Media Links has claimed that the first long distance European trial of compressed HD video transport over Gigabit Ethernet has been completed, with its HD-GigE Video IP Gateway system, writes Fergal Ringrose.
Taking place at the recent TERENA Networking Conference in Lyngby, Denmark, the HD transmission circuits were set up between Friedrich-Alexander University and the Technical University of Denmark. The HD-GigE encoders transmitted HD-SDI video over a 2000km-long, layer-2 network connection at various bitrates ranging from 251Mbps to 418Mbps.
"We are extremely excited about the successful conclusion of this test. There are many applications for this technology including the live contribution and distribution of video, IPTV content backhaul and local/wide area content exchange, to name but three. It provides a viable alternative to costly existing solutions," explained John Dale III, senior product line manager, Media Links.
The HD-GigE combines HD compression technology and IP video encapsulation to offer a robust HD transport solution, adapting HD contribution quality content to today's IP/MPLS networks. With adjustable bitrate capabilities, HD-GigE allows links to be shared with other video signals and user IP traffic.
Offering a cost-effective system that fits both the broadcast and carrier industry, the HD-GigE is designed with advanced features such as variable compression bitrates, adjustable delay for automatic packet retransmission, auto detect and transparent pass-through of SDI or ASI video signals in a 2RU shelf. Built-in web-server and SNMP MIB enables remote configuration and status monitoring.
