Abstract: A method and apparatus for improved processing of digitized moving pictures. A motion vector for field frame processing is produced using fewer pixels from the source image and fewer coefficients than are required by the prior art. This allows field frame motion to be processed using no more pixels than are required for other forms of motion processing, which in turn reduces the circuitry and processing time required. A reduction in the pixel processing requirement allows less circuitry to be used for this processing with equivalent throughput. Alternatively, it allows for improved throughput with an approximately equivalent amount of circuitry.

Abstract: The present invention provides a tethered bridged metallocene compound in which the tether typically comprises a segment of the formula —(R2)d—(CH2CH2)e(CH═CH)f wherein R2 is an alkylene or phenylene group, and d, e and f are 1 or 0. One end of the tether reacts with a silane bridged metallocene compound and the other reacts with the support. The activated metallocene compound is capable of producing a polymer having a narrow molecular weight distribution.
