Save Satellite, Fiber & Telecom Costs:

Unique Transport Protocol Cuts Contribution & Distribution Costs in Multicamera, Live-Action Productions Making the Impossible Possible

RACK 4K & HD Encoder and PRO Series Provide Robust Transmission Over Cellular and Public Internet

Haivision RACK4 HEVC Encoder with SafeStreams for Transport over the Public Internet

Broadcast engineers and operators always look for better, more efficient ways to contribute and distribute video. It’s especially true for sports broadcasters and live-TV producers, who regularly deal with backhauling live, high-action, multicamera, multisource video, and audio. The challenge is maintaining perfect video genlock and lip sync across multiple cameras. RACK4 4K UHD & HD HEVC live encoder and PRO Series bonded cellular transmitter with Safe Streams Transport do just that. A far less costly alternative to traditional telecom or satellite connections, the HE4000 sends video through the public internet or unmanaged networks, which are practically free. Bonded cellular capability can be added to the RACK4 using the optional QUAD CellLink active antenna. For greater mobility, the PRO Series of bonded cellular transmitters provides a camera-mount or backpack alternative to satellite that is ideal for multicamera, remote integration (REMI), and at-home productions

Our project required deploying multiple systems simultaneously in areas that had less than optimal cellular service. VidOvation allowed us to test the equipment's range and capabilities in advance, allowing us to adjust our schedules and expectations. The familiarity allowed us to strategize and implement creative solutions along with backup scenarios. The technical support and brainstorming VidOvation provided made us feel that they were truly vested in the success of our show.

  • You can transport 4K UHD and HD content over the public internet at data rates as high as 100 Mbps.
  • Today people are saving 65%+ on their data costs by switching to our HEVC over bonded cellular (as compared to typical H.264.)
  • The best bonded cellular systems bond up to 11 IP connections in order to make the biggest possible transport pipe.

Major News Network Purchases VidOvation Solution for Contribution and Distribution of Live News Over Public Internet

LAKE FOREST, Calif. — April 2019 — VidOvation today announced that a major U.S. news network has made a significant purchase of video over IP transport technology. The network will use the Emmy Award-winning HE4000 HEVC live encoder for contribution and distribution of live news content bi-directionally between master control and remote affiliates using the public internet.

“Broadcasters — especially those like our new client, who depends on the ability to backhaul breaking news content from many different field locations and sources — are always looking for better, more efficient ways to contribute and distribute video,” said Jim Jachetta, executive vice president and chief technology officer at VidOvation. “With our 4 channel encoder, this high-profile new customer has embraced the potential of the public internet to help the network distribute live content to its affiliates in a far less costly manner than traditional telecom or satellite connections. The system also provides affiliates with the ability to forward live contributing content to master control. (Click to Read More)

What Is the RACK4?

The RCK4 encoder relies on the public internet to contribute and distribute video, thereby helping to eliminate high satellite costs. It is ideal for real-time delivery of live 4K UHD or HD content over unmanaged IP networks. The compact, half-RU encoder combines 10-bit and 4:2:2 HEVC encoding with the latest generation of SafeStreams technology to deliver live video over IP at low latencies and bit rates. The enhanced HEVC can save customers more than 65% on their data costs when used over bonded cellular compared to typical H.264.

SafeStreams: A Transport Protocol Like No Other

HD & UHD Contribution over the Public Internet using Haivision SafeStreams

HD & UHD Contribution over the Public Internet using SafeStream

SafeStreams Transport Protocol

Ultimate Reliability

Using SafeStreams — which incorporates IP bonding techniques, precision timing over bonded cellular and the public internet, and adaptive-bit-rate encoding — provides a robust transmission. That’s because of multiple layers of redundancy:

  • SafeStreams automatically recovers dropped packets through dynamic 2D forward error correction.
  • Additional lost packets are recovered using advanced ARQ.
  • Finally, the protocol itself also has a built-in level of redundancy, which can be set as high as 100% so that each packet is transmitted twice.

Greater Speed and Agility

SafeStreams lets users record, store, and forward HE4000 4K UHD and HD contents at low bit rates. It gives the HE4000 the ability to transport 4K UHD and HD content over the public internet at data rates as high as 100 Mbps. Furthermore, it bonds up to 11 IP connections (up to eight cellular, two LAN, and one Wi-Fi) to create the biggest possible transport pipe. LAN connections can be a telecom circuit, public internet, satellite, and more. When using the HE4000 over cellular networks, the use of one or two QUAD CellLink is required to provide up to eight modems with high gain antennas.

Robust Transmission

This solution is special because of its patented high-gain, long-range antenna, which eliminates cross-coupling and interference compared to consumer USB modems. The PRO Series high-gain antenna means signals are more likely to get picked up by a cellular tower.
