Extron VNC-325, 3G-SDI codec over IP networks for demanding AV applications

The VNC-325 codec from Extron Electronics is a solution that allows the sending of SD and HD video over IP networks with low delay and high quality.

Extron Electronics has introduced the 3G-SDI over IP codec, VNC 325 belonging to the VN-Matrix series. This computer streams SDI video, HD-SDI or 3G-SDI and embedded audio over IP networks to meet requirements for low delay and transport of production-quality SD and HD video over enterprise networks.

The VNC-325 supports embedded audio streaming that passes through four channels of synchronized audio, lossless, via auxiliary data blocks (Anc). Up to four blocks of ANC data can be streamed with video from 16 audio channels. alternatively, Two channels of audio can be streamed in stereo mode providing mono, stereo or surround sound 5.1 in applications that require the use of lower bandwidth. Video can also be streamed without audio.

Two channels of audio can be streamed with video in low-bandwidth applications or up to 16 Audio channels can be heard in auxiliaries.

VNC-325 codec uses extron Pure3 codec, Wave-based compression technology that surpasses many of the performance characteristics of standards-based compression systems, Displaying visible lossless images with low latency and high immunity against network failures. Offers selectable encoding and decoding functions and video decoding with genlock from an external SDI reference. VNC-325 Pure3 codec can deliver visual lossless image quality.

The Extron VNC-325 also supports synchronized decoding of audio and video streams through multiple set-top boxes keeping the genlock and framelock even with packet loss.. This capability can be important for video from cameras or sensors with more than one output signal, Applications using multiple cameras or very high-resolution material consisting of multiple high-resolution signals.

This equipment is ideal for quality applications, such as live video streaming across a campus, Production Collaboration, Multimedia sharing study to study and contribution of original video source.

“We designed the VNC-325 with a unique combination of high quality and low delay and flexible bitrate management features to ensure an ideal solution for SDI signal transmission.. Ideal for the most demanding AV applications, as the production collaboration, Studio-to-study media sharing and the contribution of the live video source”, says Casey Hall, Vice President of Sales and Marketing at Extron.
