Continuing to showcase its innovative solutions for video broadcast, Gennum Corporation demonstrates the industry's highest speed, highest performance video transport leveraging its optical technology.
The unprecedented signal integrity achieved at 12 gigabits per second (Gb/s) validates the video industry's ability to move to even higher resolution video formats, to transmit multiple high rate streams across a single optical link and to support emerging high rate standards. The demonstration is being held at Gennum's booth at the International Broadcast Equipment Exhibition (Booth 5601), November 20-22 at the Makuhari Messe Convention Center.
"Just as we did in the early days of SDI, Gennum continues to innovate in order to enable our customers to move to the next level with their video streaming applications," said Martin Rofheart, Senior Vice President and General Manager, Analog and Mixed Signal Division. "This demonstration highlights the broad possibilities for our video customers to move even higher rates of video through their infrastructure.
As important, new and emerging standards such as Ultra-High Definition TV and D-Cinema are now within reach, as these data rates will support the delivery of content that meet the high quality requirements of these and other standards."
Gennum's demonstration leverages the company's leading clock and data recovery (CDR) technology for video optical module applications, which enables the maximum signal integrity at these higher rates to deliver high quality video. The module, a standard off-the-shelf XFP transceiver modified to include Gennum's 12.5G CDR test chip, is capable of variable data rates from 9.9Gb/s to 12.5Gb/s.
This variation enables support for a broad range of current and emerging standards, such as UHDTV, Society of Motion Picture and Television Engineers (SMPTE) 435M, D-Cinema, 12-bit 4:4:4 1080p. Additionally, the high bandwidth enables up to eight HD-SDI links or four 3Gb/s-SDI links, creating new possibilities for design of serial routing and distribution equipment.
"We welcome demonstrations of this nature," said Peter Symes, Director, Standards and Engineering, of SMPTE. "We expect to create standards and specifications for motion picture applications at ever higher data rates, and proof of concept is essential to the credibility and focus of the work."
