A scheduling method for continuous media data broadcasting considering commercial contents

Purpose: The purpose of this paper is to propose a scheduling method called the "Asynchronous Harmonic Broadcasting Considering Commercial (AHB-CC)" method, to reduce waiting time for continuous media data broadcasting. Design/methodology/approach: The authors analyze and evaluate the performance of the proposed AHB-CC method. Findings: The authors confirm that the proposed method gives shorter average waiting times than the conventional methods. Research limitations/implications: A future direction of this study will involve making a scheduling method where the server concurrently broadcasts data and commercial contents. Also, maximum buffer size needs to be considered. Practical implications: In general broadcasting systems, the server broadcasts the same data repetitively and clients wait until the first portion of the data is broadcast. Although the server can deliver the data to many clients concurrently, clients have to wait until their desired data are broadcast. Originality/value: The AHB-CC method presented in the paper further reduces waiting time by scheduling an effective broadcast that considers the playing time of commercial contents.
