Rating Meter for Digital Terrestrial Television with ISDB-T Standard Through Transport Stream Analysis

Abstract:

The television programming rating represents, as a percentage, the number of households or viewers who find the television turned on a given channel, program, day, and time. In this project, a rating meter was implemented for the international ISDB-T system based on the analysis of the Program Specific Information tables and Service Information tables of the Transport Stream that carries the information of the television channels and the content of the Electronic Programming Guide, whose data is recorded in a database implemented for this purpose, where the viewer does not need to interact or answer questions about the programming. The implemented prototype uses a full-seg ISDB-T receiver to capture the signal from the air and obtain the transport flow. For the information processing, an interface was designed in Java that evaluates the flow based on the service tables, event information, time offset, and the descriptors that describe information about each event. The data with the name of the channel, name of the program, type of service, start and end time are recorded in the database and automatically generate the rating report. The tests were carried out with the reception of open television channels in the city of Quito in Ecuador.
