BRIDGE LIVE

High Performance Multi-Channel Video Encoding, Decoding, Streaming and Transcoding for Live Video

BRIDGE LIVE is a turnkey solution built for critical streaming applications with high performance 12G-SDI video encoding/decoding, stream-based transcoding, flexible I/O, comprehensive metadata support, closed caption support and all within a compact 1RU form factor with redundant power supplies.

Designed with the ability to support both low-latency and high-quality workflows across a range of codecs, containers, and protocols, BRIDGE LIVE enables numerous use cases; multi-input live streaming to platforms such as YouTube, Facebook, or Twitch, providing high quality reference video for remote collaboration in production and post, backhauling remote live SDI video sources to the media production facility, SDI to MPEG-TS conversions for Telcos/IPTV/Cable networks, through to encoding for content distribution with ABR ladder profiles or hand-off for OTT packaging, and all supported via public internet.

SRT Ready

SRT is an open source video transport protocol and technology stack, developed and pioneered by Haivision, that optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks. The SRT Open Source Project, supported by the SRT Alliance, is a collaborative community of industry leaders and developers striving to achieve lower latency internet video transport by continuously improving open-source SRT.  

BRIDGE LIVE includes SRT (plus encryption) to ensure that end users are well positioned to deliver their streaming video content securely, with low latency and secure reliability.

Transport, Encoding and Delivery

BRIDGE LIVE can be configured for low latency or high quality tasks. Depending on configuration, latency can be as low as 200ms. And, BRIDGE LIVE naturally gives you the tools to move content and deliver according to your workflow needs.  

BRIDGE LIVE supports:

  • RTMP, RTMPS (output only)
  • RTP, UDP
  • SRT (plus encryption)
  • MPEG Transport Stream
  • ABR Ladder Profiles
  • Hand-off for OTT packaging
  • Supported Encodes/Decodes

    BRIDGE LIVE supports the following configurations for encoding and decoding between SDI and streaming formats as standard. Multiple streams/formats/destinations can be derived from a single SDI input.
