The invention provides a data processing method, apparatus and system. The data processing method comprises the steps: acquiring the first target data of the next update cycle of the current presentation data; sending a new data request message within the update cycle of the current presentation data, and acquiring the second target data of the next update cycle of the first target data; judging whether the second target data is greater than the first target data; and if the judged result is NOT, adjusting the rate of change of the presentation data, and enabling the presentation data to be increased to the first target data within the residual time before the current presentation data reaches the second target data according to the adjusted rate of change. By means of the data processing method, apparatus and system, the data processing error correction and fault tolerance capability can be improved, and the data processing reliability and the data presentation effect can also be improved.
