Quadratic Curve Based Buffer Management for H.264/AVC Rate Control

摘要：

Buffer management is an essential element in rate control to regulate the behavior of the virtual output buffer of video encoder. In this paper, a novel quadratic curve based buffer management (QCBM) method for H.264/AVC rate control is proposed. This method considers the features of video coding and employs a quadratic curve, which is obtained according to the initial buffer fullness, target buffer fullness and the length of a group of pictures, to determine the frame layer target buffer fullness for the current coding frame. Consequently, the Pframes closer to the reference I-frame of the group of pictures would have more target bits and higher coding qualities, which leads to improvement of the performance of video encoder. Experimental results demonstrate that using the proposed buffer management method, a better rate-distortion performance can be achieved than that using the original H.264/AVC rate control.Begin the wo lines below author names and addresses.
