TV Tuners must be configured correctly and conform to one of the 2 standard API’s below:

Windows BDA: Broadcast Driver Architecture (BDA) is a Microsoft standard for digital video capture on Microsoft Windows operating systems. It encompasses the ATSC and DVB standards and gives developers a standardized method of accessing TV tuner devices (usually PCI, PCI-E or USB). It is the driver component of Microsoft TV Technologies, and is used by hardware vendors to create digital TV tuning devices for Windows, and also to support new network types or custom hardware functionality.

Linux DVB API: The term Digital Video Broadcasting (DVB) is originally a synonym for Digital TV (often written short as DTV), and refers to telecommunication systems that send TV signals by way of digital transmission schemes, in contrast to the older, traditional, methods of signal transmission employed by Analog TV systems. Consequently, the Linux DVB API is essentially a kernel interface for Digital Video Broadcasting (DVB) device drivers.
