Clarifying 4K and Ultra HD; same thing?

There’s been a significant amount of market chatter on 4K and Ultra HD (or UHD), and there is likely to be magnified focus on 4K and UHD moving into the upcoming IBC Expo. To-date, TV manufacturers, broadcasters, and many others are using the terms interchangeably. While the two standards are technically different, from a consumer perspective the difference is minimal.

4K
In simple terms, 4K is a professional production and cinema standard, while UHD is a consumer display and broadcast standard. The term “4K” originates from the Digital Cinema Initiatives (DCI), a consortium of motion picture studios that standardized a specification for the production and digital projection of 4K content.

UHD
Ultra High Definition, or UHD for short, is the next step up from what’s called full HD, referring to resolution. UHD is not the same as the 4K resolution, yet most TV or monitors you see advertised as 4K are in fact UHD.

So what’s the story?
Naturally TV manufacturers are aware of the differences. Some are using “4K UHD,” which may be to avoid conflicting with DCI’s actual 4K standard, but many appear to be using “4K” as the standard description, which may be purely for marketing purposes.
