Delivering high definition video (HDV) is a typical application on the next generation Internet (NGI). This paper pays attention to the packet loss during real-time delivering of HDV, aiming to seek an effective FEC scheme, which causes negligible additional delay and can meet different users' requirement of quality of service (QoS). Based on the character analysis of HDV, we propose a new FEC scheme based on Tornado Codes, with some special design to reduce the extra calculation load and provide QoS choice to users. Many experiments are conducted to evaluate the performance of our scheme. Experimental results show that, our scheme can effectively protect real-time HDV data, and users can custom the QoS level in a reasonable range.
