The IT module performs 4×4 Inverse Integer transform for AVC for MPEG-2 operations on a given macro block (MB) and all its sub blocks. The IT is the third module in the data flow pipeline of a video decoder, the first two being a variable length decoder (VLD) and an inverse quantizer (IQ). The IT module gets its inputs from IQ module and feeds its processed output to a Motion compensation unit/intra-prediction (MCU-IP) module, thus reconstructing the video picture."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AVC I—PCM data handling and inverse transform in a video decoder","description":"An Inverse Transform (IT) conforming to MPEG AVC I_PCM that offers better video image quality than the MPEG-2/H.263 based video decoders and real time motion picture processing at 30 frames/seconds is","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537889","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.
