A record number of us across the world have been glued to an amazing two weeks of Olympic sporting action. The cameras have stopped rolling, our sporting heroes have been welcomed home and the NBC Sports' team has checked out of the International Broadcast Center (IBC). The 2016 Rio Olympics is over and thousands of hours of world-class sporting action stored on hundreds of LTO tapes has been packed up and taken back to NBC's Stamford, Connecticut HQ. Like checking out of a hotel after a two week vacation, they don't want to leave any of that precious material behind.

Rio really has been a carnival Olympics, not only smashing records on the track, in the velodrome and in the pool but also behind the scenes. A staggering 350,000 hours of coverage has been shown London 2012 saw less than 200,000 hours. In a short four-year period how has this coverage increased so significantly? First, two new sports - golf and rugby sevens - were seen for the first time at the Games; second, there's been a vast increase in 4k capture; and finally, this year's event saw more digital coverage than ever, nearly double the amount of TV coverage and 2.5 times more than London 2012 (218,000 hours versus 81,500 hours). NBC exceeded a staggering 2.5 billion live streaming minutes, over one billion more than all previous Olympic Games combined.
Creating the world's biggest live television event comes with a lot of pressure and as a long time host broadcaster NBC Olympics has to ensure that the technology that it has in place from acquisition through to delivery is first-rate. One of the key elements of the workflow is the SGL FlashNet archive, which NBC Olympics first started using in Athens in 2004. Much of that content, is still regularly accessed, having been automatically migrated across generations of physical storage by the sophisticated content management software that is, SGL FlashNet.
On a day-to-day basis parent broadcaster NBC has a large SGL archive implementation at its Stamford HQ, which it uses to store material for its whole operation, fully implemented with Avid's Interplay PAM and MAM systems. When the Olympics come around every two years, that FlashNet system is extended out to the host country. This means that the editing teams around the world can easily reach back into the archives in Connecticut and pull that all important historical media. For content produced in Rio, NBC Olympics sent a small SGL archive that took all the feeds for the hundreds and thousands of hours of recordings that NBC made, and stored them on two 50 slot, 4 LTO drive libraries. The SGL FlashNet system is capable of storing nearly 4,000 hours of XDcam HD material every day even in this compact hardware configuration.
At the planning stage NBC Olympics decides which material will be archived or deleted at a later date placing flags within the metadata. During the event, as the SGL FlashNet system processes through each day's media it looks for material that's flagged to be archived and writes those terabytes of data onto the LTO tape. Jim Miles, Director of Digital Workflow Systems at NBC Olympics says, The SGL archive was pushed really hard throughout this event, processing thousands of jobs per day up to 600 jobs per hour which is really telling of what the system can do. As well as this powerful processing capability it also provided us with access to historical Games so we could pull content from London, Beijing, Sydney and Atlanta to integrate into the stories that we were telling even before the Games had started. Once the Games began, we logged every aspect of the competition so we can tell that story again next time. This workflow isn't just for the Olympics but all our other entities such as NHL and NFL; we go back to the archives constantly.
Enabling feature producers to easily pull historical material from the archive is a key part of the NBC production workflow. Traditionally pulling material from the US to the host nation in this way was an expensive and time consuming process involving a transmission operator, feed lines, encoders, satellites and a number of other components. Miles says, In years gone by it would take ten or fifteen people to make that happen. Now using the MAM and the SGL archive, producers can find the shot, pick off the chunk they want, quickly send this to the venue using file acceleration, restore that material and all the other components from FlashNet and within a few minutes they have that shot within their editing system.
Partial file restore, which is supported by both the Avid Interplay PAM and MAM workflows is a key element of the NBC Olympic workflow. Many of the recordings are much too long to be pulled back into the edit when often all that's required is the 30-second shot of the goal or the climax of the race. Built in intelligence within FlashNet's data handling components read and log the metadata held in the MXF or QuickTime wrapper as it's written to the archive. This information is then passed to the FlashNet database for later use when only a small portion of the original material is required.
Every two-year cycle brings about new technology features and Rio was no different. In Sochi, NBC Olympics had a separate archive from the production system, in Rio the search capability, the systems and the database were all fully integrated so the operators could log into a single tool and search for assets from that day or ten years ago, within the same result set and the same interface. Miles explains What we've been doing the last 18 days has never been done before, it's the biggest television event that we've produced, it's the most content we've ever pr
