Abstract :
The essential components of future e-learning systems will include real-time video capture, video transmission, and video display; a high-definition image display at the receiver in the real-time teaching depends on the promise of a high-resolution video and a greater compression. This paper designed a high-performance terminal for the real-time video capture in e-learning systems; it is a terminal not only built on FPGA module and DSP parallel working system but also enhanced by improved MPEG-4 algorithm. The experiment results of this terminal demonstrated a significant effectiveness of compressing a high-resolution real-time video.
