Abstract
System and method for switching a stream to a new transmission medium. A first stream may be received. A first plurality of packets of the first stream may be transmitted to a second device on a first transmission medium. The first plurality of packets may include one or more index marker packets. It may be determined that at least a portion of the first plurality of packets may not have been received by the second device. A second plurality of packets of the first stream may be transmitted to the second device on a second transmission medium. The second plurality of packets may include at least a subset of the first plurality of packets and at least a subset of the one or more index marker packets. The one or more index marker packets may be configured for use by the second device to detect and discard duplicate packets.
