3D TV and 3D holographic TV are the technologies of the future TVs. While the world is waiting with baited breath the arrival of 3D TV, another technology is creating waves and promises to be as realistic as 3D TV. Yes, we are talking about 3D holographic TV. We all are aware of 3D TV as we have been privy to may 3D films already screened in theaters where the viewers are made to wear special 3D glasses which increase the 3D effect of moving images. What is the difference between 3D holographic TV and 3D TV, and why is the world so excited about it?
While 3D TV relies on making use of special equipment like a Blu ray player, 3D holographic technology makes use of images that are projected on the viewing area and then viewed from all angles by the viewer. It is clear that 3D TV will make the viewers wear special 3D glasses without which it is not possible to produce 3D effects on TV. Scientists are trying hard to obliterate the need of 3D glasses as they prove to be a stumbling block in the popularity of 3D TV. This is where holographic TV scores over 3D TV as it does not rely on special glasses at all. In fact, holographic TV is certain to revolutionize the way TV has been viewed so far as instead of mounting a TV on a wall, the beams can be projected even on the floor or on to any area which is suitable for viewing.
The real stumbling block so far in the production of 3D holographic TV is the refresh rate as the present rates are not good enough to give the viewer a real sense of motion. But scientists are working on this problem of refresh rates and are certain that they can come up with refresh rates that will allow the user to view almost real life pictures.
Another hurdle in the development of 3D technology is the actual dearth of 3D content as far as programs in 3D are concerned. No standards have been set as far as encoding of 3D content is concerned. This makes it confusing to differentiate between the features of different brands of 3D TV.
Summary Both 3D and 3D holographic TV are the technologies of the future and both are facing hurdles at the moment. Holographic TV promises to be a step farther than 3D as it allows the user to project the beam anywhere in the room thereby enhancing the real feeling of watching a sports program is concerned. |
