.SH DESCRIPTION
.B pob\-fec
receives a FEC MP3 stream using a custom protocol. The streamed MP3
frames are first decomposed in autonomous data units (ADUs). These
ADUs are grouped into ADU groups, which are encoded redundantly using
a FEC method by Luigi Rizzo. For example, a group if 8 ADUs can be
encoded into 16 packets. Any 8 received packets of these 16 packets is
sufficient to recover the original 8 ADUs. The incoming MP3 stream is
decoded, buffered and written to stdout.
.SH OPTIONS
.IP "-s address"
Specify the address to listen to (default 224.0.1.23). If the address
is a multicast address, group membership is requested automatically.
.IP "-p port"
Specify the port to listen to.
.IP "-b size"
Specify the number of ADU groups that are hold in the buffer (default 16).
.IP "-q"
Don't output any information on standard error.
.SH EXAMPLES
.IP "pob-fec -s 224.0.1.24 -p 8989 | mpg123 -"
Receive the MP3 FEC stream sent to 224.0.1.24 on port 8989 and feed it
into the MP3 decoder mpg123.
