Abstract:
Apparatus for providing data at resampled rates comprising:a signal input port; a multiplexer having first and second input ports and an output port said first input port being coupled to said signal input port; a delay element for delaying data corresponding to one horizontal line having an input port coupled to the output port of said multiplexer and having an output port coupled to the second input port of the multiplexer; an interpolator having a first input port coupled to the output port of the delay element, a second input port coupled to said signal input port, and an output port at which resampled data is available, said interpolator scaling data available at its respective input ports and combining the scaled data to provide said resampled data; and a controller coupled to a control input port of said interpolator for selecting respective scale factors and coupled to a control input port of said multiplexer for conditioning the multiplexer to selectively recycle horizontal lines of data.
