HDMI® Input Card for DM® Switchers
Provides a single HDMI® input for any DigitalMedia Switcher with modular input card slots.
For a replacement, please see DMC-4K-HD.
The DMC-HD is an input card designed for use with any card-based Crestron® DigitalMedia Switcher. It provides one HDMI® input, with associated HDMI pass-through and analog audio outputs. A USB HID port is also provided. The HDMI input handles Full HD 1080p video signals with support for HDCP, Deep Color, 3D, and high-bitrate 7.1 audio, as well as computer signals up to WUXGA. The HDMI input can also handle DVI and DisplayPort Multimode signals using an appropriate adapter or interface cable.
Every DM switcher input card includes an HDMI output port, which can be used to pass the input signal through to a local audio processor or video monitor, or to feed a second DM switcher for output expansion purposes.
The DMC-HD also includes an unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital input and fed to a multiroom audio distribution system. The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.
NOTE: For applications requiring the simultaneous distribution of multichannel surround sound and 2-channel stereo audio signals, use model DMC-HD-DSP.
Built-in USB HID signal routing allows a connected computer (or other USB HID-compliant host) to be controlled by a mouse and/or keyboard located at a presentation lectern, conference table, or some other remote location. Expanded USB signal routing capability is available using Crestron USB over Ethernet Extenders.
CEC Embedded Device Control
DigitalMedia offers an alternative to conventional IR and RS-232 device control by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to a Crestron control system (via the DM switcher), the DMC-HD provides a gateway for controlling the connected source device right through the HDMI connection, potentially eliminating the need for any dedicated control wires or IR emitters.
Standalone HDMI Problem Solver
In addition to its use as an input card for DM switchers, the DMC-HD may also be used with the DMCI DigitalMedia Card Interface to provide a handy problem-solving tool with many useful functions. It can be used to extract an analog audio signal from an HDMI stream, to provide a gateway for CEC device control, and to extend a USB HID mouse/keyboard signal over Ethernet. It can also be used to detect a device’s video and audio information, manage its EDID, and assess its HDCP capabilities.
To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the online DigitalMedia Switcher Configuration Tool.
