"So the broadcast is a 16.9 content, the station broadcasts it into the inside of the standard shadowed off 4:3 screen area, and thus leaving bars above and below the picture.
Yeah Zoom can 'fix it.. But what for?".

Please explain how zooming, a feature which usually cuts off/crops a picture, can restore picture information that's missing in the first place. (Hint: it can't)

Missing credit information (on the sides of the frame) is usually due to the original picture being zoomed and that "reframed" image recorded for future playback.

Below is a link to the wiki page on letterboxing (aka black bars). Scroll down a bit past 1/2 way and read the section titled "Pillarboxing and windowboxing". Windowboxing is the technical term for the explanation that I provided in my response.
