The first communication device also transmits speed maps enabling the second communication device to thereby apply an image enhancement operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for transmitting video data over a powerline communications transmission channel","description":"For transmitting video data over a powerline communications transmission channel, a first communication device: obtains video data in the form of a succession of uncompressed images; determines the ca","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749015","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.
