Method and system for predictive control for live streaming video/audio media

A method for processing digital video signals for live video applications, the method comprising:

• providing video data comprising a plurality of frames;
• identifying a first frame and a second frame in the frame sequences;
• processing information of the first frame and information of the second frame to determine a quantization step value for the second frame;
• and
• adjusting a transmission bit rate for the second frame in response to the quantization step value,
• wherein the processing the information of the first frame and the information of the second frame comprises:
• calculating a sigmaSAD value for the second frame;
• calculating a divisor value for the second frame;
• and
• calculating the quantization step value for the second frame;
• wherein the calculating the quantization step value comprises setting the quantization step value equal to the sum of the ratio of the sigmaSAD value to the divisor value and a constant equal to 1.
