satellite savings, and improved subscriber loyalty,” added Pallett. “Thanks to HEVC, HD content should remain HD no matter what the delivery mechanism is — instead of being downscaled to cope with the network,” said Fouchard. It should also allow

HEVC for HD
While HEVC is seen as crucial for 4K, does it also have a place for HD? “The only application where it makes real sense is IPTV, to increase the reach of HD for existing clients. For satellite, cable and terrestrial

users who are already receiving HD, it does not make a lot of sense: the gain in bandwidth will not cover the cost of replacement of the STB,” said Boris Felts, VP product marketing, Envivio. Telestream has demonstrated “serviceable 500Kbps HD footage with HEVC which looks better than 1Mbps H.264. This translates to significant CDN and
broadcasters to optimise their HD output to look good on Ultra HD screens “as this source will constitute the vast majority of the content shown on the latest screens. The optimisation will consist of a pre-pre-processing option along with additional bit rate to add the fidelity needed to make an HD source look good on an Ultra HD when upconverted,” said Trow. For multiscreen distribution,
Nann expects HEVC to enable HD delivery to mobile devices without requiring more bandwidth. “For wireless and consumer network connections with bandwidth limitations, that’s an enabler of quality that couldn’t previously be achieved.” “H.264 compression is still getting more efficient and more cost effective as vendors continue
to introduce advanced H.264 coding tool-sets, with higher level of coding efficiency. HEVC will need to stabilise and be optimised within both hardware and software encoding systems as well as wait for CPU and GPU performance and cost efficiencies in order to become competitive with H.264 (even with the purported bandwidth gains),” said Peter Maag, CMO of Haivision. “Although bandwidth has not had the same exponential growth as CPU and GPU performance, it is getting cheaper every day with the advent of new technology and infrastructure. HEVC bandwidth advantage will for sure accelerate the HD adoption especially on mobile devices, however, the tipping point will happen when the bandwidth gains can at least offset the hardware equipment costs,” he added. “While the transition from H.264 to HEVC will be faster than the transition from MPEG-2, one needs to keep in mind that MPEG-2 SD is yet to be fully replaced by H.264 HD with many broadcasters.”
The world’s most advanced intercom solutions advance even further.
NEW!
The Eclipse HX offers a wide range of powerful matrix frames that are perfect for dynamic productions, enabling users to rapidly execute system changes and easily manage the confi g- uration software. The new Eclipse HX-Delta matrix system is a cost-effective 3RU intercom solution that can be conveniently installed in mobile trucks where space is limited or throughout a multi-level studio facility. This infrastructure permits shorter cable runs and puts broadcasters closer to their intercoms.
NEW!
With cabling simplicity, high channel density, and network capabilities, HelixNet Partyline is the leading digital partyline intercom for mobile sports productions requiring quick setup and multiple channels of intercom. The new HelixNet Partyline 1.1 enables linking between fi ve HelixNet systems to extend digital partyline communications to multiple broadcast sites over a network, eliminating the need for long cables runs. Up to 20 audio channels, fi ve program audios and power for beltpacks are supported over a single shielded twisted-pair.
