4-3. COMPOSITE INPUTS (9 to 16) & S.VIDEO INPUTS (S1 to S4):
The Composite Video signal, usually called COMPOSITE or VIDEO, is available on most video equipment (VCR, DVD,
CAMCORDER…), but is also the lowest in picture quality. The video standard of this signal can be NTSC, PAL or
SECAM. The signal is transmitted on a single coaxial cable, and is connected to the video equipment with an RCA or a
BNC connector.
The S.VIDEO signal, also called Y/C, HI-8
™ , or S.VHS ™ , is available on DVD players and high quality VCRs (S.VHS).
The S.VIDEO signal in which the Luminance (Y) and Chrominance (C) informations are separately transmitted (2 wires)
gives a higher quality picture than the Composite video signal. The S.VIDEO connector is usually a 4 pin Mini-DIN
connector also called Oshiden
™ connector. It can also sometimes be on 2 BNC connectors.
4-4. MAIN AND PREVIEW OUTPUTS
The GRAPHIC SWITCHER II ™ is equipped with 1 MAIN OUTPUT on BNC (x5) connectors for the DISPLAY DEVICE,
and two monitoring outputs on HD 15 connectors.
4-5. OPTIONAL VIDEO OUTPUT (OPT-GSW2-VO option)
The GRAPHIC SWITCHER II ™ equipped with this option provides simultaneously 3 video signals (composite video,
S.VIDEO and YUV) in output. These 3 video outputs display the same image as the MAIN output. Therefore you can
record your presentation onto one or many video recorders of your choice.
