GETR Video Aware GigE Gateway Launched by Media Links
Stand 3.141, IBC, Amsterdam – 7th September 2007 - Media Links, a leading provider of high-definition video transport solutions, announced today the launch of its brand new GETR 4-port Gigabit Ethernet Transceiver with integrated optics. An important breakthrough forlong distance, high-speed, high-bandwidth video transport, this brings a level of flexibility and bandwidth control previously unseen for HD applications. This GETR contains an intelligent, video-aware, layer 2 Ethernet switch that manages bandwidth over Gig-E networks. Video and data signals from multiple input ports are combined into a single, high-speed Gig-E optical output. This bandwidth is adaptively controlled to give priority to video signals whenever they are present.Any remaining capacity on the output can be used for any type of IP traffic; this bandwidth can be automatically increased whenever capacity is no longer needed for video signals. This is a cost-effective, single card solution that perfectly dovetails with today’s broadcast networks. These converged networks must transport video and embedded audio signals with very low delay and minimal jitter connection to ensure that signals arrive at their destination with timing and synchronisation intact. Other data flows are managed through the use of Ethernet layer 2 flow control, to ensure that network capacity is not over-utilised. “Combining video, audio, voice and data traffic on a single network continues to be a goal for many broadcasters. Since many live video events last only for a brief period of time, networks that are dedicated solely to transporting digital video leave a lot of available bandwidth at other times. Media Links’ GETR solution breaks new ground with its intelligent control of data flows, providing broadcasters with a highly efficient, high bandwidth transport mechanism,” explains John Dale, Director of Product Management for Media Links. Key GETR Product Features/Benefits
§Two modes of operation can be configured: “VLAN mode” and “PORT mode”. In VLAN mode, priority can be assigned to the video traffic and provide provisioned bandwidth for specific VLAN Groups with Guaranteed QoS while other traffic is best effort. In PORT mode, video traffic is assigned priority based on port order from 1-4. §In each mode, non-video traffic speeds up to full bandwidth when video is not present at the input. §One optical transceiver port utilising industry standard SFP optics allows common sparing with other fibre transport equipment. The SFP port uses rate limiting in order to work in concert with packet limiting from the Ethernet ports so that the total ingress bit-rate of ports 1 – 4 match the limit set at the SFP port. §The MD-003 GETR can be used with Media Links HD-GigE compression codec and IP gateway together in the MD-003 carrier-class 1RU shelf to provide a compact, cost effective multi-service IP transport solution. The MD-003 GETR is ideal for HD, SD, DVB-ASI video transport over IPnetworks as wellas shared use with file transfer, VOIP, Internet access and other IP applications.
