2-Channel HDMI® 4K60 4:4:4 HDR Scaling Output Card for DM® Switchers

A modular output card for card-based Crestron® DigitalMedia™ switchers. Provides two independent 4K HDMI® outputs with complementary analog audio outputs. Supports 4K60 4:4:4 and HDR video signals and provides built-in scaling.

The DMC-4KZ-HDO is an output card designed for use with card-based Crestron® DigitalMedia™ switchers (for example, the DM-MD8X8-CPU3). The card provides two independent HDMI® outputs with complementary analog stereo audio outputs. The HDMI outputs handle Full HD 1080p, Ultra HD, 2K, and 4K video signals with support for HDCP 2.2, HDR10, Deep Color, and high-bitrate 7.1 audio. Built-in 4K604:4:4 scaling enables devices connected to the HDMI outputs to handle any video resolution from NTSC 480i to DCI 4K. DVI signals are also supported using an appropriate adapter or interface cable.[1]

4K60 4:4:4 and HDR Support

The DMC-4KZ-HDO incorporates DM 4KZ technology, which uses VESA® Display Stream Compression (DSC) to handle the extreme bandwidth requirement of resolutions beyond 4K30 4:4:4 and 4K60 4:2:0. DSC is a lightweight, line-based 2:1 compression standard that delivers visually lossless performance for 4K60 4:4:4 and HDR signals.[2] DSC is applied to 4K60 4:4:4 and HDR input signals only. All other signals are transported uncompressed.

An existing 4K DigitalMedia system can be upgraded to handle 4K60 4:4:4 and HDR video with the installation of DM 4KZ cards, transmitters, and receivers. The upgrade can be accomplished without the need to replace wiring or switchers. The DMC-4KZ-HDO can replace a DMC-4K-HDO output card in an existing installation (additional programming may be required).

4K60 4:4:4 Scaler

An independent, high-performance 4K60 4:4:4 scaler is provided for 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, any video or computer source can be viewed simultaneously on multiple disparate displays, scaling the signal up or down to match the native resolution of each display.

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 EDID (Extended Display Identification Data) to configure each scaler.

Video Wall Processing

The DMC-4KZ-HDO provides zoom capability and bezel compensation on each HDMI output to display only a portion of the source image. Multiple DMC-4KZ-HDO cards can be combined to provide processing for a video wall composed of up to 64 individual displays. Video wall configurations up to 8 wide by 8 high are supported using a separate output for each display and one or more DM switchers.

Audio De-embedding

Each HDMI output on the DMC-4KZ-HDO is accompanied by a balanced/unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital stream and fed to a sound system.[3] The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.

CEC Embedded Device Control

When connected to a control system via a DM switcher, the DMC-4KZ-HDO provides a gateway for controlling display devices through CEC (Consumer Electronics Control) over the HDMI outputs, potentially eliminating the need for dedicated control wires or IR emitters.

To configure a DM switcher with input cards, output cards, cables, and other peripherals, use the online DigitalMedia Switcher Configuration Tool.

Are you upgrading an existing DM switcher that has multi-gang DMCO Series output cards? Use the online Output Card Additions and Upgrades Tool to update your existing output cards and switcher to the single-gang output card format.
