The latest IP-controlled video hardware units.
Made for routing RGBHV video and balanced or unbalanced audio, the Knox Video Technologies RSIII series of routing switchers includes units from 4x8 to 12x8 in capacity. These can also handle RGBS, RGsB, HDTV, component, S-Video, and composite video signals with volume and tone attenuation on the matrix outputs. The RSIII is controllable through RS-232 and Ethernet ports on the rear panel.
Housed in a compact 1RU enclosure, the VP-437xl seven-input scaler/switcher from Kramer Electronics handles composite, S-Video, component, computer graphics video, and HDMI with unbalanced stereo and S/PDIF audio. It outputs to RGBHV, HDMI, and VGA. HDCP capability allows the HDCP content at the input to pass only to the HDMI output. Control is done through front-panel, RS-232, IR, or Ethernet interfaces.
The Nvision compact routers from Miranda Technologies can switch 3Gbps HD/SD, SDI, analog video, AES, and analog audio and machine control in matrixes from 16x4 up to 32x32. They can be used as standalone devices in broadcast, mobile, and postproduction, needing no controller but can be combined with controllers into larger systems. The control panels, sold separately, can communicate remotely via Ethernet.
MultiDyne designed the EOS-4000 series optical routing switchers to handle single- and dual-link DVI, RGB-HV, SDI, HD-SDI, 3G HD-SDI, and future standards up to 10Gbps over fiber optics using 850 nanometer, 1300 nanometer, and 1550 nanometer wavelengths. The units can be controlled via Ethernet with AMX or Crestron controllers along with WebX, an embedded web GUI for remote control from a browser using SSL for security. The units also have hot-swappable fans, port cards, and power supplies.
For high-bandwidth optical video switching, Opticomm offers the OptiLynx OLX-3000. Available in several sizes, the OLX-3000 uses small form-factor pluggable (SFP) connectors and can switch digital signals up to 4.25Gbps. The unit’s 10/100 Ethernet connection enables switching control along with automatic and remote reconfiguration and fault emulation. It can also provide remote dynamic device testing along with cable and hardware diagnostics.
The Cheetah 144NE fiber-optic router system from Pesa Switching Systems is intended for pro AV or broadcast in dual-link DVI, HD-SDI or 3G-SDI applications. Available in sizes from 36x36 up to 144x144, the Cheetah 144NE uses I/O cards allowing expandability in groups of 36x36 using standard LC type fiber SFP modules. The unit can be controlled over Ethernet using third-party controllers or on the Web using the Pesa Clikcontrol network software.
Thinklogical designed the VX160 6.25Gbps router and non-blocking matrix switch to carry video and peripheral signals on single-mode or multimode fiber in configurations from 20x20 up to 160x160. For mission-critical applications, the unit has hot-swappable power supplies, cooling fans, and pluggable optics. The VX160 can be controlled via RS-232 with third-party control systems or on Ethernet with two RJ-45 ports. One of these is dedicated to maintenance and the other is for VX160 control.
The C2-7110 nine-input video processor from TVOne is intended to switch video signals between a variety of formats in a small 1RU enclosure. With two independent video processing and scaling engines, the unit can input composite, S-Video, and DVI-I along with reference genlock signals and output all of these in many combinations among three operational modes. Also available are chromakey, edge blending, transcoding, gamma correction, logo insertion, scaling, and proc amp adjustments. Control options include front panel, serial, and an RJ-45 IP port.
The Utah-100 family of routing switchers from Utah Scientific are available in boxed-frame and modular units for handling all video signal types in configurations from 8x8 all the way up to 32x32. Supplied with a built-in Ethernet control interface, the Utah-100/X switcher can be controlled through a browser interface or with optional built-in or remote control panels. A wide variety of signal handling options are available depending on the specific type ordered.
