An apparatus for converting a video input signal representing an image from a first format to a prescribed second format. The apparatus comprises the following elements: a sync separator (30) for extracting a synchronization (sync) signal from the video input signal; a section (32, 34, 36, 40) for generating a sample clock signal on the basis of the sync signal and the said prescribed format; a sampling section including A/D convertors (18a, 18b, 18c) for sampling the video input signal in accordance with the sample clock signal to obtain a prescribed number of samples per line of the image; a section (20a, 20b, 20c, 22) for combining the samples of at least two different lines to obtain a prescribed number of new lines each of which comprises the said prescribed number of samples per line; and a filtering section (17a, 17b, 17c) for filtering the video input signal so as to effectively horizontally average each line of the image.
