Introduction

About the SVS 100

Extron’s SVS 100 Seamless Video Switcher is a four-input, one output switcher that provides low-cost seamless switching for applications such as video conferencing, distance learning, staging and video editing, without the need for expensive genlock equipment. The switcher inputs can be NTSC or PAL. The SVS 100 seamlessly switches among the inputs using digital switching effects, such as cuts, wipes, dissolves, and fades. These special effects eliminate the need for expensive genlock equipment. If necessary, the SVS 100 can sync to an external black burst signal for broadcast applications.

The switcher can accept inputs from up to four video sources, such as VCRs, DVD players, laser disk players, CODECs, and document cameras (see figure 1-1). Two of the inputs autoselect between S-video or composite video, with S-video as the priority. The remaining two inputs are composite only. Each input is buffered and output on an adjacent connector.

S-video inputs are encoded to composite, and composite video inputs are decoded to S-video. Three NTSC or PAL video outputs (two composite and one S-video) allow multiple displays of the switched video signal without the need for a distribution amplifier.

Balanced Input

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, commanded via the Windows-based control program or under RS-232/RS-422 control, allows the user to select from any one of the four audio input sources. See to chapter 5, Serial Communication, for details.

Genlock connections

A genlock device (black burst generator) can be connected to the SVS 100 via the BNC connectors shown below. The genlock feature allows the SVS 100 to be synchronized with other system components for seamless vertical interval switching between sources. See Genlock and Vertical Interval Switching in this chapter .

Figure 2-6 — Control device and external sync connections

Genlock In connector — Connect an external black burst signal to this BNC

connection for genlocking the video signal in broadcast or other sync-critical applications.

Genlock Out connector — Connect any downstream equipment that

requires genlocking to this BNC connector to route the black burst signal throughout the system in broadcast or other sync-critical applications.

RS-232/RS-422 connection

RS-232/RS-422 port — Connect a host device, such as a computer or touch

panel control, to the SVS 100 via this 9-pin D connector for serial RS-232/RS-422 control. See chapter 5, Serial Communication, for details on how to install and use the control software and the SIS commands.

The SVS 100 comes from the factory already configured for RS-232. To set the SVS 100 for RS-422 operation, please see “Configuring the SVS 100 for RS-422” in the Appendix.

Genlock and Vertical Interval Switching

For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and also passed to another device via the Genlock Out connector.
