Certain Freeview SD channels with HD counterparts generate "Watch in HD" on-screen pop-ups, depending on the UI of the TV/set-top box (receiver).
Apparently this depends on a flag sent in the broadcast stream and the interpretation of those flags by the receiver.
Strangely, (in London) these channels send the flag: BBC1, BBC2, CBeebies, C5.
And these don't: CBBC, BBC News, ITV, C4, Quest.
And neither do RT, QVC, QVC Beauty, if anyone cared.
Why are children above infancy not being encouraged to use HD?
Why are news junkies not being encouraged to use HD?
Why don't ITV, Channel 4 and Quest, which all show sports programmes that would benefit from the better motion quality of HD, send the flag?
Channel 4 is a keen user of the Book Me feature on several of its channels, so they're obviously not averse to metadata.
