Title:
A TRANSMISSION AND UPDATING METHOD FOR CONSECUTIVE CHANGING DATA SET AND THE APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/016857
Kind Code:
A1
Abstract:
A transmission and updating method and the apparatus thereof for consecutive changing
data. The method comprises 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.
