Used for H.264 and MPEG4 codecs. It specifies the

CBR is useful for streaming multimedia content on

limited capacity channels since it is the maximum bit

rate that matters, not the average. Therefore, CBR

would be used to take advantage of all of the

channel capacity.

- Storage

Means Variable Bitrate Encoding (VBR) will be used.

compared to a CBR file of the same data. VBR files

HTTP streaming port

The number of the port being used to stream the HTTP

broadcast. This value would be used along with the URL

to access the broadcast. In the case when independent
