The advanced video coding (AVC) standard H.264 achieves better video compression performance compared with the previous standards, and one of major features is variable block sizes based mode decision (MD). However, the computational complexity is one key challenge for the high efficient compression. Taking into consideration the statistical characteristics and the adaptive adjustment, a fast Inter MD algorithm is proposed in this paper. The proposed MD algorithm is effective, and it is easy to implement. The simulation results show that the new algorithm reduces 20% processing time on average. Mostly, the losses of video are around 0.02dB, and the increase of bitrate can be limited less than 1%.
