This article discusses the component analog video (CAV) formats supported by NI Video Measurement Suite (VMS) and the legacy VideoMASTER Analyzer.

1. Introduction

VMS and VideoMASTER Analyzer support the component analog video (CAV) format. Component analog video signals are comprised of three separate channels, each carrying a different color component. The following component analog video specifications are supported:

  • RGB color space, including RGsB (sync on green), RGB+S (separate sync), and RGB+HV (separate H- and V-sync pulses)
  • YUV color space (sometimes referred to as YPbPr), including YsUV/YsPbPr (sync on Y), YUV+S (separate sync), and YUV+HV(separate H- and V-sync pulses)
  • Both 16:9 and 4:3 aspect ratios
  • Progressive, progressive segmented frame, and interlaced scan modes
  • SDTV, EDTV, and HDTV standards with resolutions from 480i to 1080p

For more information on VMS support for the component video format, please review the Fundamentals»Supported Video Signals»Component Video Signals (CAV) section of the NI Video Measurement Suite Help.

Note: You can only acquire component video with NI VMS or VideoMASTER through the NI BNC-2178 VideoMUX, which supports up to four component channels.

After you have configured your hardware using the process described in the NI Video Measurement Suite Help at Using NI VMS»Configuring Signal Acquisition»Configuring Acquisition for CAV Signals, you can view the supported component analog video resolutions as shown in Figure 1.

VMS 3.2.1 supports HDTV VGA, RGB+HV, and YUV+HV video signals at 720p or 1080p, but may require an external multiplexer and additional configuration to correctly detect the sync signals for these higher resolutions. See Acquire High-Resolution VGA Signals in NI Video Measurement Suite (VMS) for more information.

Note: The CAV format is not supported by the NI Analog Video Generator.
