Patent ID: 8532173

Claim:
A method of predicting video traffic, the method comprising: classifying input video traffic into a number of types of frames; estimating a probability density function (PDF) regarding a size of the frames; and predicting a size of a subsequent frame using the PDF, wherein the predicting the size of the subsequent frame, comprises calculating the size of the subsequent frame based on a difference between a predicted size of a previous frame and an actual size of the previous frame and a standard deviation of a size of a reference frame, wherein the reference frames are classified into a plurality of sections based on the size of the reference frames to define control points, and the PDF regarding the size of the reference frame is estimated using the control points, wherein the types of frames comprise an I-frame, a P-frame and a B-frame, wherein step of estimating the PDF comprises: estimating the PDF regarding a size of the I frame; estimating the PDF regarding a size of the P frame; and estimating the PDF regarding a size of the B frame.
