Delta Video Format Converters & Distribution Amplifiers...
With the growing mix of RGB and color difference video formats, there is a big need to convert signals from one format to another. Cameras, monitors, computers, character generators and large screen projectors use the red, green and blue (RGB) component video format. Betacam, MII VTRs, and most component video production switchers use YUV (also known as Y/R-Y/B-Y). Our Delta Series format converters are the ideal bridge between these formats.

Delta uses a modular design. Plug-in format conversion modules and rack-mounting frames need to be ordered separately. The easy to install frames are shipped with the selected modules already in place.


Delta Series Frames
Two Delta frames are available to meet your needs. The 1RU high frame accepts one or two modules. Each input is looping, and for each output there are three individual feeds. We also offer a 3RU frame that accepts up to ten modules. This frame has terminating inputs and two feeds per output.


Delta Series Modules
The Delta CB converts from RGB to YUV. In addition to the RGB-to-YUV transform, the Delta CB includes circuits to add sync and setup to the output of the Y channel. Sync comes from either sync-on-green or the external sync input.

The Delta BC Converts YUV to RGB plus Sync. The Delta BC obtains sync from the Y channel input and provides a separate sync output. Both models are calibrated to one of four signal level standards, depending on the region of the world and the component video signal specified. Formats include NTSC/Betacam, NTSC/MII, PAL/Betacam, and SMPTE/EBU N-10 & PAL MII standards. The Delta 33 is a three-channel video DA compatible with the two Delta frames.

The Delta 33 has a wide bandwidth to handle analog HDTV (40 MHz) and most wideband RGB video from graphics workstations. The 502007 consists of three separate high performance distribution amplifiers on one module. Each amplifier is based on a 120MHz amplifier with a 500 milliamp current boost output stage. Each amplifier has an easy to reach 15 turn front edge gain control and output signal test point. Each amplifier has three rear panel outputs (nine total for the module).
