Overview of the VNS104
The VNS104 Multi-Stream Decoder Software application allows decoding up to four
simultaneous PURE3 video streams from VN-Matrix 200/225 Series and VN-Matrix300
Series encoders and PURE3 recorded streams in active playback on the network.
PURE3 streams contain video information compressed by the PURE3 codec and used
to transport media signals in real time over an Ethernet network. In addition, a PURE3
stream may contain associated audio content.
NOTE: The VNS104 Multi-Stream Decoding Software will not correctly display
interlaced source images.
The PURE3 codec preserves three performance factors that affect the delivery of video
over a network:
• Low latency
• Low bandwidth
• High image quality
The VNS104 software is a Microsoft
®
Windows
®
-based PC application installed on a
Windows-based PC. Each VNS104 installation requires a unique device ID and license.
These are supplied with the VNS104 and entered as part of the installation process.
NOTE: Only one instance of each VNS104 device ID is allowed on a system.
