The present invention relates to an information distribution method based on the incremental fountain, and belongs to the technical field of wireless data transmission. The information distribution method has the following characteristics: a data splitter is used at the transmitting end for arranging the data of the same layer number in the layered and encoded data sequence, so as to form a branch; the sum of the branches is the sum of the layers; a weighting sequence is designed according to the principle of smaller layer number and higher degree of importance; a scheduling parameter calculator is used for calculating the scheduling parameters of each layer in each original data block; the scheduling parameters are transmitted to a scheduling device, which is used for controlling the work of the fountain encoder of different layers according to different probabilities, so as to complete different types of redundancy protection of different layers, thus the system has the capacity of adapting to complex and changeable states of the channel. The method can be used for effective data distribution of no feedback and low redundancy in the poor channel.
