Abstract:
A method for encrypting content includes using a plurality of different encryption schemes to produce encrypted content. Encryption information is provided so as to indicate which of the plurality of different encryption schemes is used on portions of the content that was encrypted. Encryption information and the encrypted content are both sent as a content stream to another device. The decryption involves using the encryption information to help control the decryption so that the correct one of a plurality of different decryption schemes is applied to the proper portions of the encrypted content.
