Question regarding resolutions

Hello,

This is not related to Magix products, however I have a question to ask some experts here.

I understand that Freeview broadcasts for SD channels is 544x576, but why is it that if you watch the same programme via a streaming service, the resolution is 1024x576?

So really my question is whether there is much difference in quality between 544x576 & 1024x576? The overall quality does seem to look a bit better compared to how it looks on Freeview.

Jak, the Freeview videos would have the 16:9 flag set in the file so that the pixels display at the 16:9 "shape". That means the 544 horizontal pixels are stretched to cover the 1024 area; they are not squares, they're effectively=y rectangles.

As for the better quality, I surmise that that is because, for the square-pixel stream video, you're actually getting 1024 pixels across instead of 544 stretched. That would allow more detail.
