ABSTRACT:
In a multi-location television conference system that connects five locations A, B, C, D, and E, when speeches take place at the four locations A, B, C, and D at the same time, at a listening location E, images of all the speaking locations A, B, C, and D are displayed on one screen with four divided screen areas. On the other hand, at the speaking location A, images of the speaking locations B, c, and D and an image of the former speaking location E are displayed on one screen with four divided screen areas. In addition, when images of speaking locations are displayed, locations names thereof are also displayed. Thus, a television conference held at a plurality of locations at a time can be smoothly managed as with a real conventional conference.
