Video transport over Internet Protocol : timing synchronization

What about all the clocks in the world giving the same time ? Nobody would be late ? Maybe not. But the only thing that is sure is the following : it would considerably simplify the life of professional Video broadcasters. In fact, they are currently moving from SDI synchronous infrastructure towards asynchronous IP based networks. The benefits of IP transport are appealing. But a synchronization system should be provided. This master thesis aims at providing a synchronization system for intoPIX, a professional in the video industry. The synchronization system takes the form of an Embedded system running on a FPGA. A Precision Time Protocol instance is running on a Real-Time Operating System and is interfaced to some hardware components providing clock tuning capabilities. A more in-depth study of the controller stability under hard constraints is given. The system achieves synchronization performances lower than 100 microseconds.
