    摘要: A method and apparatus for transmitting urgent data by embedding the urgent data in normal data is provided. An urgent data signal is embedded in a normal data signal in such a way that the normal data signal is not affected, and then the urgent data signal is transmitted together with the normal data signal thereby stably transmitting urgent data without using a separate urgent data line.
