News production, using tools like Newsbox, could be transformed by simply moving the frames you need, when you need them

“The AS-02 bundle is as rich as the Quantel Enterprise sQ format,” he said. “QTube [Quantel’s distributed production system] now puts AS-02 ‘in the cloud’, so you can edit anywhere.” Essentially, an AS-02 bundle of one frame plus all its links is the building block of the internet of frames, and could potentially be accessed and used by any vendor keen to go down this route. One of the sets of links that might be implemented would be to have a single reference for a frame, but with the capability of actually calling the browse proxy, SD, HD, 4K and more versions. So a journalist could edit a package on location, or a producer work on a train, then publish the story simply by emailing the EDL. At the next point of use — which could be transmission — the same frames are streamed in over HTTP but using the appropriate resolution versions required by that process. The logical extension of that is to see the end of the traditional broadcasting centre. “We can keep all our content in a rack of servers in a data centre,” Cartwright asserted. “We only need one kind of cabling – ethernet. We could deploy the resources we need by swiping a credit card to buy time.” Rather than have dedicated, high performance video servers in a playout centre, the frames are streamed — by virtue of their links to the next frame — to the encoder or transcoder as required. Broadcasters could move out of large city centre buildings to become virtual businesses, working with any media and publishing to any platform without ever needing to know where it is stored. One of the other questions
raised about the cloud by content owners is security. How could we trust a virtual broadcaster such as this? “We trust online banks,” is Cartwright’s response. “In the end we need to secure people, not devices.” Ultimately, the internet of
frames offers the opportunity to move away from the content factory approach. This involves tracking multiple variants of each file, some of which may be rarely if ever used. As content is edited, so the number of variants to be tracked is multiplied. “The management problems explode,” said Cartwright. “You end up
and store all the intermediate forms? Why not pull what you want, when you need it?” So is this a vision of content management in the future, or a
concept doomed to failure through a lack of
understanding? Cartwright promises that “the Quantel vision will be filled in over the next year.” He and his employer are clearly putting a great deal
of faith, and resource, behind the concept. For now, the company is doing all it can to evangelise the idea that the cloud can work for broadcast, with the scalability of the internet
promising to deliver all the capabilities and capacity we need. “We just need a different identity model,” Cartwright concluded. “We should not be bound to files, we should be bound to relationships.”
