<p>The video bookmark feature allows a user to tag an item or segment of interest within audio/video content being watched. Each tag, or bookmark, can contain within it metadata associated with the content captured by the receiver at the time the bookmark was recorded; further information can be derived via interaction over the Internet with a service provider. Applications supported by video bookmarks include telescoping ads, capturing screen shots for later review or printing, and retrieving more information about any arbitrary subject being viewed, whether it is a scene in a program, an advertisement, or other associated information about the subject. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.</p> |
