PRACTICAL METHODS to VALIDATE ULTRA HD 4K CONTENT Sean Mccarthy, Ph.D
PRACTICAL METHODS TO VALIDATE ULTRA HD 4K CONTENT Sean McCarthy, Ph.D. ARRIS Abstract Yet now, before we hardly got used to HD, we are talking about Ultra HD (UHD) with at Ultra High Definition television is many least four times as many pixels as HD. In things: more pixels, more color, more addition to and along with UHD, we are contrast, and higher frame rates. Of these getting a brand new wave of television parameters, “more pixels” is much more viewing options. The Internet has become a mature commercially and Ultra HD 4k TVs rival of legacy managed television distribution are taking their place in peoples’ homes. Yet, pipes. Over-the-top (OTT) bandwidth is now Ultra HD content and service offerings are often large enough to support 4k UHD playing catch-up. We don’t yet have enough exploration. New compression technologies experience to know what good Ultra HD 4k such as HEVC are now available to make content is nor do we know how much better use of video distribution channels. And bandwidth to allocate to deliver great Ultra the television itself is no longer confined to HD experiences to consumers. In this paper, the home.

High Definition Plasma and LCD Range Truly Advanced Viewing
High Definition Plasma and LCD range Truly advanced viewing In 1956 we manufactured the F-100, Hitachi’s fi rst television. Since then and throughout the past half century Hitachi has been bringing consumers across the world immeasurable enjoyment by providing the ultimate image technology and the best TV pictures. Hitachi is not only a manufacturer of televisions but also an innovator in television technology. This spirit of innovation has driven us to create unique and original solutions including the ALIS Plasma panel, IPS Alpha LCD panel and image processors. Hitachi continues to invest heavily in proprietary manufacturing of these cutting edge High Defi nition devices with new factories opening in 2006 and beyond to supply the growing world market for fl at panel televisions. Although we are a leading global company, Hitachi is swift to respond to the needs of local markets. Australia is at the forefront of High Defi nition digital television and in 2007 Hitachi offers a range of HD Plasma and LCD televisions with integrated High Defi nition tuners designed to Australian specifi cations. The future vision of Hitachi is to continue pushing the boundaries of High Defi nition image technology forward - “Inspire the Next”. 50 years of research and development; no wonder our visual technology is so advanced. What’s the difference? Plasma and LCD may look similar but their fl at screen and thin profi le is where the similarities end. The main difference between the two types of screens is the technology that powers their images. To produce an image Plasma uses tiny gas cells that are powered by precise electrical charges to produce the picture.
