But what we can easily forget is that the consumer is not able to consume media in a similar way across different devices. What the consumer does is shaped, in part, by his or her media context. n recent years, consumers and media latest technologies like HDTV or maybe in personal services. People will search for Iorganisations have been overwhelmed the future UHDTV and 3DTV. The screen more in depth information around an item by new media consumer devices, and by size is enormous, the expected quality on the big screen, vote, give feedback, or new types of applications and services (video + sound) high, the attention span is inform their friends. This is the situation related to media. The original way to cope long, and the interactivity is rather limited. where real and personal interactivity will with this was to develop a multiplatform People want to be surprised, informed and take place. Here are opportunities for strategy. In essence, taking the same entertained.

In his ongoing series of articles on 3DTV, David Wood explores some of the factors that can affect the quality of perception. he route to ‘First Generation’ 3D 3DTV should be made based on subjective which influence the quality of realism of the Ttelevision (S3D) requires journeys down evaluations using 50” screens at five times image (assuming the programme maker’s many roads. These include the development picture height. There are reasons why this intention is to achieve maximum realism). of broadcasting formats for different is a good combination, because it removes These are as follows: circumstances where different degrees of some possible elements of bias in the testing. • The basic quality of the Left and Right eye existing and new equipment are needed There may be other (and better) ways of images themselves. All of the elements that by the viewer. These are being considered breaking the psycho-physical issues down affect 2D images come into play. It matters in the DVB Project as ‘Phase 1 3DTV’ and to manageable portions, but one way is to whether the image (using the ITU acronyms) ‘Phase 2 3DTV’. consider the problem in three chunks, but is ‘LDTV, SDTV, EDTV, HDTV, or UHDTV’. As well as this, there is much work to be which are all inter-related to an extent: The 3D quality will get better as we step up done on production technology for 3DTV, • The realism (‘quality’) of the image the ‘2D quality’. It is because we have HDTV including developing rules for production • The eye discomfort associated with using today that 3DTV becomes more attractive grammar that will provide programmes that the system, and than it was in the SDTV and EDTV days. are most comfortable to watch.
