<p>A method and device are disclosed for calculating estimated time stamps ìt in video distribution apparatus, MPEG-2 program encoders, multiplexers, splicers. True times Yt of a data packet number t having the linear form: Yt = Yt-1 + Jt, Jt = Jt-1 + tt, with tt being a small perturbation relative to the linear relation between time and packet number. The true times of data packet number t are observed as: ot = Yt + ht, where ht is an observational error. The estimated time stamps are produced according to: ìt = ìt-1 + βt and such that the value of βt is made dependent on the exceeding by #ot - ìt-1 - βt-1 # of max[ht]. The results are accurate and smooth estimated time stamps.</p> |
