When the video units are switched, in fast forward reproduction, as an elapsed jump time duration, a difference between a reproduction time of a last displayed picture in a source video unit and an end time of the source video unit is calculated (S104), then, as a remaining jump time duration, a value is calculated by subtracting the calculated elapsed jump time duration from the jump time duration corresponding to the designated speed (S105), then, as a reproduction start time, a time is calculated by adding the calculated remaining time duration to a start time of a destination video unit (S106), and the video is reproduced from the reproduction start time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video reproduction method and video reproduction device","description":"Provided is a video reproduction method with a less difference between a target speed and an actual speed, when fast forward reproduction or fast rewind reproduction is performed on reproduction units","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8498521","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.
