Abstract: The present invention provides a method for storing a streaming media file in a mobile terminal, the method comprising: starting a streaming media transmission; storing a streaming media file in the background, and marking the playback position of the streaming media file; setting the stored streaming media file as a hidden file, and/or encrypting the stored streaming media file. The present invention also provides a system for storing a streaming media file in a mobile terminal. Via the method and the system, the streaming media file can be directly stored on the mobile terminal, and can be flexibly and smoothly watched by users, without influencing the charge of operators at the same time. Thus, the copyrights of the Audio/Video (A/V) files can be protected, and the service promotion of the operators can be more beneficial.
