These inaccuracies in EPG may harm features often offered by TV stream providers, such as planned recordings. Here we present a system for mitigating this problem called VideoAI. First, the broadcast is analyzed, and commercials are detected by the first module using YOLO neural network. Next, the EPG is synchronized with real broadcast by minimizing the partition dissimilarity score. We evaluate VideoAI on different scenarios and show that it can adjust EPG to the real broadcast.enDla wszystkich w zakresie dozwolonego użytkuFair use conditionelectronic program guides synchronizationdetecting TV commercialsbroadcast monitoringsynchronizacja elektronicznych przewodników programowychwykrywanie reklam telewizyjnychmonitorowanie transmisjiRozdział - monografiaLicencja PŁLUT License10.34658/9788366741928.37
