Same-parity fields are used to improve the accuracy of motion estimation. It estimates the motion by comparing the sum of absolute block difference(SAD) between 4 fields with the threshold of motion.

Absolute truth isdoomed because the search to ferret it out would ultimately be so consuming asto eradicate trust, which is the far more solid building block of humanrelationships.

In the absence of force when the fuel block can be automatically extinguished, absolute safety.
