A method of processing digital content consistent with certain embodiments
involves receiving a signal containing the digital content, wherein the
digital content has a first encrypted sample of the digital content, the
sample being encrypted under a first encryption method, a second
encrypted sample of the digital content, the sample being encrypted under
a second encryption method, and an unencrypted portion; and decrypting
the first encrypted sample to produce a decrypted sample. This abstract
is not to be considered limiting, since other embodiments may deviate
from the features described in this abstract.
