ABSTRACT:
A multimedia display system for efficiently and economically displaying document information containing characters, a graph and a picture image, without using a large-capacity image memory is disclosed in which information in a window is directly written in a bit-map memory or the display screen of a display device, without necessitating an image memory having a storage capacity corresponding to one page of a document. The multimedia display system is effectively used in the multiwindow display method, and includes a transfer controller for controlling data transfer between the bit-map memory and a memory device including a main memory, a picture image memory and a font memory, to control the size, position and contents of each window and to make possible image synthesis or image conversion.
