Using a StreamNet Decoder enables IP content distributed over the StreamNet network to
be played from any audio or video system. StreamNet decoders are compatible with any
modern display device and even legacy displays.
StreamNet uses a distributed architecture which allows the hardware and the processing
power to be spread out across a TCP/IP network. This leverages many of the advantages of
using TCP/IP over traditional analog systems. Traditionally, a video signal is transmitted over
long cables runs that degrade the quality of the signal and can increase the project costs by
requiring multiple cable runs per display. Using a decentralized IP based system preserves
the HD quality of the signal and saves money by requiring only one CAT5 cable for audio,
video, and control of the display.
ViewLinX Decoders fully support compressed and uncompressed video. Video may be
distributed in both compressed and uncompressed forms. Sending video uncompressed
allows the HD quality to be preserved during distribution on a gigabit network. For
installations without a gigabit network or those with many simultaneous streams, ViewLinX
fully supports compressed formats using NetStreams proprietary MotionXT™ Video
Compression. If at a later date video quality needs change, ViewLinX can be easily re-
configured to use uncompressed video.
ViewLinX supports unlimited number of displays. Using TCP/IP as a distribution method
also renders limitations on the number of display devices obsolete. TCP/IP treats each
ViewLinX as just another device on the network. By using TCP/IP multicast protocol
StreamNet easily manages all network traffic to ensure full motion and resolution is
preserved with minimal artifacts. Additionally, StreamNet technology keeps each zone
synchronized so all zones play within 500 microseconds of each other, ensuring audio and
video is always kept in sync.
ViewLinX supports both SD and HD video decoding. Each ViewLinX Decoder converts an
IP stream (compressed or uncompressed) back into SD or HD and outputs the program
material into the appropriate signal output type. All ViewLinX Decoders can output H Sync,
Vsync, Y/G/CVBS, Pb/B/C, and Pr/R signals through BNC connectors and include an HD 15
connector for VGA signals.
ViewLinX DualDrive technology can automatically determine which signal type is being used
and route the signal to the appropriate connector. This is ideal for situations where a display
must display VGA and video signals in the case of a DVD player and PC connected such
as in a corporate board room application. Dual Drive also allows both BNC and DB-15
connectors to be connected. The ViewLinX can also be programmed to switch the displays
input based on the source signal. With a ViewLinX Decoder the AV designer has maximum
