This paper proposes a scheduling scheme for push broadcast services in digital broadcasting. In previ ous work, scheduling was considered a problem of one dimensional allocation focusing solely on the time di mension. We redeļ¬ne the problem as that of two dimensional allocation, with both time and bandwidth of the data taken into account, and propose a scheme called 2DS, designed for digital broadcasting. The paper dis cusses a method of determining the optimal broadcast in terval for each data item in two-dimensional scheduling. Beyond that, we propose a scheduling algorithm based on the estimated optimal broadcast intervals. Perfor mance evaluations verify effectiveness of the proposed scheme.
