Modern digital asset management systems face the problem of handling hundreds of thousands of media files.These include multiple versions of the same image file or image editing software document, leading to substantial disk space requirements and long transfer times to and from the clients of the system.In an attempt to reduce the used storage and transmission times, we look into encoding only the differences between two versions of the same file and use them as a substitute for further processing.This work investigates several such approaches and evaluates their benefits and limitations.The variety of different file types and their nature makes it very difficult to identify the best performing method for all file types and further improvement or combination of approaches must be sought.
