A System Level Framework for Streaming 3–D Meshes over Packet Networks
In this paper, a system-level framework is proposed for 3-D graphics streaming. The proposed architecture is scalable with respect to the variations in both bandwidth and channel error characteristics. We consider the end-to-end system, and jointly optimize pre-processing and post-processing solutions. In particular, forward error correction (FEC) and multiple description (MD) codes are applied to the base-layer mesh; FEC codes are applied to enhancement layer connectivity data; and unequal error protection (UEP) and error-concealment methods are applied to the geometry data. Re-transmission is utilized wherever it is applicable as determined by the delay requirements. Furthermore, the performance analysis of the system is also provided.
