Abstract
In an error data removing apparatus and method by decoding delay in a DTV system which employs a decoder of the VSB standard, respective segments or respective fields are divided into area 1 and area 2 using a starting point of decoded data as a reference to provide the decoded data of said area 1 section without involving delay and provide the decoded data of said area 2 section by delaying as long as a sync signal. A memory is utilized as the decoded data delay apparatus, and at this time, a value of a counter used for generating an address for reading/writing of the memory is utilized to delay the segment sync signal and field sync signal as required without separately using flip-flop or memory.
