Abstract
With the widespread of terminals, such as mobile phones, equipped with both Digital TV reception capability and Internet connectivity, interactive TV services are becoming more popular and useful. This paper analyses the control accuracy of the access control method proposed for interactive TV services. The proposed method performs access control by utilizing random sampling and estimation. Therefore, error during control is somewhat inevitable and the accuracy of control becomes a problem. This paper analyses the cause of the various types of error expected while adopting the proposed method. The control accuracy and the volume of error of the proposed method are evaluated through numerical calculation. The obtained results quantitatively demonstrate the maximum values and the range of the control error when the proposed method is applied. Based on the obtained insights and results, adequate settings of control parameters and capacity planning of the system providing interactive TV services are illustrated.
