A video processing device for decrypting a compressed video signal includes a key storage device for storing at least one decryption key. An decryption processing device retrieves the at least one decryption key from the key storage device, and decrypts an encrypted elementary bit stream into at least one elementary bit stream, wherein first portions of the encrypted elementary bit stream are encrypted and second portions of the encrypted elementary bit stream are unencrypted.
