The DMC-SDI is an input card designed for use with any card-based Crestron®DigitalMedia™ Switcher. It provides one SDI input, with complementary SDI loop-through, HDMI® pass-through, and analog audio outputs. The SDI input supports SD-SDI, HD-SDI and 3G-SDI formats, handling high-definition video signals up to 1080p60 and 2 channels of 24-bit digital audio [1] through a single coaxial cable.
3G-SDI
Support for 3G-SDI enables DigitalMedia to accommodate signals from many high-end professional cameras, broadcast switchers, and other AV equipment. An SDI loop-through output is included for connection to a local monitor or other SDI device.
HDMI® Pass-Through
Every DM® switcher input card includes an HDMI output port, which can be used to pass the video and audio input signals through to a local audio processor or video monitor, or to feed a second DM switcher for output expansion purposes.
Audio Extracting
The DMC-SDI also includes an unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital input and fed to a sound system or multiroom audio distribution system. The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.[1]
Standalone SDI to HDMI Converter
In addition to its use as an input card for DM switchers, the DMC-SDI may also be used with the DMCI DigitalMedia Card Interface [2] to create a very handy problem-solving tool. It can be used to convert SDI video and audio to HDMI, or to extract an analog audio signal from an SDI source.
