Haivision’s HE4000 4K & HD Encoder and PRO Series Provide Robust Transmission Over Cellular and Public Internet

Broadcast engineers and operators are always looking 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. Haivision’s HE4000 4K UHD & HD HEVC live encoder and PRO Series bonded cellular transmitter with SafeStreams® technology 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 HE4000 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.

What Is the HE4000?

Haivision’s HE4000 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. Haivision’s 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

Inherent in the HE4000 encoder is Haivision’s patented SafeStreams transport protocol, which provides reliable, broadcast-quality video transmission over 3G/4G cellular, LAN, Wi-Fi, satellite, and the public internet with advanced forward error correction, dynamic automatic re-requests (ARQ), and up to 100 percent redundancy.

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.

Achieving the Impossible on “Live PD”

A&E’s highly popular “Live PD” captures and streams live video of police officers on patrol in six jurisdictions around the U.S. It’s a REMI production that runs as many as 36 live cameras feeds back to a New York control room. The major challenge was how to produce this live cop show cost-effectively and home-run all those cameras from multiple police vehicles simultaneously — sometimes during a high-speed chase going 130 miles per hour. With so many feeds, traditional satellite or microwave links are not a viable option.

Haivision bonded cellular gear with SafeStreams achieved what no other system could: simultaneous transmission of 36 live video streams up to 3,000 miles away, with perfect multicamera genlock synchronization and lip sync. It’s a major feat of broadcast engineering. The “Live PD” crew uses 36 PRO180-RA bonded cellular transmitters — one for each of two HD cameras in every patrol car and the two camera operators in the

back seat. Four QUAD high gain, external antenna units are installed on each patrol car so the transmitters in the trunk can receive a strong and resilient signal.  The transmitters feed up to four video channels and eight audio channels of live, high-quality video back to the control room in New York from every patrol car in all six cities. In the control room, the Haivision StreamHub transceiver, decoder, and distribution
platform receives the live video feeds and dumps them into an instant replay system, which delivers the video to air for the live broadcast. A genlock input on the transceivers is instrumental in providing multicamera genlock capability to maintain synchronous cameras and perfect lip sync. If the Haivision PRO series of bonded cellular transmitters with SafeStreams can work for an unprecedented, challenge-ridden REMI production like “Live PD,” imagine what it can do for multicamera news, live sports, and events.

“With the first season of ‘Live PD,’ the Haivision gear enabled us to prove the concept of bonded cellular technology for capturing large quantities of high-quality live HD video from multiple cameras and then streaming it to air in real time. The PROs allowed us to accomplish our creative goals for the show in a highly cost-effective manner, and we could not have been happier with the gear’s performance. Therefore, it made complete sense to make a long-term investment in Haivision technology to keep pace with the ever-expanding scope of the show. Other competing systems”

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.
