Abstract
This paper introduces an adaptive temporal scalable decoding scheme with temporal and spatial prediction method. This method can be used to reduce the decoding time and reduce the decoding power consumption by skipping the decoding process of some frames and reducing the frame rate. With the spatial prediction and the temporal prediction, it is different from the certain frame skipping scheme in the temporal scalable decoding process with frame rate down conversion method (TSDP) [2]. This method chooses the skipping scheme which causes minimum cost by considering the video quality loss when the current frame is skipped and the movements of the current frame, so this method can be also used in the common video cases well. It is compared with the process which only used the temporal prediction method [3], the video quality (PSNR) is improved about 0.94.6 dB in the experimental common video cases by using the combined method. It can reduce the decoding time based on the number of the skipped frames, and can also get about 65%-86% reduction which compares with the frame rate reduction in the experimental cases.
