A Consideration on Cached Video Content Management Methods Based on a Hierarchical Transition Rule

Abstract

In this study, we studied cached video content management methods in video content services for multiple quality in order to adapt to environmental changes of content usage, e.g., an access variation. The conventional method used the number of content access in the reference period. The access prediction method using multiple reference periods was proposed. In addition, a transition rule for hierarchical video was defined. Next, as content usage models, delivered content model, access variable model and quality variable model are defined. By simulation experiments, we considered the efficiency of the proposed methods for the conventional method.
