Apparatus And Method For High Quality Intra Mode Prediction In A Video Coder
US Patent:
2009027, Nov 5, 2009
Filed:
Apr 30, 2008
Appl. No.:
12/113197
Inventors:
Jian ZHOU - Fremont CA, US
Assignee:
OMNIVISION TECHNOLOGIES, INC. - Sunnyvale CA
International Classification:
H04N 7/32
US Classification:
37524012, 375E07243
Abstract:
A computer readable storage medium has executable instructions to select a plurality of blocks in a video sequence to be coded as intra-coded blocks. Aggregate intra prediction costs are computed for each intra-coded block relative to a corresponding previous intra-coded block. An intra prediction mode is selected for each intra-coded block based on the aggregate intra prediction costs.
Apparatus And Method For Computationally Efficient Intra Prediction In A Video Coder
US Patent:
2009027, Nov 5, 2009
Filed:
Apr 30, 2008
Appl. No.:
12/113202
Inventors:
Jian ZHOU - Fremont CA, US
Assignee:
OMNIVISION TECHNOLOGIES, INC. - Sunnyvale CA
International Classification:
H04N 7/26
US Classification:
37524015, 375E07126
Abstract:
A computer readable storage medium has executable instructions to select a plurality of blocks in a video sequence to be coded as intra-coded blocks. Intra prediction modes are selected for all intra-coded blocks in a macroblock based on original pixels of neighboring blocks. The mode selection of all intra-coded blocks can be conducted in parallel. The intra-coded blocks in the macroblock are predicted with the selected intra prediction modes based on reconstructed pixels of neighboring blocks.

Assignee:
GENERAL INSTRUMENT CORPORATION - Horsham PA
International Classification:
H04J 3/22
US Classification:
370538
Abstract:
A StatMux system and method are provided for efficiently allocating time slots on the transmission channel between bit streams representing video and bit streams representing data. By providing such a system and method, when a decreased number of data bits need to be transmitted, a decreased number of time slots may be allocated for transmitting the data bits and an increased number of time slots may be allocated for transmitting video bits. When a decreased number of video bits needs to be transmitted, a decreased number of time slots may be allocated for transmitting video bits and an increased number of time slots may be allocated for transmitting data bits.

OmniVision Technologies, Inc. - Santa Clara CA
International Classification:
H04N 11/04
US Classification:
37524024, 37524027, 37524028
Abstract:
A computer readable storage medium has executable instructions to select a plurality of macroblocks in a video sequence to be coded as anchor macroblocks, the anchor macroblocks distributed across the video sequence and facilitating random access decoding of a portion of the video sequence. The video sequence is coded into a bit stream. Auxiliary information associated with the anchor macroblocks is generated. The auxiliary information associated with the anchor macroblocks is inserted in a supplementary section of the bit stream.

International Classification:
H04N 7/36
US Classification:
37524016
Abstract:
Methods, systems and computer program products that may improve the efficiency of the video encoding process. Mode decision processing and bit stream packing may be performed in parallel for various frames in a sequence. This reduces the amount of idle time for both the mode decision processing logic and the bit stream packing logic, improving the overall efficiency of the video encoder.

Abstract:
A method and apparatus for selecting a coding mode are described. For example, the method receives at least one block of a signal to be encoded. The method determines a frame vertical pixel difference in the at least one block and determines a field vertical pixel difference in the at least one block. The method then compares the frame vertical pixel difference with the field vertical pixel difference to determine a first coding mode for the at least one block.
