<P>PROBLEM TO BE SOLVED: To allow a terminal to detect watermark data from a broadcast signal, thereby displaying information relating to the watermark data, on the terminal; and to measure the contact with such information by the terminal. <P>SOLUTION: A terminal acquires a voice from a receiver (TV)(S105). A server obtains a program or CM title and a URL with respect to watermark data included in inquiry data from the terminal, and makes a response to the terminal (S107). The terminal connects with the URL automatically or with user's permission (S109). A web site designated by the URL transmits a corresponding web page (S111). The terminal receives web page information from the web site and displays the information on a display (S113). A measurement server logs a contact log by the terminal (S115). <P>COPYRIGHT: (C)2013,JPO&INPIT |
