The first packet data is supplied to one port of a decoder through one switch unit, while the second packet data is supplied to the other port of the same decoder through the other switch unit. The decoder checks on the first packet data and the second packet data provided with the same serial number, and thereby monitors whether or not an error occurs in the first packet data and the second packet data. Then, the decoder decodes normal packet data selected from the first packet data and the second packet data, and outputs the decoded data to a video switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video playback device and video playback method","description":"According to an embodiment, a memory creates first packet data and second packet data which are identical to the first packet data, and adds the same serial number to the first packet data and the sec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467667","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.
