The MISR holds a frame signature for the frame region of the video frame while receiving a frame end signal. The MSSB stores a current frame signature held by the MISR after receiving the frame end signal. The MSSB also stores a reference frame signature. A display processing circuit includes the fault detection circuit. An integrated circuit includes the display processing circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for detecting faults in video frames of video sequence","description":"A fault detection circuit for detecting faults in a video sequence includes a multiple input signature register (MISR) with a linear feedback shift register (LFSR) that receives pixel data for pixels ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9665934","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.
