A Reengineering Approach of the Legacy System in the Digital Media Domain

Most digital media products are developed from legacy code with small modifications because of their characteristics such as short development lead-time and budget constraints on the cost of the product. As such, if the legacy code is repeatedly revised without considering issues of maintenance, the legacy code gradually gets harder to maintain. At such point of time, reengineering of the legacy code is needed as one of the solutions to improve maintainability. However, existing reengineering researches on embedded systems mainly focus on hardware rather than embedded software. Consequently, this paper proposes the reengineering approach to improve maintainability suitable for embedded software in the digital media domain; it consists of the reengineering process, the reengineering views, and the reengineering infrastructure, and it is applied to two projects of the digital media domain.
