broadcast manner. For London the intention is to create the same content but not rely on broadcast systems for anything other than creating the live TV product. We will produce rough cuts from the digitally encoded stream for 100% of our on-demand video content and make those clips available across devices without touching the broadcast environment.” “We need to produce digital
like TV, which means ensuring that the TV pictures have a digital story running in parallel to it,” says Silver. “We are trying to keep users engaged in content regardless of the platform it is viewed on so that the two media complement each other. One of the areas where we continue to struggle is scalability. While OBS provides a great deal to rights holders, the onus is still on us for video streaming, for example, so picking a partner which allows you to scale without significant capital expenditure is important.”
Remote production Net Insight says it has received orders from several media service providers to deliver its Nimbra multi-service core switching (MSR) platform to handle video transport between major broadcasters and the TV/media centre. As a specific example, the Nimbra MSR platform will be used by Swedish telco TeliaSonera International Carrier, to deliver remote production of the Games for clients over its fibre-based media network. TeliaSonera is providing
broadcasters from Scandinavia, Japan, Korea and Brazil, access to eight TV studios located at the edge of the Olympic site to create content for their Olympic coverage. From the studio facilities, broadcasters will take live studio feeds, routed over TeliaSonera’s network, to a centralised location within the broadcaster’s headquarters. “This saves money and time in
terms of not having to send an OB truck and OB production
team on-site,” says the telco’s UK MD Dan Pope. “Studio personnel can access content anywhere, on an as-needed basis, enabling the studio crew to remotely control, produce and edit media content seamlessly over a virtual studio network.” The solution is able to provide
a realtime, low latency network technology that enables centralised production and remote workflows with the same quality as if they were on site. “People have done this on
metro area fibre, but this will be the largest distance anyone has done long haul,” says Pope. “When you look at this concept in detail we are providing an exact replica of what would normally be done in an OB truck. Graphics and other parts of the process have typically been added remotely but the difference here is that literally every single function in a truck can and has been moved to wherever you want it. “You can only do so on a fibre- based network and compressing using JPEG2000 (not MPEG-4). Even though a four-camera production does use up a bit more bandwidth, JPEG2000 is incredibly suitable for this sort of application because of its low latency and minimal delays.” The latency between London and Stockholm over fibre, said Hope is “the odd millisecond. London to New York around 70ms and further afield 300-350ms. By contrast, satellite would be longer.”
Multi-screen delivery NBC will deliver its most extensive Olympics coverage to viewers, with all events streamed in realtime on at least one of its platforms [Ed Note: See also ‘NBC Highlights Factory: Nonlinear content delivery for London 2012 on page 18]. Live streams will be available across NBC’s mobile platforms, offering 360˚ coverage. Helping the broadcaster achieve this are a clutch of Harmonic storage and transcoding products.

Simultaneously, those full- resolution recordings will be replicated and transferred by Harmonic’s ProCast IP acceleration solution over a 10G circuit to a 432TB MediaGrid system at NBC’s 30 Rock facility in New York City. In both London and New York, ProMedia Carbon will perform transcoding of content on the MediaGrid systems. Avid’s Interplay media asset

The resulting shotlists will be sent out to distribution outlets or delivered to edit rooms when needed for broadcast. In addition to the MediaGrid

EBU bringing London 2012 to huge European audience
By Melanie Dayasena-Lowe
THE EUROPEAN Broadcasting Union is set to bring European viewers more live Olympic and Paralympic coverage on television, radio and online than ever before.
Preparations are underway at the International Broadcast Centre in London, where the EBU and its Members occupy more than 1km sq of floor space. From there, the EBU will be running 12 simultaneous
multilateral transmissions and three unilateral feeds for up to 13 hours a day for the duration of the Games. This comprehensive set-up will ensure that more than 70 rights holders will have the pick of all 40 sports on offer.
MediaGrid storage systems will operate with Avid edit and media management platforms to facilitate a file-based highlights production workflow in which multiple editors can instantly access content.
Incoming HD content from various venues will be recorded
EBU President Jean-Paul Philippot said: “The EBU provides reliable, flawless delivery of live premium sports to the broadcasting industry, and it is an honour to be able to demonstrate this at the London 2012 Olympic Games. We have grown alongside the IOC since 1956, and the EBU and its Members will provide for these games the most extensive coverage on all media platforms more than ever before.”

footage available over the course of the competition. Ericsson is also providing a
range of products to NBC Olympics including MPEG-4 AVC encoders, receivers, multiplexers and satellite modulators as well as a team of support engineers in both London and New York.
The EBU will also provide Member reporters, commentators and technical staff with any space, equipment and logistical support they need in London to cover the Games for their home nations. EBU Members are planning to produce thousands of hours of programming, which will be distributed across all media to an unprecedentedly large audience.
