At present, a demand to the technology of contents distribution by which each user can request the desired content through network is increasing. There are some merits and demerits respectively with the existing on-demand systems for contents distribution, such as the methods based on broadcast and select transfer or multicast one. In this paper, we propose a hybrid scheduling method which adaptively uses both broadcasting and multicasting in order to improve the system efficiency. Adequate channel boundary to adopt two different transfer mechanisms is found through analytical consideration. Also, performance improvement of our proposal is verified in terms of response time and request blocking rate through computer simulation.
