Technology Showcase: Matrix Switchers
Sep 1, 2009 2:14 PM, By Jay Ankeney
Scalability is just one feature in a long list.
Gefen also provides its 4x4 Component with Audio over Cat-5 matrix switcher that enables direct connections among any four component video sources and four displays with audio inputs and outputs in digital and analog formats. Users can opt for small individual receivers at each display to extend video and audio signals over just one Cat-5 cable up to 300 meters with a perfect replication of audio and video resolutions to 1080p.
Versatility is key for the Triton Plus routing switchers from Grass Valley because of the breadth of signal types it supports, including 3Gbps for 1080p, HD-SDI, SDI, analog video, analog audio, and data routing signal formats. Despite its small size, the Triton Plus routing switcher delivers all the value expected in a Grass Valley routing switcher. Triton Plus is available in several sizes, including 8x8, 16x2, 16x16, 2x32, and 64x64. You can select from a either a built-in control panel or 13 standalone control panels to build your system. Routers and control panels connect together using Cat-5 cables and RJ-45 connectors. In addition, Triton Plus has a matrix partitioning feature to easily create two and four levels of routing within a single chassis.
The Genesis product line from Hall Research Technologies contains both compact and high-end matrix switches for video and audio. The Genesis AV matrix switcher is a 16x16 and 8x8 VGA/HDTV design with front-panel, RS-232, and IP control, and it features wide bandwidth for resolutions to 1920x1200 or HD (1080p). The Genesis AV matrix switcher embeds video, audio, power, and RS-232 in a single Cat-5 cable. Its outputs can be blanked (video) or muted (audio), and it features a VU meter (sound level) bar graph display on the front panel with RJ-45 outputs for video-over-twisted-pair (UTP) transmission.
Since all of Harris’ broadcast equipment is 3Gbps-capable, it’s no surprise that all its HD Panacea routers offer 3Gbps performance in 1RU or 2RU sizes, giving you 1080p performance at HD-SDI (1.485Gbps) prices. The 2RU Panacea 32x32 model comes with either universal AC or DC power supplies or external (brick) universal power supplies, and it can have an integrated redundant power supply.
Harris’s Platinum MX is part of its Platinum line of routing switchers, which combines a highly robust architecture with the flexibility required to future-proof your investment. The distributed control system used in each Platinum MX routing switcher is unique in the industry in that it does not require a separate, centralized controller. Each Platinum MX frame features redundant control modules that store configuration information related to that frame in nonvolatile memory.
Comprehensive control options in the DIGI-HDMI-4X4 matrix switcher from Intelix can be accessed via its diagnostic front-panel interface, a remote RS-232 control system, IR, or over Ethernet, making the DIGI-HDMI-4X4 an easy-to-use twisted-pair routing system for high-definition audio/video distribution applications. The DIGI-HDMI-4X4 features four HDMI inputs, four HDMI outputs, and four twisted-pair extender outputs. The matrix supports 1080i and 1080p high-definition video, and it is HDMI 1.3b-compliant.
Also from Intelix come the DIGI-VGASD-8X8 and DIGI-VGASD-16X16 matrix switchers, which combine a comprehensive audio/video switcher with Intelix’s extremely efficient twisted-pair extenders. The DIGI-VGASD-8X8 and DIGI-VGASD-16X16 each boast a separate internal control matrix that provides independent bidirectional RS-232 and IR switching and distribution. Both units work with a modular receive unit, Intelix’s DIGI-VGASD-WP-R wallplate receiver, reaching out to 350ft. on a single twisted-pair cable.
A unique feature of the Chameleon 256 HB custom-configurable matrix switcher (known to insiders as the Cham256HB 16x64 RGB VO FPC IPO) from Knox Video Technologies is a 7in. HD input preview monitor on the front panel that saves money and space in its installation. The Chameleon 256 HB is a 16x64 high-definition component matrix switcher that is ideal for the hospitality market, uses a card structure that is field-serviceable, has intuitive keypad control with directions printed on a separate LCD operator’s screen, and features hot-swappable power supplies serviceable in the field. Knox Video Technologies can provide the Chameleon 256 HB in a remarkably quick one-day turnaround.
