Document Type and Number:
Japanese Patent JP4362702
Kind Code:
B2
Abstract:
A broadcasting station server distributes a video program and calculates a viewing time of each viewer who is viewing the video program. When the video program is finished, the broadcasting station server sends the user ID of the viewer who has viewed the video program and the viewing time thereof as viewing information through the Internet to a data center. The data center selects the user ID of a viewer whose viewing time of the video program is longer than a predetermined time from the received viewing information, and distributes advertisement information corresponding to the video program, together with a reception acknowledgment added thereto, to a mail address corresponding to the selected user ID. If the reception acknowledgment is not returned from the recipient of the advertisement information, the data center keeps on sending the advertisement information at predetermined time intervals until the reception acknowledgment is returned.
