MDI measurement in the IPTV

IPTV is a system where a digital television service is delivered by using IP packets over broadband network infrastructure. IPTV can be operated through telephone line that is installed almost in all houses. Transmitted video streams take bandwidth and also need priority running in queue with other services in the providerpsilas network Such has in the effect implementation the quality of service (QoS) into network QoS mechanisms allow the best way to transfer to different traffics through the network Consumers want their IPTV programs to be smooth and visually excellent. From this perspective, it is specified as userpsilas quality of experience (QoE) that is the most important parameter for IPTV provider. Hence, network equipment must be rigorously tested that they fulfill QoE. IPTV is part of triple play offering that present high demands on the network such as is high bandwidth, low tolerance to jitter and packet loss. The media delivery index (MDI) measurement indicates problems generated on the network MDI gives an indication of real expected quality video (userpsilas QoE). MDI is independent on the video encoding.
