Routers & Video Production Switchers
- By David Kirk
Contributing Editor David Kirk examines the latest technology for video broadcast routers and production switchers…
One-size-fits-all has never been a characteristic of the broadcast TV and radio production business. An increasing number of vision mixer designers are nevertheless attempting to advance from dedicated mix/effects systems into the all-in-one ‘OB-van-in-a-suitcase’ model. This makes good sense given the increasing adoption of IP-linked production techniques, the virus-induced expansion of home-studio activity and the ever declining cost of onboard high-speed ISO-capable multichannel data storage.
The sharp end of the story is the price. High-specification production equipment is becoming ever more affordable. Battleship-grade construction always costs more and relatively low-cost portable control-room-in-a-box hardware is becoming increasingly available. Router design remains for the present more traditional but that category too is evolving to offer greater matrix capability within a given space. A logi-cal next step would be for mixing and routing to be performed within the same device but there at least modularity is likely to survive.
Meanwhile, what’s new... Routers & Interfaces
Cobalt Digital has acquired the IP and manufacturing rights to multiple Ward-Beck openGear cards. Products being integrated into the Cobalt family include analog audio and video distribution amplifiers, audio analog-to-digital /digital-to-analog converters and single card rear modules in three-pin terminal block configurations. Ward-Beck Systems manufactured and supplied professional audio broadcast equipment for more than half a century from headquarters in Toronto. The company ceased operations on January 31st, 2021, but continued support and assistance during the transition period.
For-A has introduced two new 12G/6G/3G/HD/ASI routing switchers The MFR-4100 and MFR-6100 support 12G-SDI cabling which carries 4K content over a single crosspoint. The MFR-6100 configures a matrix of up to 36 x 36; the MFR-4100 configures up to 18 x 18. The routing switchers automatically sense the type of SDI input. Both models feature multi-format I/Os, SNMP monitoring and multiple redundancy options including CPU and power supply.
NTP Technology has expanded its Penta audio interfacing platform with three new 1 RU models: Penta 721s, 721s-DNT and 721s-SDI. Each includes AES, MADI and Dante I/O. The 721s-DNT is a Dante to Dante converter with sample rate conversion on the input for connecting individual IP Audio networks that can run on different sample rates and digital clocks. Dante connectivity takes the form of a 64-channel Brooklyn module; the 721s-DNT adds another 128 channels and onboard sample rate conversion. The 721s-SDI adds dual 3G SDI embedding/de-embedding for broadcasters needing to combine SDI signals with Dante, MADI or AES. The SDI side of the model also has built-in sample rate conversion. The 721s comes with slot for any of seven available expansion cards such as analog inputs or outputs, delay processing for lip-sync, 3G SDI, or additional AES, MADI or Dante connectivity. “The new Penta 721s models build on the legacy of the modular Penta 720 unit which serves in countless enterprise audio solutions throughout the world,” comments NTP Technology Sales Director Mikael Vest. “We already know that AoIP will increasingly become the backbone of any larger enterprise audio facility, yet older audio formats will remain part of the systems for some time. With the Penta 721s and Penta 721s-SDI we’re covering any existing audio format around, while the Penta 721s-DNT is ready to engage any Dante/AES67-based system today or in the future.”
Pesa claims its Tiger Fusion 12G SDI/IP video distribution system is the world’s largest single-link 4K matrix. Single-link 12G design reduces cabling and simplifies management. A mix of SDI (1.5, 3, 6, and 12G), HDMI (1.4, 2.0), and IP (SMPTE ST 2110) I/Os can be accommodated within an 18 RU frame. “Tiger Fusion meets the need for simplified management of large 4K installations via single-link 12G SDI,” said Pesa CTO Scott Barella. “With our flexible signal-agnostic control system, it enables hybrid workspaces using SMPTE ST 2110 IP gateways and HDMI 2.0.”
