According to one embodiment, a digital TV tuner module (204) receives digital broadcast program data including encrypted program contents. A descrambler (413) decrypts the program contents included in the received digital broadcast program data. A encryption unit (507) encrypts the decrypted program contents by an encryption key and outputs the encrypted program contents onto a PCI bus. A revocation information storage unit (502b) stores revocation information indicating that an information processing apparatus (10) is revoked. Revocation circuits (800, 900, 940, 920, A10, A20, A30) prevents any one of a plurality of devices (4, 110, 111, 113-116) from redistributing program contents outside the information processing apparatus (10) in accordance with the revocation information stored in the storage unit (502b). |
