Abstract:
1. A scalable video encoding device, comprising: a video array unit for arraying a multi-track video in a plurality of layers according to a set reference; a bit stream analysis unit for extracting encoding information, comprising an encoding mode and prediction information, by analyzing a bit stream of each of the layers; and an SVC encoding unit for determining an encoding mode using encoding information about a layer on which scalable video encoding is performed and an upper or lower layer of the layer on which scalable video encoding is performed and performing encoding in the determined encoding mode, wherein the video array unit arrays the multi-track video in the plurality of layers such that a video having higher resolution is disposed in a higher level, arrays the multi-track video in the plurality of layers such that a video having a higher frame rate is disposed in a higher level if two or more videos having identical resolution are present, and arrays the multi-track video in the plurality of layers such that a video having a higher bit rate is disposed in a higher level if two or more videos having identical resolution and frame rate are present.
