Media Links launches HD Compression Codec over Gigabit Ethernet into European Market
Stand 3.141, IBC, Amsterdam – 7th September 2007 - Media Links, a leading provider of high-definition video transport solutions, announced today the full launch of its HD-GigE Video IP Gateway solution into the European market. The HD-GigEIP gateway transports multiple HD-SDI/SD-SDI/ASI signals bi-directionally over IP networks and offers a cost effective alternative to traditional video transport services. This is the latest product in a comprehensive range of HD processing and transport solutions from Media Links.The HD-GigE delivers HD, SDI or DVB-ASI video signals over a standard Gigabit Ethernet interface providing IP network cost advantages and economies of scale.
The HD-GigE is capable of correcting packet loss as well as adjusting the IP bandwidth when video is no longer present. It combines HD compression technology and IP video encapsulation to offer the industry’s most robust HD transport solution, adapting HD contribution quality content to today’s IP/MPLS networks. With adjustable bit rate capabilities, HD-GigE allows links to be shared with other video signals and user IP traffic.
Offering a cost effective solution that fits both the broadcast and carrier industry, the HD-GigE is designed with advanced features such as variable compression bit rates, adjustable delay for automatic packet retransmission, auto detect and transparent pass-thru of SDI or ASI video signals in a 2RU shelf. Built-in web-server and SNMP MIB enables remote configuration and status monitoring. Standard definition and ASI signals are automatically detected and passed through transparently. “As the world migrates to IP networks, broadcasters and carriers alike are trying to take advantage of the economies of scale possible. Of course, compression quality is of fundamental importance. Media Links’ expertise in video and IP transport has facilitated the development of the HD-GigE product, one that allows optimum quality compression while taking advantage of IP network architectures,” explains John Dale III, Director, Product Management.
Key HD-GigE Product Features/Benefits
§Automatically transports SD or HD signals across IP network. Allowing broadcasters to send uncompressed SD or compressed HD signals over a single link without reconfiguration, simplifying operations and reducing system setup time. §Built-in error correction and packet retransmission. With short duration (single bit or packet) and long duration (up to one second outage) able to be corrected to deliver pure, uninterrupted video. §Advanced, standards-based compression for HD signals. Enabling up to three HD signals to be carried on a single Gigabit Ethernet link, increasing network utilization and reducing per-circuit costs. §Extremely low end-to-end delay (fewer than 16 milliseconds). Ideal for use in live broadcasts and two-way video interviews; eliminating the need to add audio delays to compensate for video compression delays.
June saw a successful European trial of the technology concluded at the TERANA Networking Conference in Lynby, Denmark. The Media Links equipment was purchased by the Friedrich-Alexander University of Erlangen-Nuremberg for use in conducting research in the multimedia networking and network measurement arenas. 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 layer-2 network connection at a distance of 2000km at various bitrates ranging from 251Mbps to 418 Mbps.
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.
