Abstract
H.264/AVC is a video codec developed by the Joint Video Team (JVT); a cooperation between the ITU-T VCEG (Video Coding Experts Group) and ISO/IEC MPEG (Moving Picture Experts Group). This new video coding standard has some new features that allow to get significant improvements in coding efficiency. This improved coding efficiency leads to an overall more complex algorithm which has high demands regarding memory usage and processing power. Complexity, however, is an abstract concept and cannot be measured in a simple manner. In this paper we present a method to obtain an accurate and more in-depth view on the internals of the JVT/AVC decoder. By decoding several bit streams having different encoding parameters, various program characteristics were measured. On these measurements, principal components analysis was performed to get a different view on these measurements. Our results show that the various encoding parameters have a clear impact on the low level behavior of the decoder. Moreover, our methodology allows us to give an explanation for the observed dissimilarities.
