HD television is captured and stored as a component signal using 20 bits. The separate bits are used in such a way that the data can store what is effectively a 30 bit signal so there is a theoretical 1 billion colors available.
HD video in the studio requires a bandwidth of 1.5Gb (1500 megabits per second) and for transmission, this needs to be compressed to signals that are around 5 - 6 megabits. In doing this compression, much of the color information can be lost so 1 billion colors are never seen on a domestic television. That is rarely a problem as our color perception means we are quite happy watching programs with much less color information.

How does high difinision tv work?
The answer starts with standard definition television because HD is based on the principles of standard definition. What follows is a greatly simplified description of both and a lot of detail has been left out, but the principles are accurately described. An image is broken down into many individual lines. Each line has hundreds of individual colors. Each line is broadcast one by one and when they reach a television, the lines are put together in order to create a complete image. Standard definition television is created using 480 lines or 576 lines. High definition uses 720 or 1080 lines. The way the images are delivered is much the same as standard definition but the way the colors are encoded provides a better color quality than conventional standard definition. High definition needs far more information to create an image than standard definition, about 5 times as much in fact. This means that all components that are used in high definition television need to operate at much higher frequencies to be able to handle the extra information. It is this higher frequency operation that is perhaps the biggest change between standard and high definition systems.
