ABSTRACT:
A viewing surveillance system which make it possible to carry out the viewing surveillance independently from the broadcasting form like analog broadcasting or digital broadcasting. The viewing surveillance system also make it possible to carry out the viewing surveillance without any restriction set to viewers or any burden to the broadcast stations. The image feature data generating unit12receives a picture signal from the image viewing terminal50, and generates the image feature data which represents a feature of the image from the picture signal. The image information transmitting unit13transmits the image feature data generated by the image feature data generating unit12to the viewing surveillance server2. On the other hand, the image feature data generating units21ato21calso generates the image feature data based on the broadcasted programs and stores the image feature data in the program image feature data storing unit22. The viewing program specifying unit23specifies the viewed program by matching the image feature data received from the image information transmitting unit13and the image feature data stored in the program image feature data storing unit22.
