Abstract: Internet Television video-streaming schemes do not respond well when access is through a broadband wireless link. A simple but effective negative acknowledgment-based scheme has been designed to meet the needs of Internet Television, one form of Internet Protocol Television (IPTV). When used with broadband Worldwide Interoperability for Microwave Access (WiMAX), simulations show that the scheme has the better features of both raw User Datagram Protocol (UDP) transport and the standardized Datagram Congestion Control Protocol (DCCP) but does not have those protocols disadvantages. The delivered video quality is also found to be superior to multiple-connection DCCP. One way that Internet Television will spread even more rapidly is if it is available to wireless devices as well as through existing conventional wired access. This is more likely to occur if an appropriate wireless video-streaming scheme is used, as video quality is a key determinant of customer choice
