We have held several experiments on distribution of some events with satellite communications, the Internet and ISDN. From the experience of these experiments on distribution, we have been studying about distance learning. We considered a video overlay technique of a lecturer image and presentation materials image, in case of a lecturer explains presentation materials. We thought that the lecturer image should be putted into the presentation image to avoid decreasing of the concentration to the lecture of the students. To practice the overlay of these two images, the lecturer have to operate the hardware of a video effector or the another staff must be required for operation. So we propose a system to automatically overlap these two images with a personal computer and two video capture cards. The region into where the lecture image will be putted is decided by three kinds of method. The methods will be described and the results of image overlaying by the methods will be compared.
