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 ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x1288.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="x1299.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >On the client side</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Send announces when streaming with VLC</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
