摘要：This paper proposes an ultrafast scalable embedded image compression scheme based on discrete cosine transform. It is designed for general network architecture that guarantees maximum end-to-end delay (EED), in particular the Distributed Multimedia Plays (DMP) architecture. DMP is designed to enable people to perform delay-sensitive real-time collaboration from remote places via their own collaboration space (CS). It requires much lower EED to achieve good synchronization than that in existing teleconference systems. A DMP node can drop packets from networked CSs intelligently to guarantee its local delay and degrade visual quality gracefully. The transmitter classifies visual information in an input image into priority ranks. Included in the bitstream as side information, the ranks enable intelligent packet dropping. The receiver reconstructs the image from the remaining packets. Four priority ranks for dropping are provided. Our promising results reveal that, with the proposed compression technique, maximum EED can be guaranteed with graceful degradation of image quality. The given parallel designs for its hardware implementation in FPGA shows its technical feasibility as a module in the DMP architecture.
