Control system for video advertising based on Raspberry Pi

This paper describes the implementation of controlling system for the multimedia content on multiple Raspberry PI platforms. The purpose of the system is to implement a cheap solution for upgrading an existing video advertising solution to a smart solution that can display content according to local conditions. The software system, designed in Java, has two components: a Server with the purpose of controlling content that will be sent to the clients, and multiple Clients that control the local multimedia content, each client running on Raspberry PI. Commands and responses sent by the two subsystems through the network are encrypted using the AES cipher. The problems of using the Raspberry Pi platform for the implementation of such systems are analyzed.
