The computer industry argued that progressive scanning is superior because it does not " flicker " in the manner of interlaced scanning.

The 405-line system adopted the ( at that time ) revolutionary idea of interlaced scanning to overcome the flicker problem of the 240-line with its 25 Hz frame rate.

The computer industry argued that progressive scanning is superior because it does not " flicker " on the new standard of display devices in the manner of interlaced scanning.

The " 24 " refers to the frame rate ( 24 frames / second ) and the " p " stands for progressive scanning ( as opposed to interlaced scanning ).

In the world of standard definition video, which traditionally has been using interlaced scanning, it is also known as " quasi-interlace ", " progressive recording " or " movie mode ".

However interlaced scanning does not work as efficiently on newer display devices such as Liquid-crystal ( LCD ), for example, which are better suited to a more frequent progressive refresh rate.

The " 1080i30 " or " 1080i60 " notation identifies interlaced scanning format with 30 frames ( 60 fields ) per second, each frame being 1, 920 pixels wide and 1, 080 pixels high.
18.
The " 1080i25 " or " 1080i50 " notation identifies interlaced scanning format with 25 frames ( 50 fields ) per second, each frame being 1, 920 pixels wide and 1, 080 pixels high.

In fact, interlaced scanning can be looked at as the first video compression model as it was partly designed in the 1940s to double the image resolution to exceed the limitations of the television broadcast bandwidth.

For their part, the consumer electronics industry and broadcasters argued that interlaced scanning was the only technology that could transmit the highest quality pictures then feasible, that is, 1080 lines per picture and 1920 pixels per line.
