- 6. The method of claim 5, wherein the server, responding to the request, retrieves the capability parameter from the capability exchange server via the capability exchange mechanism for adjusting the packet data rate.
- 7. The method of claim 6, further comprising
the server adjusts the packet data rate based on capability parameter in order to conform to the maximum data rate capability at the client.
- 8. The method of claim 1, wherein the message is signaled to the server via a multimedia streaming control protocol.
