INT is_SetDecimationMode (HIDS hf, INT nMode, INT nDecimate)
Description
is_SetDecimationMode() sets the number n of frames or fields which should be thrown away (PAL: n of 25 frames/50 fields; NTSC: n of 30 frames/60 fields). The unused frames or fields are not transferred over the PCI bus which gives a reduction of PCI load.
