The optimal choice of encoding parameters for MPEG-4 AAC streamed over wireless networks

摘要

This paper addresses a novel linear programming based approach to optimize the choice of the encoding parameters for the MPEG-4 AAC audio codec. Current techniques solve the encoding problem for MPEG-4 AAC by splitting the encoding procedure into a sequence of smaller problems that are solved heuristically. In contrast, we approach the coding problem as multidimensional optimization problem and achieve large performance gains compared with current methods.
