Decoding method for reducing delay time

摘要

A decoding method for reducing a delay time which makes a decoder perform continuously by controlling a relief width according to the characteristic of an input image is provided. The decoding method includes the steps of: (a) sequentially storing an input image signal in a buffer which predetermines a relief width; (b) performing decoding if the amount of the stored image signal is larger than the predetermined relief width of the buffer; and (c) resetting the relief width of the buffer by combining the prescribed decoded information. The relief width of the decoding input buffer is controlled according to the characteristics of the input image to make the decoder perform continuously and reduce a delay time, so that it has an effect of cleaning up the discomfort which a user may feel in watching an image signal.
