PROBLEM TO BE SOLVED: To realize an interactive image distribution service utilizing one-way communication equipment. SOLUTION: A distribution server 1 encodes images photographed with a camera 7-1 by a program sponsor, in real time and distributes them to a viewer terminal 3-1 by multicasting. The viewer terminal 3-1 receives and decodes images distributed from the server by multicasting and displays the images. A management server 5 recognizes a program reception condition of the viewer terminal 3-1 and controls real-time encoding of images performed by the viewer terminal 3-1, the images being photographed with a camera 7-2 connected to the viewer terminal 3-1, and controls start/stop of multicast distribution of the images. A monitor terminal 4 gives opportunities for starting and stopping multicast distribution from viewers to the management server and receives and decodes images distributed from the viewer terminal 3-1 by multicasting to display the images.
