ABSTRACT:
A motion vector detected by a motion detector (2) and a quantizing parameter and a frame structure determined by a controller (4) are stored in a memory (5). The data thus stored is supplied to an encoder (3) which carries out the encode processing corresponding to the stored data. Thus, the data are coded via multiple paths which can reduce restrictions from the standpoint of time and also reduce the scale of hardware need for encoding.
