or at necessary times (e.g., when a call is made).

[0239] In this specification, a system refers to a group of multiple components (devices, modules (parts), etc.), and it is not important whether all components are housed in the same enclosure. Therefore, multiple devices housed in separate enclosures and connected via a network, and a single device having multiple modules housed in one enclosure are both systems.

[0240] The effects described in this manual are merely examples and are not limited to these; other effects may also exist.

[0241] The implementation of this technology is not limited to the above-described implementation, and various modifications can be made without departing from the scope of this technology.

[0242] For example, this technology can have a cloud computing configuration, in which a function is shared and collaboratively processed by multiple devices via a network.

[0243] Furthermore, each step described in the flowchart above can be performed by one device, or it can be shared and performed by multiple devices.

[0244] Furthermore, in cases where a step includes multiple processes, the multiple processes included in a step can be executed by one device, or they can be shared and executed by multiple devices.
