According to an embodiment of the present disclosure, the motion-constrained encoding method includes: limiting a motion prediction range based on a format and a size of an image; and predicting motion vectors regarding tiles constituting the image, based on the limited motion prediction range. Accordingly, a tile-based streaming service is possible through motion-constrained AV1 encoding of an ultra-high definition image (360 VR image or panorama image). In addition, a consumer electronic device is enabled to integrate and decode segmented images by using a single standard AV1 decoder."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motion-constrained AV1 encoding method and apparatus for tiled streaming","description":"There is provided a motion-constrained AV1 encoding method and apparatus for tile-based streaming of an ultra-high definition image, which encodes an image such that the image can be decoded by integr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290714","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.
