This invention discloses a wireless low-latency video receiver line block compression and linked recovery system, belonging to the field of wireless video transmission and display technology. After decoding at the receiver, the system performs line block-level visual lossless compression and storage of the image, replacing traditional whole-frame storage. The display side reads the compressed line blocks on demand, decompresses them, and stores them in a small-capacity display buffer. Combining innovative technologies such as adaptive line block compression strategies, intelligent prefetching mechanisms, multi-level error detection, dynamic buffer management, and frame rate linkage control, the system significantly reduces display latency and improves its recovery capability and display smoothness under wireless channel interference. While ensuring visual losslessness, it can reduce display latency by more than 50% and storage bandwidth requirements by more than 65%, making it suitable for latency-sensitive applications such as wireless projection, remote control, and video conferencing.
