ABSTRACT:
In one embodiment, the present invention is a t-commerce platform, which is linked to the content from a video signal that the user is currently watching. At some point during the broadcast of the content, a close-up of the product is shown. Simultaneous with this, a VBI-based trigger is added to the video signal of the broadcast. This trigger causes the television, a set-top box, or a similar device to capture in a memory, a “freeze-frame” of the image being shown. This action is transparent to the user while the video being displayed on the television is continuing normally. If the user chooses to perform an interactive “buy” transaction the saved image data is used as part of the interactive screen display.
