Media Links was selected by Telstra for Australia’s next generation digital network for broadcasting. Telstra is the leading telecommunications and information services company in Australia. Media Links AU serves as Telstra’s main contractor for its DVN2 build-out and expansion, and supplies advanced network management software, Media Link’s flagship media over IP transport solution, the MD8000, installation services, operational support and continuous system maintenance.

The project has replaced the existing digital video network and covers hundreds of locations across Australia.

Media Links’ MD8000 Video over IP transmission technology was implemented as the high quality transport technology platform for the 2014 World Cup event. A total of 24,400 minutes, approximately 406 hours of television transmissions were managed under demanding conditions throughout the games. The Media Links solutions provided 100% uptime and zero packet loss of all TV signals. This extraordinary task was due to a combination of Media Link’s advanced technology, an experienced Media Links support team and customer technical team, as well as the expertise of system integrators, VIDI, a long-time Media Links partner.

The Media Global Links MD8000 video over IP media transport solutions was installed and deployed in 17 venues throughout the Incheon Metropolitan Area to facilitate the live broadcasts and content transmission throughout the 2014 Asian Games. The MD8000 family addressed the need for carriers to connect directly to IP networks for long-haul, multiple-wavelength transport links, which resulted in significant cost savings.

The MD8000 solutions aided in the media transport of 52 games, 6 stadiums, with more than 250 hours of live transmissions. Not a single second of signal failure ensured 100% availability. This LIVE-TV transmission project was managed by Media Links’ EMEA partner, VIDI.

The selection of the Media Links solutions for all the contribution links for EURO 2012™ can be attributed to the extremely high quality and reliability of the Media Links equipment, and to the excellent support offered by Media Links’ partner, VIDI for the systems design, installation and support. The MD8000 is particularly suited for this type of application as it offers high levels of redundancy to deal with external problems such as loss of fibre links, as well as very low latency to allow operators and talent to work in a live situation with the delays of many compression systems.

Since 2011, Media Links has provided real-time video over IP transport technology & solutions, as well support for the HD broadcast of Australian Football League games (Australian Rules Football). The fibre based contribution network allows multiple tenants to dynamically access the feeds from various stadiums throughout Australia through elegant NMS switching. A visually lossless JPEG2000 compression codec is applied for the efficient use of bandwidth. The redundancy in network architecture and ‘ hitless’ protection have ensured 100% QoS (Quality of Service) for all the HD and data services provided for the games.

The Commonwealth Games are a major live event produced and distributed entirely over an IP network. Media Links along with European partner, VIDI implemented the equipment and support services to help make this possible.

A major network provider launched their next generation video over intelligent optical mesh  network in 2010 using Media Links MD8000 technology, and in 2013 provided a  full uncompressed HD-SDI feed with dual diversity and hitless switching for “The Big Game” XLVII feed.

In 2010, Media Links provided an industry first at “The Big Game” XLIV, by transporting an HD-SDI feed with the use of JPEG2000 compression over a major network’s intelligent self-healing optical SONET mesh network. The signal was transported directly from Miami’s Sun Life Stadium via OC-12 interconnect to the core long distance network and the CBS studio in New York City. The same JPEG2000 encoded HD-SDI signal was transported with Media Links MD8000 solutions to CBS’s disaster recovery facility in Los Angeles. The signal quality and network latency for both HD-SDI feeds proved to be the most efficient and reliable means of transporting a native HD-SDI signal over a high profile Network Provider’s long distance video network.

Media Links and Level 3 provided the first live uncompressed bi-directional HD-SDI video service over IP from Invesco Field to CBS New York throughout the duration of the 2009 NFL season.

The Media Links video transport solution has been deployed throughout the Verizon tariff video footprint for the backhaul of uncompressed HD, SD and DVB-ASI video signals throughout major Metropolitan US cities. The Media Links solutions have been associated with major events such as the 2009 Presidential Inauguration and high profile sporting events.

Turner operates an entire channelized OC-192 video and data transport network between New York, Atlanta and Washington D.C., where the Media Links compression technology is used for the adaptation of HD-SDI to their SONET backbone. All live CNN HD video feeds are handled by Media Links MPEG-2 compression. Internal to Turner’s broadcast facility, Media Links provided one of the highest quality HD-SDI up and down-conversion products available.

Media Links were awarded the contract from Televisa to upgrade their existing transport infrastructure to support full HD-SDI in order to deliver the highest quality of video prior to network distribution. The MD8000 provided Televisa a fully protected 40Gb ring topology, future expansion capacity up to 200Gb per location, and hitless switching for all video and data traffic. The network has been in operation since 2009, and was associated with the world’s first 3D broadcast of a soccer game held in Mexico City. In 2011 Televisa expanded their existing MD8000EX deployment by adding an additional shelf to increase the range of signal distribution.

In 2010 TV Azteca in conjunction with Iusacell broadcast the final episode of Mexican Idol using the MD8000 video and data transport platform. The system was configured with Gigabit Ethernet interfaces and successfully transported DVB-ASI signals over the Iusacell MPLS IP network.

TV Azteca have deployed the Media Links metropolitan fibre transport solution to deliver HD-SDI and compressed DVB-ASI signals to several of their key transmission facilities. The Media Links solution offers a seamless transition between DVB-ASI, SDI and uncompressed HD video signals by automatically detecting the video format. TV Azteca leveraged their existing HD contribution infrastructure by seamlessly integrating the live uncompressed events back to their main production facility.

The network has been in operation since 2006, and the Media Links equipment has performed flawlessly with no signal interruptions or hardware failures. TV Azteca also upgraded a large portion of their network to the MD8000 platform in preparation for future HD expansion throughout their broadcast facilities.
