Paper Abstract

A 64 KBPS codec for digital transmission of full motion monochrome video, which makes allowances for synchronization (frame, field and line) is proposed. Various combinations of down-up conversions, temporal filters, motion compensated frame interpolation, transform/predictive coding, quantizer and geometrical zonal sampling are applied to video sequences with an objective to obtain optimum combination. Simulation results based on these techniques are reported. A viable scheme for teleconferencing at 64 KBPS is proposed.
