<p>The invention provides a decoding method of coded moving image signal and a decoding apparatus using the same, being a decoding method of moving image signal obtained by coding input digital moving image signals, gathering in a unit of one picture, issuing bit streams including the time information of present picture, accumulating the bit streams in the transmission side buffer, and decoding the bit streams being controlled to code a next picture when the buffer residue capacity becomes smaller than a certain threshold, characterized by calculating the time between pictures from the generated coding amount of the received previous picture, the threshold and transmission speed, comparing the time information extracted from the input bit stream and the time between pictures, and judging whether the extracted time information is correct or not. Accordingly, if there is an error in the time information of bit streams, the error can be detected, and decoding on the basis of wrong time information is prevented, so that obvious disturbance of decoded image can be prevented. <IMAGE></p> |
