| 1. A video encoder comprising:
a receiving module for receiving a video signal, the video signal including a plurality of fields, wherein each of the plurality
of fields includes a plurality of pixels;
a signal processor, operably coupled to the receiving module, the signal processor including:
a signal processing module for generating a processed video signal in response to the video signal, the signal processing
module including a video filter module that is enabled when a filter enable signal is asserted and disabled when the filter
enable signal is deasserted, for filtering at least one of the plurality of pixels of a corresponding one of the plurality
of fields when the video filter module is enabled;
a filter enable module, operably coupled to the video signal, for generating the filter enable signal, the filter enable module
including a motion detection module for detecting motion in the at least one of the plurality of pixels and for deasserting
the filter enable signal when motion is detected in the at least one of the plurality of pixels; and
a video encoding module, operably coupled to the signal processor, for producing an encoded video signal based on the processed
video signal.
