  • @fix renderers don't work the way you're describing, or only do if you're using a very bad renderer or relying on low-resolution textures to define your surfaces. Folks rendering with something like Renderman have always been rendering sub-pixel detail and shading under even the most nominal settings. That's the beauty of the micropolygon, REYES style renderer (like Pixar's PRman and SESI's Mantra).

    Plus, assuming a lower threshold of, say, only 3x3 oversampling, even a crude, brute-force renderer is generally doing 6K renders and filtering down for 2K final images and why CGI always has to even then be blurred to fit in with a digital scan, because the CGI image represents a more true "2K" image than a 2K film scan or CCD frame, because they're not sampling in the same way. Nyquist, and all that jazz. This is also why the GH2 is able to achieve higher sharpness and detail than a Canon that line-skips, for instance.

    Anyway, good quality renderers, like Renderman, aren't interpolating. Its shading is resolution independent and shaders that aren't limited to bit-mapped 2D textures are as well.

    Panasonic 4K prototype at CES

  • Sony shows a fake prototype 4K prosumer camera so a day later Panasonic has to show a fake prototype too. Most important but not explained is what 4K will be compressed at and with what codec.

  • Rey Roque, Westinghouse Digital’s marketing senior VP, said that just as the company brought high-resolution value to the first 1080p HD sets, it is now poised to bring value to Ultra HD.

    Unlike the currently available $20,000-plus 84-inch Ultra HD sets from LG and Sony, Westinghouse is going to offer its sets starting in the first quarter at the bargain suggested retail prices of $2,499 for the 50-inch set, $3,000 for the 55-inch set and $3,995 for the 65-inch set


    My understanding is that they are made by Chinese manufacturers with their own panels.

  • finshed a real 4k (3840x2160) streaming demo, made with stage3d, multithreading and stageVideo in flash. impossible in html5. for streaming container i wrap all in HLS and use our mpegTS decoder, also in flash. no streaming server required and 40% less cpu load then youtube. for mobile fallback i use an 720p hls stream with 1.5 mbit. the 4k, believe it or not, uses only 3.5mbit/sec. only had time to test it with big ATI and nvidia gfx cards. cant wait to get red 4kplayer and sdk in my hands :)

  • BBC makes wildlife series in 4k!

    Survival will feature meerkats and other wild animals in 4K video, which will give the programmes a more “cinematic” look, The Independent has reported.

    But viewers will need a new television to watch the series in 4K – and the sets have only just begun to be sold in Britain.

  • Innolux has plans to release 28-inch LCD Ultra HD (3840 by 2160) monitor panels in 2013, according to company president JC Wang.

    Wang also confirmed that industry rumors regarding Innolux producing 42-inch Ultra HD TV panels are true, and that the company has been shipping 39-, 50-, 58- and 65-inch Ultra HD TV panels since March

  • Taiwan-based panel makers' low-cost 50-inch Ultra HD TV panels are expected to drop in pricing from US$540 to US$510 in June 2013, according to industry sources.

    The drop in pricing means that TV vendors are likely to further drop pricing for Ultra HD units, and that the gap between Full HD and Ultra HD TV prices will further close. At present, mid-range 50-inch Full HD TV panels are priced at US$340 while high-end ones of the same size are priced at US$369. Ultra HD TVs sized 50-inch meanwhile are priced at around CNY$8,500 (US$1,385) in the China market.


  • China-based TV vendors are becoming increasingly interested in selling Ultra HD products and are reportedly selling the technology for only about 20-50% higher in price compared to their Full HD units, according to market observers.

    Some of the vendors include TCL, Skyworth and Haier, which are dropping prices to as low as 1.2 times (20%) the amount of their Full HD units amid decreasing prices for Ultra HD TV panels, the observers said.

    The observers said this is in stark contrast to international vendors that are selling Ultra HD units for about 2-3 times the price of their Full HD units.


    And this is just firms using business opportunity.

  • 4K phone is coming soon


    The Honami brings a new UI, new app drawer and a new launcher. There is even a new Walkman app with unlimited music streaming available.

    The build.prop also reveals some of the specs on the phone such as the 20MP camera and the 4000 x 2000 resolution (4K) that video is recorded in. There also appear to be a number of Augmented Reality modes that can be activated through the camera.

    There is some speculation that the Sony i1 Honami will be introduced during a Sony event in Paris on July 4th.

  • Panasonic AVC-Ultra updated with 4K support, up to 444 12bpp, hardware comes in 2014.

  • Sharp Corporation will introduce into the Japanese market a new 32-inch-class LCD monitor, the PN-K322B. This professional-use monitor features an originally developed high-sensitivity, high-precision touchscreen and delivers 4K resolution (3,840 × 2,160 pixels)-a level of resolution four times that of full HD.

    The PN-K322B is Sharp's latest ultra-high-definition display. Its high-precision touchscreen allows accurate onscreen handwriting of fine text and lines, with writing performed via a dedicated touch pen with a pen-tip width of just 2 mm. The display also supports multi-touch operation.

    Thanks to IGZO technology and an edge-lit LED backlight, the PN-K322B boasts a slender profile with a thickness of just 36 mm*2-the thinnest in its class. An included stand allows the monitor to slide easily between two angles depending on the application: vertical for viewing the monitor or low-angle for onscreen writing and touchscreen operation.

    The PN-K322B features a palm cancellation function that prioritizes pen input even when the user's hand is resting on the touchscreen. Input connectors on the PN-K322B are compatible with the latest DisplayPort™ and HDMI™ interface specifications, enabling the monitor to display*3 4K ultra-HD content delivered from a PC via a single-cable connection.

    Date of introduction in Japan July 30, 2013, Monthly production 250 units

  • I found this article on nofilmschool to be interesting, it basically talks about how 4k is more valuable than just the "extra resolution" but also the color space and so on...

  • @GravitateMediaGroup

    It is repost (written with own words) of some weird article. Do not remember it,

    Larger color space is not related to resolution (they only mention some standard). In fact, with going into cheap LED backlights from tubes backlights most TVs lost some unifirmity and some gamut.

    I am not even started to talk about mobile devices where gamut and battery life are always two opposites (for LCD screens, for OLED it is not so).

  • Asus 4K monitor review

    Even coming into the office right after a standard 30”, 2560x1600 display, the difference is huge. You get either a larger desktop, or a far crisper screen, or possibly both. It isn’t a small difference, but one that I can notice easily, and every single time I sit down to my desk. It also is apparent that many application vendors have to hurry up with their software support for DPI scaling, because when it isn’t supported correctly it is really ugly out there.

    In the end, my feelings about the ASUS PQ321Q wind up being very simple. Of the dozens of displays that I’ve reviewed for AnandTech so far, this is the one I want to hold onto the most. The razor sharp screen is just addictive to use, and you realize this is the future for displays. I’m sure over the next few years that performance will improve, prices will come down, and features will increase, and that helps everyone. But I want this now, and I don’t want it to leave my house.
