US 2015/0319443 A1 · HIGH SPEED SCALABLE VIDEO CODING DEVICE AND METHOD USING MULTI-TRACK VIDEO

Abstract

The present invention relates to a high speed scalable video coding device and method using a multi-track video, and the scalable video encoding device comprises: a video array unit for arraying a multi-track video in a plurality of layers according to a set standard; a bit stream analyzing unit for analyzing each layer of a bit stream and extracting encoding information including an encoding mode and prediction information; a layer for carrying out scalable video encoding; and a scalable video coding (SVC) encoding unit for determining the encoding mode using the encoding information of an upper or a lower layer of a layer carrying out the scalable video encoding, and for encoding in the determined encoding mode. The scalable video encoding device and method of the present invention enhance the speed of encoding a multi-track video into a scalable video by using the encoding information of a standard multi-track video.
