| 20090219986 | HIERARCHICAL VIDEO ANALYSIS-BASED REAL-TIME PERCEPTUAL VIDEO CODING - A system for encoding a video stream into a processed video signal that includes at least one image. The system includes a downscaling module, a partitioning module, a rate control module, and an encoder section. The downscaling module receives the video stream and produces a downscaled video stream. A partitioning module, including a region detection module, receives the downscaled video stream and detects a pattern of interest in the at least one image. The partitioning module is operable to partition the at least one image based on the detected pattern of interest. The 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. The encoder section, coupled to the rate control module, receives the video stream and generates the processed video signal. | 09-03-2009 |
| 20110080944 | REAL-TIME VIDEO TRANSCODER AND METHODS FOR USE THEREWITH - A transcoder includes a direct transcoder that generates a first portion of a transcoded video stream by reusing a plurality of encoding parameters of a compressed video stream. A cascaded transcoder generates a second portion of the transcoded video stream by decoding the compressed video stream into video data in an uncompressed video format and by re-encoding the video data. A transcoding decision generator generates a transcoding indicator, based on the compressed video stream. A switching module selects the direct transcoder for the first portion of the transcoded video stream and the cascaded transcoder for the second portion of the transcoded video stream, based on the transcoding indicator. | 04-07-2011 |
