Method And System For Rate Control In A Video Encoder
US Patent:
2006023, Oct 26, 2006
Filed:
Apr 25, 2005
Appl. No.:
11/113705
Inventors:
Ashish Koul - Cambridge MA, US
Douglas Chin - Haverhill MA, US
Stephen Gordon - North Andover MA, US
Douglas Chin - Haverhill MA, US
Stephen Gordon - North Andover MA, US
International Classification:
H04N 11/04
US Classification:
375240010
Abstract:
Described herein is a method and system for rate control in a video encoder. The method and system can use relative persistence and intensity of video data in a macroblock to classify that macroblock. On a relative basis, a greater number of bits can be allocated to persistent video data with a low intensity. The quantization is adjusted accordingly. Adjusting quantization prior to video encoding enables a corresponding bit allocation that can preserve perceptual quality.
Method And System For Motion Estimation In A Video Encoder
US Patent:
2006022, Oct 5, 2006
Filed:
Apr 1, 2005
Appl. No.:
11/096825
Inventors:
Bo Zhang - Westford MA, US
Stephen Gordon - North Andover MA, US
Stephen Gordon - North Andover MA, US
International Classification:
H04N 11/02, H04N 7/12, H04N 11/04, H04B 1/66
US Classification:
375240160, 375240120, 375240240, 375240210
Abstract:
Described herein is a method and system for motion estimation in a video encoder. There are two parts to the motion estimation. Coarse motion estimation generates a set of motion vectors for a current picture and at least one reference picture. Typically, coarse motion estimation operates on sub-sampled pictures. Fine motion estimation can refine coarse motion estimation results by searching interpolated video data in a region defined by the motion vectors from the coarse motion estimation.
Method And System For A Parameterized Multi-Standard Deblocking Filter For Video Compression Systems
US Patent:
2012013, May 31, 2012
Filed:
Aug 16, 2011
Appl. No.:
13/210541
Inventors:
Stephen Gordon - North Andover MA, US
International Classification:
H04N 7/26
US Classification:
37524025, 375E07027
Abstract:
In a video processing system, a method and system for a parametrized multi-standard deblocking filter for video compression systems are provided. A multi-standard deblocking filter may be configured to filter a reconstructed output stream based on a selected standard mode of operation. The configured multi-standard deblocking filter may be utilized in a decoder and/or in a decoding portion of an encoder. Filtered or unfiltered reconstructed pictures may be selected for storage in a picture buffer before further processing. Filtered or unfiltered reconstructed pictures may be selected for display in a decoder or for intra-coding and inter-coding processing in the decoding portion of the encoder. Filter parameters in the multi-standard deblocking filter may be configured based on a set of side information and the selected standard mode of operation.
Method And System For Dynamic Selection Of Transform Size In A Video Decoder Based On Signal Content
US Patent:
7894530, Feb 22, 2011
Filed:
Apr 15, 2005
Appl. No.:
11/107138
Inventors:
Stephen Gordon - North Andover MA, US
Douglas Chin - Haverhill MA, US
Douglas Chin - Haverhill MA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04N 7/12
US Classification:
37524018, 37524025
Abstract:
In a video processing system, a method and system for dynamic selection of transform size in a video decoder based on signal content are provided. For high profile mode video decoding operations, inverse transform sizes may be selected from a 4×4 or an 8×8 inverse transform size based on a transform size syntax element generated by the encoding operation and transmitted as part of the encoded video information bit stream. A set of rules is defined for selecting the transform size based on a macroblock type and a size of the macroblock type of a received macroblock in a video decoder. Dynamic selection of transform size may be performed on intra-coded macroblocks, inter-coded macroblocks, and/or direct mode inter-coded macroblocks.

Darren Neuman - Palo Alto CA, US
International Classification:
H04N 11/02, H04N 7/12, H04N 11/04, H04B 1/66
US Classification:
375240250, 375240010
Abstract:
A system and method for processing video information. Various aspects of the present invention may comprise receiving encoded video information at a video processing system. An indication of utilization for at least one system resource of the video processing system may be determined. Such a system resource may, for example, comprise memory access bandwidth. A decoding strategy of a plurality of decoding strategies may be identified based, at least in part, on the determined indication(s) of utilization. The identified decoding strategy may, for example and without limitation, comprise a decoding strategy that does not conform to the encoding standard with which the encoded video information was encoded. The encoded video information may then be decoded according to the identified decoding strategy.
Method And System For Generating A Transform Size Syntax Element For Video Decoding
US Patent:
8116374, Feb 14, 2012
Filed:
May 2, 2005
Appl. No.:
11/119615
Inventors:
Stephen Gordon - North Andover MA, US

Douglas Chin - Haverhill MA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04N 7/12
US Classification:
37524012
Abstract:
In a video processing system, a method and system for generating a transform size syntax element for video decoding are provided. For high profile mode video decoding operations, the transform sizes may be selected based on the prediction macroblock type and the contents of the macroblock. A set of rules may be utilized to select from a 4×4 or an 8×8 transform size during the encoding operation. Dynamic selection of transform size may be performed on intra-predicted macroblocks, inter-predicted macroblocks, and/or direct mode inter-predicted macroblocks. The encoding operation may generate a transform size syntax element to indicate the transform size that may be used in reconstructing the encoded macroblock. The transform size syntax element may be transmitted to a decoder as part of the encoded video information bit stream.
