摘要
A versatile video coning method is provided for an electronic device. The method includes obtaining a video signal; partitioning the video signal into a plurality of coding blocks; generating a residual coding block from each coding block with or without transformation and quantization; splitting the residual coding block into a plurality of sub-blocks and each sub-block into a plurality of pixels; entropy coding a residual symbol level at each pixel in the residual coding block; and outputting a bitstream including entropy coded residual symbol levels. Entropy coding the residual symbol level at each pixel in the residual coding block includes context modeling of the residual symbol level of the pixel in a transform skip mode based on context information of at least three neighboring pixels of the pixel including a first pixel on the left, a second pixel on the above, and a third pixel on the left-above diagonal.
