A new H.264 fast inter-mode decision algorithm based on coded block patterns is presented. Compared to the exhaustive mode search, the proposed method achieves an average 57 % reduction in computation time with negligible degradation in visual quality. The speed and rate-distortion performance is comparable to known fast algorithms that involve more elaborate mechanisms.
