Abstract :
This paper provided a hybrid coding using spatial and spatial - temporal scalability terms, for coding video with high resolution. In the hybrid method, Intra and Inter video frames are encoded in two different ways. Intra frames are coded using SPIHT algorithm based on wavelet transform and Inter frames are coded using conventional MPEG-2 standard, based on DCT transform. With using this procedure, video is sent through two or three layers. The transmitted data from layers provided the video with different resolution and quality. There for, the user can choose the appropriate services based on their needs. In the spatial scalability, the base layer and enhanced layer have the same coding structure. But in the spatial - temporal scale when the second-upgraded-layer, because it contains only Inter frame, just coded based on standard methods. Simulation results of various videos with high resolution show the image quality of the proposed method in comparison of scalability in multiple layers in MPEG-2 standards.
