Latest Patents

Karl O Lilleyold holds a patent for "Context-adaptive VLC video transform coefficients encoding/decoding methods and apparatuses." This patent describes a method for encoding transform coefficients of sample blocks within a macroblock of a video picture. The encoding process involves adaptively encoding the number of non-zero coefficients before the trailing one coefficients and the number of trailing one coefficients. Additionally, the method allows for the adaptive encoding of the signs of the trailing one coefficients, the level measures of the non-zero coefficients, the total number of zero coefficients interposed among the non-zero coefficients, and the respective run lengths of the zero coefficients. The adaptive encoding can be influenced by neighboring sample blocks, while decoding is performed in an inverse manner.
