A substandard of PAL used by some countries, utilising 60Hz instead of 50Hz refreshing frequency. Some multi-standard equipment can take American NTSC and transcode the signal into PAL format. When operating in this mode most of them do not output a true (625/25) PAL signal but rather a hybrid of PAL and NTSC known as PAL-60 (or 'pseudo PAL') with "60" standing for 60 Hz, instead of 50 Hz. Some video game consoles also output a signal in this mode. Most newer television sets can display such a signal correctly but some will only do so (if at all) in black and white or with other problems.
A PAL-60 signal is similar to an NTSC (525/30) signal but with a PAL chrominance subcarrier at 4.43 MHz (instead of 3.58) and with the PAL-specific phase alternation of the red colour difference signal between the lines.
