Until issues beyond resolution are addressed, the appeal of Ultra-HDTV will be limited says Ian Trow, senior director emerging technology & strategy, Harmonic
Going into IBC2013, ultra high-definition TV and 4K undoubtedly are garnering the greatest attention and fueling the most discussion. Ultra-HDTV is promising, particularly for applications such as sports coverage, but the reality is that unless and until fundamental issues beyond resolution are addressed, the appeal of Ultra- HDTV will be limited to the relatively small market comprising home cinema enthusiasts who would welcome the increase in resolution at frame rates typical of cinema material. As with the rise of HD not that
long ago, workflows and interfaces for Ultra-HDTV must be adapted to allow the improved resolution to work for a variety of formats, long- and short-form. Professional and consumer interfacing must support not only high resolution,
but also improvements in bit depth and frame rate, which are critical to enhancing the Ultra- HDTV experience. Ultra-HDTV will be a success
when it has made the transformation from a home cinema format to a true upgrade from HD in the living room, and this will not happen overnight. In the meantime, as the practical matters surrounding Ultra-HDTV production and distribution are addressed, the current market environment offers media companies the opportunity to improve the quality and competitiveness of their HD offerings. Increases in quality of experience (QoE) for HD in over-the-top (OTT) applications are leveling the playing field for linear broadcast and the various on-demand services gaining a significant foothold in the market. For HD and multiscreen services, as well as future
Ian Trow: ‘HEVC will play a key role’

delivery model today — and support emerging models that leverage technologies such as the MPEG-DASH streaming and HEVC compressions standards for even greater efficiency gains. Continued development of
Ultra-HDTV services, HEVC will play a key role in reducing bandwidth requirements and in enabling additional services. In so doing, the compression format also will help to address the significant OpEx and CapEx issues currently facing network operators. Already, demonstrations have shown that with the new HEVC (H.265) standard, rather than
its predecessor (H.264), Ultra- HDTV is viable at bandwidths today used for HD services. IBC2013 attendees can
expect to see for themselves the remarkable quality of UHDTV, as well as the technologies that will help make it a widespread success. In fact, the show will feature solutions that address virtually every media production and
technologies that enable local broadcasters and advertisers to reach differentiated viewers with targeted content or advertising is an important though less glamorous trend shaping the industry now. IBC2013 will surely feature a broad range of solutions designed to aid local service providers in using new services – linear broadcast or Internet- delivered — to boost their revenue streams. Because multiscreen media
delivery is here to stay, media companies large and small also will find an array of solutions that enable more efficient multiformat content production, more cost-effective distribution of content over any network, and better support of high quality video delivery, regardless of the display device. 1.B20
