DVB makes public its commercial specifications for 3D

The DVB brings together in a document around twenty recommendations for the development of 3D in a side-by-side format. One of the key points is the need to have left and right images located in a 'spatial multiplex' that will allow a decoder to process the resulting signal in the same way as it does with a conventional high definition signal.

The DVB has approved the commercial specifications for the development of 3D in a side-by-side format. The DVB working group has started from a 3DTV service provision scheme using the same infrastructure used by payment operators for the introduction of high definition services.

Far from being closed specifications, DVB has chosen to leave the door open to the development of new systems and although its intention from the first moment was the compatibility of 2D-3D receivers and televisions, it has finally become clear that it will not be possible.

In general terms, those first experiences being carried out by Canal+ in Spain or France or Sky in the United Kingdom would adapt to the twenty recommendations put on the table by the DVB.

One of the key points established in the document is the need to have left and right images located in a 'spatial multiplex' that will allow a decoder to process the resulting signal in the same way as it does with a conventional high definition signal. That is, according to ITU terminology, a 'Frame Compatible' format.

The DVB document, although it addresses 3DTV services up to the point of reception and decoding by a digital receiver, does not go into determining how the content has been received and decoded on the screen.
