If the target TS stream is the TS stream at the buried point C, that is, if the target TS stream is not the TS stream at the buried point D, the range of X bytes extracted from the TS stream at the buried point C is enlarged, and when the range of X bytes is not greater than the preset range, the step of extracting X bytes in the preset range of the target TS stream is executed, wherein X is a positive integer.
