The IF-442HD R81612 IPTV receiver is used for reception/decoding of television signals distributed in broadband IP networks, based on IP protocol and coded in MPEG-2 or MPEG-4 AVC/H.264, both in SD and in HD resolutions. A unique feature of the TERRA IPTV system is the fact that the terminal units - R81612 IPTV receivers - do not require any configuration, which can be of great importance in the case of larger networks. They automatically detect any changes in the local network or the programming.
