Abstract: A method for receiving contents using a mobile terminal according to the present invention is provided. The method includes generating a security channel connected to system being in charge of a service and content protection (SCP) client through an agent downloaded and installed in a mobile terminal; downloading and installing one or multiple SCP client software of different kind from the system through the security channel generated by the agent; and playing back the service or content provided in protected state by a content provider among the one or multiple SCP client software of different kind by driving the decodable SCP client software.

Abstract: Disclosed are a network protocol for contents protection in a digital cable broadcasting service and a conditional access system using the protocol. A method for renewing conditional access client software (CACS) by a conditional access module in a renewable conditional access system (RCAS) may include: receiving an RCAS announcement message from a headend; transmitting to the headend a key registration request message for requesting an authorization key when the RCAS announcement message is authenticated; receiving a key registration response message including the authorization key from the headend; and generating security factors based on the authorization key and renewing the CACS by using the security factors.

Abstract: An apparatus for combining a broadcasting channel may include a channel detector to detect a vacant Radio Frequency (RF) broadcasting channel used by a photoelectric converter that converts a first broadcast program as an optical signal to a first RF signal, a broadcast receiving interface to receive at least one second broadcast program, a broadcast modulator to generate a second RF signal by modulating the second broadcast program using the vacant RF broadcasting channel, and a channel combiner to combine a broadcasting channel used for the first RF signal and the vacant RF broadcasting channel.
