Q-SYS AV Bridging

The Q-SYS AV Bridging feature expands the functionality of the NV-21-HU, allowing users to connect their devices via USB-C directly to the network video endpoint to integrate Q-SYS audio and camera feeds for remote meetings easily. The NV-21-HU emulates a webcam (for video streams from Q-SYS network cameras), a speakerphone, and a multichannel soundcard over a single driverless USB connection.

Audio

HDMI Audio Input

Receive up to 8 channels of PCM audio from your video source, which are routable within Q-SYS Designer Software.

USB-C Audio Input

Receive up to 8 channels of PCM Audio from your video source, which are routable within Q-SYS Designer. Additional 1x1 Speakerphone and 2x2 Soundcard options are available with the Q-SYS AV Bridging feature.

HDMI Audio Output

Embed up to 8 channels of PCM audio from Q-SYS to the HDMI output of the NV-21-HU to utilize the built-in speakers of a display as a Q-SYS audio destination for source audio content or any other audio, including paging, background music, etc.

AES-128

NV Series supports AES-128 encryption for audio and video signals from encoders to decoders.

Content Protection

HDCP 1.4 & HDCP 2.3 complaint

802.1x

802.1x authentication is available and configurable through Q-SYS Peripheral Manager.

The NV-21-HU uses Q-SYS Shift™ video compression to provide high-quality, low-latency video streaming supporting video formats up to 4k60 4:4:4 over a standard gigabit network. Q-SYS Shift™ leverages DCT and temporal compression technologies, much like those found in H.264 and H.265 video compression codecs. Q-SYS optimized Shift™ to provide flawless image quality from the most demanding content sources. Further, Shift™ intelligently manages and optimizes the resulting network bitrate by only refreshing changes within each frame, allowing for significantly reduced bandwidth usage as compared to other compression codecs.

Note: We do not support 4k60 without Display Stream Compression (DSC) or reduced blanking.

Scaler

The NV-21-HU features a robust 4K60 4:4:4 scaler that can accommodate the most challenging resolution and frame rate conversions from network streams or local HDMI and USB-C sources. The scaler is capable of operating in three modes (configurable within Q-SYS Designer Software):

• Stretch-to-fit
• Maintain aspect ratio
• 1:1 pixel mapping
