SYSTEM AND APPARATUS FOR LOW-COMPLEXITY FINE GRANULARITY SCALABLE VIDEO CODING WITH MOTION COMPENSATION |
摘要 |
<p>A coding structure is configured to improve coding efficiency together with reduced encoding and decoding complexity for scalable video encoding. Especially, the case of coding multiple FGS layers on top of a discrete layer is considered. For coding multiple FGS layers, a decoder-oriented two-loop structure is used. At the decoder side, the new structure has similar complexity as the two-loop structure while providing similar coding performance as multi-loop structure. The coding structure and method is configured for preventing the drift effect in case of partial decoding due to the usage of FGS layer for inter-discrete-layer prediction, and aims at effectively utilizing temporal prediction in FGS layer coding to improve coding efficiency. The coding method can avoid additional transform operations; avoid applying in-loop de-blocking filter to FGS layers; and use simpler residual transform on FGS layers.</p> |
