But we don’t broadcast in a Million 80p, do we? (No but some day soon UHDTV is coming)

But we don’t broadcast in A Million 80p, do we? That funny commercial from DirecTV as shown here from YouTube. No, they don’t broadcast in A Million 80p - and neither did they just level the playing field. But coming soon, maybe in 10 or 15 years (or sooner?) there may be even “Higher Definition TV” called UHD - Ultra High Definition. I found this while reading some additional stuff related to my last post on DVD Upscaling and while reading about Movie Production with High Definition Video Cameras (1080/24) that are starting to beat 35mm Film for producing movies.

The Wikipedia Site has an article on this…

http://en.wikipedia.org/wiki/Super_Hi-Vision

Super Hi-Vision (SHV), also known as Ultra High Definition (UHD), Ultra High Definition Video (UHDV), Ultra High Definition Television (UHDTV)[1], Extreme Definition Video and 8K is an experimental digital video format, currently proposed by NHK of Japan, the BBC, and RAI.

The new format has a resolution of 7680 × 4320 pixels, four times as wide and four times as high (for a total of 16 times the pixel resolution) as existing HDTV, which has a maximum resolution of 1920 × 1080 pixels. According to the Yomiuri Shimbun, the Japanese Ministry of Internal Affairs and Communications will be starting a public-private partnership to develop technology for SHV in the hopes of setting an international standard for Super Hi-Vision in addition to broadcasting with it beginning in 2020.[2]

So, it looks like the war isn’t over for higher definition. There will be an Ultra-High Definition format coming out … maybe in 10 or 15 years? Hopefully not sooner - a lot of people just had to replace their TV’s to get on HDTV.

Most of us probably didn’t realize it but this is what they also call 8K, but other higher resolutions are already being worked with called 2K and 4K … in Digital Cinema, see:

http://en.wikipedia.org/wiki/Digital_cinema

Digital cinema is distinct from high-definition television and in particular, is not dependent on using television or HDTV standards, aspect ratios, or frame rates. Digital projectors capable of 2K resolution began deploying in 2005, and since 2006, the pace has accelerated. (2K refers to images with 2048 horizontal pixel resolution.) (4K refers to 4096×2160 resolution.)

As of 2007 the most common acquisition medium for digitally projected features is 35 mm film scanned and processed at 2K (2048×1080) or 4K (4096×2160) resolution via digital intermediate. Most digital features to date have been shot at 1920×1080 HD resolution using cameras such as the Sony CineAlta, Panavision Genesis or Thomson Viper. New cameras such as the Arriflex D-20 can capture 2K resolution images, and the Red Digital Cinema Camera Company’s Red One can record 4K redcode *RAW. The marketshare of 2K projection in digital cinemas is over 98%. Currently in development are other cameras capable of recording 4K RAW, such as Dalsa Corporation’s Origin, and cameras capable of recording 5K *RAW, such as the RED EPIC, and cameras capable of recording 3K *RAW (for budget filmmakers) such as the RED SCARLET. (Raw redcode is a proprietary wavelet compression scheme offered on the redone camera. It can be defined further on user sites such at reduser, but is not by definition RAW, and does potentially contain compression artifacts.)

(that’s all for now. More at those links…)
