Abstract
A television system allows a viewer of a text-enhanced television program to pause the program at a particular frame, browse the enhancements at his or her leisure, and then resume viewing the program from that frame, without losing continuity of the video and enhancement portions of the program, or program content. This is accomplished by time-shifting the television program for later playback. Time-shifting is accomplished through the use of mass storage devices such as semiconductor memory, optical disks, magnetic storage and other FIFO data storage structures. Markers are available that allow the viewer to return to the program at the point that he stopped watching, replaying the program from that point. Text enhancements are provided through the VBI present in a conventional television broadcast signal, through an Internet connection, or by a wireless means such as a pager or cordless telephone. Additionally a back link may be utilized to allow the viewer to summon the text enhancements or interact with the enhancements already present.
