Next, the functions of the respective devices of the image quality adjustment system 1 according to the first embodiment will be described. Fig. 7 is a block diagram showing an example of the functional configuration of each device of the image quality adjustment system 1 according to the first embodiment.
The CPU101 of the management server 10 reads and executes a program stored in the ROM103 or the like, thereby generating each functional unit in the RAM 102. Specifically, the management server 10 includes a storage control unit 1001, an update unit 1002, and a transmission unit 1003 as functional units.
The storage control unit 1001 causes the storage unit 104 to store content property information 107 indicating the property of the image quality of the content and display setting information 109 indicating the display setting of the property of the image quality of each content. Further, the storage control unit 1001 causes the storage unit 104 to store the characteristic content information 106 indicating the characteristics of the image quality of the content.
The update unit 1002 updates the property content information 106, the content property information 107, and the display setting information 109. The update unit 1002 may update all of the property content information 106, the content property information 107, and the display setting information 109 at the same time or at different times. That is, the update unit 1002 updates at least one of the property content information 106, the content property information 107, and the display setting information 109. Here, the method of updating various information by the updating unit 1002 is not limited. For example, the updating unit 1002 may update various information based on an operation performed by the administrator of the image quality adjustment system 1, may update various information using a model after learning generated by deep learning, or may update various information based on received data.
The transmission unit 1003 transmits the characteristic content information 106, the content characteristic information 107, and the display setting information 109 to the television device 20. More specifically, when the characteristic content information 106, the content characteristic information 107, and the display setting information 109 stored in the storage unit 104 are newer than the characteristic content information 106, the content characteristic information 107, and the display setting information 109 of the television device 20 that is the request source, the transmission unit 1003 transmits the information to the television device 20. When transmitting the display setting information 109, the transmission unit 1003 transmits the display setting information 109 corresponding to the device type of the television apparatus 20 that is the request source.
Further, when the property content information 106, the content property information 107, and the display setting information 109 are not all updated by the update unit 1002, the transmission unit 1003 may not transmit the non-updated information. That is, the transmission unit 1003 transmits at least one of the property content information 106, the content property information 107, and the display setting information 109.
The CPU214 of the television apparatus 20 reads out and executes a program stored in the ROM or the like to generate each functional unit in the RAM. Specifically, the television device 20 includes a content acquisition unit 2001, a reception unit 2002, a setting change unit 2003, a characteristic determination unit 2004, and a display control unit 2005 as functional units.
The content acquisition unit 2001 receives a broadcast, thereby acquiring content including metadata, a video signal, and an audio signal.
The receiving unit 2002 receives content property information 107 for specifying a property of the image quality of the content, and display setting information 109 indicating a display setting of the content for each property. In addition, the receiving unit 2002 receives the property content information 106. The receiving unit 2002 is an example of a first receiving unit.
More specifically, the receiving unit 2002 determines whether or not the character content information 106, the content property information 107, and the display setting information 109 stored in the storage unit 104 of the management server 10 are newer than the character content information 106, the content property information 107, and the display setting information 109 that the television device 20 has, every time an arbitrary period elapses. That is, the receiving unit 2002 determines whether or not the characteristics content information 106, the content characteristics information 107, and the display setting information 109 have been updated after the characteristics content information 106, the content characteristics information 107, and the display setting information 109 have been received the previous time. Then, when the characteristic content information 106, the content characteristic information 107, and the display setting information 109 stored in the storage unit 104 of the management server 10 are newer than the characteristic content information 106, the content characteristic information 107, and the display setting information 109 of the television device 20, the receiving unit 2002 requests the management server 10 for the characteristic content information 106, the content characteristic information 107, and the display setting information 109. Thus, the receiving unit 2002 receives the property content information 106, the content property information 107, and the display setting information 109.
The setting changing unit 2003 changes the items of the display settings set for each characteristic of the image quality of the content, which are not changed in the television apparatus 20, to the settings indicated by the display setting information 109. The setting changing unit 2003 is an example of a changing unit. Here, the user changes the display setting of the television apparatus 20 based on his or her preference. When displaying content, the television device 20 preferably displays the content with display settings according to the preference of the user. Therefore, the setting changing unit 2003 changes the items of the display setting that are not changed by the user. The setting changing unit 2003 may change each item of the display setting based on the setting changed by the user. For example, when the display setting information 109 indicates that the setting of +3 is changed for a certain item, the setting changing unit 2003 may change the setting by adding 3 to the setting value set by the user.
The characteristic determination unit 2004 determines the characteristic of the image quality of the broadcast content based on the content characteristic information 107. The characteristic determination unit 2004 is an example of a first determination unit. Here, the content includes metadata indicating information of the content (contents). The metadata includes information such as a broadcasting method, SID, genre (Genre), and Code, a title of the content, and a comment describing a summary of the content. The property determination unit 2004 compares the content property information 107 with the metadata of the content to determine whether or not the content matches any line (row). Then, the characteristic specifying unit 2004 determines that the characteristic specified by the image quality characteristic code of the matching line (row) is a characteristic of the image quality of the content.
Here, when a new program or a broadcasting method is added, a new line (row) is added to the content property information 107. Therefore, the characteristic determining unit 2004 determines whether or not the line (row) coincides with it, in the order in which the line (row) is new. Thus, the characteristic determining unit 2004 can select an appropriate characteristic.
The display control unit 2005 causes the display panel 210 to display the content adjusted based on the display setting of the characteristic determined by the characteristic determining unit 2004. More specifically, the display control unit 2005 adjusts the content based on the display setting of the characteristic determined by the characteristic determination unit 2004. Then, the display control unit 2005 causes the display panel 210 to display the adjusted content. Thus, the display control unit 2005 can display the content with the display setting according to the characteristic of the image quality of the content.
Next, a process executed by each device of the image quality adjustment system 1 according to the first embodiment will be described.
Fig. 8 is a flowchart showing an example of information management processing executed by the management server 10 of the first embodiment.
The update unit 1002 determines whether or not an update request requesting update of at least one of the property content information 106, the content property information 107, and the display setting information 109 is received (step S1).
When the update request is received (step S1; yes), the update unit 1002 updates the information to be the update request (step S2).
When the update request is not received (step S1; no), the transmission unit 1003 determines whether or not a transmission request requesting transmission of at least any one of the content property information 106, the content property information 107, and the display setting information 109 is received from the television apparatus 20 (step S3). In the case where the transmission request is not received (step S3; no), the management server 10 shifts to step S1.
When receiving the transmission request (step S3; yes), the transmission unit 1003 transmits information to be subjected to the transmission request to the television device 20 (step S4).
As described above, the management server 10 executes the information management processing.
Fig. 9 is a flowchart showing an example of the adjustment process executed by the television apparatus 20 according to the first embodiment.
After the television device 20 receives the content data, the receiving unit 2002 determines whether or not the updated property content information 106, content property information 107, or display setting information 109 is stored in the management server 10 (step S11).
When the updated property content information 106, content property information 107, or display setting information 109 is already stored in the management server 10 (step S11; yes), the receiving unit 2002 receives the updated property content information 106, content property information 107, or display setting information 109 from the management server 10 (step S12).
If the updated property content information 106, content property information 107, or display setting information 109 is not stored in the management server 10 (step S11; no), the content acquisition unit 2001 determines whether or not the content is acquired (step S13). In the case where the content is not acquired (step S13; no), the television device 20 shifts to step S11.
When the content is acquired (step S13; yes), the characteristic specifying unit 2004 specifies the characteristic of the image quality of the content based on the content characteristic information 107 (step S14).
The display control unit 2005 adjusts the video signal based on the display setting of the characteristic determined by the characteristic determining unit 2004 (step S15). The display control unit 2005 causes the display panel 210 to display the adjusted video signal (step S16).
As described above, the television apparatus 20 performs the adjustment processing.
As described above, the television apparatus 20 of the first embodiment receives the content property information 107 and the display setting information 109 from the management server 10. The television device 20 changes the setting indicated by the display setting information 109 to the item whose setting has not been changed by the user in the display setting.
