Disclosed is an apparatus and method for descrambling transport stream (TS) data, the descrambling apparatus including: a TS packet input unit for determining from the value of a header of TS packet data whether the TS packet data are scrambled, and outputting determination results and the TS packet data; a descramble controller for applying a control signal to the TS packet input unit for the TS packet input unit to read the TS packet data, and outputting a scramble determination signal of a corresponding state based on the determination results; and a descrambler for determining from the state of the scramble determination signal whether the TS packet data from the TS packet input unit are scrambled, and determining whether to descramble the TS packet data.
