Abstract
A broadcast pause and resume system may enable replay from a random access memory of video information received from a video distribution source such as cable, broadcast television or satellite distribution as examples. Key frames may be stored which enable the replay from the memory of both video and enhanced content. In some embodiments of the present invention, a reference to stored enhanced content may be stored instead of storing the entire contents of a browser cache.
