The HDNetwork has a particular means of formatting VOD stream names. To assist player builder who are constructing their
own VOD IMBROBjects to hand to HDNetStream to play, this class has a single method format() which will accept a HDMBRObject and return
the same object with the internal stream names correctly fotmatted for use with the HDNetwork.
Example usage:
var myHDMBRObject:HDMBROBject = new HDMBROBject();
.... // populate the object with your stream and bitrate pairs
myHDMBRObject = HDMBROBjectFormatter.format(myHDMBRObject);
myHDNetStreamInstance.play(myHDMBRObject);
Note - this class must NOT be used to format LIVE stream names, which do not require this formatting function.
