TECHNOLOGIES Thierry Fautier Vice President of Video Strategy at Harmonic and President of the Ultra HD Forum Navigating the Ultra HD Frontier How to Deliver Live Content With Minimum Bandwidth Consumers are lighting the path toward worldwide acceptance of Ultra HD (UHD). Recent research from Eutelsat Communications revealed that consumers are willing to pay up to 10 a month to beneﬁt from the increased sharpness, immersion and vivid color that UHD content offers. They’re also willing to invest in new UHD TV sets priced between 1,000 and 3,000 for screens within the 50-inch range. The same study found that pay-TV subscribers showed a strong preference for linear UHD channels, while viewers that have cut the cord expressed a preference for VOD and occasional, event-speciﬁc content in UHD. UHD television sales are expected to skyrocket While consumer interest has been peaking, the challenge with UHD, thus far, has been delivering UHD content in high quality using minimum bandwidth. This article will examine the hurdles video content and service providers face when delivering UHD content, the current state of UHD deployments and future technology advancements on the horizon for this exciting new video format. UHD Roadblocks There are several roadblocks that stand in the way of UHD services being deployed on a global scale, including absence of a single UH standard, lack of a deﬁned workﬂow for UHD production and delivery and shortage of infrastructure bandwidth. Right now there are several standards bodies, forums and alliances working on deﬁning an UHD proﬁle. The Ultra HD 58 | KITPLUS - THE TV-BAY MAGAZINE: ISSUE 108 DECEMBER 2015 Forum is one group making signiﬁcant headway. Currently, the Forum is in the midst of setting up guidelines for UHD technologies such High Dynamic Range (HDR), High Frame Rate (HFR) and Next generation Audio (NGA). In addition, the Forum is looking to outline an end-to-end video production and delivery chain for live and VOD UHD services. Additionally, the High Efﬁciency Video Coding (HEVC) codec has emerged as a viable solution for bandwidth compression, allowing video content and service providers to deliver superior quality services such as UHD using the same amount of bandwidth. Once the industry agrees on an UHD proﬁle and workﬂow for end-to-end production and delivery, and incorporates HEVC solutions into their architecture, pay-TV operators can move forward with introducing UHD offerings. Fixing the Bandwidth Issue To date, UHD service offerings have been slow to market. Most UHD content today is viewed as VOD via OTT service providers. However, that may be changing
