	abstract = {<p>The main issues characterizing current video applications are their strong requirements for huge storage spaces andtheir need for timing synchronizationVideo data storageis a critical research topic due to the so
called IObottle
 neck problem which aects the quality of service of videoapplicationsThis paper introduces a two level video datarepresentation model in order to guide video data storage on a tertiary storage subsystemA simulation model hasbeen developed to evaluate dierent video placement strate
gies based on both Constructive and Iterative ImprovementapproachesExperimentation has been carried out for theproposed placement approaches as well as for a typical ran
dom placement policy which serves as a comparison refer
 enceIterative Improvement placement has been proven tooutperform the other considered video data placement ap
proaches in both seek and service times.</p>
