ABSTRACT:
A method for setting the clamp level of a television signal in which the signal is converted by an A/D converter and quantized with a plurality of quantizers, comprises taking into account the quantization characteristics of the various quantizers in addition to the dynamic range of the A/D converter. The television signal is level shifted so that it is within the dynamic range of the A/D converter and is clamped to a level which minimizes the quantization error of that quantizer which has the largest quantization step size of all the quantizers.
