Patent ID: 8780988

Claim:
A system for encoding a video stream into a processed video signal, the video stream including at least one image, the system comprising: a scene change detection module that receives the video stream, that detects a scene change to a new scene of the video stream and that produces a temporal synchronization signal in response thereto; a downscaling module that receives the video stream and produces a downscaled video stream by a temporal downscaling and a spatial downscaling of the video stream; a partitioning module including a detection module that receives the downscaled video stream and detects a pattern of interest in the at least one image based on the downscaled video stream, the partitioning module configured to partition the at least one image based on the detected pattern of interest, and to trigger repartition of the downscaled video stream when the temporal synchronization signal indicates the new scene; a rate control module that receives an output from the partitioning module and produces an encoder control signal dependent on the output from the partitioning module; and an encoder section, coupled to the rate control module that receives the video stream and generates the processed video signal.
