•The term “stream” refers to multimedia that is constantly received by (and normally presented to) an end-user while being delivered by a VN-Matrix encoding device.

About the VNR 100 Recorder

The VNR 100 recorder is a network appliance capable of recording PURE3 video, audio, and data streams from VN-Matrix codecs and encoders. Multiple VNR 100 units can be configured together into systems to record and play back multiple, synchronized PURE3 streams.

The recorder is able to play and control a previously recorded file while simultaneously recording a new file, with a sustained aggregate bit rate of 150 Mbps. The VNR 100 is also able to replay, with time slip, a file that is still being recorded.

One or more VNR 100 recorders can be used in a VN-Matrix system. The system must be under the control of an Extron VNM Enterprise Controller, whether the system contains a single VNR 100 recorder or multiple recorders. Controlling multiple recorder devices or channels from a single master unit allows:

•Support for common transport controls for record and playback of grouped channels.

•Support for directory and file management of grouped recordings and playback.

Multi-channel systems are facilitated by maintaining full stream synchronization of multiple recorder devices across all stream elements (video, audio, data, and whiteboard) at all playback speeds in forward and reverse directions.

The recorder uses a network storage architecture, which makes the system highly scalable and flexible.
