Video coding method and apparatus using multi-layer based weighted prediction |
摘要 |
A method and apparatus for efficiently encoding a plurality of layers using inter-layer information in a multi-layer based video codec are disclosed. The video encoding method includes operations of reading the weighting factors of one layer; performing motion compensation on reference frames for the current frame based on a motion vector; generating a predicted frame for the current frame by acquiring a weighted sum of the motion-compensated reference frames using the read weighting factors; and encoding the difference between the current frame and the predicted frame. |
