Abstract: A recording medium is a disc-shaped recording medium having a plurality of recording layers, in which a video stream is recorded on the plurality of recording layers. Part of the video stream is recorded up to a first recording position on a first recording layer of the plurality of recording layers. A remaining part of the video stream is recorded from a second recording position of a second recording layer adjacent to the first recording layer. The video stream is seamlessly connected between the first recording position and the second recording position, and a first distance between the first recording position and the second recording position in the radial direction of the recording medium is smaller than a second distance in the radial direction regarding which a jump is permitted in seamless connection within a same recording layer.

Abstract: A transmission method includes: dividing a picture into a plurality of regions; generating a plurality of pieces of encoded data that respectively correspond to the plurality of regions by encoding the plurality of regions such that each of the plurality of regions can be decoded independently; packetizing by storing the generated plurality of pieces of encoded data in a plurality of packets; and a transmitting step of transmitting the plurality of packets. In the packetizing step, the plurality of pieces of encoded data are stored in the plurality of packets such that pieces of encoded data for different regions are not stored in a single packet. By this, workload for generation of decoding target data is reduced.

Abstract: Provided is a display method of displaying, on a display device, video of video data where luminance of video is defined by a first EOTF (Electro-Optical Transfer Function) corresponding to HDR (High Dynamic Range). The method includes: acquiring the video data; performing first conversion where the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, where, with regard to a second EOTF that is part of the first EOTF and is the part of a luminance range where the peak luminance indicated by the peak luminance information included in the acquired video data is the maximum luminance, the dynamic range of luminance of the second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF; and displaying the video on the display device using the result of the first conversion.
