In accordance with one aspect of the invention, a method of receiving content over a content delivery system is provided. The method includes receiving a user request to initiate a rewind operation on content locally available in a live-off-disk (LOD) buffer. The content is associated with an event received over a content delivery system. If all of the event is not available in the LOD buffer, a message is communicated over the content delivery system to a headend requesting remaining content associated with an unreceived portion of the event. In response to the message, the remaining content is received from the headend over the content delivery system.

Simultaneous display of multiple audio/video (AV) programs transmitted over a digital link is described. At a source device, at least one non-composited digital transport stream is generated from the plurality of AV programs. The at least one non-composited digital transport stream is augmented with control information. The control information is operative to invoke simultaneous display of the plurality of AV programs on a display device. The at least one non-composited digital transport stream is then transmitted as augmented over the digital link. At a sink device, at least one non-composited digital transport stream having the plurality of AV programs is received over the digital link. Control information is extracted from the at least one non-composited digital transport stream. The plurality of AV programs are identified within said non-composited digital transport stream in response to the control information. The identified AV programs are then simultaneously displayed on the display device.
