Disclosed in the present disclosure is a video image coding method. The method includes: dividing an image frame to be coded into a plurality of sub-blocks, and assigning coordinates to each sub-block; calculating a hash value corresponding to an i-th sub-block according to a content of the i-th sub-block; performing a search in a first hash table by using the hash value corresponding to the i-th sub-block; in response to the coordinates of the first reference block being valid, acquiring a content of the first reference block according to the coordinates of the first reference block, and comparing the content of the first reference block with the content of the i-th sub-block; and in response to the content of the first reference block being consistent with the content of the i-th sub-block, performing Intra Block Copy (IBC) coding on the i-th sub-block.

Provided is a dynamic Huffman encoding method based on a sorting network. Compared with traditional dynamic Huffman coding solutions, the method implements sorting on the basis of the sorting network, therefore the sorting process is not only stable, but also may ensure a stable sorting result; and moreover, sorting steps and related operations are simpler, thereby greatly simplifying the sorting and iteration processes, and thus the sorting efficiency is higher. In addition, the sorting process better facilitates program implementation and transplantation, and implementation of hardware and software may achieve good effects. In addition, the present disclosure further provides a dynamic Huffman coding apparatus and device based on a sorting network, and a readable storage medium, and the technical effects thereof correspond to the technical effects of the above method.
