Playing back interlaced video from a DVD, digital file or analog capture card on a computer display instead requires some form of deinterlacing in the player software and/or graphics hardware, which often uses very simple methods to deinterlace. This means that interlaced video often has visible artifacts on computer systems.

For example, writing to a CD at 8× will be twice as fast as writing onto a disc at 4×. [2] There are two main types of disc speed, which are the angular and linear velocities. If the disc spins at a constant angular velocity, the linear velocity is 2.4 times higher at the outer edge.
Deinterlacing is the process of converting interlaced video into a non-interlaced or progressive form. Interlaced video signals are commonly found in analog television, VHS, Laserdisc, digital television when in the 1080i format, some DVD titles, and a smaller number of Blu-ray discs.
In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
The DVD-Video spec appeared when people were still using interlaced CRT-based TVs. For current generation of progressive-scan TVs there is no need to output interlaced video. Thus, DVD players are using these flags to figure out if the content is progressive, and if yes, they output it as progressive.
In video technology, 24p refers to a video format that operates at 24 frames per second (typically, 23.976 frame/s when using equipment based on NTSC frame rates, but now 24.000 in many cases) frame rate with progressive scanning (not interlaced). Originally, 24p was used in the non-linear editing of film-originated material.
An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT). Closely following the ITU-R Rec. 601 standard, DV video employs interlaced scanning with the luminance sampling frequency of 13.5 MHz. This results in 480 scanlines per complete frame for the 60 Hz system, and 576 ...
