In order to perform the production testing of the video quality of manufactured set-top-boxes for digital television, an FPGA-based measurement system is designed. Background on sampling and video signals are given, as well as the requirements given by Motorola. From this, a design is proposed and implemented. The demonstrator works as planned and shows good performance in regards to signal to noise ratio and differential gain. The implemented digital communication protocols, such as USB and I2C, also work as expected. The main conclusion from this thesis is that implementing video test systems using FPGA is a good approach offering many advantages compared to commercial video measurement instruments or plug-in cards for PCs.
