15. It is essential to have DTT reception equipment which supports high definition (HD)?

It is not currently essential, but highly advisable.

The technological developments indicate that, in the future, transmission will be high definition only.

If you have or you plan to acquire reception equipment that only supports SD transmissions, you could be left unable to access DTT services if transmissions become exclusively HD.
