Abstract
A method and apparatus detects a presence of a change in encryption status of video information, such as a preview, in a video stream. The method and apparatus issues notification information such as through a visual user interface, audibly or in any other suitable manner, that new content, such as a pay per view video information, is either available or unavailable based on the detection of a change in encryption status of the video information. An interactive and automated technique is provided to inform a user while, for example, the user is watching a display device, that a preview of content is now available or that a previously available preview has now changed and is now encrypted and therefore a user must order the previewed content before an expiration period occurs. In this fashion, a user is automatically notified that a free preview is available, while watching television and a broadcaster may increase revenues since preview information is more readily detected and presented to potential customers.
