The number of information contained and disseminated at the same time by a hologram of high optical quality, one square meter of opening, being able to be observed of near fully being able to appreciate in a great angle its true relief with space-time high definition, would be about the million billion (Peta) “0” and “1”…

In telecommunication, the great volume of information of this “instantaneous totality” of the photonic writing can be only conveyed at the extreme speed of the light by optical way, as through a “telescope”.
However for the reception with a processing capacity of one gigabit a second electronic writing, one would need a million second to treat this hologram, that is to say twelve days.
And for ninety thousand specimens necessary to hypothetical a only one hour animation at a rate of twenty-five a second following our immutable retinal persistence, it would be necessary then nearly three thousand years of hologram treatment per hologram.
Even at a speed thousand times higher than the level of a terabit a second, it would still be necessary nearly three years to treat hologram by hologram this hypothetical animation only one hour starting from a micro-computer.
Moreover on the level of the screen whose high definition is already difficult to reach for an electronic image with two dimensions, it is inconceivable in optoelectronics to be able to direct with precision quasi-instantly and simultaneously each one of these million billion information extremely condensed for the restitution the holographic image which concerns only the field of the photonic one.
This is why, the transmission and the restitution of the extreme number of information specific to the space-time high definition of holographic images meet in data processing and optoelectronics of important restrictions of time and space.
Because of this “space-time obstacle”, the remote loading by Internet of a holographic optical part, like piece of music, is thus returned to the “Greek calends”…
It should be hoped that in this field of optical telecommunications, of the future prospects do not make gleam a forthcoming possibility of transmission and restitution of holograms via a future Internet network.
In this virtual world of data processing parallel with the real world, the treatment of a growing number of information ultimately slows down the access to the data required and stored in the memories where only on this level holography seems to have a brilliant future thanks to its high density of storage.

These “astronomical” figures which raise more of the field of “teleportation” destroy the possibility at horizon 2010 of replacing the screen of the computer by a “screen with hologram” dreamed so much by the data processing specialists wishing to make more convivial the “multi-media one” in real time, or of transmitting holograms by television as it was announced in the article “That the light is” magazine “Imaginez” November 1997 published by the S.E.M.L of Futuroscope, the Park European of the Image!… Or in May 2003, like it was revealed by a monthly magazine popularizing science, the amazing future of a certain research laboratory swearing to be able to transform, thanks to holography, an ordinary flat-faced screen in “monitor 3D”!…
It is true that vis-a-vis a holographic recording inside a fine transparent matter of this billion information at an extreme speed of some billionths of second, one would tend to lose of them the concepts of space and time…
More the skeptics and the laymen who prefer that it is to them known as what they want to hear well, will be able to perhaps approach from our point of view while starting by wondering about our own physiological impossibility to emit luminous radiations, compared to our faculty to emit sounds…

Instead of leaving to research mythical “the screen computer to hologram”, it is thus preferable to be satisfied to allow each individual, by the increase in the capacity of the data-processing memories, to design its chain of personal television, and to continue to make interactive in “virtual reality” for only one observer moving provided with a special helmet, the old stereoscopic images moving of the “cinema 3D” of the amusement parks.
Besides these last deserved since their origin the name of image in four dimensions but to simulated relief and for motionless spectators…
Television in four dimensions for a long time makes also already party our history with the animation of stereoscopic images simulated by the stereoscopic systems with ocular prostheses or screen with lenticular system explained previously.
However, the exploration of three dimensions of space, according to the fourth dimension, remains primarily relating to the run of the images, without being able to relate perfectly to displacements of the observers compared to a fixed image as in Holography.
By this lack from point of view of television in relief requiring a special camera, the observer can thus almost not turn around an animated image of an object being formed in space in front of its flat-faced screen, and by no means enter inside the relief of this image to explore the various aspects of them.
Lastly, if it is admitted that cinematographic images with special glasses allowing a vision in relief of an object fixes successively under various angles deserve the name of images in four dimensions (height, width, depth and time), it can whereas to admit that only one holographic image also allowing a vision in relief of an object fixes successively under various angles also the name of image in four dimensions deserves.
