Overview of SDT and EIT analysis in DVB systems

Abstract

This article presents the service information in the digital broadcasting systems (DVB). It gives some details about the transport stream and about some special information, which is contained by different tables. The transport stream is a communication protocol for audio, video and data transmission, which is specified in the MPEG-2 systems. A service description table (SDT) contains data describing the services in the system. An event information table (EIT) comprises data, which specifies the events or the programs, such as event name, start time and duration. Finally, a transport stream analyzer program will be introduced, which is responsible for gathering information from SDT and EIT tables. The application processes the descriptors belonging to the corresponding tables and displays the data from these tables.
