Abstract
A method for real-time monitoring image transmission. First, the frame is divided into a plurality of sub-blocks and numbered in order. Then, a sub-block with variation is designated as a start sub-block, and sub-blocks adjacent to the start sub-block are searched and the sub-blocks with variation are grouped to generate at least one variant sub-block set, in which the variant sub-blocks in the set are connected to each other and form a rectangle. Thereafter, the compressed variant sub-block set and the corresponding numbers of each variant sub-block in the set are transmitted to the server. Afterward, the server replaces corresponding sub-blocks having the same numbers in an original frame with the received variant sub-blocks.
