Ethernet AVB-standard chipset for uncompressed AV signal distribution
AptoVision (Quebec, Canada), has Ethernet AVB protocol support for its BlueRiver NT chipset, supporting its claim to be the only AVB capable chipset for distribution of uncompressed AV signals over 10GbE switches.

In addition to having an AVB-capable transport layer, the BlueRiver NT chipset delivers a complete end-to-end solution for professional audio-video (Pro-AV) applications. Such applications require long distance transmission and switching of 4K HDMI video, analogue and digital audio, RS-232, IR, GbE and USB signals while expecting plug-and-play, interoperable operation between device types, signal types and video resolutions.

In installations requiring traffic shaping and bandwidth reservation, AVB (Audio-Video Bridging) enables a platform where uncompressed video data and non-video data can be transmitted over a LAN environment with predictable performance.

“Ethernet-based platforms are poised to replace Pro-AV networks which currently rely on custom switching equipment,” said Kamran Ahmed, CEO and co-founder of AptoVision; “[AptoVision is] delivering an end-to-end AVB capable chipset supporting all Pro-AV requirements.”

Integrated into source-side AV transmitters and display-side AV receivers, the BlueRiver NT chipset transmits uncompressed Ultra-HD (4K) HDMI-video, 32 channels of audio, USB 2.0i and useful control signals over fibre or 100m Cat-x cabling using a packet-based architecture allowing the signals to be extended and switched through standard off-the-shelf (OTS) 10GbE switches. Proprietary technology to handle arbitration, source clock recovery, bandwidth management and network configuration ensures real-time, pixel for pixel, zero-frame latency transmission. The BlueRiver NT technology also supports real-time compositing to enable multi-view and video-wall applications.
