Abstract
In this paper new discrete quasi-interpolants on the real line are defined with good error constants for enough regular functions. Some oversampling is permitted in order to have some freedom degrees and so a minimization problem is established. This problem has always a solution that can be characterized in terms of the best uniform approximation by constant functions to some appropriate splines. Some examples are given and the error is analyzed.
