- Frontend drivers that are usually implemented as two separate drivers:

  - A tuner driver that implements the logic with commands the part of the

    hardware with is reponsible to tune into a digital TV transponder or

    hardware with is responsible to tune into a digital TV transponder or

    physical channel. The output of a tuner is usually a baseband or

    Intermediate Frequency (IF) signal;

On almost all frontend hardware, the bit and byte counts are stored by

the hardware after a certain amount of time or after the total bit/block

counter reaches a certain value (usually programable), for example, on

counter reaches a certain value (usually programmable), for example, on

every 1000 ms or after receiving 1,000,000 bits.

So, if you read the registers too soon, you'll end by reading the same

Drivers register entities with a media device by calling

:c:func:`media_device_register_entity()`

and unregistred by calling

and unregistered by calling

:c:func:`media_device_unregister_entity()`.
