ABSTRACT:
The invention enables a user to obtain a document associated with the program content of a video signal. Coded data on a surface is read by a sensing device which generates indicating data which is a request for the document. A computer system receives the indicating data from the sensing device and extracts document identity data from the video signal, in order to retrieve the document.
