MEAN ABSOLUTE DIFFERENCE PREDICTION FOR VIDEO ENCODING RATE CONTROL

摘要

Mean absolute difference (MAD) prediction for video encoding may be provided. Upon receiving a video stream comprising a plurality of quality layers, a first quantization parameter (QP) may be selected for a first frame of the video stream according to a second QP associated with a second frame and a third QP associated with a third frame. The first frame may then be encoded according to the selected first QP.

主权项

1. A computer implemented method for providing Mean Absolute Difference prediction, the method comprising:
receiving a plurality of video frames associated with a bitstream; predicting a mean absolute difference of a current frame according to a first mean absolute difference associated with an immediately previous temporal frame and a second mean absolute difference associated with a similar frame that has a similar rate distortion characteristic to the current frame; and encoding the current frame according to the predicted mean absolute difference.
