Routers and Switchers

The biggest challenge facing switchers and routers is the wide variety of digital and analog video formats being used. Manufacturers have noted that this trend will continue and have responded with switching systems that can be easily customized. Asymmetrical input/output capacity, automatic signal format recognition, and integral EDID management represent a few of the capabilities that today’s routers include. The systems listed here are typical of the hardware brought to the task.
Altinex has provided a number of control options for the MX430-101 HDCP-compliant 8x8 HDMI matrix switcher including RS-232, optical or wired IR, and the front-panel buttons that can store and recall up to six snap-shot configurations. The unit regenerates and re-clocks output signals and can handle EDID automatically from the first recognized display, or allow the user to select a resolution from an internally stored table. The switcher supports HDMI V1.3 with deep color and audio formats including Dolby TrueHD, Dolby Digital Plus, and DTS HD Master Audio.
The latest switcher from AMX, the Enova DGX 32 Enclosure, can be fitted with any combination of input and output boards and features an integrated NetLinx controller, embedded Ethernet switch, and redundant power supplies. Paired with DXLink transmitters and receivers, the system can send analog and digital video, including HDMI/HDCP, on twisted-pair cables up to 100 meters long. The system uses SmartScale Technology to set the resolution to optimum for each connected display rather than the best one common to all. The DGX 32 Enclosure will pass Ethernet and stream IP video, and it fits in a 6RU chassis.
Format versatility is the hallmark of the Analog Way SMX200 Smart MatriX 12x2 scaled matrix switcher. The unit includes analog video inputs on 15-pin Sub-D, DVI, SD/HD-SDI, and computer formats up to 2K, while the outputs include computer 2K, DVI, and RGBHV. The switcher features quad scalers, and it can produce live transition effects for presentations and up to two PIPs on a still background on each output. It can also be set up with eight presets per output and a variety of remote control options.
The AT-HDDVI1616-AM 16x16 DVI and audio matrix switcher from Atlona is HDCP compliant and it has three remote control options including RS-232, IR, and LAN in addition to the front-panel buttons and LCD. It has nine programmable presets with independent audio and video routing capability, and non-volatile memory can save the EDID configuration seen on each input port. Switching is as fast as half a second, and there is support for resolutions up to 1920x1200 or 2Kx1K. The 4RU frame has a redundant power supply that can take over if the primary fails.
The card frame of the DXM3232 digital media card cage matrix system from Aurora Multimedia can be fitted with any combination of input and output cards including HDMI, DVI, HDSDI, VGA, Cat, and fiber. The 6RU chassis may be locally operated on the front-panel buttons and LCD screen or remote controlled via RS-232. It can fit a redundant power supply option for mission-critical applications. Nine preset routing configurations may be stored and recalled. Up to eight input and output cards may be selected, and each of these has four connection ports.
