User manual MERIDIAN 810 BROCHURE

[. . . ] The 810 system comprises two primary elements: the Ultra High Definition 810 Reference Video Projector, an entirely new D-ILA-based digital projector offering a previously impossible 10 megapixels ­ exceeding the resolution even of commercial digital cinema projectors ­ and the 810 Reference Video Scaler, a special processor designed to optimise the imaging of HD and standard resolution inputs for the vast new possibilities offered by a 10 megapixel projection environment. The result is a system that, Meridian believes, represents the most realistic home theatre performance in the world. Using a brand new light engine, the Meridian 810 Reference Video Projector offers an effective resolution of 4096 x 2400 pixels, or 9, 830, 400 pixels. In comparison, a conventional HDTV image at 720p represents just one megapixel, while full-spec HD (1080p) is still only twice that. [. . . ] This is the method employed by the Society of Motion Picture and Television Engineers (SMPTE), and used throughout the film industry.

The purple and green rectangles (top left) indicate the resolution of a Standard Definition (SD) image ­ 720 pixels wide by 480 (NTSC) or 576 (PAL) high and generally interlaced. A 720p HDTV image is 1280 pixels wide by 720 high and progressive-scan, while a `full spec' HDTV image is 1920 x 1080 progressive (`1080p') ­ 1080i (interlaced) images are also common. A standard Digital Cinema specification, generally referred to as `2K', delivers 2048 x 1080 pixels progressive. The latest `4K2K' Digital Cinema spec is 4096 x 2160, delivering an 8-megapixel image. The 810 projector goes beyond this to deliver a 10-megapixel. 4096 x 2400 image. 810 Reference Video System 10-megapixel digital projector & scaler 810 Scaler Outline Technical Specification All information is subject to revision Supported formats ·Inputformats:RGB480i, 576i, 720p, 1080i, 1080p;24/48/50/60f/s ·Colourformats:RGB, YCbCr444, and YCbCr422. ·Outputformats:upto4096x2400to drive projector inputs Processor technology ·MultipleMarvellQdeovideoprocessors under microprocessor control Connections ·HDMIIn ·DVIin ·QuadDVIOut ·RS232Projectorsocket ·RS232Controlsocket ·MaintenanceRS232socketforfirmware upgrades ·USBportforfirmwareupgradesvia memory stick ·MeridianCommsBNC ·Ethernetport(RJ45)allowsaccessto inbuilt web server for configuration ·IRsensorportforconnectionofG12 remote sensor ·Triggeroutputx3:onecontrols anamorphic lens slide; others user configurable it will be used. The installation contractor provides Meridian with full details of the operating environment including the specifications and colour of the screen (the 810 will support both grey and white screens, though the latter is recommended), as the reflected light level depends on several factors, including the throw length and the gain of the screen, as well as the light brightness. The 810 light output is controlled as part of a calibration process that meets international cinema standards every step of the way. The calibration of the 810 projector is therefore part of an integrated installation and configuration process, including every aspect of the home cinema environment. Calibration is often a multi-dimensional process. For example, a conventional setup approach simply aligns a projector's white reference to a given colour temperature. But colour temperature alone does not tell you how accurate the colour rendering is. Onlyonepointinthecolourmeasurement coordinate system (D65) is actually correct ­ and our projectors are calibrated specifically to that point. The optimisation process provides both accurate colour temperature and Gamma tracking. Similarly, it is not enough just to set up a projector to give a uniformly white screen at full output. [. . . ] Per-pixel noise and compression artefact reduction removes noise typically inherent in digital video, while per-pixel motion-adaptive 3-D de-interlacing removes jaggies and eliminates feathering. Marvell's Adaptive Contrast Enhancement (ACE) and Intelligent Color Remapping (ICR) render rich and vivid images, optimising texture, detail, edges, contrast and colour, providing a consistent, immersive viewing experience for all types of content. Projector and scaler are operated as a single system. Serial data commands flow between the two units to select the appropriate projection and image processing parameters at both ends of the chain, so that the image will always be at its best, whether it is receiving it from DVD, HDTV, Blu-ray Disc or alternative sources.
