>Typing multicast addresses is not very fun... that's why you need
a channel information service ! VideoLAN has implemented a channel
information service based on the SAP/SDP standard. The SAP announces
about the multicast programs are sent on the network (via the multicast
address <EM
>224.2.127.254</EM
> reserved for this purpose).
On the client side, VLCs receive these annouces and automatically add
the programs announced to their playlist.</P
><P
>VLC can send the SAP announces associated with the programs
it is streaming. VLS can't do that, but an independant program, the
mini-SAP-server, can send the announces for the programs sent by
VLS.</P
