Abstract: An apparatus comprising a video decoder configured to receive a composite video signal modulated on a sub-carrier signal and having a luma component and a chroma component, the video decoder configured to perform a motion detection operation on the luma component and the chroma component in a plurality of frequency regions respectively. The video decoder includes variable threshold logic, coupled to the video decoder, and configured to provide a unique threshold value to the video decoder for each of the plurality of frequency regions respectively. The apparatus also includes a sub-carrier detection logic, coupled to the variable threshold logic, and configured to detect the sub-carrier signal by checking both spatial and temporal characteristics of the sub-carrier detection logic.

Abstract: A digital filter includes a plurality of connected component digital filters. Control signal generation circuitry is configured to receive a tap output signal from each of at least some of the component digital filters and to process the received tap output signals to generate a control signal to output from the control signal circuitry. Output processing circuitry is configured to process an output of one of the plurality of component digital filters, based on the control signal generated by the control signal circuitry, to generate an output of the digital filter. The processing of the received tap output signals by the control signal generation circuitry may be, for example, programmably configurable.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for distinguishing false motion from true motion, in a video signal that is received by a television set. The video signal is received at the television set. The video signal includes a luma component and a chroma component. A motion detection operation is performed for each of the chroma component and the luma component in several frequency regions of the received video signal. Each frequency region has a unique, adjustable threshold value for distinguishing false motion from true motion, that is dynamically adjustable based on the incoming video signal, and as a result the motion detection accuracy is improved and image artifacts are minimized in an image that is described by the video signal and is to be displayed on the television set.
