Abstract

Transformation of computer graphics images to the RS170A television format by a new digital video standards conversion technique is described. Nominal resolution of incoming images is 1280x1024 pixels. Output image resolution is 762x483 pixels. To avoid aliasing effects, images are low-pass filtered prior to resampling in the horizontal and vertical directions. A range of '1000-line' images with different dimensions and timing parameters may be accommodated by adjustment of stored coefficients through the interactive user interface.
