Patent ID: 7802013

Claim:
A data transmission method, suitable for transmitting a first data table from a server to a mobile device, wherein the first data table comprises a plurality of data fields, and each of the data fields has an upper bit number limit, the data transmission method comprising: calculating a maximum used bit number of each of the data fields in the server; identifying the maximum used bit number of each of the data fields, wherein when the maximum used bit number of one of the data fields is 0, the upper bit number limit of the data field is updated so as to reduce the upper bit number limit, when the maximum used bit number of one of the data fields is not 0, the upper bit number limit of the data field is updated to be equal to the maximum used bit number of the data field; generating a second data table according to the updated upper bit number limit of each of the data fields; and transmitting the second data table to the mobile device.
