ABSTRACT:
A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a previously-transmitted image that has been stored at a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the quality of the image at the remote location improves over time. The difference information may be encoded in a format compatible with existing video compression standards and processed by a receiving terminal regardless of the presence of still mode capability.
