The BRIDGE LIVE 12G-4 supports the most widely used IP video compression schemes and transport protocols to solve your workflow needs. The BRIDGE LIVE family supports conversion to/from SDI to numerous IP video solutions as well as pure IP conversion and distribution workflows.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. BRIDGE LIVE 12G-4 supports up to four UHD 4K60 channels.

BRIDGE LIVE 12G-4 includes support for NDI (Network Device Interface), the high-quality, real-time, low-latency IP video standard developed by NewTek. BRIDGE LIVE can support up to four simultaneous UHD 4K60 NDI encodes/decodes 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)
• Multiple discovery servers

BRIDGE LIVE and BRIDGE LIVE 12G-4 support independent SDI source inputs and maintain their synchronous relationship 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 12G-4 supports SRT v1.5.3, enabling redundant stream support over an ISP to ensure hitless delivery of the originating source. SRT is an open-source video transport protocol and technology stack that optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best-quality live video over questionable networks.

BRIDGE LIVE 12G-4 fully supports closed captioning as well as additional metadata, including:

• UHD 4K single link, SMPTE ST 2082, 10-bit
• 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
• Line 21 Captions
• Timecode embedded within H.264 SEI messages
• Embedding closed captioning/subtitles into H.264 SEI messages
• Metadata passthrough
• Electronic Program Guide (EPG) on input

BRIDGE LIVE 12G-4 can be configured using multiple protocols to meet your workflow requirements, whether it’s low-latency or high-quality signal delivery. Supported protocols include HLS (input and output), MPEG-TS, MPTS (input), RTMP, RTMPS (output), RTP, UDP, SRT (including encryption), VSF TR-01, and VSF TR-07.

BRIDGE LIVE 12G-4 supports numerous configurations for encoding and decoding between SDI and streaming formats as standard. Multiple streams, formats, and destinations can be derived from a single SDI input. It supports various configurations using NDI, H.265 (HEVC), H.264 (AVC), and H.262 (MPEG-2).Optional JPEG XS (TR 07) and JPEG 2000 (TR-01) encode/decode licenses can be purchased separately.

A video preview feature provides a visual check, so that operators can ensure they have the correct SDI input/content for encoding. It promotes basic confidence while providing customers who cannot “go live” to check their content with added peace of mind.

The BRIDGE LIVE 12G-4 supports up to four 12G-SDI ports simultaneously for multichannel HD in a 1 RU chassis. Dual 10 GigE ports provide network connectivity, and it has dual power supplies for redundancy.
