[0097] (Configuration Example of First Embodiment of Recording and Reproducing System)

[0098] figure 1 is a diagram showing a configuration example of the first embodiment of the recording and reproducing system to which the present technology is applied.

[0099] exist figure 1 The recording and reproducing system in is configured to include a recording device 1 , a reproducing device 2 , and a display device 3 . The playback device 2 and the display device 3 are connected by a high-definition multimedia interface (HDMI: registered trademark) cable 4 . The reproducing device 2 and the display device 3 may be connected by another standard cable, or may be connected by wireless communication.

[0100] The recording device 1 records content, and the reproducing device 2 reproduces the content. Using the optical disc 11, supplying the content of the recording device 1 to the reproducing device 2 is performed. For example, the optical disc 11 is an optical disc on which con...

[0420] (Configuration example of AV stream)

[0421] Figure 36 is a diagram showing a configuration example of an AV stream in the second embodiment of the recording and reproducing system to which the present technology is applied.

[0422] In the second embodiment, as Figure 36 As shown in , tone_mapping_info is not included in the video stream, but is included in the AV stream which is a new stream. That is, according to the second embodiment, not only the video stream of the main video, the audio stream reproduced in synchronization with the video stream of the main video, the video stream of the sub video, the PG stream, the Text-ST stream, and the IG stream, but also a stream of tone_mapping_info Multiplexed to AV stream.

[0423] At least one piece of tone_mapping_info is included in the Tone_map stream which is the stream of tone_mapping_info. Here, tone_mapping_info included in the Tone_map stream is used when reproducing the video stream or the graphics stream ...

[0494] (Configuration of PG stream and IG stream)

[0495] Figure 49 is a diagram showing a configuration example of a display set of a PG stream and an IG stream in the third embodiment.

[0496] In the third embodiment, the tone_mapping_info of the PG stream and the IG stream is not included in the video stream or the Tone_map stream, but is included in the PG stream and the IG stream.

[0497] Specifically, as Figure 49As shown in A, a tone_mapping_info definition segment (TDS), which is a segment of tone_mapping_info for describing subtitles corresponding to one screen, is prepared as a segment of a display set of a PG stream. Such as Figure 49 As shown in B, TDS, which is a segment for describing tone_mapping_info corresponding to a menu button of one screen, is prepared as a segment of a display set of an IG stream.

[0498] In XPDS of PG streams, except Figure 20 In addition to the description of , the number of pieces of tone_mapping_info included in the TDS a...

Abstract

This technology pertains to a playback device, playback method, and recording medium whereby graphics having a high luminance dynamic range can be displayed at an appropriate brightness. A graphics stream is recorded on an optical disc, said graphics stream containing the following: tone_mapping_info containing HDR information indicating the luminance characteristics of HDR graphics having a second luminance range that differs from and is higher than a first luminance range; tone_mapping_info consisting of tone-mapping definition information used when performing a luminance conversion from the HDR graphics to STD graphics having the aforementioned first luminance range; and data representing the HDR graphics. This technology can be applied to a recording medium on which graphics are recorded.

Description

technical field [0001] The present technology relates to a reproducing device, a reproducing method, and a recording medium, and more specifically, to a reproducing device, a reproducing method, and a recording medium capable of displaying graphics with luminance of a wide dynamic range and appropriate luminance. Background technique [0002] As a recording medium of content such as a movie, there is a Blu-ray (registered trademark) disc (hereinafter appropriately referred to as BD). In the prior art, when passing the standard luminance (100nit=100cd / m 2 On the premise of enjoying the contents on the monitor of ), by compressing the dynamic range of the main graphics, it is possible to create graphics such as subtitles included in the BD or menu buttons manipulated by the user. [0003] Graphics as main have a dynamic range equal to or greater than that displayable on a standard luminance monitor. When compressing the dynamic range of the main graphic, of course the dynami...
