ABSTRACT:
A hydrid encoder for video pictures comprising a motion estimator, and an inter-intraframe encoding selector which comprise a common calculation module. Known hybrid encoders for transmitting video pictures comprise a motion estimator and an inter-intraframe encoding selector. Due to the required high processing rate the motion estimator and the inter-intraframe encoding selector must have a parallel processing structure which leads to quite a considerable number of components. To this end a calculation module is proposed which can be used in the motion estimator and in the inter-intraframe encoding selector. Use of this invention, for example in hybrid encoders for video telephone apparatus.
