A method for scrambling media data in real time solves the problems of heavy load on related devices and high requirements on their performance when multiple scrambling components scramble the same media data and scrambling associated data need be generated for each scrambling component in the related art. The method includes: acquiring scrambling associated data including an ECM and sending it to scrambling components based on the media data to be scrambled, in which the multiple components that scramble the same media data share the same scrambling associated data; the scrambling components scramble media data by using the scrambling associated data. Embodiments of the invention also solve the problem of failure to effectively scramble programs demanded by subscribers in the VOD system in the related art. In addition, embodiments of the invention disclose a system for scrambling media data.
