Abstract:
IPTV is one of the developing technologies in recent years. This technology is used to broadcast TV programs over IP protocol stack. Video quality improvement is the most important advantage of this technology. Users can watch programs anytime they want in opposition to the traditional TV channels in which programs cast at certain times. One of the challenges in IPTV is high latency for channel switching. This latency is caused by different sources, including network delay. The delay between sending the channel switch request and receiving the first packet of the new channel is called network delay. In this thesis a new approach is proposed to decrease network delay. The proposed approach benefits from software defined networking architecture. Experimental results show 18 to 23 milliseconds for network delay, which is 50 to 80 percent of the total network delay in previous approaches
