The difference between PAL and HDTV
High-resolution TV is characterised by a signi
fi
cantly higher number of picture lines on the TV set. The
usual European standard PAL achieves a resolution of 576 lines vertically and 720 lines horizontally.
The high-resolution TV provides an impressive resolution, up to
fi
ve times higher than the usual
PAL standard TV, and hence delivering more detail sharpness and responsiveness.
A HDTV picture can contain up to
fi
ve times as many picture points, that is, approximately 2 million pixels
compared to a conventional PAL picture with only approximately 400,000 pixels.
Worldwide there are currently two HDTV standards, based on the two formats 1080i and 720p. The two
standards differ in the number of picture lines and in the transmission procedure. To the human eye, the
difference between the two HDTV standards is hardly perceptible; whereas in comparison to the PAL
system, moving pictures look much more dynamic in HDTV. Transmission technology and reception
equipment will be able to handle both standards in the future.
