System architecture for synthetic/natural hybrid coding and some experiments

This paper presents a system architecture for synthetic/natural hybrid coding toward future visual services. Scene-description capability, terminal architecture, and network architecture are discussed by taking account of the standardization activities: MPEG, VRML, ITU-T, and IETF. A consistent strategy to integrate scene-description capability and streaming technologies is demonstrated. Experimental results are also shown, in which synthetic/natural integration is successfully carried out.
