Comtech EF Data introduced the VersaFEC Forward Error Correction. The unit provides maximum coding gain with the lowest possible latency to support cellular backhaul and other latency-sensitive voice, video and data applications.
It is a system of short-block, low latency Low Density Parity Check (LDPC) codes designed to support latency-sensitive applications, such as cellular backhaul over satellite. Designed to provide maximum coding gain while minimizing the end-to-end latency, VersaFEC provides an alternative to existing LDP and DVB-S2 codes.
At the Tektronix NAB2008 booth, the company introduced a 6lb. HD waveform monitor designed for stations launching actual high-def electronic news gathering operations.
The company developed the WFM 5000 after listening to its customers who needed a basic monitoring device that would satisfy the need to maintain the level of quality control over field acquisition they’ve grown to expect after years of SD newsgathering at a price that would not weigh heavily on their budgets, said the company’s John Hammerstrom. The WFM 5000 has a list price of less than $7000.
Besides offering a basic HD waveform monitoring function, the WFM 5000 also can be used as an HD vectorscope, picture monitor and status display for video and audio. It supports audio monitoring for 16 embedded channels of audio and one discrete AES pair and can be mounted to a tripod or atop a camera. At the booth, Tektronix showed the new waveform monitor affixed to a camera mount atop a camera as the unit might be used in real-life shooting situations.
According to Hammerstrom, the company has received thousands of requests from customers for an HD waveform monitor that would allow them to remain competitive with other stations in town without exceeding their HD infrastructure budgets.
Although there’s a rumor that show attendance is down this year, that hasn’t affected Tektronix one bit. While I was at the booth I learned that Tektronix had more than 800 people visit its booth each day this week, numbers that the company was very happy with. Amy Higgins, Americas Region PR Manager, Test & Measurement and Video products, told me that more people visited the booth in just two days during NAB 2008 than visited the booth over the total week of NAB four years ago.
She said the quality of the people who were visiting the booth was fantastic. People weren’t just stopping by to get a brochure and leave. They stayed, and they had questions and needs.
Tektronix gave us a demo of its WFM7120 waveform monitor. The unit has been upgraded to include 3Gb/s single link serial-digital-interface (SDI) support. This capability is added through two new options: a monitoring option (3G) and a jitter measurement option.
K*WILL is enabling broadcasters to seek out and find the source of lip sync problems wherever they occur. At its NAB2008 booth, the company introduced the portable VP3000, which relies on the company’s Video DNA technology to run signal analysis using double stimulus methodology.
The double stimulus approach compares an original signal source that is presumed to be error free to signal that’s been digitally process, such as a satellite feed or one that’s been encoded or decoded. Based on the original signal, the VP3000 can identify if there’s been any signal degradation, presumably caused by the signal processing. That way, broadcasters have a way to zero-in on the source of the lip syncing errors. more
IneoQuest’s mission, according to Calvin Harrison, IneoQuest’s vice president of marketing and business development, is to create products for users that help them improve their ROI, deploy services quickly and decrease operating expenses. To that end, the company has created modules that monitor a signal and, when a problem occurs, pinpoint exactly where things went wrong. One of these products is the new Cricket 8-VSB, which offers confidence monitoring of 8-VSB broadcast signals. It provides verification and troubleshooting of studio-to-transmitter link and RF coverage area. Listen to what Calvin Harrison has to say about the Cricket 8-VSB.
My first visit of the day was with Sophie Lion-Poulain and Christophe Poulain. We dicsussed three new products: the GOLDENEAGLE ATSC, NAVIGATOR DVB-SH and RELIO with SCRIPTEASY V2.
GOLDENEAGLE ATSC offers digital TV monitoring for 8-VSB and MPEG-2 for multiple stations with centralized managment. RF and MPEG-2 monitoring and transmitter remote control are all provided in the same unit.
NAVIGATOR DVB-SH is a portable T&M unit for DVB-SH developed inconjunction with TeamCast. The portable unit can be used with any frequency spectrum below 3GHz in terrestrial, satellite or hybrid networks.
RELIO is a managment unit with 64 digital inputs, 64 digital outputs, 24 analog inputs, four serial ports, two Ethernet ports, four USB ports and one phone line connector. The SCRIPTEASY graphical software includes the MASTERVIEW graphical user interface, which allows felxible creation for users to see information from and control remote equipment over a network connection.
Monday, April 7, I spoke with Simon Derry, Chief Executive of Snell and Wilcox spin-off, AmberFin. Launched this week, just in time for NAB, the new company signals a split in S&W between traditional hardware products like Alchemist and Kahuna, and software products like iCR. AmberFin‘s offering is based around the iCR software platform for mastering, QC and distribution of file-based content. more
