VIDEO CODING AND DECODING METHODS USING INTERLAYER FILTERINGAND VIDEO ENCODER AND DECODER USING THE SAME

摘要

Video coding and decoding methods using interlayer filtering and a video encoder and decoder using the same are provided. Multi-layer video coding employing a plurality of video coding algorithms can improve video coding efficiency by using interlayer filtering. The video coding method includes encoding video frames using a first video coding scheme (410), performing interlayer filtering on the frames encoded by the first video coding scheme (440), encoding the video frames using a second video coding scheme by referring to the frames subjected to the interlayer filtering (420), and generating a bitstream containing the frames encoded by the first and second video coding schemes (430).
