Classification: CPC H | IPC H

Claim 8:
9. A video encoding method, comprising:
obtaining a predicted image block through prediction technologies according to prediction information;
transform units subtracts the predicted image block from a corresponding original image block to obtain a first residual image block;
the first residual image block is transformed and quantized to obtain a quantized block;
writing division information, the prediction information and the quantized block into a bitstream;
performing inverse quantization and inverse transformation on the quantized block to obtain a second residual image block;
generating a reconstructed image block based on the second residual image block and the predicted image block;
performing deblocking filtering on the reconstructed image formed by reconstructed image blocks to obtain a reference image for reference in subsequent frames;
wherein, in the process of writing the quantized block into the bitstream during video encoding, the method according to claim 1 is used for selecting a context model of a quantized coefficient end flag in the quantized block.
