Abstract
This paper presents an HD (High Definition) streaming system that employs an AL-FEC (Application-Layer FEC) scheme (i.e., DVB AL-FEC) based on Raptor codes to protect the transmission of MPEG-2 TS (Transport Streaming) over RTP streaming packets over error-prone Wi-Fi multicast channels. The employed AL-FEC scheme can effectively recover the missing Wi-Fi multicast packets in a scalable way. In this paper, we describe the prototype of the proposed HD streaming system, which is implemented based on VLC server and VLC client over Linux operating systems. Finally, we show that the proposed system can significantly improve the HD video quality of a Wi-Fi multicast streaming service. © 2013 IEEE.
