BE8500 HD/SD Versatile Encoder

The Telairity BE8500 is a versatile video encoder, able to autosense either HD or SD input video formats, and automatically select a corresponding HD, SD, or Mobile encoding mode. It combines legacy MPEG-2 SD encoding ability with leading-edge compression technology (either H.264/AVC or AVS), support for both 2D and 3D formats, and the option of either 4:2:0 or 4:2:2 chroma sampling. Settable encode latencies range from 150ms to 2 seconds. Featuring "instant on" for immediate availability, simple "two button" front panel control for quick and easy field operation, wide temperature tolerance, dual redundant power supplies and external audio inputs (AES and analog stereo), the cost-effective and reliable BE8500 addresses the critical needs of broadcasters for a platform with the versatility to address any requirement.

Telestream NASCAR Project Wins IBC2012 Innovation Awards

Nevada City and San Jose, California, September 10, 2012 - Telestream®, a leading provider of video transcoding and workflow solutions, and Quantum, a global expert in data protection and big data management, today announced that the NASCAR video capture and replay project incorporating technology from both companies won the prestigious IBC2012 Innovation Award in the Content Management category. Telestream developed the video capture and replay system for NASCAR’s high-speed sports officiating. The award recognized NASCAR and its project partners, including Quantum for its StorNext data management software and CineSys for its disk storage.

“It is an honor for the NASCAR project to be recognized by the IBC,” said Barbara DeHart, vice president of marketing at Telestream. “The new race control system would not have been possible without the collective efforts of NASCARProductions, along with the Telestream, Quantum and CineSys teams. Together, we were able to bring high-quality capture and replay into the race-day operations of one of the most exciting sports around.”

In the fast-paced world of NASCAR racing, where broadcasts reach more than 150 countries, video also plays a key role in controlling NASCAR races. The new race control system is based on Telestream’s Pipeline HD hardware encoder and a new, high-performance, multi-clip Pipeline Replay application.  The scalable, file-based system provides instant capture and synchronous display of 18 high definition (HD) camera feeds, enabling instant access, search, and analysis of an entire race event.

“The instant replay system that Telestream has provided NASCAR this season has enabled our officials to perform their jobs in an even more efficient and time-sensitive manner,” said Robin Pemberton, NASCAR Vice President of Competition. “Having instant access to that many camera angles featuring such high-quality video has been a terrific addition to our race weekends.”

The race control system utilizes high-speed StorNext File System software from Quantum to provide simultaneous access of video content, including the ability to rewind and read while continuing to write from 18 HD cameras. CineSys provided on-site infrastructure, architecture, installation, and technical assistance.

”We are pleased to have been selected by Telestream to participate in this important project, and it is especially gratifying to be recognized in this prestigious award. StorNext’s robust file sharing software is fine-tuned to address the high-performance streaming needs that accompany higher resolution video. Because of our collaboration, these combined technologies are greatly improving the accuracy of race monitoring and enhancing the experience for millions of NASCAR fans,” said Janae Stow Lee, senior vice president, File System and Archive Product Group at Quantum.

The award was presented at the IBC2012 Awards Ceremony on Sunday evening, September 9 at the RAI in Amsterdam. IBC is the premier annual event for professionals engaged in the creation, management and delivery of entertainment and news content worldwide. The Innovation Awards recognize collaboration and those who push the boundaries. Telestream is exhibiting at IBC in stand 7.D16, and Quantum is exhibiting in stand 7.G30.
