Abstract
An interactive television system has a set-top box adapted for use with a television and a remote control handset. The set-top box is connected to receive a television broadcast that is filmed using multiple cameras situated at various camera viewpoints. The television broadcast has a primary channel, with which the viewer is familiar as carrying the desired television program, and multiple virtual channels associated with the primary channel. The virtual channels carry video signals from the multiple different cameras covering the event. The remote control handset has dedicated camera control buttons for selecting corresponding virtual channels to allow the viewer to choose a desired camera viewpoint. The dedicated camera control buttons are arranged in an intuitive pattern that correlates to the camera viewpoints.
