The BE8500, a H.264/AVC video encoder capable of hot-switching between a high-definition or standard-definition video source, was introduced by Telairity at HD World.

The 1-RU BE8500 works either as a full-featured HD encoder or as an SD/SDI encoder. It auto-senses whether the video source is SD or HD, and enables users to switch live between the two video formats without powering down. Switch-over conversion is virtually instantaneous, enabling a smooth transition for live or live on tape programming.

BE8500 delivers H.264/AVC (MPEG-4) compression technology capable of achieving more than twice the compression efficiency of the older MPEG-2 standard, with settable encode latencies ranging from 150ms to 2 seconds, according to the company.

Since the BE8500 is based on Telairity’s proprietary TVP2000 video processor, which delivers 50 billion operations per second, and Telairity’s custom direct-execute AVClairity encoding software, the BE8500 features the same "instant on" capability, encode latencies as low as 150ms, “exceptional reliability”, “simplicity of operation”, and full software upgradeability, the company assures.

"Our new encoder combines features widely sought by our customers in mobile production trucks and OB vans, small-market stations, IPTV, ITV, and government and military installations," said Richard Dickson, Telairity president.

"Operations that need to switch smoothly between HD and SD feeds now have the choice of a single cost-effective unit able to satisfy both of their encoding needs. Moreover, they can combine Telairity’s top-of-the-line Series 8000 HD performance with either our 150ms low-latency Series 7000 or our 500Kbps low bit-rate Series 9000 technology. This is a system that, quite literally, can do any sort of H.264 encoding a customer might need or want."
