Re: BBC World News cropped For the SD channels it's up to the provider to use AFD to tell any video provider how to display programming on their channel, letterboxed or full screen, if the provider is creating the SD feed from the HD feed.
BBC World News airs SD 16:9 on PBS.
If other providers broadcast BBC World News full screen in SD then that's how the channel is being delivered from the BBC.
