Abstract
An apparatus and method are provided for controlling a time deinterleaver for digital audio broadcasting (DAB) that reduces a required minimum memory capacity of a DAB receiver. The method and apparatus generate addresses for writing and reading interleaved data transmitted from a transmitter into/from a deinterleaver memory having a plurality of memory areas associated with a plurality of frames of the interleaved data. The apparatus comprises an encoder for outputting, upon receipt of frame information for a first set of frames, frame information for a second set of frames to write the first set of frames in unused memory areas, allocated for the second set of frames, out of the memory areas of the deinterleaver memory; and a ROM in which bit position information of the memory areas for the frames are written such that the memory areas for the first set of frames should not be overlapped with the memory areas for the second set of frames.
