Scalable video coding method and apparatus using base-layer |
摘要 |
A method of more efficiently conducting temporal filtering in a scalable video codec by use of a base-layer is provided. The method of efficiently compressing frames at higher layers by use of a base-layer in a multilayer-based video coding method includes (a) generating a base-layer frame from an input original video sequence, having the same temporal position as a first higher layer frame, (b) upsampling the base-layer frame to have the resolution of a higher layer frame, and (c) removing redundancy of the first higher layer frame on a block basis by referencing a second higher layer frame having a different temporal position from the first higher layer frame and the upsampled base-layer frame.
