You'd be surprised how many uplinks are unencrypted. Waste of bandwidth
and requires more kit at both ends, more stuff to go wrong. Little
desire for it.
If you have the right kit, know the right settings and know which bird
they're using, you can just slurp them down and record them just like a
broadcaster. More security by obscurity than anything else. If you have
the luxury of a steerable dish and decent decoder, you can scan around
and watch all manner of things, DTH or broadcaster-use. :)
You'd also be surprised that HD transport streams don't require that
much horsepower, if your graphics card can decode H.264 it's offloaded
to that and the rest is just probably MP2 or AAC audio. It's the Yadif
deinterlacing that sucks CPU (to get a proper pseudo-50p reconstructed
image like you'd watch on telly)

OT: most animation doesn't really have a benefit being in anything
above 720p, you simply can't notice it. I subscribe to Crunchyroll and
watch in 1080p simply because I can, but if I alternate between 720 and
1080 there's essentially zero difference for most stuff; the web player
either upscales or I waste bandwidth watching their upscaled encode. The
picture content of most anime doesn't benefit from >720p.
And if people think CBeebies' target audience is going to care about
Peppa the Pig being in 1080 or 720 lines...
For TOTP, if source material is SD from whatever tape format it was
dubbed off, what's the point in similarly offering upscaled SD? A good
quality SD encode at high bitrate will look nicer than HD and is a far
more efficient use of storage and bandwidth.
If it's SD only content it may also be a prior encode republished for
Another example: Dad's Army.
