ABSTRACT:
An input video signal is encoded at a plurality of coding layers exhibiting different spatial resolutions. The input video signal is spatially scaled down to a resolution-lowered video signal that exhibits a resolution lower than the video signal. The resolution-lowered video signal is encoded by using a quantization parameter, with a decoding procedure, thus obtaining first coded data and a decoded signal. The decoded signal is spatially scaled up through a high-resolution procedure for controlling high-frequency components estimation depending on the quantization parameter, thus obtaining a high-resolution scaled-up video signal. The input video signal is encoded through inter-spatial resolution prediction using the high-resolution scaled-up video signal as a predictive signal, thus obtaining second coded data that exhibits a resolution higher than the resolution-lowered video signal.
