The moving image coding method includes: a step of determining a continuous playback section that is a group of partial sections and is subject to continuous playback, in the video stream (S5301 to S5303); a step of coding the first and second moving images in the partial sections constituting the continuous playback section, under a constraint that prevents a threshold from being changed in the continuous playback section, the threshold being used for a transparency process by a luminance key in the overlaying (S5304); and a step of generating management information including flag information which indicates that the threshold is fixed in the continuous playback section (S5305)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Moving image coding method, moving image coding device, moving image recording method, recording medium, moving image playback method, moving image playback device, and moving image playback system","description":"A moving image coding method that can prevent playback discontinuity without an increase in processing load during playback is provided.The moving image coding method codes a video stream that include","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526797","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.
