Compressed-Domain-Aware VSR Architecture
This research introduces CDA-VSR, a novel online video super-resolution framework leveraging compressed-domain information. Unlike prior methods that only use decoded LR frames, CDA-VSR exploits motion vectors (MVt-1→t), residual maps (Rest), and frame types (FTt) from the bitstream. It features three specialized modules:
- MV-guided Deformable Alignment (MVGDA): Uses motion vectors for efficient coarse alignment and then refines local misalignments with lightweight deformable convolutions initialized by MVs. This handles large motions robustly while learning only residual offsets.
- Residual Map Gated Fusion (RMGF): Generates spatial weights from residual maps to selectively fuse features. It suppresses misaligned regions (high residual values) and emphasizes reliable structures, preventing error propagation.
- Frame-Type-Aware Reconstruction (FTAR): Adaptively allocates computational resources. It uses a high-capacity branch for I-frames to preserve global fidelity and a lightweight branch for P-frames to boost inference speed, balancing accuracy and efficiency.
Unprecedented Speed & Quality
CDA-VSR demonstrates significant advancements in both reconstruction quality and inference speed, crucial for real-time online VSR.
- Superior Quality: On the REDS4 dataset (CRF=18), CDA-VSR achieves 25.81 dB PSNR, surpassing the state-of-the-art TMP by 0.13 dB. This superior performance extends across all compression levels (CRF18/23/28) and resolutions (720p, 1080p, 2K on Inter4K).
- Double Inference Speed: CDA-VSR achieves approximately 93 FPS on REDS4 (CRF=18), which is more than double the inference speed of TMP (45 FPS). At 2K resolution on Inter4K, CDA-VSR still maintains 25.1 FPS, significantly outperforming other methods which fall below the 24 FPS threshold.
- Efficiency Gains: MVGDA provides accurate alignment with reduced complexity. RMGF enhances detail reliability by suppressing misaligned regions. FTAR optimizes compute allocation, ensuring high quality for I-frames and speed for P-frames with minimal overhead.
Optimized for Enterprise Streaming
CDA-VSR’s design inherently addresses critical enterprise needs for online video applications such as conferencing, live streaming, and content delivery.
- Real-time Processing: The framework's high inference speed (93 FPS) ensures smooth, low-latency operation, making it ideal for real-time online VSR without compromising quality.
- Resource Efficiency: By intelligently leveraging compressed-domain information (motion vectors, residual maps, frame types), CDA-VSR avoids redundant computations and minimizes the need for complex, resource-intensive operations like optical flow estimation.
- Adaptive Performance: FTAR allows for dynamic resource allocation, ensuring that critical I-frames receive high-fidelity processing while common P-frames are handled efficiently, offering a balanced trade-off tailored to video stream characteristics.
- Robustness Across Conditions: Tested across various compression levels (CRF18/23/28) and resolutions (720p, 1080p, 2K), CDA-VSR consistently delivers top-tier performance, indicating its robustness in diverse operational environments.

Revolutionizing Online Video Streaming with CDA-VSR
The burgeoning demand for high-quality, real-time online video experiences (e.g., video conferencing, live streaming) faces significant technical hurdles. Traditional online VSR methods often fall short, struggling with complex motion estimation and redundant processing that lead to high computational burdens, especially at higher resolutions. CDA-VSR directly addresses these challenges by ingeniously integrating compressed-domain information – motion vectors, residual maps, and frame types – directly into its super-resolution pipeline. This allows for more efficient and accurate alignment (MVGDA), intelligent feature fusion (RMGF) that mitigates error propagation, and adaptive computational allocation (FTAR) across different frame types. The result is a system that not only significantly outperforms state-of-the-art methods in visual quality but also delivers more than double the inference speed, making high-fidelity online video streaming a tangible reality for enterprise applications.
