Abstract
A resident application and a second application are provided in a set-top terminal to receive a TV broadcast service and network personal video recorder (NPVR) service, respectively. The resident application is suspended in favor of the second application when a user changes from a broadcast channel to an NPVR enabled channel, and vice versa. In an embodiment where a digital video recorder (DVR) set-top terminal is used, a DVR server therein provides trick mode functions (pause, rewind and fast-forward) before an NPVR session, e.g., a Look Back session, is established. In another embodiment, during an NPVR session the DVR server plays back recorded programming content downloaded from a communications network, and provides trick mode functions as well.
