Problems solved by technology

However, the file that only contains the descriptive information is not enough for the user to have a real sensory experience of the content of the DRM file, and cannot arouse the user's interest, or the user cannot yet have sufficient knowledge and understanding of the described media object. It may cause the user to download the DRM file that he is not interested in.
