The "Digitus DN-30210" is a Bluetooth adapter for use with computers and notebooks, not specifically designed for televisions. Here are some key points to consider:

- This device allows Bluetooth devices to be connected to a computer or notebook via a USB port, but it is not designed to be used directly with a TV.
- To connect your tablet or phone to your TV, you would need a device that is compatible with your TV's Bluetooth technology, which this adapter is not.

If you want to connect your devices to your TV, you should look for a device specifically designed for this use, such as a Bluetooth receiver compatible with your TV.
