for H.264 HD Video Over WLANs

Abstract


size=3>High Definition video streaming over WLANs faces many challenges


because video data requires not only data integrity but also frames


have strict playout deadline. Traditional streaming methods that rely


solely on either UDP or TCP have difficulties meeting both requirements


because UDP incurs packet loss while TCP incurs delay. This


presentation presents a new streaming method called Flexible
Dual-

TCP/UDP Streaming Protocol (FDSP) that utilizes the benefit of both


UDP and TCP. The FDSP takes advantage of the hierarchical structure


of the H.264/AVC syntax and uses TCP to transmit important syntax


elements of H.264/AVC video and UDP to transmit less important


elements. The proposed FDSP is implemented and validated under


different wireless network conditions. Both visual quality and delay


results are compared against pure-UDP and pure-TCP streaming


methods. Our results show that FDSP effectively achieves a balance


between delay and visual quality, thus it has advantage over traditional


pure-UDP and pure-TCP methods.
