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 (14)

1. A broadcast receiving apparatus for receiving broadcasting data of digital broadcasting, the broadcast receiving apparatus comprising:

a broadcast receiver receives broadcasting data, the broadcasting data containing encoded program video data regarding broadcasting programs of the digital broadcasting, High Dynamic Range (HDR) information, information related to estimated delay time, and event schedule information, wherein the encoded program video data includes first encoded program video data of a live broadcasting program or second encoded program video data of a non-live broadcasting program, the estimated delay time indicates estimated delay time between a broadcast station server and the broadcast receiving apparatus, the information related to estimated delay time is included in Transmission and Multiplexing Configuration Control (TMCC) region outside Type Length Value (TLV) multiplexing stream, and the HDR information indicates whether the first encoded program video data or the second encoded program video data is compatible with enlargement of a luminance range or not and also indicates a type of gamma correction subjected to each of the first encoded program video data and the second encoded program video data;

a video decoder decodes the encoded program video data received by the broadcast receiver to reproduce program video information;

a display displays an electronic program guide created on the basis of the event schedule information received by the broadcast receiver; and

a controller that:

controls correcting of a system clock based on the information related to the estimated delay time which is acquired from the TMCC region outside the TLV multiplexing stream,

controls switching timing of video processing of a video color gamut conversion unit to become later than switching timing of decoded video from the video decoder in response to switching from HDR video contents to Standard Dynamic Range (SDR) video contents,

controls switching timing of video processing of the video color gamut conversion unit to become earlier than switching timing of decoded video from the video decoder in response to switching from SDR video contents to HDR video contents, and

wherein in a case where the display is compatible with the type of the gamma correction indicated by the HDR information, the controller controls the display to display the electronic program guide including a symbol, characters, or a mark indicating that a program corresponding to the HDR information can be displayed with correct luminance representation.

2. The broadcast receiving apparatus according to claim 1 , wherein the controller refers to the HDR information, and control the display so as to display the symbol, the characters, or the mark at a position corresponding to the encoded program video data for the first encoded program video data of the live broadcasting program or the second encoded program video data of the non-live broadcasting program in the electronic program guide information in a case where the encoded program video data corresponds to the enlargement of the luminance range, each of the symbol, the characters, and the mark indicating that the program is compatible with the enlargement of the luminance range.

3. The broadcast receiving apparatus according to claim 1 , wherein the controller controls the display so as to display the symbol, the characters, or the mark at a position corresponding to the encoded program video data for the first encoded program video data of the live broadcasting program or the second encoded program video data of the non-live broadcasting program in the electronic program guide information in a case of indicating that a form of the encoded program video data described in the HDR information corresponds to the enlargement of the luminance range.

4. The broadcast receiving apparatus according to claim 1 , wherein the controller controls the display so as to display the symbol, the characters, or the mark at a position corresponding to the encoded program video data for the first encoded program video data of the live broadcasting program or the second encoded program video data of the non-live broadcasting program in the electronic program guide information in a case where the maximum value of luminance, to which the encoded program video data described in the HDR information corresponds, is a predetermined value or more.

5. The broadcast receiving apparatus according to claim 1 , wherein the controller controls the display so as to display the symbol, the characters, or the mark at a position corresponding to the encoded program video data of a non-live broadcasting program in the electronic program guide information in a case where editing equipment used for editing of the encoded program video data described in the HDR information corresponds to the enlargement of the luminance range.

6. The broadcast receiving apparatus according to claim 1 , wherein the controller controls a presentation processor not to display the symbol, the characters, or the mark at a position corresponding to the encoded program video data in the electronic program guide information in a case where the display is not configured to deal with the enlargement of the luminance range even though the encoded program video data corresponds to the enlargement of the luminance range.
