Abstract: RECORDING MEDIUM, PLAYBACK METHOD, AND PLAYBACK DEVICE Recorded in a recording medium are a video stream of standard-luminance range, and a video stream of high-luminance range that is a broader luminance range than the standard-luminance range, which are used selectively in accordance with a playback environment, a subtitle stream of the standard- luminance range, and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment, and a playlist file storing playback control information of content, playlist file including a management region where the playback control information relating to a main stream is stored, and an extended region. The management region stores first playback control information specifying that a video stream of the high-luminance range and a subtitle stream of the high-luminance range are to be played in combination. The extended region stores second playback control information specifying that a video stream of the standard-luminance range and a subtitle stream of the standard-luminance range are to be played in combination.

Abstract: A playback method of a playback device that plays video streams recorded in a recording medium, in which are recorded one or more video streams including at least one of an HDR stream of which a dynamic range of luminance of video corresponds to a high dynamic range (HDR), and an SDR stream of which a dynamic range of luminance of video corresponds to a standard dynamic range (SDR) that is narrower than HDR, and identification information indicating whether or not the HDR stream is included in the one or more video streams. The playback method includes: reading the identification information from the recording medium; acquiring playback capability information indicating whether or not the playback device can play the HDR stream, and display capability information indicating whether or not a display device connected to the playback device can display the HDR video; and deciding a video stream for playback out of the one or more video streams, in accordance with the identification information that has been read out, the acquired playback capability information and the acquired display capability information.

Abstract: Data including a digital stream obtained by encoding video information is recorded in a recording medium. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. The data includes a digital stream having real-time attributes and a data file having non-real-time attributes. The data file to be read in during playback of the digital stream is recorded in, of the first recording region and the second recording region, the same recording region as the recording region where the digital stream is recorded.

Abstract: In a playback method of a playback device that plays a system stream file including encrypted video information, the system stream file includes a first segment in which is repeated a first data unit that can be decrypted using a first decryption key that the playback device has and a second data unit of the same data size as the first data unit but cannot be decrypted by the first decryption key, and a second segment which can all be decrypted using a second decryption key that differs from the first decryption key. The playback method reads the system stream file, and performs conversion processing to convert the system stream file that has been read out into a post-conversion system stream, in which the second data unit in the first segment in the system stream file that has been read out is replaced with a plurality of continuous invalid packets, and outs the post-conversion system stream.

Abstract: A playlist file for controlling playback of a VOB stream file is recorded in a recording medium. A CombiExt_for_Cell() and Combi() indicating combinations of elementary streams that each can be played at the same time in the same Cell are described in the playlist file. Elementary streams that can be played at the same time as SDR video are listed in the CombiExt for_Cell(), and elementary streams that can be played at the same time as HDR video are listed in Combi(). The number of elementary streams of a predetermined type listed in CombiExt_for_Cell() and the number of elementary streams of the predetermined type listed in Combi() are each equal in the same Cell.

Abstract: A recording medium according an aspect of the present disclosure has recorded therein a main video stream where a main video has been encoded, and a sub-video stream where a sub-video, that is to be superimposed on the main video and displayed, has been encoded. The sub-video stream includes bitmap data indicating a design of the sub-video and palette data specifying the display color of the design. The palette data includes first palette data for a first luminance dynamic range (SDR), and second palette data for a second luminance dynamic range (HDR) that is broader than the first dynamic range.
