Abstract
A broadcast station 10 transmits a broadcast signal having content data and origin data both multiplexed thereto. An information access system 20 receives the broadcast signal, and extracts the content data and origin data. The content data includes for example a HTML file or a icon data. The information access system displays the content data and access to a WWW server 30 located on the internet using the display of the content data on the screen. While accessing the server, the information access server transfers the origin data to the server. The server stores the origin data and uses it immediately or later. The server discriminates the access using the content data multiplexed to the broadcast signal, from other types of access, using the origin data stored therein.
