theibcdaily 4K: “still challenges ahead” Conference Analysis By Chris Forrester
“Ultra-HD is really complex, and it is a new eco-system. 1080p is a good compromise until UHD/50-60fps 10 bit comes to life and including High Dynamic Range,” stated Thierry Fautier, VP/solutions marketing at Harmonic. “Silicon is starting to be available now for set-top boxes, and ready for 2015 deployment. But we still need to look further at standards, and aspects such as content protection need to be addressed before mass deployment can take place. There are still challenges ahead.”
Fautier was speaking at a fascinating IBC session produced in association with standards body ETSI, and
SilverBACK family grows: MultiDyne is demonstrating enhancements to its camera- mounted fibre transport product family, SilverBACK, which now includes four models. The versions are: the flagship SilverBACK-II; the SilverBACK-II-L for multicamera production; the SilverBACK-II 4K-L, a feature-rich model that includes Ethernet support and a video option for viewfinder or monitor viewing in the field, enabling camera operators to turn any 4K camera into a true Ultra HD multicamera production; and the SilverBACK II-4K, a low cost model without the viewfinder/monitor viewing option, designed to support traditional film-style productions. Frank Jachetta, president of MultiDyne, commented: “Other companies came up with this technology and it was great, very innovative, but they made BlackBerry. We have created the iPhone. SilverBACK looks like part of the camera.” Ultra HD support
chaired by ETSI’s Chantal Bonardi and which heard presentations on 4K’s technical demands, and the progress being made by NHK’s engineers on their 8K/Super Hi-Vision plans.
Fautier added that despite some examples of 4K streaming already taking place by the likes of Netflix, there were also good opportunities to ‘push’ 4K content to a consumer’s set-top box hard drive. “We see transmission demands settling at about 20 Mbps, and perhaps 25 Mbps in 120 fps. While this is demanding it is way below the 100 Mbps expected for UHD- 2/Super Hi-Vision, which is undoubtedly the nirvana and when we can all go home and retire!”
Further challenges were
thrown up by Pierre Routhier (VP/Technicolor) and his team,
who have been testing, comparing and contrasting the differences in spatial and temporal resolution when capturing content in 4K. “People seem to take for granted that when you go from HD to UHD it is simply a matter of changing cameras. This is not the case.” Rothier showed a variety of test shots, but admitted that
much of what he had seen suggested that good DoPs were going to be extra-busy on 4K shoots, especially OBs. He further confounded the audience by giving them some quality choices, only for the audience to discover that the best quality material, as far as motion blur was concerned, was achieved on ‘ordinary’ HD.

By Monica Heck
The new 2RU ViBE XT1000 Xtream high-density transcoder for live broadcast and multiscreen content has made its debut on the Thomson Video Networks stand.

new ViBE XT1000 packs the maximum number of channels into the minimum amount of rack-space,” explained Stéphane Cloirec, director of product management at Thomson Video Networks (pictured). The ViBE XT1000 supports up to 54 HD channels or 180 SD channels with transcoding from any format to any format including MPEG-2 and MPEG-4
AVC and is pitched at linear broadcasts on cable, IPTV, DTH and DTTV services as well as multiscreen delivery.
“This brand new encoder is also a crucial addition to our new ‘Behind Every Screen’ strategy,” continued Cloirec. “So far, the feedback from key accounts about our new strategy has been tremendous.” 14.A10
Expansion to Infinity: Vista V, a new 52-fader digital console has been unveiled at IBC. The Vista V features a built-in meter bridge, high-quality motorised faders, and a built-in Dynamic Automation system with DAW remote control. The console is fully surround-sound capable, with versatile panning and monitoring functionality. At the heart of the Vista V is the Infinity Core, which uses CPU-based processors to deliver over 800 audio channels and more than 5,000 inputs and outputs. It provides 12 high-capacity A-Link ports (1,536 channels per port) for D23m I/O integration or direct connection into routing systems or AoIP networks. Keith Watson, marketing director of Soundcraft Studer Professional (pictured left, with product manager Roger Heiniger), said the console was based on the same Quad Star technology as its predecessor the Vista X, but in a compact footprint that was more ideal for smaller studios, OB trucks and large live productions. The Vista V uses four processors to achieve high levels of redundancy in the control surface, while the CPU-based DSP makes it viable to provide two independent DSP cores running in parallel with instant changeover, without audio dropout. – Michael Burns 8.D60
