<p>
- Vlc stands for VideoLAN client. It is the name of the program which is
- capable of decoding MPEG streams, and displaying them onto your screen,
- so you can watch you favourite movies, confortably sit in your armchair
- :-).
+ VideoLAN is a complete software solution for video streaming, developed
+ by students at the <htmlurl url="http://www.ecp.fr" name="Ecole Centrale
+ Paris"> and contributors from all over the world, under the General
+ Public License (GPL). It has been designed for streaming MPEG 1 and MPEG
+ 2 videos on local area networks (LAN), but it can be extended to
+ metropolitan or wide area networks (MAN, WAN),
+ thanks to the multicast technology.
+ The VideoLAN solution includes a server, which can stream video from
+ various sources (file, DVD, satellite, camera, ...), a client, which can
+ receive, decode and display MPEG 1 and MPEG 2 streams and, if necessary,
+ a channel server which tells automatically to the client the parameters
+ needed to receive the stream.
