Due to the continued popularization of broadcast and communications integration environments, streaming delivery using broadcast and communication is attracting great attention. In streaming delivery on an environment, clients concurrently receive such data as music or movies from both broadcasting and communication systems. Although conventional methods reduce the interruption time, they fail to consider the upper limit in the available bandwidth. In this paper, we propose a delivery method that reduces the interruption time by considering the number of clients. Our proposed method reduces the interruption time by setting the bandwidths of the broadcast and communication systems and making a delivery schedule.
