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.
Claims6
A playback device comprising:
- a readout unit that reads out 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, are recorded in a recording medium;
- and
- a playback unit that plays the main video stream and the sub-video stream that have been read out,
- wherein the sub-video stream includes bitmap data indicating a design of the sub-video and palette data specifying a display color of the design,
- and wherein the palette data includes first palette data for a first luminance dynamic range, and second palette data for a second luminance dynamic range that is broader than the first luminance dynamic range.
