Patent application numberDescriptionPublished
20110228856VIDEO ENCODER/DECODER, METHOD AND COMPUTER PROGRAM PRODUCT - A video encoder/decoder device, method, and computer program product combine to enhance entropy encoding by using different calculation approaches for assessing costs of using different encoding modes for a video encoding. Moreover, frames in a sequence, and/or sub-frames within a frame may have lowest cost coding modes selected using different cost calculation approaches. One exemplary cost calculation is SAD and another is SSD. A net effect is better subjective video quality for a given bitrate, with reduced encoder complexity, especially when recognizing the lesser amount of computational resources required to support SAD as opposed to SSD.09-22-2011

20090116550VIDEO COMPRESSION SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT USING ENTROPY PREDICTION VALUES - A method, apparatus and computer program product is configured to perform entropy coding of quantized transform coefficients when for some reason no pixels are available for prediction. Different variable length code tables are used for when pixel value predictions are available, or not. If not available, a fixed value is inserted in a block of pixels which is used as the prediction block for deriving the residual block, which in turn are transformed and quantized. A special variable length code table is then used to represent low frequency coefficients of the quantized transform coefficients.05-07-2009
20090122861INTEGER TRANSFORM FUNCTION FOR VIDEO COMPRESSION SYSTEMS - The present invention is directed to video coding/decoding and discloses a method for transforming to/from transform coefficients and residual pixel data in moving pictures by a set of semi-orthonormal basis vectors. The basis vectors are derived from conventional DCT or KTL matrixes, but relaxes to some extend the requirements for orthogonality, norm equality and element size limitation. In this way the present invention provides improved coding efficiency and lower complexity compared to previously used integer transforms.05-14-2009
20090161974VARIABLE LENGTH CODING (VLC) METHOD AND DEVICE - A method for representing video data related to a macroblock of a video image in a coding procedure wherein certain, video data or combinations of video data is represented in predefined events associated with indexed positions in a Variable Length Code (VLC) table including codes assigned to each indexed position, including: determining, with a processor, that a first event among said predefined events occurs during the coding procedure; coding, with the processor, the first event with a code assigned to a position x in the VLC table being associated with the first event, the VLC table being stored in a memory device; determining, with the processor, whether x>0, wherein 0 denotes a position at a top of the VLC table; and rearranging, with the processor, the VLC table by associating a second event currently associated with a position x−1 with the position x, and associating the first event with the position x−1.06-25-2009
20090323827METHOD RELATED TO NOISE REDUCTION - A pre-processing of video data before coding and transmission, for a method for noise reduction in High-Density video images. A low implementation-complex filter filters raw pixel data output of a video camera with a low pass property for both spatial and temporal noise and the filter is adapted based on the high frequency content of the picture, leaving most of the image content unaffected by the filtering process.12-31-2009

20100166059METHOD AND APPARATUS FOR VIDEO COMPRESSION - A unified solution to coding/decoding of different video formats such as 4:2:0, 4:2:2 and 4:4:4 is provided. A method of video coding includes transforming a first m×n macro block of residual chrominance pixel values of moving pictures by a first integer-transform function generating a corresponding second m×n macro block of integer-transform coefficients, further transforming DC values of the integer-transform coefficients by a second integer-transform function to generate a third block of integer-transformed DC coefficients. The method further includes generating the second m×n macro block of integer-transform coefficients by utilizing a k×k integer-transform function on each k×k sub-block of the first m×n macro block, wherein n and m are each a multiple of k, and generating the third block of coefficients by utilizing a second ixj integer-transform function on the DC values resulting in a (m/k)×(n/k) third block of integer-transformed DC coefficients.07-01-2010
