Replacing satellite contribution

Replacing satellite contribution

An interesting story from the US, where ONN (Ohio News Network) is using Haivision and Zixi gear for cost-effective video contribution to 16 cable headends across Ohio and surrounding areas.

Perhaps even more to the point, the pairing of Haivision’s Baracuda encoding technology with the Zixi platform in a turnkey solution has enabled ONN to shift from costly satellite contribution to high-speed IP video delivery over the public Internet — without otherwise altering its working environment or processes.

"We relied on satellite delivery at 9Mbps for nearly 15 years, but now with Haivision’s remarkably efficient H.264 encoding and Zixi’s content broadcast and media management hub, we can deliver the same quality signal over a standard IP connection using a third of the bandwidth," said Pat Ingram, director of engineering at ONN. "Without changing any part of our production workflow, we’ve been able to realize reliable, realtime point-to-multipoint delivery at a fraction of the cost of our earlier long-haul video delivery model."

Video from the ONN studio is encoded by two Barracuda encoders, sent to the Zixi Feeder and Broadcaster, which sends the signal over the public internet to Zixi Receiver units installed at each of the 16 headend locations. There, the stream is processed by a decoder, which provides SD-SDI video for cable broadcast. This new solution boasts no packet loss and extremely low jitter and provides 24/7 always-on performance, which ONN engineers can manage and monitor through the platform’s intuitive interface.

"ONN was able to install this new IP solution with complete transparency, and going forward, the station can just as easily expand the system to add channels or extend high-quality video to additional headends," said Peter Maag, senior vice president at Haivision. "The installation at ONN demonstrates how simply broadcasters can employ advanced encoding and delivery solutions to realize significant cost savings with virtually no impact on operations or video quality."
