the "Server: field, which can be used to identify some special-case servers that are not 100% standards-compliant.
We use this to identify Windows Media Server, which has a value "WMServer/v.e.r.sion", where version is a sequence of digits (e.g. 126.96.36.19972). Helix/Real servers use something like "Helix [..] Server Version v.e.r.sion (platform) (RealServer compatible)" or "RealServer Version v.e.r.sion (platform)", where platform is the output of $uname -msr | sed 's/ /-/g'.
The "timeout" comes as part of the server response to the "SETUP" command, in the "Session: <xyz>[;timeout=<value>]" line.
It is the time, in seconds, that the server will go without traffic over the RTSP/TCP connection before it closes the connection. To prevent this, sent dummy requests (e.g. OPTIONS) with intervals smaller than this value.
