Frame compression method to use the base layer, the video coding method, frame restoration method, video decoding method, video encoder, video decoder, and recording medium

摘要

A relates to video compression, the present invention relates to a method of using the base layer in scalable video coding, performs a temporal filtering more efficiently and more. Performs spatial downsampling and temporal downsampling for the original video sequence is input, the minimum frame rate is supported and temporal filtering method in a scalable video encoder according to the present invention, produces a video sequence having the lowest resolution A method to, after encoding at a predetermined codec the base layer, a step of decoding, comprising: up-sampling at the highest resolutions supporting base layer is decoded, the temporal level the top of the original video sequence and a stage of filtering by using the base layer is up-sampled to the present frame.
