VBrick Systems VB5000, VB6000, VB4000 manual MBR Output Settings, Http/Rtsp

Output	Description
HTTP/RTSP	Unicast streams are provided via the VBrick internal server. In order to use
Unicast	this feature, you first create up to three groups, each of which consists of an
	audio stream at a selected rate and video stream at a selected rate, and
	optionally closed captioning and metadata. Some or all of these groups are
	Enabled on the Configuration: Encoder > Server page. The end-user client
	then determines whether to pull a specific group from the server or to
	negotiate with the server in order to pull the best quality stream based on
	available network bandwidth. To allow the player/server negotiation, you can
	open a Windows Media Player and enter the HTTP URL shown on the Server
	page, for example http://172.22.173.10:8080/vbrickvideo1. Alternately,
	you can request a specific group by appending a known group number, for
	example http://172.22.173.10:8080/vbrickvideo1/group1.

Note The WM appliance reflector feature does not currently support multiple bit rates. If the source of a push/pull to a reflector contains multiple video and/or audio streams, the reflector will reflect the entire stream with all video and audio included. This is only useful if there is a Microsoft Windows Media Server downstream from the reflector.

MBR Output Settings

The three concurrent video encoders all use the same video input. The following table shows the configuration output settings that are shared between all video encoders, and the output settings that can be configured independently for each one. See Configuration: Encoder > Video on page 24 for more details.
