Crestron DMC-4K-HDO 2-Channel 4K Scaling HDMI Output Card for DM Switchers

The DMC-4K-HDO is an output card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides two independent HDMI® outputs with complementary balanced analog stereo audio outputs. The HDMI outputs are each capable of handling Full HD 1080p, Ultra HD, 2K, and 4K video signals. Built-in 4K/60 scaling enables devices connected to either HDMI output to handle any video resolution from NTSC 480i to 4K DCI.[1] DVI signals are also supported using HDMI-to-DVI adapters or interface cables.[2]

4K Ultra HD: The DMC-4K-HDO is capable of handling video resolutions up to 4K and Ultra HD. Support for 4K video also ensures support for the latest generation of computers and monitors with native resolutions beyond 1080p and WUXGA.

4K/60 Scalers [1]: An independent, high-performance 4K scaler is provided at each output to ensure that input sources of any resolution or frame rate can be routed and displayed reliably on virtually any display device without compromising the original input signal. As part of a DM® switcher with many outputs, this allows any video or computer source to be viewed simultaneously on multiple disparate displays, scaling the signal up or down to match the native resolution of each display while simultaneously delivering a pure, unprocessed signal to any display with the same native resolution as the source.

No matter what source is selected, or where it’s routed, the DMC-4K-HDO helps to ensure an optimal image on every screen. It can take any input resolution from standard definition NTSC 480i to ultra high-definition 4K DCI, and scale it beautifully to any output resolution up to 4K DCI (4096 x 2160 @ 60 Hz [1]). Interlaced sources are converted to progressive scan using motion-adaptive deinterlacing. Intelligent frame rate conversion enables support for 24p and PAL format sources. Fully automatic operation eliminates any complicated setup by utilizing the displays’ EDID to configure each scaler.[4] (NOTE: [4] EDID (Extended Display Identification Data) is data embedded in an HDMI or DVI signal that enables a display device to tell the scaler what resolutions and formats it can support.)

Video Wall Processing [1]: The DMC-4K-HDO has another trick up its sleeve, providing zoom capability and bezel compensation on each output to display just a portion of the source image. Using this feature, up to 32 output cards may be combined to provide processing for a video wall composed of up to 64 individual displays. Video wall configurations up to eight wide by up to eight high are supported.

Audio Extracting: Each HDMI output on the DMC-4K-HDO is accompanied by a balanced analog audio output, allowing stereo audio signals to be extracted from the digital stream and fed to a sound system. The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.[3] (NOTE: [3] The analog stereo audio outputs are only active when the selected input source is outputting a 2-channel stereo signal. For applications using multichannel surround sound sources, the DM switcher should be equipped with “DSP” type input cards, which can downmix the surround sound signals to stereo.)

CEC Embedded Device Control: DigitalMedia offers an alternative to conventional RS-232 and IR display control by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to a control system (via the DM switcher), the DMC-4K-HDO provides a gateway for controlling display devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters.

Note:

[1] Passes 4K video at up to 60 Hz. Scaling and video wall processing are future features that will be enabled soon through a firmware update. When scaling is initially enabled, it will support 4K resolutions at frame rates up to 30 Hz. Support for 4K scaling at 50 and 60 Hz will be enabled in a later firmware update. [2] DVI is supported via either HDMI output using a suitable adapter or interface cable. CBL-HD-DVI interface cables are available separately.
