ABSTRACT:
Disclosed is a deinterleaving system for receiving digital transmission data which is interleaved in units of a block and deinterleaving the received data. A sync signal is detected from the interleaved sync data which is included in the data of the received data block, and the deinterleaving is performed according to the detected sync data. In such a deinterleaving system, the transmission apparatus does not need to add a predetermined sync data to the interleaved source data when the data is transmitted, and the received data can be restored into the original data which was maintained prior to being interleaved.
