AJA Bridge Live

Overview
The BRIDGE LIVE family are the broadcast quality, low latency turnkey systems for REMI, Synchronous Multi-Channel Video Contribution, Remote Collaboration, Direct to Audience Streaming, and Multi-Bitrate/Multi-Format Delivery via a wide range of IP video standards and/or SDI. New to the BRIDGE LIVE family is the BRIDGE LIVE 3G-8, a high-density HD version of BRIDGE LIVE, which supports up to 8x bi-directional 3G-SDI I/O.

BRIDGE LIVE and BRIDGE LIVE 3G-8 were developed as a collaboration between AJA and Comprimato to deliver the performance, reliability, and ease of use necessary for critical live encode, decode, or transcode needs. Equipped with either 12G-SDI I/O or 3G-SDI I/O with the power and flexibility to enable real time, bidirectional encoding, decoding, and transcoding for critical UltraHD or HD workflows, BRIDGE LIVE is an essential part of any modern video production toolkit. A compact and robust 1RU form factor, with redundant power supplies, and a three year warranty, means peace of mind even when dealing with the most demanding applications.

Whether facilitating remote production, interviews, live event streaming, synchronous multi-camera backhaul with HDR, cloud contribution, program return, confidence monitoring, collaborative production, or ABR ladder profiles to hand off for OTT packaging, BRIDGE LIVE ensures simultaneous, secure, and reliable workflows over purpose built dedicated lines or the public internet.

BRIDGE LIVE FAMILY I/O Overview
The BRIDGE LIVE family of products, BRIDGE LIVE and BRIDGE LIVE 3G-8, support the most widely used IP video compression schemes and transport protocols to solve your workflow needs. The BRIDGE LIVE family supports conversion to/from SDI to numerous IP video solutions and well as pure IP conversion and distribution workflows.

Simultaneous Bidirectional Encoding and Decoding
BRIDGE LIVE supports simultaneous bidirectional encoding and decoding from UltraHD (BRIDGE LIVE only), HD, and SD sources. Both models support up to UltraHD from IP-based sources.

For example, with a pair of BRIDGE LIVE systems, a broadcast facility can receive three incoming encoded camera sources from a remote location and decode them back into SDI for editing and production while simultaneously providing program return to the remote location. This example shows 4 channel capability on BRIDGE LIVE, while BRIDGE LIVE 3G-8 supports up to 8 HD channels.  

NDI Encode/Decode/Transcode
BRIDGE LIVE includes support for NDI (Network Device Interface), the high quality, real time, low latency IP video standard developed by NewTek. BRIDGE LIVE can support up to 8x simultaneous 60p HD NDI encodes/decodes or 1x 30p UltraHD NDI encode/decode to/from SDI (BRIDGE LIVE model dependent). BRIDGE LIVE’s NDI functionality offers:

• SDI to NDI (encode)
• NDI to SDI (decode)
• IP Video Streams to NDI (transcode)
• NDI to IP Video Streams (transcode)
• Multiple Discovery Servers

Used in conjunction with BRIDGE LIVE's broad codec and protocol support, collaboration between geographically separated (remote) NDI facilities can be realized. BRIDGE LIVE provides broad NDI compatibility with 3rd party NDI software and hardware transmitters and receivers.

Synchronous Multi-Channel Transport
BRIDGE LIVE and BRIDGE LIVE 3G-8 support independent SDI source inputs and maintains their synchronous relationship while transporting the content to end-point destinations.

This functionality can take place between a pair of BRIDGE LIVE units for a synchronous end-to-end SDI workflow, often referred to as SDI backhaul, or site-to-site SDI workflows.

BRIDGE LIVE’s synchronous multi-channel capability is also supported for cloud contribution, whereby a BRIDGE LIVE system can send signals to a Comprimato Live Transcoder cloud instance, thereby ensuring multi-source synchronicity for delivery to various CDNs, platforms, and cloud services as IP video.

Furthermore, Synchronous Multi-Channel Transport can be scaled up from a single BRIDGE LIVE pair to additional BRIDGE LIVE pairs to enable workflows where multiple BRIDGE LIVE systems can receive SDI and send to multiple BRIDGE LIVE systems outputting SDI, all in synchronicity.

HDR is also supported for end-to-end SDI workflows.

SRT Ready
SRT is an open source video transport protocol and technology stack that optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over questionable networks. 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. Encryption built into the SRT protocol ensures secure streaming video content delivery with low latency and secure reliability.
