(57) Abstract The presumption time stamp in the video transmission device, the MPEG-2 program encoder, the multiplexer and the splicer Outside 53 Manner and the device in order to calculate are disclosed. Actual time Y of data packet number t _t, it possesses the next linear form. Several 48 Here Outside 54 It is the disturbance component of the small tonnage for the linear relation between time and packet number. Actual time of data packet number t, Several 49 It is observed as. However, Outside 55 It is observational error. As for the time stamp which is presumed, Several 50 With, and Outside 56 Value Outside 57 Several 51 With in order to make depends on the excess, it generates. The value which can as a result becomes accurate and smooth presumption time stamp.
