Description

Introducing the AJA BRIDGE LIVE 3G-8Audio Encoder/Decoder

The AJA BRIDGE LIVE 3G-8 is a bidirectional HD encoder/decoderdesigned for professional live broadcasting, REMI, contribution, and multi-channel transcoding. This rugged and reliable 1 RU rack-mountable unit supports up to eight simultaneous 3G-SDI inputs/outputs , with redundant power supplies and a three-year manufacturer’s warranty.

General and essential features

• Synchronous HD video streams : up to 8 HD channels (1080p/i, 720p, SD) via 3G-SDI, with support for 10-bit 4:2:2 formats.

• **Bidirectional Encode/Decode/Transcode : Compatible with H.264, H.265, MPEG-2, NDI, JPEG 2000 and JPEG XS, SRT, RTMP/S, HLS, RTP, UDP, MPEG-TSoffering flexibility and performance for low-latency streams.

• NDI support : encodes/decodes/transcodes up to 8×60p HD NDI or UltraHD 30p via SDI, with multiple discovery servers.

• Synchronized multi-channel transport : ensures synchronization of multiple SDI channels over IP or cloud links, HDR compatible, ideal for SDI backhaul, cloud contribution or multi-site architectures.

• Secure protocols : SRT v1.5.3 with encryption, hitless redundancy, firewall traversal, ensuring robust flows over public networks.

• Metadata, HDR, timecode, subtitles : full support for SCTE-35/104, CEA-608/708, timecode, EPG, SEI H.264 and SMPTE 2038.

• Flexible administration : Web interface, GUI via DisplayPort, REST API, SNMP.

Case studies

REMI production management with program feedback

With two BRIDGE LIVE 3G-8 units, you can receive up to 8 remote HD camera feeds via SRT or NDI, decode them to SDI locally while sending the program back to the capture site in real time, with timecode and metadata management.

Multi-site HDR network

For synchronous HDR broadcasts between multiple studios, BRIDGE LIVE 3G-8 ensures the synchronization of SDI signals via IP with HDR metadata management, guaranteeing visual and temporal consistency.

Multi-format OTT streaming

Configure SRT/RTMP/S, HLS, and MPEG-TS channels with ABR profiles for platforms like YouTube, Twitch, or Facebook Live. The device supports live transcoding to provide a low-latency version for clients and a high-quality version for archiving or broadcasting.
