Abstract
Official abstract text for this publication.
Recorded in a recording medium is a video stream, map information, and bitrate information of the video stream. The map information includes size information indicating data size of a section where a picture is recorded in the video stream, based on a predetermined stipulated data size. The stipulated data size differs in accordance with the bitrate information.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-transitory recording medium in which are recorded a video stream that is encoded video information, and map information, wherein the map information includes playback start time information of a picture (PTS) that is included in the video stream and is independently decodable, start position information (I_Start) indicating a data start position of the picture, and size information (I_End) indicating a data size of a section where the picture is recorded, based on a predetermined stipulated data size, wherein the stipulated data size of 4K resolution of the video stream is larger than the stipulated data size of 2K resolution of the video stream. 2. A non-transitory recording medium in which are recorded a multiplexed digital stream that includes an encoded video information, and map information, wherein the map information includes playback start time information of a picture that is included in the encoded video stream and is independently decodable, start position information indicating a data start position of the picture in the multiplexed digital stream, and size information (I_MUX_SIZE) indicating a data size of the picture in the multiplexed digital stream is recorded based on a predetermined stipulated data size, wherein the stipulated data size of 4K resolution of the video stream is larger than the stipulated data size of 2K resolution of the video stream.
