A complexity reduction algorithm tailored for the H.264/AVC encoder is described. It aims to alleviate the computational burden imposed by Lagrangian rate distortion optimization in the inter-mode selection process. The proposed algorithm is described as a hierarchical structure comprising three levels. Each level targets different types of macroblocks according to the complexity of the search process. Early termination of mode selection is triggered at any of the levels to avoid a full cycle of Lagrangian examination. The algorithm is evaluated using a wide range of test sequences of different classes. The results demonstrate a reduction in encoding time of at least 40%, regardless of the class of sequence. Despite the reduction in computational complexity, picture quality is maintained at all bit rates.
