Video streaming over wireless networks has lately gathered immence interest especially among smart phone users. While video streaming, vertical handovers in heterogeneous wireless communication networks remains a scarcely addressed problem. Broadband Video Streaming (BVS) scheme, with an adaptive packet retransmission attribute, promises better video quality during a Hard Handover (HHO), as compared to both the raw UDP transport as well as the traditional congestion-controlled streaming, making it on attractive proposition suiting mobile IPTV services. The Adaptive BVS enures improved video content delivery through prioritized retransmissions based on the picture type, and by distinguishing between high congestion and poor channel conditions, the latter induced by an HHO. Here, we evaluate the performance of Adaptive BVS scheme in a dual-handover scenario to validate it as an optimal solution for effective mobile IPTV video streaming.
