The development of satellite television has viewed the digital surge of TV channels, broadcasters, production houses and content producers. This is mainly because cable TV and straight to home platforms have indeed encouraged the frontiers of television broadcasting past all conceivable boundaries and onto a international scale. It is no wonder that TV networks around the globe employ the use of a green screen ^(http://www.indiefilmhouse.com/goto/http://greenscreenhollywood.org/green-screen).

One of the usual methods that are applied in television process development is that of implementing a Green screen ^(http://www.indiefilmhouse.com/goto/http://greenscreenhollywood.org/) in the backdrop of the studio where by a specific program is being shot. This is part of the method of chroma key which deals exclusively with the removing of specific images in the backdrop of the shot and superimposing this with some other picture, which is more suitable for the development. For example, one can use a screen that is green in color behind a broadcaster who is reading out the weather news. When viewers view the plan, the green or blue display as the case may be, is exchanged with a weather map or scenes of certain cities or satellite pictures being displayed instead.

A Green screen is particularly useful for chroma key uses, on account of the point that the natural human skin tone has really very little elements of green in it. This helps in superior top quality of image superimposition along with the replacement of background, without interfering much using the basic view of the broadcaster who is standing in the foreground. If there had been any green tint or tone in human skin, parts of the body might have become invisible when applying the other colored screen, producing the effect very strange and extremely improper and incongruous.

One of the main advantages of applying a Green screen is that it is reasonably simple to implement along with being price valuable. If one were to use a huge plasma or HDTV display screen behind the broadcaster, the impression could be extraordinary, but the price could be far greater than implementing a green screen. In these days of economic recession, where by cost organization stands out as the key, the dice is loaded in favor of using less expensive choices.

One can easily produce a green screen ^(http://www.indiefilmhouse.com/goto/http://greenscreenhollywood.org/green-screen) that can be applied in TV system development. For this, something as uncomplicated as a table cloth can be used. This cloth has to be uniformly painted, to make sure that there are no smudges or uneven areas that will stick out when the show goes on air. One can also use a plain wall that is consistently painted in green to form the colored background. One of the tips to remember when employing such a display is that if the background image is one of trees or forests, green is really a more suitable color to use than blue for the backdrop, while if the graphic is of the sea or the sky, green would not be so apt. Employing a green screen is thus an productive methods of using chroma key procedure in TV program production, which is well-known due to its simplicity and inexpensiveness.
