At the Transmitter:
The 16:9 signal from the ISS Camera is squashed into NTSC_DV format, at 720x480. This is subtly resized from NTSC_D1, which is 720x486, for Digital capture (so that the pixel dimensions are divisible by 16).
At the Receiver:
NTSC_DV & NTSC_D1 pixels have an aspect ratio (PAR) of ~0.89 (width/height, making the pixel tall and thin). So for accurate display on a square pixel monitor we can upsample the height (or downsample the width), for a resolution of 720x540 for 4:3. (or 640x480 for downsampling)
Which would be stretched back to 940x540 to restore the 16:9 of the camera! Or of course, stretch first, then downsample to 854x480 as displayed by Tutioune, to keep the picture information without redundant extra pixels.
