9 Years HE AAC — Technical Challenges Using an Open Standard in Real-World Applications
The technical work on creating the MPEG HE AAC standard was finished 9 years ago. Since then, the format has become very popular in specific markets and devices such as PCs and mobile phones, mainly due to its high compression efficiency. However, creating a reliable eco-system based on this open standard remains a technical challenge. In this paper, results of several compatibility tests, which were conducted over the last two years on both mobile phones and broadcast receivers, are presented. The problems encountered and the recommended solutions are described.
