The present invention provides a data processing method, system and storage medium suitable for image transmission. The method includes: obtaining a high-definition video image frame by an encoder of the sender; cutting the high-definition video image of the current frame into m small image blocks , and calculate the corresponding unique fingerprint data for each small image block; and compare the fingerprints with the small image blocks at the same position of the previous frame of high-definition video image; screen out the small image blocks with inconsistent fingerprint comparisons and perform data encoding processing to obtain Multiple coded data, and sent to the receiver; the receiver's decoder receives multiple coded data and decodes and restores the corresponding small image block; judges whether the small image block is complete, if not, from the previous frame of high-definition video The image finds out the small image blocks corresponding to the vacant positions and completes them; stitches the completed small image blocks into a complete high-definition video image and displays it. The invention reduces the delay time of the video frame to ensure the real-time performance of the video frame.
Description
technical field [0001] The technical field of video image coding and decoding of the present invention, in particular, relates to a data processing method, system and storage medium suitable for image transmission. Background technique [0002] At present, high-definition video application scenarios have been widely used, and 4K, 8K, and even higher resolutions are gradually becoming popular. In scenarios such as live event broadcasting, rebroadcasting, remote control of smart wearable devices, and cloud games, high-resolution and low-latency video games are required. Supported by real-time image transmission technology. [0003] Taking a 2K resolution video as an example, the video image size of each frame is 2560*1440, and without any compression coding, the size is 2560*1440*3*8 / 8 / 1024 / 1024=10.547M. If the acquisition and playback is performed at a speed of 60 frames per second, the amount of data generated per second will reach 10.547*60=632.8M. Therefore, encoding and...
