IP for live production

The production and transmission of a live sporting event is one of the most technically challenging assignments for any crew. After all, you can't ask to take the shot again at a live event! Multiple signals in a variety of formats need to be transmitted around the sporting venue, as well as being seamlessly integrated with feeds from a studio or other locations to form a complete broadcast stream.

Managing the various signal types and locations can be challenging; most media signals need to be encapsulated or adapted to work efficiently over a backbone that carries multiple signals. However, by taking advantage of the latest IP technology, networks can be simplified by consolidating all media traffic onto a common platform.

This in combination with the falling prices of bandwidth plus the increased quality in video codecs and ultra-low latency delivery across WAN network infrastructure, means broadcasters no longer need to carry the high cost of producing live events on-site. The good news is that the technology is now available to enable broadcasters and network providers to convert and move the complete suite of broadcast signals - whether video, audio or data - onto their multi-service IP/Ethernet networks.

By using this remote production model, both 4K/60P, HD-SDI/3G-SDI camera feeds and data traffic can be sent from the remote venues directly to the studio, where all production and editing can take place. There are numerous advantages including the fact that editors can utilize more sophisticated in-studio tools across the board. It also reduces or removes the need for broadcasters to have full capability production trucks and large crews on-site at the venue, therefore, greatly reducing their operational costs. This is particularly relevant to the production of smaller-scale events, as costs can be held low while at the same time increasing the overall production value.

The Remote Production over IP model is supported by Media Links MD8000 products that provide high quality and low-latency solutions for moving multiple paths of video content encoded using JPEG2000 and sent as Ethernet frames over an IP network. Sync is ensured over multiple points on the network, using IEEE 1588V2 Precision Time Protocol.

Media Links MD8000 video over IP media transport and switching solutions combined with the Company's state of the art Network Management System provide an efficient, seamless and highly reliable way of moving content between shooting locations and the broadcast studio. The utilization of bandwidth is enhanced and media connectivity can be maximized over the entire IP network and over long distances.

The Company's solutions are deployed globally by broadcasters, and major telco's and have been used to provide live content contribution for the Sochi Winter games and World Cup soccer, experiencing 100% uptime. In fact, Media Links has an installed customer base of over 1000 sports venues, serving customers on six continents, providing backbone technology behind many major events around the globe. Come and discuss how we can help you move your content over IP, on booth SU4721 at NAB 2016.

Trade shows and their role in the wired world
Richard Baker Historically trade shows afforded an opportunity to collect the latest brochures relevant to the visitor's chosen industry or career path. Today there seems little reason to store data of any kind, let alone paper brochures, when information is so easily accessible online. Brochure back-packing at exhibitions has become a rare sight, rarer still since the security clampdown on visitor luggage at exhibitions. Today's efficient show delegate need only carry a mobile phone and, in deference to tradition, a bundle of business cards. The phone doubles as a snapshot camera, video camera, dictaphone, email reader, internet browser, Skype communicator, and so on.

Emma Morrison When Nigel Woodford started his career at BBC Wood Norton in 1962, television was black and white and BBC Two had not yet been launched. In 2018 Nigel will retire, and Richmond Film Services, the pro-audio equipment rental company set up by Nigel in 1973, can count numerous contributions to iconic moments in British cultural, sporting and film history over this time.

What is next in OTT
Mary Kay Evans In the past year alone, we’ve seen a substantial increase in the amount of OTT content that’s being streamed. In the first quarter of 2018, there’s been a 114 percent year-over-year growth in streaming video hours, and those numbers are only expected to rise. With OTT revenue predicted to reach $16.6B in 2018, a 40% gain over last year, there’s no question that OTT is booming, and that there’s never been a more critical time to pay attention to the space.

The Pace of Change
Dick Hobbs - new

The youngest human to stand on the moon (so far) was Charles Moss, the lunar module pilot of Apollo 16. Charlie had a wonderful claim: his father witnessed the Wright Brothers’ first flight at Kitty Hawk, and lived to see his son on the moon.

Does anything capture the speed of technological advance better than that? The whole of the history of powered flight in one lifetime.
