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 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.
