Typically, real-time software implementation requires omission of most optional encoding tools leading to significantly reduced coding efficiency. This paper proposes a novel method for real-time H.264 encoding based on dynamic control of the encoding parameters to meet real-time constraints while minimizing coding efficiency loss. Experimental results show that the method provides up to 19% lower bit rate than conventional real-time encoding using fixed parameters with the same visual quality. The method allows real-time 30fps QCIF encoding on a Pentium IV with similar coding efficiency to full search baseline profile encoding.||Type of material:||Conference Publication||Publisher:||Association for Computing Machinery||Copyright (published version):||2007 ACM||Keywords:||Algorithms;Design;H.264;Fast mode decision;Complexity scaling;Real-time video encoding||DOI:||10.1145/1291233.1291444||Language:||en||Status of Item:||Peer reviewed||Conference Details:||MULTIMEDIA '07, Proceedings of the 15th International Conference on Multimedia, Augsburg, Germany, 23 - 28 September, 2007|
