A transmission and updating method and the apparatus thereof for consecutive changing data. The method comprising the steps: the server extracts the data set from the consecutive changing data at the predetermined time interval consecutively (101); the server compares the whole set of the latest data set with the whole set of the prior one in the form of symbol to obtain the changing string; vary the changing string to the changing set (102); transmit the changing set to one or more clients (103) so that the clients can update the data set to the latest data set according to the current data set (104). The method of the present invention divides the data set into several symbols, as the symbol is flexible, an item can be divided into multiple symbols, and the data sets are compared with the symbol as a unit to diminish the compared unit, so the byte length of the obtained changing string is reduced, such that the transmission quantity is reduced greatly, the transmission speed is increased and the requirement for bandwidth is reduced.
