AJA Bridge Live 12G

The AJA Bridge Live 12G 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.

Hardware

BRIDGE LIVE supports up to 4x 3G-SDI simultaneously, or 1x 12G-SDI connections yielding 4 HD channels or 1 UltraHD channel of SDI video I/O in 1RU. Dual 10GigE Ethernet ports provide network connectivity and dual power supplies provide peace of mind.

Administration, monitoring and access to BRIDGE LIVE is supported via either network browser or local Display Port. Indirect agnostic monitoring and automation is supported via both REST API and SNMP.

Metadata and Closed Caption Support

BRIDGE LIVE fully supports both closed captioning and additional metadata which is often a neglected feature set with lower cost encoding devices.

BRIDGE LIVE supports:

• SCTE-35/SCTE-104 Ad insertion markers and conversion
• CEA-608/CEA-708 Closed Captioning including conversion
• Embedding Closed Captioning/Subtitles into H.264 SEI messages
• Metadata pass through
• MPEG-2 ancillary packet support, SMPTE 2038
• Electronic Program Guide (EPG) on input

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
• 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.

• H.265 (HEVC):
• 8-bit or 10-bit
• 4:2:0
• Up to 4 simultaneous 60p HD encodes/decodes or 1x 60p UltraHD encode/decode to/from SDI
• SRT, RTMP and MPEG-TS protocol support
• H.264 (AVC):
• 8-bit or 10-bit
• 4:2:0 or 4:2:2
• Up to 4 simultaneous 60p HD encodes/decodes or 1x 60p UltraHD encode/decode to/from SDI with an HQ option*
• SRT, RTMP and MPEG-TS protocol support
• H.262 (MPEG-2):
• 8-bit
• 4:2:0
• Up to 4 simultaneous 30p/60i HD encodes/decodes or up to 2 simultaneous 60p HD encodes/decodes to/from SDI with an HQ option
• SRT, RTMP and MPEG-TS protocol support

*H.264 HQ selection limited to 30p maximum for HD and UltraHD

Live Direct-to-Audience Streaming

BRIDGE LIVE offers a comprehensive platform for live video streaming. Streaming support includes SRT, RTMP/S, RTP/UDP, and MPEG-TS. Using these standard protocols provides wide support for streaming services from Twitch, YouTube Live and Facebook Live. BRIDGE LIVE builds upon the tried and tested approach of AJA’s HELO streaming device, while including flexibility for multiple inputs, broad format and bit-rate support, as well as metadata and redundancy.

And, while streaming to CDNs for a direct-to-audience delivery, BRIDGE LIVE can simultaneously deliver different stream types to partners to re-transmit, transcode, or store.
