A method for synchronization of audio and video signals

In order to successfully receive the Hybrid Broadcast Broadband Television (HbbTV) certificate, each device has to pass a series of tests. One of these tests is audio-to-video (AV) synchronization test. In this paper, a method which analyzes video sequences and detects whether their audio and video components are synchronized is proposed and implemented. The application is written in C++ programming language and uses several open-source libraries for reading video and extracting audio.
