DigitalMedia 8G+® Technology
As the leader in HDMI and control system technologies, Crestron developed DigitalMedia technology to deliver the first complete HD AV distribution system to take HDMI technology to a higher level. A DigitalMedia system allows virtually any mix of HDMI and other AV sources to be distributed throughout a room, building, or campus. The latest generation of a DigitalMedia system uses DigitalMedia 8G+ technology. Engineered for ultra high-bandwidth and ultimate scalability, DigitalMedia 8G+ technology provides true one-wire lossless transport of high-definition video, audio, Ethernet, and control signals over a choice of twisted pair or fiber optic cable.
A DigitalMedia 8G+ system handles uncompressed Full HD 1080p, Ultra HD, 2K, and 4K video signals with support for 3D, Deep Color, and HDCP 2.2. Audio capabilities include the simultaneous distribution of stereo and multichannel surround sound signals, with support for high-bitrate 7.1 audio formats such as Dolby® TrueHD, Dolby Atmos®, and DTS-HD Master Audio™ as well as uncompressed linear PCM. All signals are transported over one CAT type twisted pair cable or one strand of multimode or single-mode fiber. DigitalMedia 8G+ technology enables wire distances up to 330 feet (100 m) via twisted pair copper wire[5,10], 1000 feet (300 m) via DM 8G Fiber (DM 8G over multimode fiber) [6,10], or 7.5 miles (12 km) via DM 8G SM Fiber (DM 8G over single-mode fiber) [7,10].
The DM-MD32X32-CPU3 provides full support for Crestron DigitalMedia 8G+ devices as well as all first-generation DM CAT [8,10] and DM Fiber [9,10] products, letting you take advantage of the latest Crestron DigitalMedia 8G+ technology without compromising your existing investment.
DigitalMedia 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with other HDBaseT certified products. Using DigitalMedia 8G+ technology, the DM-MD32X32-CPU3 can be connected directly to an HDBaseT compliant device without requiring a DM transmitter or receiver.
High-performance H.264 streaming capability enables enterprise-wide distribution of HD content over an IP network. Streaming expands the capabilities of a DM system by removing all distance limitations and allowing distribution to virtually any device — anywhere in the world. Streaming is an essential component of any complete DM system, allowing for high-definition signal routing to Crestron touch screens, digital signage displays, remote buildings, and global offices without requiring any new or dedicated wiring. Large-scale streaming to computers and mobile devices can be facilitated through integration with a streaming media system such as a Wowza® or Kaltura® media system.
A DigitalMedia system with streaming affords the ability to distribute any combination of sources to virtually any device anywhere. Each streaming output supports resolutions up to HD 1080p at bitrates up to 25 Mbps. Built-in scaling enables fast, trouble-free switching between sources of any type or resolution up to 1080p or WUXGA. Audio support includes stereo signals, as well as multichannel audio signals downmixed to stereo via any ”DSP” type input card. High-quality video and audio is maintained using high-performance H.264 video and AAC audio compression. The encoded video and audio can be output as independent RTP streams or encapsulated in an MPEG-TS (MPEG-2 Transport Stream) container. HDCP management ensures that protected content cannot be distributed via streaming.
Each streaming output is actually fed internally by two separate switcher outputs, allowing any two input sources to appear picture-in-picture or side-by-side in a single stream. Instant, single-frame switching between two full screen images is also possible. The audio signals from both input sources can also be mixed, allowing both signals to be heard simultaneously.
The DM-MD32X32-CPU3 can receive streaming signals as well as transmit them. Streaming input capability enables IP cameras and other H.264 encoded sources to be distributed via DigitalMedia alongside HDMI and other non-streaming sources. It also allows DM switchers to be bridged together across a campus or around the world, enabling simplified routing of HD content between buildings and global offices.
A DigitalMedia system provides many deployment options to address a wide range of streaming applications and accommodate each organization’s specific IT requirements. A DigitalMedia system with streaming supports both unicast and multicast, with or without RTSP (Real Time Streaming Protocol). Streaming connections can be configured to stream directly to one or more specific IP addresses, or to use RTSP to manage the configuration of numerous connections automatically.
Built-In CONTENT LAN Port
A streaming input or output may be configured to stream via the CONTENT LAN or LAN port of the DM switcher or via a dedicated CONTENT LAN port of a DMC Series input or output card. Control and content can be combined on a single network or can be isolated onto separate networks.
The DM-MD32X32-CPU3 features a modular architecture with 32 input card slots, and 16 dual output card slots. Each card slot on the DM-MD32X32-CPU3 is field installable, allowing for easy and flexible system configuration with the ability to make changes to the system as needs change. A wide selection of input cards is offered to support a complete range of digital and analog AV signal types including HDMI, DVI, Dual-Mode DisplayPort , SDI, RGB/VGA and analog video, SPDIF and analog audio, HDBaseT, H.264 streaming, and all types of DigitalMedia. Available outputs include all types of DigitalMedia, as well as HDBaseT, HDMI, analog audio, and H.264 streaming.
An HDMI “pass-through” output is provided on every input card to allow the inputs of up to five DM switchers to be daisy-chained, enabling the configuration of very large distribution systems with many outputs. Using five DM-MD32X32-CPU3 switchers, it is possible to support up to 160 separate outputs.
Handling high-definition digital media means handling HDCP (High-bandwidth Digital Content Protection), the encryption scheme that content providers use to protect their DVDs, Blu-ray™ discs, and broadcast signals against unauthorized copying. Viewing HDCP encrypted content requires a source device to “authenticate” each display and signal processor in the system and issue it a “key” before the content can be viewed. Ordinarily this causes a complete loss of signal for up to 15 seconds each time a new source or display is selected anywhere in the system. To make matters worse, every source device has a limited number of keys available, so connect too many displays and the source will simply stop outputting a signal without warning.
Not to worry — Crestron QuickSwitch HD manages the keys for every HDCP-compliant device in the system, maintaining continuous authentication for each device to ensure fast, reliable routing of any source to any number of display devices.
Crestron Auto-Locking Technology enables super fast signal switching by instantaneously configuring every device in the signal path as soon as the signal hits the first device. Whether switching between sources or TV channels, Auto-Locking technology significantly reduces the time it takes each device to sense the new signal and configure itself to handle the changes, virtually eliminating any noticeable gap while switching.
EDID Format Management
With all of today’s varied AV sources comes a multitude of confusing video and audio formats to keep track of, and chances are not every device in your system supports all of the same formats. Such conflicts can wreak havoc any time you route one source to more than one display or audio component. The media source feeding your 1080p or Ultra HD projector in the theater may restrict itself to a lower resolution, or even shut off completely, if someone decides to view the same signal on a smaller TV in another room. And, instead of enjoying your theater’s incredible 7.1 surround sound, you may find yourself limited to 5.1 or even plain old stereo.
DigitalMedia technology eliminates such conflicts by managing the EDID (Extended Display Identification Data) that modern digital devices use to communicate their capabilities. Via Crestron Toolbox software, the format and resolution capabilities of each device can be assessed, allowing the installer to configure EDID signals appropriately for the most desirable and predictable behavior.
A Scaler for Every Display
High-performance scaling capability can be added to any DM system using select output cards and DM receivers with built in HD and 4K scalers. By placing an independent scaler at every display device, DigitalMedia technology truly delivers the most flexible and user-friendly solution for routing multiple disparate sources to many different display devices. This “Distributed Scaler Approach” ensures an optimal image on every screen no matter what sources are selected. Distributed scaling allows a high-res computer source to be viewed on any display in the building. It also allows an SD, HD, or Ultra HD video source to be viewed simultaneously on the 4K display in your theater and on lower resolution displays throughout the house.
Versatile Audio Routing
HDMI technology is the key to handling 7.1 surround sound formats such as Dolby TrueHD, Dolby Atmos, and DTS-HD Master Audio. Great for your high-end home theater, but how do you share that same source with other audio zones in the house?
DigitalMedia technology provides the answer, allowing for the simultaneous distribution of multichannel surround sound and two-channel stereo signals from the same HDMI source. Using a choice of ”DSP” type input cards, the DM-MD32X32-CPU3 employs onboard digital processing to derive a stereo downmix from the original multichannel signal. Both signals can be routed separately or simultaneously from any of the switcher’s DM outputs, allowing either signal to be selected for output at each DM receiver location.
Back at the switcher, the digital stereo signal is also converted to analog to enable sharing with every other room in the house via a Sonnex® Multiroom Audio System or any other audio distribution system. The DM-MD32X32-CPU3 also allows surround sound processors and amplifiers to be located centrally instead of at the display location via optional local HDMI outputs.
Built-in Ethernet Switch
In addition to transporting digital video and audio, a DigitalMedia system can also extend 10/100 Ethernet out to each display and source device via select DM receivers and transmitters, providing high-speed connectivity for any room device that requires a LAN connection. Ethernet is also utilized internally by the Crestron control bus to manage the DM devices in the system and provide display control in each room.
Private Network Mode
To streamline its implementation on a corporate or university LAN, the DM-MD32X32-CPU3 employs Private Network Mode to provide a single-point connection for the complete system. Using Private Network Mode, the DM-MD32X32-CPU3 requires just one IP address for the complete DM network including all connected DM receivers and transmitters.
USB Signal Routing
Along with video, audio, and Ethernet, a DigitalMedia system also provides for the routing of USB HID (Human Interface Device) signals, allowing a USB HID compliant keyboard and/or mouse at one location to control a computer or media server at another location. USB HID connectivity is provided through select DM receivers, transmitters, and input cards.
Crestron also offers USB extenders to enable the routing of virtually any type of USB peripheral to any host device, all managed through the DigitalMedia system. Connect a USB over Ethernet Extender host module (USB-EXT-DM-LOCAL ) to each computer, media server, game system, annotator, and any other host that you want to control or communicate with. Then, install a device module (USB-EXT-DM-REMOTE ) at every display location to connect keyboards, mice, game controllers, whiteboards, flash drives, Web cameras, and mobile devices. Every module communicates with the DM switcher over the local Ethernet network or via a direct connection to the LAN port of a DM transmitter or receiver.
CEC Embedded Device Control
The primary objective of every Crestron system is to enable precisely the control desired for a seamless user experience. DigitalMedia technology provides 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 the control system, the DM-MD32X32-CPU3 provides a gateway for controlling many devices through their HDMI or HDBaseT connections, potentially eliminating the need for any dedicated control wires or IR emitters.
Via the front panel or using Crestron Toolbox software, every step of the DM-MD32X32-CPU3 setup process is designed to be quick and easy, configuring inputs and outputs automatically while letting the installer make intelligent design decisions along the way. The switcher even tests and measures the length of each DM cable, automatically making the appropriate calibrations for optimal signal transmission to every room. An entire DigitalMedia 32x32 system can be commissioned in under an hour.
Web Browser Control
The DM-MD32X32-CPU3 also includes a built-in web server that allows functions such as Ethernet configuration, routing, and firmware upgrades to be performed.
