There is a "feature" in the firmware which forces any scaling of widescreen broadcasts to retain the aspect ratio, while (proper) 4:3 broadcasts can be scaled arbitrarily. And the BBC transmits 4:3 programmes in a widescreen frame, so they aren't proper 4:3, and so they are also forced to retain the aspect ratio when scaled. This may have been added for (perceived) issues involving PiP, but to me it seems that that's still done wrong anyway, so it's a bit moot.
Anyway, [Ws] WidescreenScaling disables this restriction and allows arbitrary rescaling of widescreen broadcasts. This is most easily tested using VTS in the Extended Command Console (see here for example usage). |

In the decription of VTS it is stated that: VTS mainSub(1,0) x y w h
... but I presume that w=<720 and h =<576, so it is only possible to zoom out - not in any way possible to zoom in ??? |

I had to delve into the scaler code to uncover the widescreen restriction -- there's lots and lots of it, and it's very complicated stuff (but probably trivial stuff to a graphics expert). In the end I had to attack the search from all directions (following the code down through the firmware calls, checking effects on EMMA registers, working back up from firmware references to those registers, and monitoring firmware data structures). Clearly, I did find the code that did the restriction, but apart from that specific bit I can't say that I fully understand the stuff around this area. 
It's quite common for there to be routines in the firmware that aren't used. This will be when they are in the same compilation unit to code that is used, so the linker can't elide them. So it's certainly possible that there are more general routines for using the scaler, but I'm not sure I could find them... |

| Can you please explain the 'before' and 'after' of this patch please (if relevant) so that i can see it 'working'. I've applied it but don't know what to look for! |

| As in the first post, use VTS (or VS) in the Extended Command Console on the TF58x0, or write yourself a TAP that uses TAP_Channel_Scale(), or maybe try one of the TAPs that does widescreen/letterbox fiddling (which complain about this "feature"). |

| Thanks, I think I understand; So now DumbWideScreen TAP can, when modified, turn the BBC 4:3 to 4:3 Magnified to cover the whole screen rather than with black bars. |

| Sorry to sound stupid, but what's the difference between this and [Af]? |

| I'm considering installing both the Ws and Af patches on my firmware but am wondering whether they will make a difference for me: I watch the toppy via scart (though I may soon move to component) on a 26 inch wide-screen lcd tv, I have the tv set to 'autowide' so that all toppy output is forced into wide-screen. Please could anyone advise whether these patches will make a difference for my set-up? Thanks in advance for any advice. |

I am not using these 2 patches yet, but if this sort of idea would work, then it would save me another TAP running.
Thanks,

That's as good as it gets. The link to the patch is part way through the thread.
I use WSSKiller to force 4:3 broadcasts into a 16:9 frame. This works for everything except 4:3 on BBC channels, which get squished. Installing the [Af] patch fixes the BBC 4:3 without affecting anything else.
Now the TV stays in 'wide' mode all the time, and all 4:3 broadcasts *appear* to be in pillar box mode, but are actually widescreen with black bars applied within the Toppy. |
