Many thanks, Gav.
However, that leads me to ask why a picture is transmitted as a 720x576 image and then stretched to a 16:9 aspect ratio later on?
16:9 pictures and 4:3 pictures are both 720x576.

Anamorphic widescreen is recorded using a horizontal-squeezing technique. If they are played on standard 4:3 television without adjustment, the anamorphic image will look horizontally squeezed; the actors will look thin and tall and a circle will be squashed to appear as a vertical oval. Changing the playback equipment to use the "fill" or "4:3 letterbox" setting will stretch the image horizontally to exactly reverse the squeezing used during recording. This allows the movie to be viewed in its original widescreen format. If the playback screen has a 4:3 physical format, typically black letterbox bars will be inserted above and below the image to fill the empty space. If the screen has a 16:9 physical format, stretching the image back to its original rectangle shape will typically fill the screen
