A very common example of '240p over component' is playing PlayStation 1 games on a PlayStation 2 which is hooked up with a PS2 YPbPr cable. The input stages in some newer non-CRT TVs & monitors were not properly designed and do not accept 240p timing signals over the YPbPr component video connection (deemed '240p over component'). Another name for progressive is 'non-interlaced'. The more common term used for this type of signaling is '240p' (p = progressive).

Nintendo's name for this type of scanning is 'double-strike', because the same set of lines are drawn twice within one scanning cycle while the lines that would normally be drawn in-between them are absent (or not 'struck' at all). To accomplish this, the 'special timing signal' mentioned above is slightly changed to tell the CRT to not alternate between its odd and even lines. This means that the other field and its entire set of lines are completely ignored.

The solution is to assume that a standard interlaced half picture (480 divided by 2 = 240) is a full picture, and simply display this picture at a normal field-rate of 60 times per second. Older game consoles didn't have the technical capabilities of generating a full 480 line picture. However, the fluid motion desired in video games requires a faster framerate of 60fps. A full picture is considered to be consisting of about 480 lines, so we call this 480i (i = interlaced). The lines are drawn in an alternating fashion and there's a special timing signal sent with the video content to tell the CRT to do this alternation. This process is repeated, and it's quick enough that our eyes don't notice the rapid flickering.to a certain extent. The fields are drawn in such a way where the odd-numbered lines are drawn (evens are skipped), and once the bottom of the screen is reached it begins from the top again, but this time drawing the even-numbered lines (odds are now skipped). This alternating pattern is constantly repeated and, therefore, results in a full picture 30 times a second (hence, 30fps).Ī CRT draws a picture line-by-line from left-to-right and then top-to-bottom. These half picture fields are displayed on the screen at a rate of 60 times per second (or 60Hz). This meant that the TV displayed half the picture (called a 'field') in one pass of the screen and the other half (another field) on the next pass. CRT televisions were designed for interlaced content at 30fps (frames per second). Back in the day, this was not a problem because the video signals directly drove the CRT in your television. Older video games and computer systems output video signals that don't completely conform to normal video timing standards. Throughout the following page, we assume we're dealing with North American or Japanese signalling (NTSC), but when dealing with PAL content the numbers are the only things that really change. The History and Technical Mumbo Jumbo We will try to explain this esoteric topic as clearly as possible.
