Table of frequency (MHz) vs amount of stuffing (Mbps) on each frequency. Individual values not particularly interesting, but the worst offender is 36.2 Mbps stuffing (out of 50.69 Mbps total for that multiplex).

For those interested in numbers:

• 30 multiplexes of 8 MHz, 256-QAM, with bitrate of 50.69 Mbps each
• 1 multiplex of 8 MHz, 64-QAM, with bitrate of 38.01 Mbps

Across all of those, approx 574 Mbps is wasted. That means you can drop 11 out of 31 multiplexes […]

They are in fact planning changes in a few weeks which are supposed to remove SD versions of channels to "give more bandwidth to internet", so here's to hoping they'll also consolidate the muxes and maybe change the bitrates a bit? Will be interesting to see :>

Stacked graph of bitrate (vertical axis) over time (horizontal axis). The total bitrate sums up to about 50 megabits per second. The vast majority of it (36 megabits per second) is taken by null packets/stuffing.

Out of curiosity captured transport streams of my cable TV provider (who also does internet over DOCSIS), and it's so sad. You can see the effect of TV channels going away, and the space they previously occupied remaining unused.

So much stuffing that […]
