2ª fase de la DVB-3DTV en marcha

julio 12, 2012 3 comentarios

Sólo hace falta que publique un artículo quejándome del formato SbS para que a los pocos días se apruebe la 2ª fase de la DVB-3DTV.

Básicamente, dejamos atrás la época del “frame compatible” y entramos en la época del “service compatible”, o lo que es lo mismo, las transmisiones 3D se harán en un formato (MPEG MVC) de tal forma que si tienes el SetTopBox adecuado y la pantalla 3D adecuada, verás el contenido en 3D (y con mejor calidad que hasta ahora), pero si tu pantalla es FullHD (no es 3D), y/o no tienes el STB adecuado, lo verás perfectamente en 2D sin ver la imagen doble.
Lo que es seguro que más de uno tendrá que cambiar su STB para su pantalla 3D, porque pocos soportaban MVC (sólo los de gama más alta).
Esta norma afecta exclusivamente a las transmisiones de TV3D. Las transmisiones 2D en FullHD llegarán sin cambios tanto a pantallas 2D como a pantallas 3D.

La nota de prensa está lanzada desde ayer día 11 de Julio. Ver nota de prensa oficial

La DVB aprueba la especificación de TV3D

Os paso la nota en inglés, que se hizo pública ayer por la tarde.
En resumidas cuentas, aceptan TaB (Top and Bottom) y SbS (Side by Side) en ciertos formatos:

  • 720p (50, 59.94, 60 TaB & SbS)
  • 1080i (25, 29.97, 30 sólo SbS)
  • 1080p (23.98, 24 TaB y SbS)

y también regulan la disparidad en base a una pantalla de referencia de 11.520 pixels. Para más detalles, leed el documento Bluebook A154 haciendo click en el enlace más abajo.

Geneva – 21 February 2011. DVB is pleased to announce that on February 17 at the 67th Meeting of the Steering Board, the DVB-3DTV specification was approved. The specification will be submitted immediately to the European Telecommunications Standards Institute (ETSI) for formal standardisation. BlueBook A154 ‘Frame Compatible Plano-Stereoscopic 3DTV’, (DVB-3DTV) has been published and is available for downloading from the DVB website.
The Commercial Requirements for the DVB-3DTV specification were agreed in July 2010 after consultation with key industry groups. The Commercial Module’s Sub-Group on 3DTV was chaired by David Wood (EBU) and the Technical Module (TM-3DTV) was chaired by David Daniels (BSkyB).
The specification specifies the delivery system for frame compatible plano-stereoscopic 3DTV services, enabling service providers to utilise their existing HDTV infrastructures to deliver 3DTV services that are compatible with 3DTV capable displays already in the market. This system covers both use cases of a set-top box delivering 3DTV services to a 3DTV capable display device via an HDMI connection, and a 3DTV capable display device receiving 3DTV services directly via a built-in tuner and decoder.
Plano-stereoscopic imaging systems deliver two images (left and right) that are arranged to be seen simultaneously, or near simultaneously, by the left and right eyes. Viewers perceive increased depth in the picture, which becomes more like the natural binocular viewing experience. Since 2010 many 3DTV capable consumer products have been launched in the market.
The DVB-3DTV specification is also accompanied by the Subtitling Systems specification (EN 300 743), which provides a mechanism that allows subtitles and other onscreen graphics to be best positioned so that they can be viewed correctly in the stereoscopic picture. There are also amendments to the Service Information specification (EN 300 468) and to the specification of audio and video coding over the MPEG-2 Transport Stream (TS 101 154).
“I would like to extend my thanks to all the Members that participated in both the Commercial and Technical Modules to bring to fruition the DVB-3DTV specification in such a short period of time. DVB standards provide one of the keys to commercial success and stability for the industry and the consumer,” commented Peter Siebert, Executive Director, DVB.

About DVB
Digital Video Broadcasting (DVB) is an industry-led consortium of over 250 broadcasters, manufacturers, network operators, software developers, regulatory bodies and others committed to designing global standards for the delivery of digital television and data services. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to create unity in the move towards global standardisation, interoperability and future proofing.

DVB dominates the digital broadcasting environment with thousands of broadcast services around the world using DVB’s open standards. There are hundreds of manufacturers offering DVB compliant equipment. To date there are over half a billion DVB receivers shipped worldwide. DVB standards are also widely used for other non-broadcasting applications such as data on the move and high-bandwidth Internet over the air. Further information about DVB can be found at:,, and
