All things related to multicast

One further note on the topic: Beside setting TOS bits correctly and
hopeing for the network to be appropriately diffserv configured and/or
adding FEC to the stream:

  There's also a lot a decoder can do to simply hide packet loss artefacts
  from the user and thus reduce the visual impact of it. As someone else
  said on this thread: It is extremely lame to display green blobs wherever
  some packet loss occured (unless may you set the -DEBUG_PACKET_LOSS switch
  on the product ;-) - you can always display the previous frames content
  at this place. Beyond this, one can try to interpolate a picture or parts
  of it that are missing from neighboring pictures and this should especially
  be attractive for MPEG[124] codecs, because they already use motion vectors,
  so if for example you loose all or parts of an P or B frame, you can 
recreate
  it by actually interpolating the motion vectors and thereby re-creating 
  the missing picture(parts) again so that it it does not create any
  frozen picture artefacts, and with a bit of luck you hide the packet loss
  completely from an untrained eye.

Cheers
