SCALABLE VIDEO DECODER AND CONTROLLING METHOD FOR THE SAME |
摘要 |
PURPOSE: A scalable video decoder utilizing a property of single loop decoding mode and controlling method thereof are provided to run an image enlargement calculation with macro block information and a neighboring task part of the lower layer, after an encoding of a lower layer, if texture or residual is needed in a higher layer encoding so reducing a necessary memory usage. CONSTITUTION: A macro block mode decision unit(110) determines the macro block mode of the higher layer when decrypting the scalable image. When the macroblock mode of the higher layer is an inter-layer reference mode. An enlargement operation unit(120) magnifies the texture by using the correspondence macro block data and a neighboring pixel information of the lower layer. Or the enlargement operation unit enlarges the residual by using a macro block information of a lower layer. A decoder unit(130) decodes the higher layer by using the texture or the residual enlargement. |
