The TechniSat Mantis BDA HID Device is a TV tuner or digital receiver device, part of TechniSat's Mantis line of products, that allows a computer to receive digital TV signals (e.g., DVB-T, DVB-T2, DVB-C, etc.). BDA stands for Broadcast Driver Architecture, which is a Microsoft specification for TV tuner drivers. The HID in this context likely refers to Human Interface Device, a type of device used for communication with a computer, which could be a part of the TV tuner system or its remote control, such as a USB receiver or remote.

To use the TechniSat Mantis BDA HID Device on a Windows computer, you need the correct driver that enables communication between Windows and the tuner hardware. This driver will allow you to use the device with TV viewing software or other media applications like Windows Media Center or third-party apps like Kodi or VLC.
