TV set that could receive most 625 line and 819 line television systems. In England, there were quite a number of TV sets produced that were capable of receiving both monochrome 405 line and 625 line PAL I broadcasts.

of the video content to PAL, whilst leaving the number of lines the same, and the field rate, slightly slowed down in order to accommodate the exact 64 microsecond line length required for PAL.
Newer TV sets would automatically accommodate the 60 Hertz vertical scan rate, and older TV sets needed a manual adjustment of the vertical hold. DVD
