Patent ID: 8351762

Claim:
A buffer-based adaptive media playout method in a receiver side of a network media streaming system, the method comprising: calculating a playout interval for playing out a current j-th frame (where j is a natural number) of a received media stream; and playing out the current j-th frame after the calculated playout interval has elapsed from the reception of the current j-th frame, wherein the calculating of the playout interval for playing out the current j-th frame of the received media stream includes: calculating a buffer level of a (j+w)-th frame (where w is a natural number); predicting a playout pause or a playout skip of the current j-th frame on the basis of the calculated buffer level; and calculating the playout interval for playing out the current j-th frame on the basis of a play out rate control parameter for the predicted one of the playout pause and the playout skip, wherein, in the calculating of the buffer level of the (j+w)-th frame, a weight is applied to an average reception rate of the media stream and a reception rate between the playout time of a (j−1)-th frame and the playout time of a (j−2)-th frame to calculate the predicted reception rate.
