Abstract

A digital video recording system receives a first stream of on-demand video content and can both record the video content and route the video content for viewing on a display device. In response to a viewer request to fast-advance the video content display, the digital video recording system can request a second stream of the on-demand video content and route the second video content for fast-advance display on the display device while continuing to record the first video content without interruption and without a change in the speed at which the video content is recorded.
