ABSTRACT:
A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time period for one incoming field. The progressively scanned image is formed from "real" and interpolated lines of luminance. In this arrangement a speed-up processor is provided for generating the high speed output. The speed-up processor incorporates an input sequence device, a storage device and an output sequence device. In the implementation the input sequence device rearranges the original data stream such that samples from the input data stream are stored in the rearranged sequence. The output sequence means selects the samples from the storage device such that the output samples are restored to their original sequence and provided at the faster rate.
