A novel integrated measurement and analysis system for digital broadcasting

To analyze numerous field test data of digital broadcasting systems efficiently, field measurement systems have been integrated and become more intelligent. In this paper, we present the Integrated Measurement and Analysis System (IMAS) which manages DTV and TDMB (Terrestrial Digital Multimedia Broadcasting) test data very efficiently. This system can measure various parameters of DTV, T-DMB as well as analog TV (ATV) and FM broadcasting in fixed or mobile measurement mode. All the test equipments are connected through the local area network and managed by the system controller with an open device interface. Every test result can be converted into specific standard formats and stored in the main data base which can be accessed with a web graphical user interface through the intranet.
