Abstract
A system and method are provided for displaying an active uniform network resource locator during playback of a media file or media broadcast. In one embodiment, a uniform network resource locator can be embedded in a media file. In another embodiment, a video signal or media broadcast can contain information encoded contemporaneously with or prior to broadcast defining an embedded uniform network resource locator. An output for display is generated based upon the media file or media broadcast where display of the output shows the embedded uniform network resource locator as active during display of the output. The user is then allowed to activate the embedded uniform network resource locator. In response to activation by the user, the embedded uniform network resource locator can be followed to retrieve a resource addressed by the embedded uniform network resource locator.
