A method for processing streaming media contents is provided. The method includes: encrypting the streaming media contents and generating corresponding Entitlement Control Message (ECM) and Entitlement Management Message (EMM); and transmitting the encrypted streaming media contents, the ECM and the EMM to a terminal device, in which each I frame of the encrypted streaming media contents is segmented into multiple data packets for transmission and the ECM is transmitted during the transmission of the multiple data packets. A conditional access system and a system for processing streaming media contents are also provided. Through the above technical solutions, fuzzy screen phenomena in processing streaming media contents may be eliminated, channel-switching time or dark screen time may be reduced, and thus the user's experience may be improved.
