German IP broadcast manufacturer Lawo has unveiled its new .edge IP video infrastructure platform at NAB Show 2022 in Las Vegas. .edge’s compact 2RU housing accommodates up to four 25/100 GbE .edge processing blades and rear I/O plates with best-in-class signal conversion density.
Each rear I/O blade provides 48 HD-BNC connectors for SD/HD/3G/UHD SDI interfacing, resulting in 192 SDI/IP conversions per 2RU. .edge provides full support for the SMPTE ST2110 suite of standards with ST2022-7 redundancy built in, providing advanced essence-based handling and ensuring seamless protection switching of audio, video and ancillary data streams in both local and wide-area network operations.
“.edge complements Lawo’s established V__matrix video processing and multiviewer solution with a hyper-density SDI/IP gateway,” explains Phil Myers, Lawo’s CTO. “It’s designed from the ground up to be a HOME-native client. It is automatically discovered and registered within our HOME network environment, and benefits from all of HOME’s next-generation management features: user access control, quarantining of unknown devices, network security, parameter tweaking and real-time health monitoring.”
.edge’s board design is unique: it doesn’t have an audio TDM bus nor a video matrix in the middle of its architecture. Video is switched on the IP packet level in one of two ways: “make before break” and “break before make.” Audio signals are switched in MBB mode using a V-fade curve for clean and quiet transitions. .edge’s local loop support allows users to route local inputs to local outputs, while the packet replication capability allows a packet received once can be used many times without additional stream management or logic operations: packets in the packet buffer are available to any SDI output.
