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.
