摘要：Recently, with accessible media, tools, and applications, a user has been able to create multimedia files without professional knowledge. A wide variety of multimedia file formats are available to meet different requirements. From the perspective of digital preservation and version management, however, most existing multimedia file formats have several shortcomings. For instance, there is no support for recovering damaged multimedia files using their derived files or a systematic comparison of content among derived files. In this paper, we propose a method to preserve multimedia files in such a way that individual files maintain preservation information along with multimedia data to keep track of change history. In order to show the feasibility of our approach, we extend the ISO base media file format on which various well-known media formats such as MP4 are based and analyze our approach in terms of storage consumption.
