Here are some plots of percentage of the total mux each channel is occupying as well as the bitrate (average every 0.2 seconds). These first graphs are from 148, which has HDPPV and CBS-W HD as the only two channels on the 8PSK modulated transponder (roughly 43Mbit/s total bandwidth).
Okay, now for the same plots, but from 110. Ignore all the channels listed in the first graph, as NFLHD, NBAHD, HDEV1, and HDPPV all share the same video feed, which is plotted in red.
TNTHD, HBOHD, and HDPPV share this transponder. It is 8PSK modulated as well so the same total bandwidth as at 148. All three channels are 1920x1080i. It just so happened when I did this capture, all three were showing HD content.
I let the video bitrate chart run a little longer since there wa actually some variation in the bitrate (multiplexers doing their job!). Notice we went from 18Mbit/s to 13Mbit/s on the HDPPV channel.
I used TSReader from Coolstf software to produce these graphs. Amazing product for analyzing transport streams.
