RECEPTION DEVICE, BROADCAST SYSTEM, RECEPTION METHOD, AND PROGRAM
First Claim
1. A reception device comprising:
- a service information processing unit that acquires, from service information of content, current information that indicates luminance information of a video at a current time point and preannouncement information that indicates luminance information of the video after a given time from the current time point;
a level control unit that, when a luminance range indicated by the preannouncement information changes from a luminance range of the video at the current time point, changes a luminance range more gently compared to a change of the luminance range; and
a display unit that displays the video in the luminance range defined by the level control unit.

Abstract
A service information processing unit acquires, from service information of content, current information that indicates luminance information of a video at a current time point and preannouncement information that indicates luminance information of the video after a given time from the current time point, a level control unit, when a luminance range indicated by the preannouncement information changes from a luminance range of the video at the current time point, changes a luminance range more gently compared to a change of the luminance range, and a display unit displays the video in the luminance range defined by the level control unit.

7. A broadcast system including a transmission device and a reception device, wherein
the transmission device transmits content and service information of the content that includes current information that indicates luminance information of a video at a current time point and preannouncement information that indicates luminance information of the video after a given time from the current time point, and the reception device includes: -
a service information processing unit that acquires the current information and the preannouncement information from the service information; a level control unit that, when a luminance range indicated by the preannouncement information changes from a luminance range of the video at the current time point, changes a luminance range more gently compared to a change of the luminance range; and a display unit that displays the video in the luminance range defined by the level control unit.

8. A reception method in a reception device, the reception method comprising:
-
acquiring, from service information of content, current information that indicates luminance information of a video at a current time point and preannouncement information that indicates luminance information of the video after a given time from the current time point; and when a luminance range indicated by the preannouncement information changes from a luminance range of the video at the current time point, changing a luminance range, in which the video is displayed, more gently compared to a change of the luminance range.

9. A non-transitory computer readable recording medium storing a program causing a computer of a reception device to execute:
-
acquiring, from service information of content, current information that indicates luminance information of a video at a current time point and preannouncement information that indicates luminance information of the video after a given time from the current time point; and when a luminance range indicated by the preannouncement information changes from a luminance range of the video at the current time point, changing a luminance range, in which the video is displayed, more gently compared to a change of the luminance range.
