Ultrafast Scalable Embedded DCT Image Coding for Tele-immersive Delay-Sensitive Collaboration
International Journal of Advanced Computer Science and Applications(IJACSA) (2013)

A delay-sensitive, real-time, tele-immersive collaboration for the future requires much lower end-to-end delay (EED) for good synchronization than that for existing teleconference systems. Hence, the maximum EED must be guaranteed, and the visual-quality degradation must be graceful. Distributed Multimedia Plays (DMP) architecture addresses the envisioned collaboration and the challenges. We propose a DCT-based, embedded, ultrafast, quality scalable image-compression scheme for the collaboration on the DMP architecture. A parallel FPGA implementation is also designed to show the technical feasibility.
