Abstract:
A digital video-processing unit for processing an input data signal to an output data signal for an output device, the input data signal representing a sampled image comprising a number of lines, said video-processing unit comprisingfirst memory means for storing the input data signal, processing means for processing the stored input data signal to an output data signal, second memory means for storing the output data signal prior to supply to the output device, a memory manager being coupled to the first and second memory means and to the processing means and being arranged to transfer the input data signal to the first memory means, to transfer the stored input data signal to the processing means, to transfer the output data signal to the second memory means and to provide the stored output data signal to the output device, characterized in that the processing means is arranged to process a data set comprising a first set of samples corresponding to a block of the sampled image, the first set of samples being composed of a predetermined first number of samples selected from each one of a predetermined second number of lines of the sampled image, the first number of selected samples of each line being smaller than the total number of samples of a line.
