摘要：

The aim of the Desktop-projector project is to create a software tool (application) for more effective teaching in computer classrooms, especially in case where a classic projector cannot be used. The Desktop-projector is typically used for showing presentations or other activities carried out on the teacher's desktop on other desktops. The teacher's desktop is broadcasted to other computers on a local area network. The article describes software architecture of the Desktop-projector solution and discusses problems with visual data transfer over computer network, such as UDP datagram loss and sufficient performance (speed) of the transfer. After considering the results from this article we have obtained the optimal configuration values required for proper setting of the application's parameters, ensuring good enough quality of the Desktop-projector solution.
