Patent ID: 8832434

Claim:
A method of scaling encrypted scalable media without decoding said encrypted scalable media, said method comprising: accessing data associated with said encrypted scalable media that identifies portions of said encrypted scalable media to combine in order to produce media that is scaled to possess a desired scalable attribute without decoding said encrypted scalable media; combining one or more of said portions of said encrypted scalable media and associated cryptographic checksums into a transmittable sequence of data; re-mapping data associated with said scalable media that identifies portions of said scalable media to combine in order to produce media that is scaled to possess a desired scalable attribute; and re-mapping data associated with said portions of said scalable media that identifies protection attributes of the encryption system used to encrypt said portions of said scalable media, wherein said one or more said portions of said encrypted scalable media and associated cryptographic checksums constitute a scaled version of said encrypted scalable media.
