VBrick Systems VB5000, VB6000 Pulling MBR Streams, Pulling VOD Files from a Microsoft WM Server

		WM Configuration
Mode †	On	Live streams – the pull receiver continuously pulls a live
		stream (if available) from the configured source.
		Stored streams – the pull receiver plays the same VOD file
		over and over. Any clients tuning in join the stream in
		progress. Note that even though the reflector will automatically
		restart the pull of a stored file, the client player must be manually
		restarted at file end.
	Off	The Pull receiver is off and will not pull any live streams or
		stored files.
	On with	Live streams – a pull starts when the first client connects.
	Bandwidth	Any additional clients tuning in join the stream in progress.
	Save	The pull stops when the last client disconnects.
		Stored streams – a pull starts when the first client connects.
		The file plays from the beginning and stops at the end. Any
		additional clients tuning in join the stream in progress. If all
		clients disconnect before end of file, the pull stops and the
		next client initiates a pull from the beginning.
		Note: It is not useful to have multicast enabled and the Mode
		set to Bandwidth Save because the active multicast destination
		will act like a perpetually active client and will never allow the
		Pull feature to pause to wait for a client to connect. For best
		results, if multicast is enabled, set the Mode to On.
Authentication	Check to enable. If enabled you are prompted for User Name, Password,
	and Domain. Authentication may be required by a Microsoft WM server.
	Streams pulled from a VBrick reflector or a VBrick encoder do not require
	authentication.
User Name	User name for the publishing point on a Microsoft WM server.
Password	Password for the publishing point a on Microsoft WM server.
Domain	The domain on which the Microsoft WM server should authenticate.

†In the context of Pull Receiver Mode, "clients" are multicast destinations, server clients (HTTP and RTSP), push destinations, and archiver.

Pulling MBR Streams

The Pull option does not distinguish between individual MBR streams and will request all streams from the source—effectively pulling the aggregate MBR set. The bandwidth required to pull the stream is the total rate for the aggregate stream and may be considerable. To reduce bandwidth usage, you can configure the URL to pull specific groups from a VBrick WM Appliance to select specific MBR combinations resulting in a single streams. This is not an option when pulling from Microsoft servers and encoders.

Pulling VOD Files from a Microsoft WM Server

Live or stored streams can be pulled from a Microsoft WM Server. There is no fast caching for buffering because the reflector does not support buffering. The pull feature of VOD streams does not support FF, REW, or seek functions. The reflector pull does not support server-side play lists, FTP download, HTTP download, or VOD files from a WM Appliance VBStar.
