cheap in car dvd players

Television is recorded in the same type of frames. Then it ' s broken down to be transmitted in a signal. When the signal is received by your television, it is reassembled in sections, or stripes. These stripes are reassembled in two different sets, from top to bottom and left to right across your television screen. To explain this concept more clearly, imagine window blinds that are partly open. The actual blind pieces are one set of stripes and the space between the stripes represents the second half of stripes. In a TV transmission, the stripes of set one are laid in before the second set is laid in. This is called an interlaced display. Although it sounds like it would take some time, all of this happens in the fraction of a second – 60 of the fields or stripes are displayed per second.

DVD players and DVDs have used this same technology because of the fact that TVs displayed pictures this way. But with the advent of digital and high definition television projectors, display technology has changed, leading the way for DVD technology to change as well. These high performance TVs and projector screens receive and display signals in full progressive frames instead of stripes. And 60 full frames are displayed per second. Meaning even more detail can be included in the same amount of time, resulting in pictures with less flicker or picture distortions. Progressive scan DVD players work by sending DVD signals in the same progressive format.
