Controlling Bit-Rates for Media Streaming Sessions

An apparatus comprising:

• a network input/output;
• a processor, and
• a memory in communication with the processor, the memory including instructions executable by the processor to perform the following operations:
• a first operation that analyzes data received through the network input/output to calculate an average packet delay trend for a media streaming session and a jitter trend for the media streaming session;
• a second operation that calculates a quantified up-speed or down-speed value in response average packet delay trend and the jitter trend;
• and
• a third operation that controls a bit-rate of the media streaming session according to the quantified up-speed or down-speed value.

Logic encoded in one or more tangible media for execution and when executed operable to:

• (a) calculate whether an average packet delay in a media streaming session is moving lower or higher;
• (b) calculate whether a jitter in the media streaming session is improving or worsening;
• (c) store a record of historical values for jitter and average packet delay and historical values for streaming bit-rate correlated with respective historical values for jitter and average packet delay;
• (d) in response to (a) and (b), calculate a difference between a current streaming bit-rate and a specific one of the historical values for streaming bit-rate to generate an up-speed or down-speed value;
• and
• (e) control a bit-rate of the media streaming session according to the up-speed or down-speed value.
