Dear Mr. Houot, this is a very interesting contribution to the discussion. The reality is however that European homes will not cope the size of the screen you propose. Any broadcaster has to consider business aspects such as maximum needed bandwidth for transmission (= money to pay). Consequently it important to consider the "major population display size" in consumers homes. Any serious broadcasters has also to consider that the major population are not "geeks". If you buy some reports of GfK, displayserach etc. then you will find that the major sales of display are in area of ~ 37 inch diagonal with an trend to ~ 42 inch. The display we used with 50 and 52 inch were already above the majority. We cannot expect that homes will become bigger, thus the space for large displays (or even a wall/screen for projector systems) is rather limited. We have also seen that the TV experience with good HDTV on the screens we used in the tests makes a difference to SDTV and in fact is appreciated by the assessors. Please send me the scientific data which you have used for your statements. This should be interesting. In conclusion, I have to say that your arguments do not hold against the results of the tests for TV broadcasting applications.
