Recently, there's developed a fashion for, when they want to show two
screens, to have the left one overlapping and cutting into the right
one:

That must be fun for an audio describer then.

The web site is up here, and if you can't get it down, use the or code on

Very good point! I _think_ it's usually upper right for the BBC, but I'm
not sure about that. Left for Sky - again, only from memory.

I _think_ if your smartphone (or whatever you use to read the codes) can
see all of the screen, it will _probably_ extract the URL OK (I'm pretty
sure all a QR code does is link to a URL), but I'm not sure about that,
not currently having one: can anyone verify that for Brian?

The QR code is read as a text string after decryption and decoding. This
is now often a URL, but it was originally used for product
identification where a barcode did not have enough characters available.

The error correction in the QR code data and the reading programs is
very good.

Thanks; interesting. I think nowadays it's virtually always used as a
URL - that's certainly the impression given by those drawing attention
to them. (Though they don't usually actually clarify to that extent.)

I know - hence the abuse of putting a logo, hole, or similar over the
middle. Can you confirm what I suggested to Brian - that for an
on-screen one, provided your smartphone (or whatever) can see the whole
screen, it'll decode a QR code that's on it somewhere?

That depends on the camera quality and how far away you sit. The camera
has to see each "dot" using more than one pixel, ideally four. The dot
size can also vary with the amount of data. Freeview SD has 720 x 576
pixel resolution, HD is 1920 x 1080 (From memory), and as I've not
noticed how big the QR code is, I can't be sure how close you need to
get with the average phone camera.

I would hope that someone has sat at the usual distance from the screen
with a smartphone to check that the QR square is big enough to read on
an HD screen.

At best yes, at worst channels like Sky News etc only broadcast on there
at 544 x 576

I know, but I was hoping the broadcaster or programme creator would have
done it, if only to avoid complaints.

Its QR until spellcheckers get hold of ot.
The new codes are in fact Navilens ones which can work from across the
room.

Navilens is better again, and the phone can even tell you the direction and
how far away you are, counting down as you approach it. Very good for
products on a shelf, provided of course they don't stick something over it
in the store.
