Abstract :
A 3D-DCT technique is used in video systems to eliminate the need for motion vector 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 the design of the dequantizer and VLD in the decoder side are 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.
