576i

Because of its close association with the legacy colour encoding systems, it is often referred to as PAL, PAL/SECAM or SECAM when compared to its 60 Hz (typically, see PAL-M) NTSC-colour-encoded counterpart, 480i.

Analogue television signals have no pixels; they are continuous along rastered scan lines, but limited by the available bandwidth.

Originally used for conversion of analogue sources in TV studios, this resolution was adopted into digital broadcasting or home use.

Motion pictures shot on film are typically intended to be played back at 24 frames per second.

[7][8] This is generally not an issue on modern upconverting DVD players and personal computers, as they play back 23.976023 fps video at its native frame rate.

This preserves the pitch and sample rate of the audio, and the higher resolution of PAL video compared to NTSC, at the expense of more stuttery motion.
