<p>A transaction controller is provided either in a digital television receiver or a set top playback device for detecting product identification records embedded in a video data stream. The product identification record is inserted into a recorded or broadcast video program data stream. A user may utilize a remote control to input preferences, billing and shipping information and any other information necessary for completing an order. The transaction controller identifies the product identification record and attaches a generated product order record along with a stored user identification record. The combination of records are then encoded and sent to the product supplier for fulfillment.</p> |
