COMPRESSED REFRESH BUFFER ABSTRACT Data compression is effected in the refresh loop of a transient video display. The digital image is divided into equal areas and mapped in a bit map store. If an area contains one bits it is represented by a one in the bit map store, otherwise it is represented by a zero. A refresh buffer store contains only those areas including one bits. The buffer and bit map stores are operated synchronously and zeroes are forced in the data stream to the video display when zero is detected in the bit map store. Extension of the scheme to provide for colour displays is described.
