Figure 1 illustrates the high‑level pipeline. The encoder receives raw YUV 4:2:0 frames, processes them through a multi‑scale feature extractor (MFE), then quantizes the latent representation with a learned context‑adaptive entropy model (C‑EAM). The resulting bitstream is packaged into MP4 mdat and custom snis boxes that delineate base and enhancement layers. The decoder mirrors the pipeline, progressively reconstructing the frame as more layers become available. | Item | What to Verify | |------|----------------|
