To protect copyright, the present invention provides a tamper-proof content-playback system. Its content-playback unit has the following I/O characteristics: A) at least a portion of its content input(s) is encrypted digital signals; B) at least a portion of its content output(s) is non-digital (e.g. analog) or non-electrical (e.g. image) signals. Only secure data connections are allowed for decrypted contents inside the content-playback unit. Accordingly, its components are preferably integrated into: a single chip, a single package, or a chip/package-on-panel.
