The Hybrid DVB-T Stick is a USB device designed to receive Digital Video Broadcasting - Terrestrial (DVB-T) signals, which is a digital television broadcast standard. These sticks are commonly used with a computer to watch and record over-the-air digital TV broadcasts. "Hybrid" generally means that the stick is capable of receiving multiple types of signals, such as DVB-T (terrestrial), DVB-T2 (improved version), or even other formats like DVB-C (cable) or DVB-S (satellite), depending on the model.
To use the Hybrid DVB-T Stick on a Windows computer, you need the appropriate Windows driver and potentially some software for watching TV or recording broadcasts.
