ABSTRACT:
An approach is provided for storing and retrieving digital audio/video data. A system bus of fixed width transfers data bits. The data bits form a bit pattern. An interface is coupled to system bus and is configured to alter the bit pattern of the data bits, according to a prescribed scheme. A hard disk drive is coupled to the interface and is configured to store the altered data bits. The approach has particular applicability to a digital set-top box for a direct satellite television system.
