On an information registering equipment, content of interest rendered by
media, such as a video image of interest distributed by TV broadcasting
is captured and displayed. Position/area on the image are defined with a
mouse or the like to obtain the target position/area. Information to
identify the content is obtained from the TV tuner. Reference information
is obtained through input means or by retrieval from the server for
reference information. The obtained information specifics are transmitted
to an information search equipment that in turn stores then into its
database. An information viewing equipment obtains the target
position/area and information to identify the content of interest and
transmits the thus obtained data to the information search equipment. The
information search equipment matches that data with each data record in
the database and transmits reference information to the information
viewing equipment on which the reference information is displayed.
