Remark about reception of HD channels: the reception of HD
DVB-T channels requires a better signal than normal SD quality
channels. For that reason the TV should be positioned at places
where the reception quality is higher. If the reception is not
strong enough, the image of HD channels can be interrupted or
from bad quality.
