YCS SW2 • Introduction

1-31-2

Digital time base correction — Time base correction stabilizes

the video signal in the time domain. This results in a

signiﬁ cantly more stable image on the screen and better

recording quality from input sources with unstable video

signals, such as consumer VCRs and worn or multi-

generation VHS tapes.

Simultaneous composite video and S-video outputs — One

composite video and two S-video outputs allow for

recording and display at the same time.

Individually buffered S-video outputs — Two individually

buffered S-video outputs are provided on one female

4-pin mini DIN connector and a pair of female BNC

connectors, for easy integration.

Contact closure remote control — Inputs can be selected

remotely using a user-supplied two-button contact closure

device.

Quad standard compatibility — The digital quad standard

decoder/encoder provides for universal compatibility.

Enclosure — The YCS SW2 has a compact 1U high, ¼-rack

wide, 3 inches deep Versatools

metal enclosure that can

be easily placed or mounted in a variety of locations.

Power supply — An external 12 VDC power supply with a

two-pin captive screw connector accepts 100 to 240 VAC.

Rack and furniture mounting — The YCS SW2 can be mounted

on a rack shelf, under a desk or podium, or on a projector

pole, with an optional mounting kit.

About this Manual

This manual contains information about the Extron YCS SW2

Switcher, and discusses how to install, conﬁ gure, and operate it.

The terms “YCS SW2,” “YCS,” and “Switcher” are used

interchangeably throughout this manual.

About the YCS SW2

The Extron YCS SW2 is a high-performance, two input

(one composite video and one S-video) switcher with three

simultaneous outputs (one composite video and two S-video),

digital transcoding and autoswitching capabilities, and digital

time base correction (TBC). Using a 3-line NTSC/5-line PAL

digital comb ﬁ lter, the YCS accepts NTSC 3.58, NTSC 4.43, PAL,

or SECAM composite video, and decodes the signal into Y

(luma) and C (chroma) for S-video. As an encoder, it combines

Y and C signals and outputs a composite video image.

Certain projectors have both video and S-video inputs, but

can use only one of them at a time. The YCS SW2 solves this

problem by autoswitching between composite video and

S-video, then decoding the S-video to feed to the projector. (See

ﬁ gure 1-1 under Application Diagrams, later in this chapter.)

The YCS SW2 can also be used at the output of a multi-format

switcher, such as the Extron MPS 112, to automatically select

between the video and S-video group outputs, sending a single

S-video signal to the projector. (See ﬁ gure 1-2.)

Inputs can be selected by pressing the front panel buttons, by

enabling autoswitching using a jumper wire, or by contact

closure using a remote push-button device.

Features

Autoswitching — The YCS SW2 can be conﬁ gured to

automatically switch to the active input when the

YCS detects a video signal, thus providing hands-free

switching. If both the composite video and the S-video

signals are present, the switcher defaults to input 2,

S-video.

Digital encoding and decoding — The YCS SW2 digitally

decodes (separates) the composite video input signal into

Y and C for S-video, and encodes (combines) the Y and C

signals of S-video input into composite video.
