Unprecedented Value in Digital Video Systems Support
The V-SG4K-HDI is a compact, portable, and economical digital test generator that's a perfect choice for video engineers, system integrators/installers, shooters and product designers. It is feature-rich and easy to use. This unit is capable of generating nearly any combination of display resolutions, sampling and frame rates in the digital spectrum, along with an amazing array of audio combinations.
Equipped with complete EDID interface software, the V-SG4K-HDI quickly resolves problematic interconnection issues and is capable of emulating any device to which it is connected. The V-SG4K-HDI comes complete with a Windows® compatible computer application that provides the option of rapid remote control operations and operates equally well with the on-board push button panel.
3G InterfaceHDSDI is easily facilitated using the MXL VAC-12HS converter.
Power OptionsBattery operation is a breeze with Marshall's highly flexible battery adapter accessories using any 5 to 7VDC combination. The V-SG4K-HDI can also be powered from any USB related device, including mobile phone chargers.
Marshall's test generator allows easy field calibration, testing and maintenance of many applications such as: production line quality assessment; studio equipment for both installers and users; television sets by TV engineers or technicians; digital signage configurations with extenders, switches, splitters or video wall processors; and discerning home theater users. Using the corresponding video cable needed, simply connect the video test pattern generator to the supported display unit to run the test patterns on the screen. No other video source, such as a computer, DVD player or set-top box is needed for the testing process.

Color bars are an artificial electronic signal generated by the camera or by post production equipment. They are recorded at the head of a videotape to provide a consistent reference in post production. They are also used for matching the output of two cameras in a multi-camera shoot and to set up a video monitor.
Before we proceed, you should know that computer monitors are quite different from video monitors and TV sets. You are seeing this on a computer monitor so you will not have the same kind of controls or images as on a video monitor. In fact, if you create graphics on a computer monitor, it's very easy to be fooled into thinking you have a great looking graphic for your video. But the only real test is when you see that image on a properly adjust video monitor.
