Logo-krig: Her er amerikanernes UHD logo


 


Forleden udkom et europæisk logo for Ultra HD TV, og nu er amerikanerne klar med deres eget.


Forleden var det brancheforeningen Digital Europe, der har støtte fra IT-, mobil- og elektronik-producenter verden over, der kom med deres nye logo for 4K UHD.


Nu er det så amerikanernes tur, til at lancere deres eget UHD logo. Dermed er er lagt op til en “logo-krig” imellem organisationerne, og dermed en øget risiko for forvirring hos forbrugerne.

Det er den amerikanske brancheorganisation for forbrugerelektronik, CEA, der nu udsender de nye UHD logoer. For faktisk er der to hos dem, et der dækker display-enheden (TV, projektor eller monitor) og så et “connected”, der dækker streaming indhold i Ultra HD.


Det er de to logoer der ses her ovenfor. Kravene for at bruge de logoer kan ses i info-boksen herunder.
