Title:ApplicationofASIInterfacePerformanceMetricsinDVB-TSystems
Abstract:
TheASI(AsynchronousSerialInterface)isawidelyusedinterfaceinthedigitalvideobroadcasting(DVB)domain.ItplaysacrucialroleinthetransmissionofdigitaldatabetweenvariouscomponentswithinaDVB-Tsystem.ThispaperexaminestheapplicationofASIinterfaceperformancemetricsinDVB-Tsystemsanddiscussestheirsignificanceinensuringefficientdatatransmission.
Introduction:
