Implementation of 3D-DCT based video encoder/decoder system

Abstract

3D-DCT technique is used in video system to eliminate the need for motion vectors computations in the encoder or motion compensation computations in the decoder. This paper focuses on the hardware implementation of the video encoder/decoder system design. A complete design of the quantizer and VLC in the encoder side, as well as design of dequantizer and VLD in the decoder side is implemented to complete the system. Finally the system is targeted on one of the well-known Field Programmable Gate Arrays (FPGAs) provided by ALTERA Corp. and simulated using sample inputs.
