Composite and S-Video inputs automatically select between NTSC, PAL and SECAM formats.
Component/RGB and DVI-D inputs accept SD, ED and/or HD video at either 50 or 59.94 Hertz.
HDCP encryption is supported for DVI-D inputs. If encrypted, DVI-D inputs are decrypted,
processed, scaled and then re-encrypted for output as DVI-D (as opposed to being simply
“passed through”). The digitized data is then decoded into a digital video format for further
processing. For analog outputs, video is over-sampled to provide the best possible image
quality.
As part of the scaling process, digital filtering is used to enhance the image detail. This
enhancement allows standard definition inputs, such as DVDs, to appear to be much higher
resolution, even when viewed on the large screen sizes common in home theaters.
When the digital processing is completed, video is converted to analog using
digital-to-analog converters (DACs), or is output as DVI-D (digital) video. DVI-D video can use
either the “PC” range (full range black to white), or “video range” (reduced range for black to
white to allow for blacker-than-black and whiter-than-white levels).
An infrared (IR) remote control, or the serial RS232 port, is used for control and software
update. Critical display setup parameters have direct commands. Other functions use an
on-screen menu.
To allow options such as ISF day/night specific modes, the DVI-D and analog HD inputs
(Inputs 1 through 4) have four independent configuration memories. The other inputs have
two independent configuration memories.
HDCP encrypted DVI-D sources must be re-encrypted for output. As a
result, the analog RGB output is disabled when a DVI input is selected.
Also, the display must support HDCP to show these encrypted sources. If
the video input is interlaced, it is first deinterlaced into a progressive
format.
