AJA OpenGear - Actualización

Die NUR openGear OG-Hi5-4K-Plus, OG-HA5-4K, OG-4K2HD and OG-12GM cards have received a firmware update that gives them Dolby Audio and BT.2020 support, among other benefits.

Wachsende Verbraucherakzeptanz von Dolby Atmos sound systems has driven greater use of immersive audio technology in the field. As audio is processed and rendered between equipment, data loss is a risk, however, thanks to the latest v1.6.1 update, the OG-Hi5-4K-Plus behält den eingebetteten Audio-Pass-Through bei Dolby Digital und Dolby DigitalPlus compressed audio, including DD+ Atmos immersive sound. This allows professionals to control and validate that the immersive audio being produced reaches the end viewers.

Andererseits, HDR is rapidly evolving into a production standard, requiring more metadata to be transported from SDR and HDR equipment throughout the chain. New firmware versions of the AJA openGear cards reduce the potential for colour and brightness errors to occur during this process through the new VPID-Metadaten pass-through for each openGear card with optional override functionality. By automating the HDR metadata pass-through, the new enhancement makes it easier for upstream equipment to generate HDR metadata and pass it on to downstream equipment, without having to manually strip or configure it along the way.

Unterstützung für BT.2020

In addition to these enhancements, the AJA openGear cards receive a number of significant improvements: automatische Infoframe-Generierung; Benutzerdefinierte Erzeugung von HDMI-Metadaten and mastering display information for HDMI outputs; zusätzliche HDR-Funktionen mit Unterstützung für Farbraumkonverter für BT.2020 on the OG-Hi5-4K-Plus and OG-HA5-4K models; Dual-Link-Unterstützung für zwei 1,5G outputs on the OG-HA5-4K; and Unterstützung für zwei 6G-Eingabe- und Ausgabeformate (two 3G and two 1.5G) on the OG-12GM.

Nick Rasby, president of AJA, helps to understand the growing relevance of its openGear family: “openGear-compatible conversion technology is in high demand, as video professionals across industries look for simpler ways to produce high-end audio and visual content for remote and streaming workflows, live events, post-production, and beyond. To aid in this pursuit, we’ve extended the capabilities of our production-proven openGear cards to support the latest industry standards, including HDR, WCG and BT.2020 color spaces and Dolby Atmos.”

These new improvements are designed to help professionals keep HDR and immersive audio signals and metadata intact as they move throughout various equipment in the production chain, ultimately ensuring a more pristine viewer experience,” he adds.
