AVIWEST’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. AVIWEST’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?
AVIWEST’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. AVIWEST’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 AVIWEST’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
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.
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.
