Abstract
In a staggercasting system, a receiver estimates a delivery time of a packet from a main stream and, if the packet from the main stream is not received at the estimated delivery time, the receiver substitutes a corresponding packet from the stagger stream. As a result, a loss can be detected quicker since the receiver does not have to wait until detection of a missing sequence number and, therefore, the receiver can accommodate the time of presentation such that the user does not suffer a loss in quality of service.
