Model Predictive Control Approach for
Optimal Bitrate Adaptation
Principles of MPC
• Model Predictive Control (MPC) is a multivariable control algorithm
that uses:
• an internal dynamic model of the process
• a history of past control moves and
• an optimization cost function J over the receding prediction horizon,
to calculate the optimum control moves.
