GENEVA — The DVB Project is pleased to announce that at the 71st Meeting of the Steering Board, Phase 2a of the DVB-3DTV specification was approved. The specification will be submitted immediately to the European Telecommunications Standards Institute (ETSI) for formal standardisation. An amended DVB-3DTV BlueBook is to be published to reflect the addition to the specification.

The Phase 2a system, also known as “Service Compatible Mode” is designed to meet the needs of those who need to provide normal HDTV receivers with a 2D version of the 3D programme from the same broadcast channel, and at the same time improve the quality of the 3DTV images. Phase 2a provides a 2D version plus an MPEG MVC top-up signal. Although they are tailored to their different environments, both 3D Blu-ray and Phase 2a use MVC, which will enable receivers to include both capabilities.

The 3DTV Phase 1 specification was published in 2011 for “Frame Compatible” delivery, where the essential requirement was that existing HDTV set-top boxes would allow viewers to watch 3D (if they had a 3D display). This is the most used 3DTV broadcast form in the world today.
