The map information includes playback start time information, start position information, and size information. The playback method includes reading out the map information and the bitrate information, and determining the stipulated data size in accordance with the bitrate information. The playback method also includes acquiring the picture from the video stream based on the result of the determination, and the start position information and the size information included in the map information that has been read out. The method further includes decoding and playing the acquired picture, wherein the stipulated data size differs between 2K resolution of the video stream and 4K resolution of the video stream."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Recording medium, playback method, and playback device","description":"A playback device and playback method are provided for reading out and playing content from a recording medium in which are recorded a video stream that is encoded video information, map information, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10497400","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
