<h1>Blinker - UDPv4 Receiver</h1>
<p>
The UDPv4 receiver module reeceives a stream using UDP version 4 across
a network.
It supports the static and dynamic variants of the BLP, EBLP and MCUF
protocols.
</p>
<h2>Configuration</h2>
<p>
The configuration of the UDPv4 receiver module with name
<code>NAME</code> is located in the <code>udp4receivers/NAME</code>
subdirectory.
</p>
<h3>Output Stream</h3>
<p>
The file <code>outstream</code> contains the name of the stream to
write the received network stream to.
</p>
<h3>Protocol</h3>
<p>
The protocol to use is configured in the file <code>protocol</code>.
It can contain the string <code>blp</code>, <code>eblp</code> or
<code>mcuf</code> to select the BLP, EBLP or MCUF protocol respectively.
If the file is not present, all protocols are accepted.
</p>
<h3>Bind Address</h3>
<p>
The file <code>bind</code> contains the local address to bind to.
It must contain the IP address and the port, i.e. a string
<code><IP>:<port></code> (hostnames are not supported).
If the local address should be determined automatically, the file
can contain <code>0.0.0.0:0</code>.
</p>
<h3>Source address</h3>
<p>
The file <code>source</code> contains the source address
as a string <code><IP>:<port></code>
(hostnames are not supported).
<br>
If the source address file exists, only a stream from the specified
address is accepted.
Otherwise, the stream can be sent from any address.
<br>
If both the source address and the protocol are given, dynamic
stream request packets are sent to the source address.
