Abstract

The idea relates to still image video transmis- sion. A Sum of Absolute Difference (SAD) calcula- tion is used to determine the time at which a dis- played image has reached a sufficient quality such that no further progressive refinement bits need be transmitted. This both optimizes the quality in an automated way for the viewer, and reduces the bandwidth demands on the transmission system.
