MPEG (Moving Picture Experts Groups) is currently standardizing Multimedia Application Format (MAF) which targets to provide simple but practical multimedia applications to the industry. One of the interesting and on-going working items of MAF activity is the so-called Music Player MAF which combines MPEG-1/2 layer III (MP3), JPEG image, and metadata into a standard format. In this paper, we propose a protection and governance mechanism to the Music Player MAF by incorporating other MPEG technology, MPEG-21 IPMP (Intellectual Property Management and Protection). We show, in this paper, use-case of the distribution and consumption of this Music Player contents, requirements, and how this protection and governance can be implemented in conjunction with the current Music Player MAF architecture and file system. With the use of MPEG-21 IPMP, the protection and governance to the content of Music Player MAF fulfils flexibility, extensibility, and granular in protection requirements.
