Customer stories: Acreo Develops Visual Ergonomic Standards for Future 3D TV

How do you know that a computer or TV display is good? TCO Development is a Swedish certification body whose TCO certified labels are attached on roughly 50 percent of the displays globally. The certification makes it easier for consumers and personnel in procurement processes to make informed decisions. Since the beginning of the 1990s, Acreo has assisted TCO Development as a technology expert when it comes to the visual ergonomic test methods and requirements of displays. During the last couple of years, Acreo has drafted a proposal for quality standards for 3D TV in cooperation with TCO Development.

While 3D cinema has been a tremendous success with new 3D cinema installations in a large number of towns in Sweden, 3D TV isn’t there yet. Partly because of lack of content, partly due to the fact that display manufacturers and broadcasters have not yet decided what standards to use.

Recently, Acreo has taken part in several projects involving standardization development for 3D TV. In collaboration with TCO Development, Acreo has drafted a proposal for measurement methods and requirements for quality 3D TV.

“We developed the specification for review. It is TCO Development who owns the specification and they will push it forward. Right now, it’s in the hands of TV manufacturers in South-East Asia,” says Kjell Brunnström at Acreo.

Acreo has also been involved in 3D TV standardization development in cooperation with the Video Quality Experts Group (VQEG) and the International Committee for Display Metrology (ICDM).

Experimental studies using test subjects

Acreo carries out experimental studies where participants test different types of equipment.

“We let them watch short videos, and then they get to assess the picture quality,” says Kjell Brunnström.

In one study, the aim was to decide the best algorithm for compression techniques in future 3D video data. The video quality test was performed by direction of Moving Pictures Experts Group (MPEG), and Acreo was one of 12 labs worldwide to be selected. In another study, Acreo examined the best way to handle losses of packet data when viewers watched videos on the web. One of the conclusions was that it, in many cases, was better to go back momentarily to the 2D format, when the 3D picture experienced losses of packet data.

The results can be used by broadcasters and telecom operators

The work of Acreo can be used by both broadcasters, such as SVT, TV4, and Video On Demand providers and telecom operators. In the recently started research project EFRAIM, internet companies, broadcasters and telecom operators in all parts of the value chain will cooperate with Acreo to examine the future ecosystem of media distribution.
