Patent ID: 7260642

Claim:
A method for real-time monitoring image transmission for used in a network system connecting a server and a client, comprising the steps of: gathering a first frame and a second frame which is subsequent to the first frame from the client, and respectively dividing the first frame and the second frame into a plurality of sub-blocks, in which each sub-block has a corresponding number; detecting a variant sub-block from the sub-blocks in the second frame by comparing contents of the sub-blocks having the same number in the first frame and the second frame, and assigning the variant sub-block as a start sub-block; performing at least one determination rule on sub-blocks in a specified region of the start sub-block in the second frame, so as to generate a variant sub-block set including the start sub-block and sub-blocks that conform to the determination rule; compressing the variant sub-block set; and transmitting the compressed variant sub-block set to the server.
