The normal input source of a DVD is 480i.480p. The output remains the same when played on a standard DVD player. But when played on a High Definition player, output is scaled up to 1080i/720p, giving you crystal clear picture and sound. This process is called scale up processing. De-interlacing algorithm process allows each frame of a video captured at 30 FPS to be split into two separate frames at 60 FPS. Each frame represents one field of video. The process permits the temporal content to be removed from the image.
