Multiple bit rate video creates multiple video streams within one encoded .asf file or ASF stream. The video streams are encoded at different target network bandwidths. For example, if you choose a multiple bit rate video template that specifies a target bandwidth of 56 kilobits per second (Kbps), video streams will be created that use greater and lesser amounts of the available bandwidth, but it will not make the content accessible by users with a 28.8 Kbps network connection. To supply content to users with 28.8 Kbps connections, choose a template that lists both target networks or create a custom configuration.
When you create a custom configuration with multiple bit rate video, you can have up to five different video streams in one ASF stream or file. The available network bandwidth ranges from 28.8 Kbps to 300 Kbps.
Using multiple bit rate video allows Microsoft Windows Media Player to continue rendering content when network bandwidth is reduced. If there is a reduction in the amount of network bandwidth available for the ASF stream during the playback, the stream will use the lower bandwidth option. The user will experience a slightly lower quality stream during the time when the bandwidth is reduced, but the stream will not be interrupted or need to be buffered to recover from the loss of bandwidth. It also allows a single piece of content to be viewed by many different users.
