摘要
Disclosed is an apparatus and method for processing transport streams (TSs) and a delay-controlling apparatus that assigns a predetermined delay to MPEG-2 TS packets fed into a POD module in a digital cable broadcasting system, irrespective of a time delay caused by descrambling scrambled input TS packets, the apparatus including: a demultiplexer for receiving TSs and dividing them into scrambled and non-scrambled data; a descrambler controller for receiving the scrambled data from the demultiplexer and descrambling it; a delay controller for receiving the non-scrambled data from the demultiplexer and the descrambled data from the descrambler controller and delaying them by a predetermined time; and a remultiplexer for receiving the data from the delay controller, multiplexing them, and outputting the multiplexed data in the TS format.
