What is the availability of the optional DV module?
To be determined at this time.
What does the DVI connector provide on an X75?
The DVI connector is an output for HDTV signals. The format is a single link DVI-D digital RGB
HDTV signal for modern video displays (e.g., Plasma, LCD)
What is DVI-D?
The connector used to connect VGA monitors to PCs is called an HD-15. This 15-pin connector is the
same size as a 9-pin. It carries an RGB signal — typically analog or possibly TTL levels. A new
connector that has emerged as a standard for computer displays is DVI.
DVI is the “Digital Visual Interface” which uses a flat panel connector scheme that incorporates
PanelLink’s TDMS (transition-minimized differential signaling) as its digital video signal, a regular
analog signal (RGB) and DDC (Display Data Channel) for Plug-n-Play compatibility. This means that
DVI can drive two monitors from one connector on the PC. There are a few different versions of the
DVI connector:
~ DVI-I supports both analog and digital video signals.
~ DVI-D supports only digital video signals.
~ DVI-V supports only analog video signals.
DVI connectors are not found on broadcast video CRT monitors today — however, you can find them
on plasma, some LCD, computer (LCD/CRT) monitors.
The
X75HD
supports DVI-D with digital HDTV signal outputs (1080i and 720p). Please note the
following points:
~ This implementation on the
X75
will be single channel.
~ The DVI-D output on the
X75HD
will be used to monitor HDTV coming out of the X75HD
using plasma monitors.
~ NEO SuiteView has a DVI-V input option that supports computer outputs (RGB), but it does
not support DVI-D.
~ For the case of monitoring the output of the
X75HD
using NEO SuiteView, the
X75HD
SDI-
HD coax output would be used.
What is the propagation delay through the noise reducer? Is there a median filter? Is there a diagonal filter?
There are two noise reducers available in the
X75
: an HDTV noise reducer and a SDTV noise
reducer. The HDTV noise reducer is included with every X75HD. Controls available for the HDTV
noise reducer are threshold range, image threshold range and image enhance. There is no additional
propagation delay when the HDTV noise reducer is used.
The SDTV noise reducer is a software key option. The SDTV noise reducer has 3-Dimensional
processing. There is impulse noise reduction, Gaussian random noise reduction, compression blocky-
ness and mosquito artifact reduction, and sharpening and softening of images. Particularly effective
for the reduction of satellite noise, the impulse noise reducer automatically detects impulse noise and
applies the median filter when necessary. The recursive 3D directional filter removes Gaussian noise
and compression artifacts, which include blocking artifacts and mosquito noise. The directional
softening/sharpening filter can be used in various applications.
For example, the softening filter can be used as compression pre-filter to reduce mosquito noise. The
sharpening filter can be used to enhance picture appearance. For MPEG pre-processing applications,
