摘要： An adaptive filter calculates a target pixel from an interlaced video signal. The video signal comprises a plurality of frames, each of which comprises an even and an odd field. The filter comprises a quantized motion calculator and a filter selector. The quantized motion calculator estimates an amount of motion about the target pixel. The filter selector selects a filter in accordance with the estimated amount of motion. The filter applies a first weighting factor to a plurality of current field pixels and a second weighting factor to a plurality of previous field pixels for creating the target pixel.

摘要： In a method and apparatus for operating a super-heterodyne receiver, a tuning circuit has a local oscillator for frequency shifting a desired channel to a selected frequency and a controller for controlling the local oscillator. The controller determines for each of a number of identified channels, whether an image signal is present at frequencies in the spectrum that when tuned to a first selected frequency interfere, and is operable to select a modified selected frequency at which interference between the image signal and the identified channel is reduced.
