This is a screenshot of a video playing. You see a normal 16:9 video like you would expect to see in any modern video solution. This - the aspect ratio that the viewer sees - is what is called the display aspect ratio or DAR.

From the illustrated parameters, we see that DAR = 1280:720 = 16:9 = 1.7777777777777777777777777777778.
