The Virtual Device – an Application Example

3The Virtual Device – an Application Example

The following sections define the general guidelines for building a Virtual Device.

3.1 System Overview

	Sources		• Satellite TV set top box (video and audio on an HDMI output)
			• DVD player (video on a CV output with analog stereo audio)
			• PC or laptop (PC Graphics on a 15-pin HD output with analog stereo
			audio)

	A Display Device		Flat panel LCD

	A Master RC		SV-552SummitView™ Processor Switcher

All the sources transmit video and audio to the SV-552(using Kramer SV-30Xwall plates) which outputs the video signals to the flat panel LCD and the amplified audio to a pair of ceiling speakers.

In this setup example, an iPhone® or an Android running cell phone is used as a user interface that will trigger switching. The audio and room control function is configured in the SV-552(see Figure 1).
