DigiraI Video Broadcasting for Handhelds (DVB-H) is the latest DVB standardfrom the DVB Group targeting handheld, battery powered devices such as mobjle telephones, PDAs(Persona1 Digital Assistants). etc. DVB-H enables IP data services including low definition TV services to be received on battery powered handheld terminals. Time Division Multiplexing (TOM, is the technology that is usually used in computer and telecommunication systems for resoursce allocation. Time slicing is based on TDM and is one of the characteristics of DVB-H. This paper presents a basic model for predicting the power saving achieved by the time slicing algorithm used in DVB-Hfollowed by analysis of theperformance ofthe algorithm based on simulations using Matlab and Opnet; The simulations required the writing of Matlab and Opnet code to model the esfect oftime slicing. The model and simulations presented illustrate the significant power savings that can be achieved by time slicing.
