Summary
- What is new: Introduces ViSOR, a video super-resolution-based encoding scheme that optimizes for low latency and energy efficiency in online streaming.
- Why this is important: Existing per-title encoding schemes don’t adequately balance encoding time, energy efficiency, and perceptual quality in streaming applications.
- What the research proposes: ViSOR uses random forest models to predict perceptual quality and encoding time for various resolutions, adjusting to maintain quality while reducing bitrate and energy consumption.
- Results: Achieves a bitrate reduction of 24.65% and 32.70% for PSNR and VMAF quality metrics, respectively, and cuts storage consumption and encoding energy by 79.32% and 68.21%, promoting greener streaming.
