Scheduling Methods on Broadcast Systems Considering the Number of Available Channels

摘要

Due to the recent digitization of broadcast systems, broadcasting continuous media data such as music and movie have attracted great attention. On continuous media data broadcast, since clients wait for starting playing data, various methods to reduce the waiting time are studied. These methods usually divide the data into some segments and broadcast them via several channels. However, for reasons of specification of hardware or facilitation of process, the number of available channels can be restricted. In this paper, we propose scheduling methods to reduce the waiting time of clients considering the number of available channels. Our proposing methods extend the AHB scheme to adjusts the number of channels by controlling data size of each segment.
