Abstract

A content processing device causing a display device connected thereto to output content includes: a first acquisition unit that acquires video luminance information included in the content from service information included in the content; a second acquisition unit that acquires, from the display device, display luminance information in a case where the display device performs display; and an information processing unit that notifies a viewer, who views the content, of information based on the video luminance information and the display luminance information via the display device.

First claim

1 . A content processing device causing a display device connected thereto to output content, the content processing device comprising:
a first acquisition unit that acquires video luminance information included in the content from service information included in the content; a second acquisition unit that acquires display luminance information in a case where the display device performs display; and an information processing unit that notifies a viewer, who views the content, of information based on the video luminance information and the display luminance information via the display device.

2 . The content processing device according to claim 1 , wherein
the information processing unit combines the information based on the video luminance information and the display luminance information with video data, and causes the display device to display the resultant on a screen in which information about the content is displayed.

3 . The content processing device according to claim 1 , further comprising
a display screen generation unit that, on a basis of the video luminance information and the display luminance information, generates a luminance information display screen in which display is performed in a display form according to a magnitude relationship between luminance indicated by the video luminance information and luminance indicated by the display luminance information, wherein the information processing unit causes the display device to display the generated luminance information display screen together with the screen in which the information about the content is displayed.

4 . The content processing device according to claim 3 , wherein
the display screen generation unit generates a luminance information display screen in which display is performed in a different display form in accordance with a ratio of the luminance indicated by the display luminance information relative to the luminance indicated by the video luminance information.

5 . The content processing device according to claim 1 , wherein
the information processing unit causes the display device to display the information based on the video luminance information and the display luminance information to be associated with content information in a program table of the content.

6 . The content processing device according to claim 1 , wherein
the second acquisition unit acquires the display luminance information from the display device or a storage region in which the display luminance information is stored.

7 . The content processing device according to claim 1 , further comprising the display device.

8 . A television reception device comprising:
a reception device that receives content; a display device; and a content processing device that causes the display device to output the received content, wherein the content processing device includes a first acquisition unit that acquires video luminance information included in the content from service information included in the content, a second acquisition unit that acquires display luminance information in a case where the display device performs display, and an information processing unit that notifies a viewer, who views the content, of information based on the video luminance information and the display luminance information via the display device.

9 . A method of processing information in a content processing deice causing a display device connected thereto to output content, the method comprising the steps of:
acquiring, by a first acquisition unit, video luminance information included in the content from service information included in the content; acquiring, by a second acquisition unit, from the display device, display luminance information in a case where the display device performs display; and notifying, by an information processing unit, a viewer, who views the content, of information based on the video luminance information and the display luminance information via the display device.

10 . A non-statutory recording medium storing a program causing a computer of a content processing device, which causes a display device connected thereto to output content, to execute the steps of:
acquiring video luminance information included in the content from service information included in the content; acquiring, from the display device, display luminance information in a case where the display device performs display; and notifying a viewer, who views the content, of information based on the video luminance information and the display luminance information via the display device.
