Modular Design Construction: The advantages of a pure
digital system are many, but one drawback is the constantly changing delivery
formats for digital content. Each of these formats typically requires
specialized hardware and software, often with licensed IP and content copy
protection. For this reason, NAD places all digital interface circuitry on
easily upgradeable modules. NAD calls this 'Modular Design Construction' or 'MDC'.
