ASIA-PACIFIC BROADCASTING

Communications Specialties Inc (CSI) has unveiled a number of solutions promising to improve signal distribution via fibre.

Kicking off the new range is its SMPTE-compliant Fiberlink Matrix, a 32x32 fibre-optic signal router with what CSI described as a “unique” ability to configure the inputs and outputs in any fashion.

Being fully configurable “is a very impor-tant feature of the Fiberlink Matrix”, stressed Paul Seiden, director of sales for CSI. “Now, a customer can purchase an optical matrix with the exact number of inputs and outputs they require, giving them the ability to precisely meet technical and budgetary needs.”

For example, a broadcast engineer with nine input signals to be routed to 22 destinations can purchase a 9x22 Fiberlink -Matrix, whereas a 24x24 matrix would traditionally have been required for this -application, resulting in the purchase of more hardware than necessary, Seiden said.

The 3RU-high Fiberlink Matrix is easy to operate with multi-coloured and -illuminated front-panel buttons, and can be remotely controlled via RS-232 or -Ethernet-based graphical user interface (GUI). It can also be configured with ST or LC connectors and complies with SMPTE 297-2006.

Extremely important to broadcast applications is that this optical fibre supports and handles pathological signals, and has redundant power supplies for maximum uptime.

The Fiberlink 3350 series allows broadcasters to transmit 3G, HD or SD-SDI in compliance with SMPTE 424M-2006, 292 and 259 — with or without embedded audio and data — as well as DVB-ASI over a single- or multi-mode fibre.

The transmitter features a re-clocked and equalised SDI loop-through. Signals are equalised and re-clocked prior to fibre-optic transmission. The 3351 receiver features two re-clocked SDI outputs.

Compliant with SMPTE 297-2006, the 3350 series has the ability to operate seamlessly with the Fiberlink Matrix and other SMPTE 297-2006 fibre-optic compliant devices.

“When you are dealing with high-resolution signals such as 1080p, it is critical to the broadcast professional that the signal fidelity remains intact throughout not just the fibre-optic transport but also the electrical components within the transmitter and receiver,” said John Lopinto, CSI’s president and CEO.

“By strictly adhering to SMPTE standards and designing precision equalisation and signal re-clocking technologies into this product, the -Fiberlink 3350 series delivers that level of confidence, and 3G-SDI, of course,” he added.

This series is also immune to pathological signals over the entire budget link and operating-temperature range. Available in card form and a small-footprint box version, it is ideal for various set-ups including broadcast and corporate studios and OB vehicles.

Meanwhile, the Fiberlink 3360 can transmit 3G, HD or SD-SDI as per SMPTE 424M-2006, 292 and 259. This series has the ability to embed up to eight channels (four pairs) of AES/EBU digital audio. Convenient switches on the transmitter allow the operator to either embed each pair of audio independently to strip previously-serialised audio, or pass it through without modification.

At the receiving end of the fibre-optic link, the operator can decide which audio pairs they need de-embedded.

Audio signals are not required to operate the Fiberlink 3360 link, which can be used as a stand-alone 3G/HD/SD-SDI -optical link, with previously-serialised data left intact throughout the transmission -pro-cess. Like the others, this series is immune to pathological signals over the entire budget link and operating tem-perature range.

“Broadcast professionals have come to rely on the -Fiberlink series of SDI fibre-optic transmission systems,” said Seiden. “The addition of digital audio capabilities to our 3G/HD/SD-SDI fibre--optic products enhances our already-comprehensive line of optical broadcast products.”

Signals are equalised and re-clocked prior to fibre-optic transmission. The 3361 receiver features a re-clocked SDI output.

The 3360 series, which is compliant with SMPTE 297-2006, can operate seamlessly with the Fiberlink Matrix and other similarly compliant fibre-optic devices.

CSI’s new 3G-capable Scan Do HD can convert DVI and analogue RGB computer video up to 1920x1200 into a SMPTE standard 3G, HD or SD-SDI signal for broadcast and integration into a professional video system or other broadcast-distribution channels.

Seiden said: “Our customers will be pleased to have one unit that can receive a digital or analogue input and output SMPTE-compliant SD, HD or 3G-SDI at the push of a button.

“This level of flexi-bility is very important because the broadcast professional may be using 1080i for broadcast distribution but requires 1080p resolutions that only 3G can provide for their other digital distribution channels.”

The Scan Do HD comes equipped with two copper outputs per SMPTE 424M-2006, 292 and 259, and one SMPTE 297-2006 compliant fibre-optic output. The system accepts DVI and analogue RGB input sources through its DVI-I connector and provides a convenient DVI-I loop-through port.

The Scan Do HD can also genlock to tri-level sync or black burst and provides the broadcast engineer with precision genlock phasing controls.

Each unit comes standard with abundant features, including processing controls that include brightness; contrast; saturation; hue and sharpness; pan; zoom; push-button pre-set creation; storage and recall; EDID capture and storage; and an intuitive HTML-based GUI.

Broadcast professionals can command and control all of the Scan Do HD’s functionality by utilising RS-232 or the HTML-based GUI.
