"Television lines" or TVL, refers to the maximum number of alternating black dots and intervening white spaces that can occur and be distinguished in a straight line whose length is equal to the diameter of the largest circle that fits in the screen or other area of reference.

Photographers, when they refer to lines of resolution on film, count only the black lines or dots in a row in a test pattern, ignoring the intervening white spaces. The term TV Lines was introduced as an advertising gimmick to make TV, which has significantly less resolution than photographic film, seem to have more resolution than it does. In the singular, "television line" refers to the narrowest stripe where several of the same, alternating black and white, can be juxtaposed and still be distinguished.

tv line are the standard measure of an analog tv's resolution.rather dan represent discrete locations on a grid,as PIXELS in a digital frame do,tv lines indicate the maximum number of identifiable changes that can be produced along a single scanline of an analog tv.

television lines are the resolutions on the televison screen that we can see as black and white lines.they refer to the maximum number of alternating black dots and intervening white spaces that can occur. they can be distinguished in a straight line. the length of the line is equal to the diameter of the largest circle that fits in the screen.

well kajol, On a test pattern consisting of closely spaced parallel lines, a TV line is either one black line or one white space that separates two adjacent black lines,As a unit of measurement for resolution, "television lines" (in the plural), or TVL, refers to the maximum number of alternating black.
