AJA - Bridge Live

News & Events at DigiBox



BRIDGE LIVE is a turnkey 1RU solution that makes it easy to move UltraHD or multi-channel HD video between uncompressed baseband SDI to/from a wide range of streaming and contribution codecs (H.265, H.264, MPEG-2 and JPEG 2000).

BRIDGE LIVE is a dependable and secure solution for transport of Ultra HD and multichannel HD video via the public internet with an assortment of codec options and secure transport protocols. Four 12G-SDI connections, which are backwards compatible with 6G/3G-SDI, bring video into Bridge Live, where Comprimato software can encode and/or decode and transcode up to four channels of 1080 60p HD simultaneously or one channel of UltraHD 60p.

Supported codecs include H.264 (AVC, MPEG-4), H.265 (HEVC) and MPEG-2, with JPEG 2000 (VSF TR01) available as an add-on. SRT with encryption ensures secure and reliable video streams across networks or the public internet. A range of additional supported transport containers and protocols, include RTMPS, RTP, UDP and MPEG-TS, with adaptive bit rate (ABR) ladder profiles and hand-off for OTT packaging. You can set and forget Bridge Live and it will continue to work in the background, converting uncompressed video to and from live compressed streams. The low-profile (1RU) box is easily rack mountable at your facility, in your truck or fly pack. Metadata and closed captioning are supported, as well as ad insertion markers, embedding closed captioning and subtitles, metadata pass-through, MPEG-2 ancillary packet support and electronic program guide on input.

The partnership of Comprimato and AJA brings together dynamic encoding, decoding and transcoding software with battle-tested I/O hardware for a powerful end-to-end production and delivery system. Whether streaming to Twitch or YouTube, or feeding video across your facility or to your facility across the country, BRIDGE LIVE is the solution.


Live Direct-to-Audience Streaming

BRIDGE LIVE offers a comprehensive platform for live video streaming. Streaming support includes SRT, RTMP/S (output only), 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.

Reference for remote collaboration

Reference Video for Remote Collaboration

Production and Post: Connecting remote artists and clients using reference quality video, or providing a high quality window into production for those who cannot be on-set.

BRIDGE LIVE means the flexibility to leave media and equipment at the secure, managed facility, and have creative talent work together remotely with reference quality video.

BRIDGE LIVE compliments existing GUI driving technologies (e.g. RDP, Teradici) by layering on the reference quality video needed for creative confidence and client/executive sign-off. Choices between H.265 (4:2:0, 10-bit), H.264 (4:2:2, 10-bit) with turnkey BRIDGE LIVE, or via optional license JPEG 2000 (4:2:2, 10-bit), mean there is choice and flexibility in how to approach your needs in terms of quality and latency.

Encoding For Remote Production

BRIDGE LIVE also offers the flexibility to tap video from on-set recording devices and stream the output of cameras (over a secure private line with encryption) providing a high quality window into production for those who cannot be on-set.

remote video transport

Remote Video Transport and Contribution

For Broadcast, BRIDGE LIVE provides an efficient mechanism for backhauling remote live SDI video sources to the media production facility, in order to be converted back to SDI and made available on the internal facility SDI router for ongoing production/transmission.

Traditional secure lines for remote production can be very expensive, with additional fees being levied for time before and after a production starts and ends. BRIDGE LIVE allows source cameras and local program out to be transported using publicly available internet, with no penalty for early or extended use during a production. BRIDGE LIVE also offers lower latency than traditional secure lines for time critical productions.

BRIDGE LIVE supports a flexible array of containers and protocols, including SRT, RTMP/S, RTP, UDP and MPEG-TS, and extends to Adaptive Bitrate (ABR) ladder profiles and hand off for OTT packaging. Combining AJA’s production proven I/O technology with Comprimato’s powerful encoding/decoding/transcoding software, this new gateway solution provides high-quality, cost-effective video processing, with SDI encode or decode for one channel of UltraHD up to 60p, or up to four channels of 1080 60p HD simultaneously, via four 12G-SDI connections that are also backwards compatible to 6G, 3G, and 1.5G SDI. A plug-and-play device featuring deep metadata support, BRIDGE LIVE suits a range of professional and enterprise-level video workflows with a 1RU profile that fits seamlessly into facility racks, production trucks and flyplacks. AJA also offers the option of a perpetual BRIDGE LIVE license for encoding/decoding of pristine JPEG 2000 VSF TR-01. 

Versatile by design, BRIDGE LIVE meets the rigorous live video production and delivery demands of Telco, IPTV, and cable operations, broadcast facilities and OB trucks, sports arenas, houses of worship, and beyond. Its intuitive interface helps professionals seamlessly mesh HD/UltraHD SDI and streaming/IP for live workflows using AVC, HEVC, and MPEG 2, as well as JPEG 2000 with an additional license. BRIDGE LIVE can be used as a “set and forget” resource, working in the background to convert baseband video to and from live compressed streams, including multiple stream outputs and destinations from SDI inputs. BRIDGE LIVE also supports a wide variety of audio stream and codec choices from AAC to uncompressed PCM, with the ability to apply gain and sample rate conversion and remap channels. 

Providing advanced flexibility, BRIDGE LIVE supports a host of protocols and configuration/ monitoring options for remote workflows including REST API and SNMP. Built-in 10GigE network ports provide plenty of bandwidth to move multiple streams of HD or UltraHD, and with the reliability of SRT as standard, neither public internet nor unreliable networks will prove an issue. Comprehensive metadata coverage includes support for closed captioning and ad insertion markers, as well as the ability to embed subtitles. BRIDGE LIVE makes it easy to deliver powerful results, whether streaming to a platform like YouTube, Facebook or Twitch; encoding produced video for distribution to OTT packaging; providing the video output from facility equipment to artists and clients for remote collaboration; or transporting/contributing video feeds from remote locations to a data center or media facility.
