Overview

This article explains how composite analog video is supported by NI Video Measurement Suite (VMS) and the legacy VideoMASTER Analyzer. It also explains which composite analog video standards are supported.

1. Introduction

VMS and VideoMASTER Analyzer support composite analog video formats. Composite video signals carry all of the synchronization, chrominance, and luminance information on a single signal. The composite signal is also referred to as CVBS (color, video, blanking, and sync) or sometimes CCVS (composite color video signal).

The NTSC and PAL composite video color encoding standards are all supported. The SECAM color encoding standard is not supported in NI VMS/VideoMASTER, but it is supported by the NI Analog Video Generator. For more information on VMS support for the composite video format, please review the Fundamentals»Supported Video Signals»Composite Video Signals (CVBS) section of the NI Video Measurement Suite Help.

You can acquire composite video with VMS or VideoMASTER directly with a supported digitizer like the NI 5122/5124 (up to two composite channels) or through the NI BNC-2178 VideoMUX (up to 16 composite video channels). After configuring your acquisition hardware, you can select the video standard to acquire as shown in Figure 1.
