Paper Abstract

In several papers, the basic concept of a 64 kbit/s video-codec was presented with different points of emphasis. Based on the system presented in [1], several methods are investigated to enhance the reconstructed picture quality of this codec. The basic coding concept consists of a reduction of the temporal and the spatial resolution, a block oriented motion compensated DPCM, and a DCT-coding. The investigations include time-filtering, dual spatial resolution, an improved motion estimation, and a modified coder and buffer control.
