Interframe Coding of 525-Line, Monochrome Television at 1.5 Mbits/s

Abstract

Interframe coder simulation results are described for standard-broadcast-rate monochrome television in applications where the television camera is largely stationary, such as TV-conferencing or video telephone. An algorithm for coding at 1.5 Mbits/s, whose parameters were optimized via trial and error, produces pictures with little resolution loss for low-to-moderate movement, but somewhat visible moving-area resolution loss for higher movements.
