<p>A purchase code, such as a web address indicating a webpage of a product at a merchant's website, may be embedded into a video advertisement by steganography. The video advertisement embedding the purchase code may be displayed to consumers on televisions or on display kiosks installed at a merchant's storefront. A consumer, who is viewing the video advertisement and is interested in purchasing the product being advertised, may point a mobile device with a camera, e.g., a smart phone, to scan the video advertisement with the camera. The mobile device may decode the video advertisement to capture the purchase code embedded in the video advertisement. The purchase code may automatically direct the mobile device to visit the product web page at the merchant's web site. Thus, the consumer may purchase the product immediately at the merchant's web site.</p> |
