Information processor and information processing method

摘要

An information processor (S) including a processing device (1, 3) for recording information on a recording medium (DK, HD) or reproducing the information recorded on the recording medium (DK, HD), characterized in that the information processor (S) is provided with: an encrypting/decrypting device (5,6,7,8) which is capable of an encrypting operation for encrypting the information to be recorded when the information is recorded on the recording medium (DK, HD) and a decrypting operation for decrypting the information to be reproduced from the recording medium (DK, HD) when the information is reproduced from the recording medium (DK, HD), the processing device comprising the two or more encrypting/decrypting devices(5,6,7,8), a control device (12) which controls the encrypting/decrypting device so as to perform one of the encrypting operation and the decrypting operation, and a switching device (9) which switches a transmission path of the information to the encrypting/decrypting device in response to one of the operations performed by the encrypting/decrypting device. <IMAGE>
