Message Routing - ASCII messages provide the primary method of control and status
reporting for StreamNet. Every service has a name and optionally belongs to a zone
and / or some number of “groups”. Messages may be addressed to the service name,
room name or group name. Messages may be sent multicast (UDP) or unicast (UDP
or TCP) to any or all StreamNet-enabled devices. If required, StreamNet devices will
forward messages to ensure delivery to the service(s) addressed.
Status Reporting - StreamNet services output unsolicited reports of their state and
changes in state. Reports are in a flexible format that resembles XML. Each report
is a list of “variable=value” pairs. Status reports may be sent unicast or multicast.
In addition, a TCP client may “register” for status from one or more services and the
StreamNet device will aggregate the reports onto the one TCP connection.
4 . StreamNet PerfectPixel technology faithfully replicates video over the network to ensure
the highest quality is achieved regardless of distance from the video source. Packet
loss can always occur when distributing a video signal (even a compressed one) over
an Ethernet network which may cause the picture to appear blotchy, color shifted, or
chunks of the picture to be missing all together. PerfectPixel technology solves this
issue with both compressed and uncompressed signals over the network and is a
combination of ClearOne’s proprietary algorithms for packet delivery optimization and
error concealment algorithm, insuring reliable delivery of video data and eliminating
dropped content across the network. The result is pixel-for-pixel, high definition video
distribution with consistency of high quality images across the network, regardless of
distance.
5 . StreamNet can also distribute and deliver bit-for-bit, high performance audio including
the use of Dolby Digital® and DTS® multi channel formats for decoding by a Display,
A/V Receiver or surround sound processor.
