20130113880 | High Efficiency Video Coding (HEVC) Adaptive Loop Filter - A High Efficiency Video Coding (HEVC) receiver is provided with a method for adaptive loop filtering. The receiver accepts digital information representing an image, and adaptive loop filter (ALF) parameters with no DC coefficient of weighting. The image is reconstructed using the digital information and estimates derived from the digital information. An ALF filter is constructed from the ALF parameters, and is used to correct for distortion in the reconstructed image. Typically, the receiver accepts a flag signal to indicate whether the DC coefficients have been transmitted or not. In other aspects, center luma coefficients are estimated from other coefficients, and the use of k values is simplified. | 05-09-2013 |
20130114681 | VIDEO DECODER WITH ENHANCED SAMPLE ADAPTIVE OFFSET - A decoder decodes video received in a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and a plurality of offset type characteristics.
