Shaping multimedia stream bit-rates to adapt to network conditions

摘要

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.

主权项

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; determining if the bandwidth has changed by at least a predetermined amount for a predetermined amount of time; and responsive to determining that the bandwidth has changed by at least the predetermined amount for the predetermined amount of time, at an intermediate point between the source and the 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.
