Patent ID: 8243922

Claim:
An end user system comprising: a communication interface configured to receive content in a compressed protected state and transfer the content in the compressed protected state, wherein the communication interface receives the content in the compressed protected state from a content provider system, wherein the content provider system modifies the content in an unprotected digital state to a protected state, compresses the content in the protected state to a compressed protected state, and transfers the content in the compressed protected state to the communication interface; a processing system coupled to the communication interface and configured to receive the content in the compressed protected state, and transfer the content in a decompressed protected state, wherein the processing system comprises a compression module configured to decompress the content to the decompressed protected state; and a user interface coupled to the processing system and configured to receive the content in the decompressed protected state, and output the content to a user in an analog form, wherein the user interface comprises a digital to analog conversion (DAC) process configured to process the content in the decompressed protected state with a key hard coded internally to the user interface to modify the content to the unprotected digital state, and convert the content in the unprotected digital state to the analog form.
