A transmission method for synchronously transmitting asynchronous data is disclosed by the present invention, and the method includes: a transmitting end encapsulating the asynchronous data into a synchronous data frame, and synchronously transmitting it to a receiving end; and the receiving end receiving and de-encapsulating the synchronous data, writing the obtained asynchronous data into a buffer of the receiving end, reading the asynchronous data by using a reading clock of the asynchronous data and outputting the asynchronous data to a receiving apparatus for asynchronous data; wherein, the receiving end also adjusts the frequency of reading clock by using data depth information of the buffer, increases the frequency of reading clock when the data depth in the buffer increases, and outputs data representing idle when the buffer is empty. A transmission system and receiving apparatus for synchronously transmitting asynchronous data are also disclosed by the present invention. The invention solves the problem of the slip code during continuous synchronization transmission of the asynchronous data, and effectively prevents the data overflow of the buffer. |
