Automatic DVB Performance Measurement Tool

Abstract: Nowadays, there are several different standards that specify what performance should expectfrom a DVB (Digital Video Broadcasting) receiver, such as NorDig Unified, DTG D-Bookand EICTA MBRAI. These standards are complicated and thousands of measurements areinvolved, so it would be very handy to repeat the measurements with an automatic tool. In thisthesis work, only NorDig Unified 2.1 is concerned.

Since the test cases in NorDig Unified requirements for integrated receiver decoders are quitesimilar and repeatable, the work efficiency to fully evaluate the DVB performance could beimproved by an automatic application. It would increase the test quality and decrease themanual labor a lot for each product.

Implementation of the tool is the most important part in this project. The application runs on acomputer with a user friendly graphical interface. Its main task is to control the calibratedsignal generator (Rohde & Schwarz SFU) and test the set-top boxes (STB) in Motorolaproduct range. Besides, a database has been designed to store all these testing results, andanalysis on the data has been presented as well.

In this project, the automatic DVB performance measurement tool is developed in MicrosoftVisual C++ 6.0 with an ODBC (Open Database Connectivity) driver connecting to thedatabase, and data presentation is done in Microsoft Excel 2003 using VBA (Visual Basic forApplication).
