Abstract
Multiple associated video channels are recorded by a digital video recorder so that during playback a user can select among the channels while channel playback synchronization is maintained. A cable television set-top box application allows a primary channel to have secondary channels associated with the primary channel. The secondary channels include substantially the same program content as the primary channel but also include additional information such as tags having text descriptions of objects shown in the program's video. By selecting either the primary or a secondary channel a viewer has the appearance of the tags being turned on or off while the continuity of the program presentation is maintained.
