Abstract:
An apparatus for encrypting and recording a broadcasting program includes a packet input unit configured to receive packets of a broadcasting program to be recorded and sequentially output the packets, an encryption selector configured to receive the packets sequentially output from the packet input unit, selectively output the received packets to a first path and to a second path, wherein packets to be encrypted are output to the first path and packets not to be encrypted are output to the second path, an encryption processor configured to encrypt the packets output to the first path based on a predetermined encryption method, and a storing unit configured to store the encrypted packets from the encryption processor or store the packets output to the second path.
