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. Only one point in the colour measurement 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. It has to remain uniform across different luminance levels. In the 810, the flat field uniformity is superbly aligned for virtually zero deviation for an extraordinarily wide range of luminance values.

The fundamental intention behind the Meridian 810 Reference Video System is to give you, the viewer, the impression of looking through a window into the cinematographer’s world, with all its detail and three- dimensionality: and calibration is an important part of achieving that goal.

If you forget that you are looking at a screen illuminated by a complex chain of art and technology, and instead are connected directly to the film-maker’s visual imagination, then – and only then – have we truly succeeded. And this is exactly what you

will experience with the 810. At last, the cinematographer’s dream is realised.

810 Scaler completes the system

To display an image with a resolution of

10 megapixels requires some very special scaling. To meet this requirement, Meridian has developed the 810 Reference Video Scaler.

Where some scaling technologies still rely on copying adjacent pixels to handle upconversion, the 810 scaler is fully interpolative, and offers a significantly higher level of processing. A brand new design, featuring Marvell’s powerful Qdeo® processing technology, the scaler converts any digital source (480i to 1080p) up to full 10 megapixel resolution. Its quiet and natural video processing produces images that

are free from noise and devoid of artefacts whether operating in 4:3, 16:9 or 2.35:1 modes.
