HDMI
This input provides the facility to integrate the excellent quality of a
digital image with a multichannel audio signal.
In fact the High Definition Multimedia Interface (HDMI™) combines
the uncompressed high definition video signal with a multichannel
audio signal.
In addition, the interface enables control data to be exchanged
between the video source and the HT system in order to optimise
the displayed picture.
The HDMI™ input makes it possible to connect to video sources that
use the High-Bandwidth Digital Content Protection protocol (HDCP)
to protect their contents. This is possible because the HDCP protocol
forms part of the definition of HDMI™ technology.
Connecting an audio-video source to the HDMI™ input makes it
possible to take the audio signal from the S/PDIF digital optical
output (TOSLINK female connector).
CONTROL (RS232)
The system can be controlled via a personal computer or home
automation systems by means of the serial port: simply connect
a serial cable from an RS232 serial port to this input. On request,
SIM2 will send you a document containing serial port settings and
a list of the main commands.
USB
The USB port can be used as an alternative to the RS232 serial
port to control the system from a PC or home automation device.
Ask SIM2 for the drivers to install on your PC and documentation
concerning the device control commands.
S-VIDEO
This input can be used to connect equipment fitted with an S-Video
output by means of a cable with a mini-DIN connector. Typically,
the corresponding output on the source can be identified by the
wording S-VIDEO or Y/C.
The S-VIDEO signal output is available on numerous video sources
(DVD players, video recorders, video cameras, still cameras, etc.).
This signal is preferable to Composite Video because it gives better
picture quality.
RGB / YCrCb
The RGB/YCrCb inputs are composed of two groups of four RCA con-
nectors each. The two sets of inputs are equivalent to each other.
Both inputs are able to acquire the following video signals:
- RGB with composite sync on the green signal (RGsB);
- YCrCb “component”, with composite sync on the luminance signal
(YsCrCb);
- RGB with separate composite syncs on a fourth cable to connect
to the C-SYNC input;
- YCrCb with separate composite syncs on a fourth cable to connect
to the C-SYNC input;
The video signals that can be connected to these inputs can
have horizontal scanning frequencies of 15 kHz (standard video
resolution) or 32 kHz (progressive scanning video, high definition
video).
By using a suitable SCART to RCA connector adapter cable, an RGB
video signal from a source equipped with an SCART connector can
be connected to this input.
RGB GRAPHICS
This input should be connected to an RGB-type video or graphic
signal using a cable with a DB15HD type connector.
The signal source device (typically a personal computer or game
console) must be able to provide separate H/V synchronisation or
composite H+V synchronisation.
The video or graphic signals that can be connected to this input
can have horizontal scan frequencies (H-sync) of between 32 and
80 kHz and a vertical frequency (V-sync) of between 48 and 100
Hz. Image resolution can vary between 640x480 and 1600x1200
pixels (VGA, SVGA, XGA, SXGA, UXGA).
