Objection to the last sentence: ... for a PAL system 625 lines, and for the NTSC system 525 lines. Not necessarily... PAL and NTSC are color TV systems. They can be apllied to all broadcast systems. There may be a 625 line NTSC and 525 line PAL. In the above sentence the word PAL should be replaced by system B and the word NTSC should be replaced by system M.

TVL is independent of field-of-view and size of display[edit]

I think the following two sentences are either confused or wrong.

> "TVL also makes a variation on horizontal angle of display from a video camera, i.e. The more the TV Lines depending on the size of lens, the smaller/narrower the angle of coverage but better picture quality."

> "TVL also makes a variation on an angle of display from a video camera, i.e. The more the TV Lines depending on the size of lens the smaller the angle of coverage but better picture quality."

I would say that TVL is independent of the size of a display panel, and also independent of the field-of-view of a analog camera. Glueball (talk) 06:21, 1 August 2011 (UTC)

You are correct. The lens focal length and sensor format determine the field of view. Fixing. Schitso (talk) 15:39, 25 July 2012 (UTC)
