Disparity Codec Architecture for 3D Teleconferencing Systems

International Journal of Electronics, Vol. 89, No. 5, 2002, pp. 347-363.

Abstract: This paper presents the architecture and the design methodology of an advanced and flexible codec optimized for disparity information compression and transmission over ATM Constant Bit Rate channels. For this development we used a three-stage procedure, which benefits from the utilization of formal design methods and the reuse of its functional blocks for a more efficient and flexible implementation at the encoder and the decoder side. The codec design provides the basis for defining and testing improved functionality that increases the performance of teleconferencing systems, while allowing a migration path to other hardware implementations depending on which functionality needs to be optimized.
