A few years ago, multichannel sound was considered the limit of realism, and video equipment manufacturers, having learned to achieve the highest image clarity and the most realistic color reproduction, could not offer anything more. It seemed that there was nowhere to go any further, but today the world has crossed the threshold of the three-dimensional era. Finally it became possible to watch surround video at home, and not just in cinemas. The release of the relevant content has already been taken up by the largest publishers from the world of games and cinema, and television companies have started shooting sports competitions in this format. Moreover, the size of the technology remained the same, it did not lose at all in convenience and mobility. Thanks to the use of the latest technologies, in particular organic light-emitting diodes, the thickness of TVs does not exceed three centimeters. So, ensuring the maximum effect of presence, the technology itself is becoming less noticeable.
