Description
Extron’s YCS Transcoder is both a composite video to S-video
(luminance (Y) and chrominance (C)) decoder and an S-video to
composite video encoder. The inputs also have buffered loopouts. The
transcoder can convert either NTSC 3.58 or PAL video. A 3-line adaptive
comb filter performs the Y/C separation, virtually eliminating chroma
noise.
The decoder function separates composite video to Y and C signals for
an S-video output. The composite video input is also buffered with a
loopout. A DIP switch defines the standard of the composite video
input as either NTSC 3.58 or PAL.
The encoder function encodes S-video to a composite video output. The
S-video input is also buffered with a loopout.
All composite inputs and outputs are on BNC connectors. All S-video
inputs and outputs are on 4-pin mini-DIN connectors.
The rack-mountable transcoder has an external power supply and is
available in a world version.
Installation
For optional rack mounting, mount up to four YCS Transcoders on a 19"
1U Universal Rack Shelf (Extron P/N 60-190-01) (figure 1).

Figure 1 — Rack mounting the YCS Transcoder
1. Mount the YCS Transcoder on the rack shelf, using two 4-40 x 3/
16 screws in opposite (diagonal) corners to secure the case to the
shelf.
2. If necessary, mount the half-rack false front panel and/or the
quarter-rack false front panel (included with the Universal Rack
Shelf) alongside the transcoder, using two 4-40 x 3/16 screws in
the front holes for each panel.
Rear Panel Connections
1. Connect the input and output devices to the YCS Transcoder using
the typical transcoder application diagram (figure 2) as a guide.
