TWO-WAY VIDEO IMAGE COMMUNICATION METHOD AND ITS EXECUTION SYSTEM

摘要

PURPOSE:To easily call a program by storing retrieval data for a video program designated by a callee for each callee, allowing a sender side to acquire the stored retrieval automatically and sending the video program to the callee. CONSTITUTION:A callee retrieves a video program by selecting a menu or the like displayed on a screen of a display device 107. Lots of video programs are served and since all programs are not easily understood if they are displayed in a list form, the programs are classified into categories such as movies and sport. Suppose that a callee desires to watch programs A-1-2 and C-1-1 and registers the programs, then data representing a program 1 to be A-1-2 and a program 2 to be C-1-1 by each callee are stored in an information storage device 109. When the callee designates the program 1, the sender acquires the retrieval data from the device 109 automatically and designates the program without troublesome retrieval.
