Configuration: Encoder > Video
The WM appliance supports multiple bit rate (MBR) whereby several streams are encoded at
different bit rates. In this encoding strategy, the Windows Media Player negotiates with the
appliance (or with a Windows Media Server) to select and play the stream that is most
appropriate for current bandwidth conditions. Many of the configuration settings in this
section are MBR-specific. For more about MBR, see Using Multiple Bit Rate Streams on
page 8. Note that you can over subscribe the WM appliance by configuring multiple video
rates using resolutions and frame rates and/or bit rates that are too high. The exact
combinations that are too high will vary depending on the video content you are encoding.
Monitor the Status: Encoder Status page for
the encoder is over subscribed.
Note Any change in the configuration settings for any of the video encoders will cause a
brief interruption of video and audio for all three encoders. All streams being sent
from the unit (including multicast and push) are interrupted. Any active HTTP or
RSTP clients will be dropped and any archive file in progress will be closed.
