How Do Carrier Pigeons Know Where to Go?

The video tutorial explores how car radios display song and album information using Radio Data Systems (RDS). It delves into the basics of radio technology, explaining how radio waves are used for communication beyond entertainment. The tutorial covers how radio stations broadcast using FM and AM, and introduces RDS as a protocol for sending additional information. RDS, initially a European standard, is now used globally and has applications in various appliances, aiding in energy conservation and emergency alerts.
