The Protocol for Modern Video Workflows
ART is a streaming protocol that delivers secure, ultra low latency (ULL), broadcast-quality audio and video over the public Internet. ART utilizes joint source channel coding to evaluate video content and network characteristics simultaneously, optimizing for both in one step. The result is a highly resilient, adaptive video stream that ensures the quality and integrity of your content over the most challenging network conditions.
ART currently supports: Real-time, bi-directional streaming between two ART systems over a LAN or WAN. Point-to-point streaming from ART encoder to decoder. Distribution from 1 ART encoder to multiple ART decoders through Teradek's Core cloud platform or over a LAN. Multicast over a LAN
POINT-TO-POINT (WAN)
The ART 2U system can stream unidirectionally over a WAN to other ART systems. With a second ART system, it can operate bidirectionally: delivering real-time, broadcast-grade audio and video for interviews and interactive media. For remote monitoring and configuration of your ART devices, an optional subscription to Core Cloud is available.
POINT-TO-MULTIPOINT (WAN)
With Teradek’s Core Cloud platform, ART 2U can distribute a single video feed to multiple ART systems, all while maintaining an extremely robust, ultra-low latency stream.

THE VIDEO-AWARE ULTRA-LOW LATENCY STREAMING PROTOCOL
ART is a UDP video streaming protocol that delivers ultra-low latency (ULL) audio and video with mission-critical resilience over public and private networks. The protocol was jointly developed by Teradek and Amimon using the same methodology behind Teradek’s Emmy® and Academy Award®-winning Bolt wireless video system.
- <100ms latency over WAN
- AES-256 encryption
- Easy firewall traversal
- No re-transmission delays
- Rapid recovery over
- challenging networks
- Support for HD and
- 4K workflows
HOW DOES IT WORK?
ART evaluates both video content and network characteristics simultaneously, optimizing the compression for both in one step. The protocol is adaptive and utilizes joint source channel coding, which offers robust FEC to the most significant video information, eliminates re-transmission delays, and constrains the peak bitrate.
HOW IS IT USED?
ART is designed for use in point-to-point video workflows (P2P) and multipoint distribution when used in conjunction with Teradek’s Core cloud platform. Typical solutions for the protocol include remote and interactive live productions, robotic / vehicular teleoperation, and real-time monitoring and collaboration.
HOW DOES ART COMPARE?
Low latency streaming protocols like SRT introduce delays that are noticeable by the user, particularly so when video is required for remote control: cloud gaming, remote machinery, and remote driving. Despite increasing Packet Error Rates (PER) and Round Trip Time (RTT), ART’s streaming latency does not significantly increase as it does from others like SRT.
WHY DOES ART MATTER?
ART overcomes the challenges of streaming over lossy public networks, namely video pixelation, stuttering, freezing, sync loss, delays, and total dropouts; all whilst retaining ultra low latency. It is the only protocol that optimizes for both video quality and network characteristics simultaneously, delivering the best possible streaming experience despite network performance. Video freezes are extraordinarily rare due to ART’s ability to smoothly adapt to varying network conditions.
ART Provides:
- More natural, lifelike bi-directional streaming interaction between anchors and guests
- Graceful degradation and rapid recovery over networks with significant packet loss
- Easy firewall traversal with various operational modes
- Constrained peak bit rates and no re-transmission delays
- Extreme resilience over challenging networks
- Forward Error Correction (FEC)
- Rapid recovery when the network returns to normal
HOW IS ART DIFFERENT FROM SRT?
Unlike SRT, ART does not require retransmissions. Instead, ART relies on a combination of patented techniques and Forward Error Correction to retain its ultra low latency despite poor network conditions.
