NAME

       pob-fec - receive FEC MP3 streams

SYNOPSIS

       pob-fec [ -s address ] [ -p port ] [ -b size ] [ -q ]

DESCRIPTION

       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.

OPTIONS

       -s address
	      Specify the address to listen to (default 224.0.1.23). If the address is a multicast address, group membership is requested automat-
	      ically.

       -p port
	      Specify the port to listen to.

       -b size
	      Specify the number of ADU groups that are hold in the buffer (default 16).

       -q     Don't output any information on standard error.

EXAMPLES

       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.
