1. A method comprising:
- monitoring a condition indicative of a bandwidth of a network path on which a multimedia stream is being sent from a source to a destination; and
at an intermediate point between the source and destination on the network path of the multimedia stream, adjusting a transmit bit-rate of the multimedia stream to adapt to the condition indicative of the bandwidth of the network path.

Abstract
An apparatus and methods are provided for shaping a transmit bit-rate of a multimedia stream to adapt to the bandwidth of network path on which the multimedia stream is sent between a source and destination. A condition indicative of a bandwidth of the network path is monitored, and at an intermediate point on the network path between the source and destination, the transmit bit-rate of the multimedia stream is adjusted to adapt to the condition indicative of the bandwidth of the path.
