Back in the mid nineteenth century the first 3D photographic image was created using stereoscopic imagery. Since then, 3D technology has advanced to televisions sets. Nowadays, a 3D TV set can use stereoscopic, multi-view, or 2D plus depth to create a three dimensional image for the viewer.
As of January 2010, at least five television manufacturing companies had announced plans to introduce 3D capacities in televisions sometime before the end of the year. These were expected to be higher end models. Satellite broadcasts in 3D as well as 3D Blu-ray players are also expected.
There is one 3D TV model made in China, and available for sale there. This television features a 43 inch LCD screen and uses a lenticular 3D system that does not require the use of special glasses. This model sells for $20,000.
ESPN has announced plans to launch a new channel in June of 2010 which is entirely devoted to 3D sports with as many as 85 live events in 3D each year. Other channels have similar plans. The Sky UK network intends to introduce the Sky 3D channel in April 2010. This is not to be confused with the South Korean channel, SKY, which, in January, became the first 3D channel in the world.
In most cases the use of special glasses will be required to watch various events and programming. Critics wonder whether viewers will grow weary of having to wear the glasses with regularity and if 3D programming is best left as a “special treat” that folks can enjoy occasionally to keep it interesting. Still, others argue that it will become as commonplace as TV itself and that people will become accustomed to the glasses.
Whether or not the concept of 3D TV sets catches on in the mainstream remains to be seen. There are more and more networks working on programming options and manufacturers that are focusing on adding this technology to future sets. It will all be decided when the general consumer decides whether viewing TV in 3D becomes one of the “must haves” in the world of entertainment.
