as providing a solution which will enable the encoding of a video
signal which considers the coding history of the video signal
when the actual coding parameters are not available.
Representative claim 1 is reproduced as follows:
1. A method for second or later generation coding of a
video signal in tandem stage coding which includes a previous
stage coding process and a later stage coding process which are
separately and sequentially executed, comprising the steps of:
estimating at least one coding parameter used in the
previous stage coding process in accordance with picture
properties of the video signal coded by said previous stage
coding process; and
secondly coding the video signal coded by said previous
stage coding process, based upon the estimated coding parameter.
