Analysis of quality parameters influence to translation of IPTV service

The most important for everyone of people to have good time and relax during TV translations in the work day evening. Nowadays interactive TV, as IPTV (Internet Protocol Television - digital television, transmiting over IP networks) is very popular in each country. TV signals for end-users are transmitted by broadcast Internet network, using Internet protocol (IP). The most important for end-user is receiving qualitative IPTV service with no any interference during TV translation. One of the most impact for qualitative IPTV service is effective and optimal assignment of data streams. It depends on processing time of data streams in nodes of network. Operative assignment of data streams is a critical problem for qualitative broadcasting of IPTV service. In this paper we analyse the assignment of data streams in core and access networks, influence of intensity and delay for assignment of data streams in different nodes of real and simulated IPTV networks. The main results showed that the efficiency of real IPTV network is less than efficiency of simulated IPTV network.
