Patent ID: 7848520

Claim:
An electronic storage device for facilitating transmission of multiple partial encrypted digital video content, comprising: a segment of digital video content recorded on the electronic storage device, the digital video content data read into the electronic storage device to create a data structure comprising: a first set of data packets encrypted under a first encryption process so that the first set of data packets can be decrypted by a first decryption process; a second set of data packets encrypted under a second encryption process so that the second set of data packets can be decrypted under a second decryption process; wherein the first set of video data packets and the second set of video data packets, when in unencrypted form, represent duplicate copies of the same video information; a third set of data packets containing unencrypted video data, said third set of data packets containing video data content that is contextually contiguous to said first set of data packets and said second set of data packets, and wherein the first set of data packets together with the third set of data packets represents all video content in the segment of digital video content; wherein the second set of data packets together with the third set of data packets represents all video content in the segment of digital video content; the segment of digital video content having a data structure enabling the first set, the second set, and the third set of digital video content to be read out of the electronic storage device in an order that facilitates decryption of the segment of digital video content by use of a decrypter having capabilities for decryption of encrypted information under the first decryption or by use of a decrypter having capabilities for decryption of encrypted information under the second decryption process; and wherein the storage device stores the data structure including the first, second and third set of data packets at a transmission facility for transmission to a receiver device.
