A Second DVB-3DTV Delivery System Has Been Approved

October 22nd, 2011 · 2 Comments · General 3D News


The DVB Steering Board has announced the approval of the Commercial Requirements for a second DVB 3DTV delivery system. Termed “Service Compatible”, the second system is a solution required by content deliverers that enables the 2D and 3D versions of a programme to be broadcast within the same video signal, so that new 3D televisions and next-generation STBs can receive high 3D programmes, while consumers with existing 2D HDTV receivers and set-top boxes can watch a high-quality 2D version. This 2D picture will probably be either the left or right frame of the 3D “stereo pair”.

Earlier this year, in February, the DVB Steering Board has approved the specification for a first phase DVB 3DTV delivery system (Digital Video Broadcasting (DVB); Frame Compatible Plano-Stereoscopic 3DTV (DVB-3DTV) BlueBook). This system was developed for broadcasters and content deliverers needing a system that works with the already existing HDTV receivers, provided they are used together with a compatible 3D display. This approach, termed “Frame Compatible”, is now a principal system in use for DVB 3DTV delivery throughout the world when talking about 3D TV channels. However the level of quality provided by this “compatibility” solution for 3D TV channels could be further improved using a new standard and new hardware providing better image quality and higher resolution.

For convenience, this second approach is termed DVB-3DTV “Phase 2a”. The Commercial Requirements should shortly be available as a “BlueBook” on the DVB website for everyone interested in more details. The DVB Technical Module has been asked to complete the preparation of the specification for Phase 2a before the end of summer 2012. Phase 2a will provide additional opportunities for 3DTV services, complementing the first specification, which is referred to now for convenience as 3DTV Phase 1. The DVB is also taking into account the requirements of content deliverers wanting to continue the use of a Phase 1 signal, but wish to provide additional information to improve the image quality for those with “new” receivers. This may result is a Phase 2b specification in due time.

Safe 2D Graphics Insertion in Stereoscopic 3D Video Material

September 25th, 2010 · No Comments · Other S3D Tech


Jonathan Jenkyn (3D product specialist) and Simon Hailes (Chief Technology Officer) from Screen Subtitling Systems have released a whitepaper entitled “Safe insertion of graphics for stereoscopic material” which goes some way to define the issues that broadcasters will encounter when trying to use traditional 2D approaches with the new 3D TV channels. You know it is much easier to overlay 2D graphics, such as the logo of a TV channel, subtitles over a movie or some rolling text with the latest breaking news as well as some other graphical and text objects over the traditional television broadcasts in 2D. However when you have a 3D broadcast, no matter if it is live or a pre-recorded movie things can get a bit messy if you do not consider the depth of the 3D video being shown when placing some 2D graphical elements on top. The approach that Jonathan Jenkyn and Simon Hailes suggest is to use the so called disparity maps for correctly placing 2D graphical elements on top of 3D video material, so if you are interested into that you can check out the whitepaper for more information.

I’m a bit late with this one, but there is still time for you to plan a visit to the International 3D Stereo Film and Technology Festival – 3D Stereo Media, that is going to be held from 30th November till 3rd December 2009 in Liège, Belgium. The festival is for both professionals in the Stereo 3D field, but also for the general public, so that everyone interested in the various forms of 3D stereo, in particular 3D cinema, 3D television, and 3D games is welcome to join in. During the festival there will be screening of various 3D movies and exhibitions for different Stereo 3D technologies and solutions and meet a lot of professionals in the field. So if you are in Europe you might as well plan the festival in your busy schedule… ;)

The 3D Stereo MEDIA 2009 is divided into two strands:
– A 3D Stereo Film Festival, which will take place in the Kinepolis cinema complexes in Liège,
Brussels and Antwerp between 30 November and 3 December 2009
– A 3D Stereo Technology Festival, which will take place at the Palais des Congrès in Liège
from 1 to December 2009.

Visit the official website of 3D Stereo Media 2009 for more info…
