An Efficient Traffic Smoothing Method for MPEG–4 Part–10 AVC/H.264 Bitstream over Wireless Network

摘要

In this paper, we propose an efficient traffic smoothing method for MPEG–4 Part–10 AVC/H.264 bitstream over wireless network. In general, the conventional traffic smoothing schemes try to reduce network congestion, however the main target of the proposed method is to reduce artifacts such as frame skip, occurred at the receiver. The proposed method consists of packet-based windowing and probing method. It can be efficiently applicable to the slice structure of H.264, and reduce computation complexity. In our experimental results, the proposed method shows promising results, which maximizes the degree of traffic smoothing and minimizes the frame skip count of receiver adaptively.
