As the industry advances to MPEG4 HD and looks to HEVC, codec power and versatility are critical says Christophe Delahousse, president, Thomson Video
From our position as a longtime provider of solutions that enable transport of professional-grade SD and HD services, we’re seeing that the ongoing evolution of encoding is coupling with advances in contribution and distribution solutions to effect significant change in the services that broadcasters and other media companies can offer. The result for our customers is the ability to deliver superior-quality video – and, often, more of it – to anything from small handheld devices to large 3D HD screens, with the low bandwidth essential to realising a profitable business model.
At this point, the majority of content
created is HD, and the majority of viewers consume content on HD displays. The bandwidth demands of HD are pushing broader use of HD-SDI or 3G infrastructure and more cost- efficient contribution codecs. As the contribution and distribution world migrates to HD, the move to MPEG-4 is helping to reduce transport

costs, even if a large part of a company’s installed base remains MPEG-2 SD/HD. We have extended our product portfolio to address this approach, offering the ViBE CP6000 contribution and distribution platform — a dense, modular, and versatile codec (from MPEG-2 SD 4:2:0 up to MPEG-4 HD 4:2:2 10 bits) — along with IRDs and network adaptors that improve delivery of quality live video. Increasingly sophisticated and powerful compression technology, such as our Mustang 2.0 compression technology, within HD encoding systems is
allowing broadcasters to deploy more HD and SD channels within existing bandwidth limits. With its potential to reduce bit rates by as much as 40 per cent, the new High- Efficiency Video Coding (HEVC) standard promises to help drive down bandwidth requirements – and fuel further improvement in H.264 encoding already so broadly adopted across the industry.
In the near term, the promise of HEVC, a progressive-only technology, may be tempered by the practical and economic considerations of employing a new compression standard.
While codec power and versatility are critical, media companies also are finding that they the integration of ancillary services within the multiplexing pool brings valuable added efficiencies. At IBC2012 we’ll demonstrate how our new Flextream 2.0 statistical multiplexing technology frees up bandwidth provisioned for the processing of non-video components such as audio, teletext, subtitling, and closed captioning, allowing it to be reallocated to improve video quality. Finally, but equally important, IBC2012 will be a showcase for technologies that support web TV, over-the-top (OTT) services, IPTV, and cable delivery. Recognising continued opportunity for our customers we will present the ViBE VS7000 multiscreen video system, an ‘anything in, anything out’ platform that delivers outstanding picture quality in an

all-IP environment with live broadcast- quality encoding and faster-than-real-time file transcoding. Flexible technology such as this is
proving vital for those companies that wish to keep pace with the rapid rise in ‘TV everywhere’ consumption and effectively address the consequent change from a linear pattern of viewing to something much more diversified. 14.A10

ATG Broadcast is showcasing its full range of systems planning, design, installation, commissioning and post-installation support services. Recent contracts include playout facilities for the new HD2 Sports channel at the Stockholm headquarters of TV4 Sweden; a networked ENPS newsroom for South African Broadcasting Corporation (SABC), the world’s fifth largest of its kind; a five-camera production studio and file-based ingest system for Arab Radio & Television, forming the technical heart of a new site in Jeddah; an
insert studio at the London offices of a global financial services corporation; as well as an engineering test facility for Snell, centred on its Integrated Content Engine playout system and driven via Morpheus automation. “Although it is easy to get enthusiastic about new
developments like 4K and 8K super- high resolution, ” said ATG Broadcast MD Graham Day, “many channel managers will be attending this year’s IBC with a quite different priority – how to get the maximum economic and operational benefits from modern file-based programme-production, editing, archiving and playout systems.” 8.B51
Voice-over-IP Stacs up
Comrex By David Fox
STAC-VIP allows broadcasters to benefit from the change to Voice- over-IP telephony, as it integrates legacy PSTN/POTS lines with VoIP to deliver a new way to manage telephone calls for talk shows, interviews and contests. It can handle calls from HD Voice-capable phones offering 7kHz audio or high- quality calls from Skype users,
making it useful as a central hub for reporters and citizen journalists. It can process up to 12 incoming
VoIP calls on a single DSL line using telephone-grade G.729 audio compression, potentially providing huge cost savings. POTS and ISDN lines can be accommodated via VoIP Gateway devices that provide conversion of POTS/PSTN, ISDN and T1/E1 telephone lines to a SIP- compatible VoIP trunk for connection to the STAC-VIP Mainframe. 11.G11
