ABSTRACT:
In a transmitter, a motion detector detects a motion amount of a coded block. A buffer memorizes a detected motion amount. A buffer controller controls the buffer to read the motion amounts in the order opposed to the writing order. A switch selects one of outputs. In a receiver, a sync word detector discriminates first and second sync words. A primary frame memory memorizes an actually decoded image. A secondary frame memory memorizes a predicted image corresponding to the actually decoded image. Memory controllers read out the image information of coding blocks from the corresponding frame memories in an order opposed to the writing order. A switch selects either one of the information of the primary or secondary frame memories.
