By default, Advanced Fast Start is turned off in
Windows Media Services. When Advanced Fast Start is turned off, the
startup process is the same as for Windows Media Player
9 Series or later. The content does not play until the client
buffer is filled according to the Network buffering setting
in the Player.
When a client connects to a publishing point
with Advanced Fast Start turned on, Advanced Fast Start manages the
startup process. For example, if a publishing point sources from a
folder, all files in the folder will use Advanced Fast Start.
Advanced Fast Start works with the HTTP and RTSP
protocols, and can only be used with single-bit-rate streams.
Advanced Fast Start is only used by clients that
connect to a unicast stream. For the broadcast publishing points on
your Windows Media server, you may choose to allow unicast
rollover, which ensures that clients that cannot access the
multicast stream can still receive the content by switching to an
available unicast stream. You can configure Advanced Fast Start for
unicast rollover connections on the Properties tab of your
broadcast publishing points. Enabling this property does not enable
Advanced Fast Start for multicast client connections.
