Transmit Proxy
The QVidium QVARQ QoS Proxy Server consists of 4 transmit proxy modules and 4 receive
proxy modules. Each of these modules are independent of each other can be operated in any
combination.
Should your application require more than the available number of modules, please contact
QVidium Technologies, Inc. We also offer an unlimited version of the proxy server, without a web
interface, that may be more appropriate for your application. The unlimited version is configured
through a Linux shell script.
2.1 Transmit Proxy Overview
The transmit module of the QVidium QVARQ QoS Proxy Server is configured and operated from the
web browser. This section explains how to configure the server’s transmit parameters. The
configuration involves setting a few basic network parameters. There are no specific parameters
involving error correction or the other QoS technologies, since they are all automatically applied to
the outgoing stream.
From the web interface, you can configure any or all of the four transmit modules in the QVARQ
QoS Proxy Server. Each module, when registered with its own license key, operates and is
configured as an independent unit, and can process a separate media stream. If you need more
than four different simultaneous programs, then please contact QVidium Technologies for
information of the unlimited version of this technology.
2.2 Transmit Proxy Configuration
1. Enter http://IPAddress where IPAddress is the IP address of the QVidium QVARQ
QoS Multimedia Proxy Server™. (The default address is http://192.168.1.31.)
2. Click on “Profile” under one of the 4 “TX Proxy” items from the menu on the left. The “TX
Proxy Profile ” interface should display in the main area to the right of the menu system,
as shown in Figure 1. NOTE: You can only configure a TX Proxy module that has been
registered with a valid license. If uncertain about the license state, please click on
“Register”. To obtain a license key that you have purchased, please e-mail QVidium at
[email protected] with the 32-digit license code. Without this code we cannot issue you a
license key.
3. On the transmit profile configuration page, enter the source UDP port to match the UDP port
of the incoming IP media stream. If the source media stream does not have RTP
encapsulation, but instead encapsulates the MPEG2 Transport Stream as the raw payload of
UDP packets, check “Source UDP Only”. If the incoming stream does not have ARQ and
is a multicast stream, then additionally, you must enter the multicast IP address. If you are
receiving a unicast IP stream that was directly only to this server, please leave the multicast
address field blank.
4. You will also have to choose a destination IP address and UDP port number, for the
replicated output streams. The ARQ port and the destination UDP media port should be
different values.
