Abstract
A DVD recorder including a multiplexer that stores multiplexed audio data and video data in a memory device, and a data scrambler that reads the multiplexed data from the memory device and scrambles the multiplexed data to generate scrambled data, in which the scrambled data has a bit sequence that is different from the multiplexed data. The data scrambler stores the scrambled data in the memory device. The multiplexer and the data scrambler access the memory device using a common memory controller.
