Centralparq from new business Infostrada is already providing a platform for content management and exchange
The file metaphor
While we are still in the world of files, LTFS is fast emerging as a secure way to store and exchange content. SGL reported that in practical tests on the stand they had brought in tapes from other vendors and read the content with no problem. According to Quantum, “the beauty of LTFS is that it is like a USB drive: you drag-and-drop your assets on any device”. iStreamPlanet was focusing
on live streaming, which it said faced three technical hurdles: live video requires expensive hardware encoders; it is a complex workflow to manage; and viewer expectations are high. It claims to have solved these issues with Aventus, a software product that is scalable up to thousands of live channels, running in virtualisation on commodity hardware. Even more ingenious in its use
of standard hardware was the nanoCDN from Broadpeak. The company rationalised that modern set-top boxes and home gateways are servers in themselves, so why not use them as a massive cloud content delivery network. Given the way that telcos are suffering from media traffic clogging up the networks, it is a neat way to ease the load and offer CDN services direct, allowing them to compete on price.
Last, but absolutely not least,
a really exciting glimpse of the future from Axon, pointing to “the end of SDI”. Using the emerging IEEE AVB (audio video bridging) standard, video can now be moved over an IP fabric, with timing accurate to less than the SDI jitter specification. The Axon demonstration was set up for a uniform 2ms latency, which allows for complex switching. So no more specialist routers: just use an AVB compatible ethernet switch. A 48 port AVB- ready 10Gb ethernet switch is currently around $15k but that price will tumble. As Axon’s Jan Eveleens pointed out to me, the worldwide market for ethernet switches is 20 billion a year, so R&D is readily available and commoditisation is fast. Terabit ethernet is on the horizon. Axon promises its Synapse range will be completely AVB compatible by next NAB. Audio vendors already offer AVB products, and you can be sure that other video companies will follow Axon’s lead. Who needs the glamour of
4K when there are two seismic shifts in infrastructure: Axon showing the end of SDI and Quantel questioning if replacing it with the file metaphor is the right way to go. There is plenty of excitement left in the underlying technology.
IMT and Dejero THE DEJERO + Nucomm Connect Live transmitter is a camera-mounted bonded cellular and microwave system for electronic newsgathering (ENG), a combination of Integrated Microwave Technologies (IMT)’s coded orthogonal frequency division multiplexing (COFDM) technology and Dejero’s adaptive bitrate cellular bonding technologies and portal management system. The Connect Live transmitter
is manufactured by IMT. “Our effort is basically on the hardware,” said IMT vice president of operations Todd Hansen. “There are eight antennas designed into the housing for bonded cellular, four different cellular providers, four modems. In addition to that we’ve added a COFDM microwave link as a backup.” Connect Live is powered by
Dejero’s LIVE+ Core Software. “What we brought to this partnership was our bonding technology that bonds all those
Todd Hansen and Todd Schneider with the Dejero + Nucomm Connect Live transmitter
modems,” said Todd Schneider, COO, Dejero. “We can put up to four LTE modems in there. As well there are Ethernet connections on the product, which we can bond. There’s also built-in Wi-Fi, so we can bond all those connections together and use them all at the same time.” For day-to-day news coverage, users can employ the bonded 3G/4G links to transport live HD video back to the station. The transmitter features adaptive bitrate and bonding technologies to compensate for
changing network conditions by adjusting frame rate, resolution, encoding rates, and streaming parameters. This enables the system to bond up to four cellular 3G or 4G LTE networks, as well as any combination of Wi-Fi, Ethernet or Ka-band satellite to provide maximum throughput for video transmissions. The Connect Live device has a boot-up time of less than 30 seconds.
