AJA and Comprimato

BRIDGE LIVE represents an exciting partnership between AJA and Comprimato, both long standing industry innovators. The merging of AJA’s hardware development and video I/O expertise with Comprimato’s transcoding and internet transport know-how means customers can expect the versatility, speed and quality needed for that competitive edge. The unique fusion of company talent between AJA and Comprimato ensures that BRIDGE LIVE delivers the performance and reliability needed for live NDI, H.265 (HEVC), H.264 (AVC, MPEG-4), H.262 (MPEG-2) and JPEG 2000* encode, decode, or transcode needs.

*Full NDI, H.265, H.264, H.262 I/O functionality included with BRIDGE LIVE turnkey system, JPEG 2000 I/O license options available.

NDI Encode/Decode/Transcode

Starting with v1.12 software, BRIDGE LIVE includes support for NDI (Network Device Interface), the high-quality, real time, low latency live video standard developed by NewTek. BRIDGE LIVE can support up to 4 simultaneous 60p HD encodes/decodes or 1x 60p UltraHD encode/decode to/from SDI. 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)

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 product compatibility across software and hardware transmitters and receivers.

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.

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
• CEA-608/CEA-708 Closed Captioning
• Embedding Closed Captioning/Subtitles into H.264 SEI messages
• Metadata pass through
