The Images and Signal Laboratory from the National University of Tres de Febrero (UNTREF) in Argentina has developed a data co-impression system designed to offer 3D on DTT infrastructures.

According to "TTV Media News", two years ago, the Ministry of Federal Planning called seven Argentine universities to develop an innovative proposal in the digital TV field. As a result, UNTREF focused its work on finding a way to have broadcast TV in 3D.

The University started to work with the Research and Training Laboratory on Advanced Informatics from the National University of La Plata (LIFIA), which developed specific software to intermediate the content track between the camera and the DTT set-top box.

The technology, says Mario Mastriani, head of the UNTREF laboratory, offers the possibility to broadcast up to four times more information, so where there used to be room for only one channel, there is room for four channels.

"In this prototype, on the other side, between the set-top box (STB) and the TV set, there should be an image unzipping device, but we are working with the National University of the South to produce a chip to include it directly in the tuning box."

In order for this technology to work as expected and confirm that this is a suitable technology, more research needs to be done. Content should also be specially-produced using stereoscopic cameras to convey the feeling of depth.
This is very good news for 3D DTT but there is a long way still to come...
