Patent ID: 7444034

Claim:
An active cable, comprising: an interface configured to receive a video signal comprising a certain format; and processing circuitry configured to process the received video signal, wherein the processing circuitry comprises a multi-dimensional image data enhancement device, the multidimensional image data enhancement device comprising: a convolutional low pass filter configured to convolutionally filter image data in a plurality of dimensions; a feedback loop coupled to an output of the convolutional low pass filter, the feedback loop configured to receive filtered data from the output of the convolutional low pass filter; and a multiplexer, coupled to the feedback loop and an input of the convolutional low pass filter, the multiplexer configured to multiplex image data and filtered data under the control of a control signal, the control signal configured to indicate when the image data comprises blanking data and to control the operational rate of the convolutional low pass filter.
