| Research Abstract |
We have developed a e-learning system that realizes high-resolution and low-bit-rate video distributions for chalk-and-talk based lectures. In this system, pictures of chalkboards taken by a high-resolution digital still camera and videos of a lecturer taken by a video camera are separately archived into web servers and distributed to students on the Internet, then superimposed on their computers. This method also realizes a low-bit-rate streaming.
