Abstract
An embodiment improves the quality of sound rendition during restitution of sound and picture originating from a source signal exhibiting temporal drift. To restore the sound and the pictures at a selected fixed picture rate, a picture sequence is calculated at the selected rate on the basis of the pictures of the source signal, and the sound of the source signal is sampled so as to obtain a sampled sound signal having a selected number of sound samples per picture of the source signal. The calculated picture sequence and the sampled sound signal are restored in a manner synchronized with the reception of the source signal. The sampled sound signal is restored without a change of pitch, with an adjustment of timing as a function of the ratio between the selected picture rate and the variable picture rate.
