Abstract
An SLM-based video receiver (10) receives a video input on a field-by-field basis at a signal interface unit (11) and passes the input to a processor (12). The processor (12) performs analog-to-digital conversion if the pixel data is analog and also performs other enhancements to prepare the pixel data for loading into a video memory (14). Pixel data from the processor (12), representing a field of pixel data, is stored into the memory (14) for loading into rows of pixel elements of a spatial light modulator (16). The spatial light modulator (16) receives the pixel data in rows. The addressing functions of the spatial light modulator (16) are used to generate additional display rows of pixel data per field. Thus, the SLM-based video receiver (10) displays a video frame having more lines than the field of pixel data.
