ABSTRACT:
An apparatus, method and a computer program for processing multimedia data is described, where the apparatus may include an input switch which may receive a plurality of transport stream packets corresponding to a plurality of digital multimedia data signals input thereto, and a packet identification (PID) filter unit which may selectively output a given set of TS packets to be demultiplexed from the received plurality of TS packets. A buffer and/or an external memory device may store at least some of the TS packets of the output given set. A conditional access/content protection (CA/CP) unit may read and decrypt the TS packets stored in the buffer, and may encrypt at least some of the decrypted TS packets for storage in the external memory device if the buffer becomes full, to prevent the TS packets to be stored in the external memory device from being copied.
