Effective Broadband Video Streaming during wireless vertical handovers

While video streaming, vertical handover between heterogeneous wireless networks remains a scarcely addressed problem. Broadband Video Streaming (BVS) with adaptive packet retransmission promises better video quality during a Hard Handover (HHO) than both raw UDP transport and traditional congestion-controlled streaming, making it attractive to mobile video streaming services. It achieves this by distinguishing between high congestion and poor channel conditions, the latter of which an HHO induces, and by prioritized retransmission according to picture type.
