AJA BRIDGE LIVE 3G-8 8x Bi-Directional 3G-SDI I/O 1RU Turnkey System

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 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 3G-SDI I/O with the power and flexibility to enable real time, bidirectional encoding, decoding, and transcoding for critical 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.

The BRIDGE LIVE family of products, 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 HD, and SD sources.

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 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.

BRIDGE LIVE support SRT v1.5.3, enabling redundant stream support over an ISP to ensure hitless delivery of the originating source.

Metadata, HDR, Timecode and Closed Captioning Support
BRIDGE LIVE 3G-8 fully support Closed Captioning as well as additional metadata, which is often a neglected feature set with other encode/decode solutions.

• MPEG-2 ancillary packet support, SMPTE ST 2038
• SDR/HDR Transfer Characteristics, Colorimetry, Luminance via SDI
• SCTE-35/SCTE-104 Ad insertion markers
• CEA-608/CEA-708 Closed Captioning
• Timecode
• Embedding Closed Captioning/Subtitles into H.264 SEI messages
• Metadata pass-through
• Electronic Program Guide (EPG) on input
• SEI (supplemental enhancement information) timecode insertion

Administration, monitoring, and access to both models of BRIDGE LIVE are supported via either a network browser or local monitor via the device's built-in DisplayPort. Indirect agnostic monitoring and automation are supported via both REST API and SNMP.

REMI (Remote Production) Synchronous Multi-Channel Transport
BRIDGE LIVE 3G-8 can take independent SDI source inputs and maintain 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 to a cloud instance of Comprimato Live Transcoder software for delivery to various platforms / cloud services as IP video.

REMI Synchronous Multi-Channel Transport for Backhaul
For SDI backhaul or other site-to-site SDI workflows, BRIDGE LIVE 3G-8's bidirectional functionality means BRIDGE LIVE can act as an encoder and a decoder simultaneously. As such, references to "BRIDGE LIVE Tx" or "BRIDGE LIVE Rx" are only descriptions of the unit's current status, versus products that support only encode or decode and therefore require purchasing multiple devices.

BRIDGE LIVE Synchronous Multi-Channel Transport functionality provides an easy and repeatable way to ensure synchronous SDI video sources can be fed to an encoding BRIDGE LIVE Tx, then be timestamped, transported, and ultimately output from the decoding BRIDGE LIVE Rx with each SDI signal in lockstep with each other.

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 (and/or BRIDGE LIVE 3G-8) systems can be receiving SDI and sending to multiple BRIDGE LIVE systems outputting SDI, all in synchronicity. HDR is also supported, for end-to-end SDI workflows.

One-to-One HD
One BRIDGE LIVE3G-8 in Tx mode (acting as SDI encoder), and one BRIDGE LIVE 3G-8 in Rx mode (acting as SDI decoder) can preserve end-to-end synchronicity between up to 8x HD sources.

Many-to-Many UltraHD
2x BRIDGE LIVE 3G-8 in Tx mode units sending to 4x BRIDGE LIVE in Rx mode units can preserve synchronicity across 16x HD.

f deploying a Many-to-Many scenario, a common reference/genlock must be used and supplied to all of the BRIDGE LIVE encoding/Tx systems (and the associated SDI source equipment). Similarly, a common reference/genlock must be used and supplied to all the BRIDGE LIVE decoding/Rx systems (and the associated SDI destination equipment).

One-to-Many HD
One BRIDGE LIVE 3G-8 operating as Tx (Transmit, SDI encoder) and two or more BRIDGE LIVEs as Rx (Receive, SDI decoders) can preserve end-to-end synchronici
