Windows Media Player 9 Series or later contains improvements that add efficiencies to the network connection process and minimize startup latency. This allows you to add a URL modifier that specifies the minimum buffer time to the path of a multicast stream. The URL modifier specifies a value for the Network Buffer Time property. The property value is the amount of time in milliseconds (ms) that the Player will buffer before playing the multicast stream. To specify the minimum buffer time for a multicast, add the following modifier to the multicast information (.nsc) file URL:
For example, the following multicast URL uses a modifier that sets buffer time to 500 ms.
Network Buffer Time=0x000001F4
In this example,
0x000001F4 is a
hexadecimal value that sets the buffer time to 500 ms.
