Considering digital multimedia broadcasting (DMB) with reverse channel through cellular, PCS, and WLAM, we propose Multi-Frequency Scheduling (MFS) algorithm for the data carousel. At the start of each carousel, the server/station chooses timely items and sequences them to configure a data carousel, regarding the statistics of client requests. Partitioning whole items into two sets, hot and cold, according to the request ratio, items have different broadcast frequency and preference when making a carousel. Simulations show that our proposed MFS features that the server answers as many client's requests as possible, while reducing clients' expected waiting time.
