## Abstract

A digital broadcast receiving apparatus capable of executing a function with a higher added value is provided. A broadcast receiving apparatus configured to receive contents includes: a receiving unit configured to receive the contents; an interface via which the contents received by the receiving unit is outputted; a control unit configured to control an output state of the contents from the interface. In this case, the control unit is configured to determine the output state of the contents from the interface in accordance with a combination of control information indicating a copy control state of the contents, control information for specifying necessity or not of protection when to output the contents, information indicating resolution of video of the contents, and information indicating transmission characteristics of video of the contents, which are received by the receiving unit together with the contents.

## Claims

### Claim 1

A video processing method in content receiver, which receives content data of digital broadcasting, the video processing method comprising:
receiving, by a broadcast receiver, broadcasting data, the broadcasting data containing i) encoded video data regarding broadcasting programs of the digital broadcasting, ii) event schedule information, iii) a first type of transmission characteristics information indicating in a program unit whether the encoded video data corresponds to High Dynamic Range (HDR) or not, and iv) a second type of transmission characteristics information indicating in a unit different from the program unit whether the encoded video data corresponds to HDR or not;
decoding, by a video decoder, the encoded video data received by the broadcast receiver to reproduce video information;
converting, by a video converter, transmission characteristics of the video information reproduced by the video decoder at least from Standard Dynamic Range (SDR) to HDR;
displaying, by a display, i) a video based on the video information reproduced by the video decoder, and ii) an electronic program guide created based on the event schedule information received by the broadcast receiver; and
controlling, by a controller, switching timing of video processing by the video converter,
wherein when receiving both of the first type of the transmission characteristics information and the second type of the transmission characteristics information for video data: i) the second type of the transmission characteristics information is received by the broadcast receiver in a state where the second type of the transmission characteristics information is included in an encoded video stream for the video data; ii) the first type of the transmission characteristics information is received by the broadcast receiver in a state where the first type of the transmission characteristics information is not included in the encoded video stream for the video data; and iii) the first type of the transmission characteristics information is received earlier than the second type of the transmission characteristics information,
wherein the switching timing of video processing by the video converter is controlled to become later than switching timing of decoded video by the video decoder, in response to a change of indication of the first type of the transmission characteristics information for the encoded video from HDR to SDR, and
wherein the switching timing of video processing by the video converter is controlled to become earlier than switching timing of decoded video by the video decoder, in response to a change of indication of the first type of the transmission characteristics information for the encoded video from SDR to HDR.

### Claim 2

A video processing method in content receiver, which receives content data of digital broadcasting, the video processing method comprising:
receiving, by a broadcast receiver, broadcasting data, the broadcasting data containing i) encoded video data regarding broadcasting programs of the digital broadcasting, ii) event schedule information, iii) a first type of transmission characteristics information indicating in a program unit whether the encoded video data corresponds to High Dynamic Range (HDR) or not, and iv) a second type of transmission characteristics information indicating in a unit different from the program unit whether the encoded video data corresponds to HDR or not;
decoding, by a video decoder, the encoded video data received by the broadcast receiver to reproduce video information;
converting, by a video converter, transmission characteristics of the video information reproduced by the video decoder at least from Standard Dynamic Range (SDR) to HDR;
displaying, by a display, i) a video based on the video information reproduced by the video decoder, and ii) an electronic program guide created based on the event schedule information received by the broadcast receiver; and
controlling, by a controller, switching timing of video processing by the video converter,
wherein when receiving both of the first type of the transmission characteristics information and the second type of the transmission characteristics information for video data: i) the second type of the transmission characteristics information is received by the broadcast receiver in a state where the second type of the transmission characteristics information is included in an encoded video stream for the video data; ii) the first type of the transmission characteristics information is received by the broadcast receiver in a state where the first type of the transmission characteristics information is not included in the encoded video stream for the video data; and iii) the first type of the transmission characteristics information is received earlier than the second type of the transmission characteristics information, and
wherein the switching timing of video processing by the video converter is controlled to become later than switching timing of decoded video by the video decoder, in response to a change of indication of the first type of the transmission characteristics information for the encoded video from HDR to SDR.

### Claim 3

A video processing method in content receiver, which receives content data of digital broadcasting, the video processing method comprising:
receiving, by a broadcast receiver, broadcasting data, the broadcasting data containing i) encoded video data regarding broadcasting programs of the digital broadcasting, ii) event schedule information, iii) a first type of transmission characteristics information indicating in a program unit whether the encoded video data corresponds to High Dynamic Range (HDR) or not, and iv) a second type of transmission characteristics information indicating in a unit different from the program unit whether the encoded video data corresponds to HDR or not;
decoding, by a video decoder, the encoded video data received by the broadcast receiver to reproduce video information;
converting, by a video converter, transmission characteristics of the video information reproduced by the video decoder at least from Standard Dynamic Range (SDR) to HDR;
displaying, by a display, i) a video based on the video information reproduced by the video decoder, and ii) an electronic program guide created based on the event schedule information received by the broadcast receiver; and
controlling, by a controller, switching timing of video processing by the video converter,
wherein when receiving both of the first type of the transmission characteristics information and the second type of the transmission characteristics information for video data: i) the second type of the transmission characteristics information is received by the broadcast receiver in a state where the second type of the transmission characteristics information is included in an encoded video stream for the video data; ii) the first type of the transmission characteristics information is received by the broadcast receiver in a state where the first type of the transmission characteristics information is not included in the encoded video stream for the video data; and iii) the first type of the transmission characteristics information is received earlier than the second type of the transmission characteristics information, and
wherein the switching timing of video processing by the video converter is controlled to become earlier than switching timing of decoded video by the video decoder, in response to a change of indication of the first type of the transmission characteristics information for the encoded video from SDR to HDR.
