ABSTRACT:
In a system for forming a decompressed digital video signal representative of a digital video image, first and second pixel signals respectively corresponding to first and second pixels are provided, and first and second quantized pixel difference value signals respectively representing first and second quantized pixel difference values are provided. First and second values corresponding to the first and second pixel signals are loaded into a first register of a non-parallel processor, and third and fourth values corresponding to the first and second quantized pixel difference signals are loaded into a second register of the non-parallel processor. First and second current pixel values are concurrently generated by adding the contents of the first and second registers in a single operation, wherein the quantized pixel difference values have been predetermined to ensure that the additive result of the first and third values does not spillover into the additive result of the second and fourth values. A decompressed digital video signal is generated in accordance with the first and second current pixel values.
