Abstract
A frame memory is provided which has five fields each having N slots, and three additional slots. Each slot has a storage capacity to store eight image lines. Four fields of the five fields serve to store motion compensation reference frames. The remaining one field and the three additional slots are used for B-picture interlace conversion. Disposed in a control unit are a slot control memory, a write slot pointer, and a read slot pointer. For an image output unit to acquire information from the frame memory in a correct slot order, the contents of the slot control memory are updated at the time of performing write operation to enter information into the frame memory by a bit stream analysis unit.
