VGA/Video Input Card for DM Switchers

The DMC-VGA is an input card for a Crestron® DigitalMedia™ Switcher, providing one analog RGB video input[1] with stereo analog audio. The DMC-VGA handles computer resolutions up to WUXGA 1920 x 1200, as well as standard and HD video up to 1080p60. The professional balanced/unbalanced audio input accepts a stereo line level audio signal. Both the video and audio signals are converted to high-quality digital for distribution via DigitalMedia.

The DMC-VGA employs advanced analog video processing with anti-alias filtering and 3D comb filtering, offering improved performance over the DMC-DVI and other analog video input cards. Built-in time base correction is also included to ensure optimal results for use with video tape players.

In addition to the video and audio inputs, the DMC-VGA also includes an HDMI® output and a USB HID device port. The HDMI output can be used to pass the input signals through to a local audio processor or video monitor, or to feed a second DM® switcher for output expansion purposes. The USB HID port connects to the local source device (i.e., computer or media server), allowing it to be controlled by a mouse or keyboard located in another room, or at a presentation lectern, conference table, or some other remote location.

The DMC-VGA may also be used with the DMCI DigitalMedia Card Interface to create a very handy problem-solving tool with many useful functions. For instance, it can be used to convert analog video and audio to digital and merge them into a single HDMI output. As part of a complete Crestron control system, it can be used to detect input source format information, manage EDID, and extend a USB HID mouse/keyboard signal over Ethernet.

Whether installed in a DM switcher or DMCI, the DMC-VGA card affords a digital upgrade for analog-based systems like Crestron MPS, QuickMedia®, and the CEN-RGBHV Series. A simple HD15 VGA cable and balanced stereo audio cable connected between the output of an MPS system and the input of the DMC-VGA allows every RGB, component, S-Video, composite video, and audio input on the MPS to be converted to HDMI and DigitalMedia[1].
