High-density SRT encoder/decoder for SDI up to 12G.
OSG-8971
The OSG-8971 is a powerful and adaptable hardware-based SRT encoder/decoder card for openGear.

Productions anytime, anywhere
As cloud-based and remote production workflows become more popular, the OSG-8971 serves as the backbone for transporting video streams at scale with broadcast-grade reliability, over dedicated private links or the public internet.
Connecting ground and cloud infrastructures, linking remote operators and facilities, or supporting minimal-footprint REMI operations, the OSG-8971 provides a dependable, high-quality link, ensuring that geographical dispersion is no barrier to professional productions.
Why Choose OSG-8971?
Unmatched density, form-factor and UHD support
Pack up to 10 cards into a single openGear oGX frame, enabling the OSG-8971 to support 60 x 720p/1080p or 20 x 2160p encodes/decodes per 2RU. This modular form factor and openGear platform offers efficient hardware integration and delivers true broadcast-grade reliability for 24/7/365 operation.

Reliable SRT protocol
At its core, the OSG-8971 leverages the SRT protocol. This powerful technology offers secure, low-latency, and high-quality video transport, even across unstable public networks. SRT overcomes common challenges like packet loss, jitter, and latency, bringing broadcast-grade reliability to cost-effective and widely available networks.

Advanced CODEC support
Featuring industry-standard AVC and HEVC codecs, the OSG-8971 maintains exceptional video quality while minimizing processing latency.

Flexible audio mapping
Easily configure up to 8 audio channels per video stream for complex setups like 5.1 surround, multiple languages, or various audio sources. Flexible mapping lets you route audio from any input to any SDI output channel for total control.

Bi-Directional operation
Each of the OSG-8971’s six HDBNC ports can be configured as an SDI input or output. This flexibility means a single card can handle both encoding and decoding simultaneously, reducing costs and streamlining signal flows such as backhaul setups with return feeds for monitoring. Genlock input with framesync on every decoder output ensures received streams are easily timed to your facility.

Efficient control
Gain powerful remote monitoring and control capabilities with Dashboard, a unified platform that extends beyond the OSG-8971 and oversees your entire facility. The openGear platform provides a single, centralized point of control for up to 10 cards per oGx frame, minimizing switch port usage and simplifying your control network.
