A broadcast video signal is captured on user command and processed to identify network addresses contain therein. Network addresses are stored together with information about the program during which they originated. Identified network addresses are accessed over the network to validate their correctness and a snapshot of the page displayed is stored and related to the network address. An HTML file is constructed showing the original image from which the HTML file was constructed, the address(es) extracted from the original image as hypertext lines and snapshots of the corresponding images. By viewing the HTML file, a user can quickly determine if he wishes to retrieve information from the network addresses and can do so by clicking in the hypertext links.
