Abstract

PURPOSE:To rapidly cope with the movement of a video by adding a counting means and a processing mode decision means to a picture transmitter and controlling an encoding mode according to input digital data. CONSTITUTION:An encoding processing time is counted by the counter 50 connected to a highly efficient encoding part 30 and accumulated at every constant time. This value is applied to one of the comparator of the processing mode decision circuit 60. When the output of a difference from a reference value is inputted to a ROM 62 and the quantity of encoded generation information exceeds the reference value, a control signal for having the encoding mode of the large number of steps to the highly efficient encoding part 30 from the ROM 62. Consequently, an overflow or and underflow can be eliminated to reduce the delay of a control.
