Research Paper
Core Innovation
This paper introduces WVSC-D, which shifts video coding from pixel-level to semantic-level representations, significantly reducing data transmission needs. It replaces traditional motion vectors with a reference semantic frame and employs a novel two-stage conditional diffusion process for multi-frame compensation, enhancing video reconstruction quality and bandwidth efficiency.
Why It Matters
Wireless video transmission often suffers from high bandwidth demands and inefficient pixel-level coding. By encoding videos semantically and reducing motion vector overhead, this approach lowers communication costs while maintaining video quality. It can scale to support real-time video streaming and communication in bandwidth-constrained wireless networks, benefiting mobile and IoT applications.

Research Paper Overview
Wireless Video Semantic Communication with Decoupled Diffusion Multi-frame Compensation
Summary
This paper proposes WVSC-D, a wireless video semantic communication framework that encodes video frames at the semantic level rather than pixel level, reducing communication overhead by substituting motion vectors with a reference semantic frame. It uses a two-stage conditional diffusion process for multi-frame compensation at the receiver, improving bandwidth efficiency and video quality, achieving about 1.8 dB PSNR gain over prior DL-based methods.
