BRIDGE LIVE can support up to 8x simultaneous 60p HD NDI encodes/decodes or 4x 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 offers comprehensive NDI compatibility with third-party NDI software and hardware transmitters and receivers. SRT Ready SRT is an open-source video transport protocol and technology stack that optimizes streaming performance across unpredictable networks, providing secure streams and easy firewall traversal, bringing the best quality live video over unreliable networks. The SRT Alliance is a collaborative community of industry leaders and developers dedicated to achieving 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 supports 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 fully supports Closed Captioning as well as additional metadata, which is often a neglected feature set compared to other encode/decode solutions.   BRIDGE LIVE supports: 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 Simultaneous Bidirectional Encoding and Decoding BRIDGE LIVE 12G-4 and BRIDGE LIVE 3G-8 support simultaneous bidirectional encoding and decoding from UltraHD (BRIDGE LIVE 12G-4 only), HD, and SD baseband sources. Both models support 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 12G-4, while BRIDGE LIVE 3G-8 supports up to 8x HD channels.   Synchronous Multi-Channel Transport BRIDGE LIVE supports independent SDI source inputs and maintains synchronous relationships 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.   Synchronous Multi-Channel Transport can be scaled up from a single BRIDGE LIVE pair to multiple pairs, enabling workflows where multiple BRIDGE LIVE systems can receive SDI and send SDI to multiple BRIDGE LIVE systems simultaneously. HDR is also supported for end-to-end SDI workflows. JPEG XS Encode/Decode License BRIDGE LIVE capabilities can be optionally expanded to include visually lossless JPEG XS encoding and decoding. JPEG XS (TR-07) 10-bit 4:2:2 BRIDGE LIVE 12G-4: Up to 2x 60p UltraHD, or 4x 30p UltraHD encode/decode (up to 800Mbs) BRIDGE LIVE 3G-8: Up to 8x simultaneous 60p HD encode/decode (up to 220Mbs) IP to IP transcodes with JPEG XS are supported and can be scaled up depending on CPU & GPU resource availability MPEG-TS protocol support $1,499 US MSRP per HD channel $5,499 US MSRP per UltraHD/4-channel HD JPEG 2000 Encode/Decode License BRIDGE LIVE capabilities can be optionally expanded to include high-quality JPEG 2000 encoding and decoding.

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 Site-to-Site SDI (SDI backhaul) workflows, BRIDGE LIVE’s bidirectional functionality enables it to simultaneously function as an encoder and a decoder. Consequently, references to “BRIDGE LIVE Tx” or “BRIDGE LIVE Rx” solely describe the unit’s status rather than referring to products that support only encoding or decoding, necessitating the purchase of 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 systems can receive SDI and send it to multiple BRIDGE LIVE systems outputting SDI, all in synchronicity. HDR is also supported for end-to-end SDI workflows. Many-to-Many UltraHD One BRIDGE LIVE 12G-4 unit in Tx mode, sending to one BRIDGE LIVE 12G-4 units in Rx mode, preserves synchronicity across 4x UltraHD streams. When deploying a Many-to-Many scenario, a common reference/genlock must be used and supplied to all of the BRIDGE LIVE 12G-4 encoding/Tx systems (and the associated SDI source equipment). Similarly, a common reference/genlock must be used and supplied to all the BRIDGE LIVE 12G-4 decoding/Rx systems and the associated SDI destination equipment.  Cloud Contribution with Synchronous Multi-Channel Transport BRIDGE LIVE provides an efficient and easy-to-manage approach for bridging on-site signals to and from the Cloud. Used in conjunction with instances of Comprimato Live Transcoder, BRIDGE LIVE delivers a scalable and customizable solution for modern media delivery, and the advanced codec support saves bandwidth and provides immediate distribution with minimal latency. Thanks to its flexible architecture, the solutions can be used on any cloud provider, such as AWS, Google Cloud, and Azure.   Note: AWS references are examples. Comprimato Live Transcoder can be used as the receiver with other cloud providers/services.  Contribution - Remote Video Transport  For broadcast, BRIDGE LIVE provides an efficient mechanism for backhauling remote live SDI video sources to the media production facility, where they are converted back to SDI and made available on the internal facility's SDI router for ongoing production/transmission. Traditional secure lines for remote production can be very expensive, with additional fees charged for time before and after production starts and ends. BRIDGE LIVE allows source cameras and local programs to be transported using publicly available internet, with no penalty for early or extended use during production. BRIDGE LIVE also offers lower latency than traditional secure lines for time-critical productions. REMI - BRIDGE LIVE as a Receiving Hub BRIDGE LIVE supports workflows where it is necessary to receive contribution streams from various third party encoders, IP cameras, or AJA HELO Plus for conversion to SDI at a production facility.   For example, BRIDGE LIVE could receive UDP or HLS from AJA HELO Plus, SRT from a camera or encoder, and NDI (locally) from AJA BRIDGE NDI, or software such as an NLE, an NDI camera, or a third-party hardware-based encoder. Collaboration - Reference Video for Remote Creatives Production and Post: BRIDGE LIVE connects remote artists and clients using reference-quality video, providing a high-quality window into production for those who cannot be on-site. This enables creative talent to collaborate remotely with reference-quality video, while ensuring that media and equipment are securely stored and managed at the secure facility. BRIDGE LIVE complements 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 a turnkey BRIDGE LIVE, or via optional licenses for JPEG 2000 (4:2:2, 10-bit)* and JPEG XS (4:2:2, 10-bit)*, means there is choice and flexibility in how to approach your needs in terms of quality and latency. *(JPEG 2000 and JPEG XS require an optional license available from AJA) Collaboration - Secure Window into the Remote Set or Studio 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. Collaboration - Connecting Remote NDI Production Teams BRIDGE LIVE can be used to connect two geographically separated NDI production teams via the public internet. For example, a studio or event location could send feeds from multiple NDI cameras to an NDI production or post facility, which can distribute those sources as both NDI and SDI while also returning program feedback to the studio location.  Pure IP transcode capability lets users convert between any IP codec, such as NDI to/from H.264, with SRT or H Streaming - Live Direct-to-Audience BRIDGE LIVE offers a comprehensive platform for live video streaming. Streaming support includes SRT, HLS, RTMP/S, RTP/UDP, and MPEG-TS. These standard streaming protocols provide wide support for services such as Twitch, YouTube Live, and Facebook Live. BRIDGE LIVE offers flexibility for multiple inputs, supports a broad range of formats and bit rates, as well as metadata and redundancy. BRIDGE LIVE ca
