All video assists are based either on PAL or NTSC video
systems, with a xed video frequency of either 25 full video
frames per second with PAL or 29.97 full video frames per
second with NTSC. The speed of the lm camera on the other
hand can be selected over a wide range. At every lm speed
which is different from the video frequency, the IVS has to add
repeated video elds to compensate for the different frame
rates.
