Whether this is true or not you'd need to have access to the original signal from the broadcaster and then compare that identical signal (including it being the original/same program) to what you are getting via Verizon FiOS. You might be able to do this sort of comparison with major channels like ABC, CBS, NBC etc using an OTA signal with your own antenna and tuner but even then how can you know that the broadcaster is TRULY sending the same quality signal to FiOS that it is broadcasting over the air?
I'm just questioning how you can show unquestionable proof that FiOS PQ is degrading and it's Verizons fault.
It is no longer true that Verizon passes on signals untouched. In many cases, channels are being broadcast in MPEG4 h.264 format, which Verizon usually transcodes to MPEG2 for compatibility with 6-series STBs. Some MPEG4 channels are converted to MPEG2 with a lower bitrate, allowing Verizon to put three such HD channels into a single QAM slot (as opposed to their customary two HD channels per QAM slot).
Verizon is currently performing a "soft" migration towards MPEG4--all new low-demand HD channels are now in MPEG4, and customers with 6-series boxes who subscribe to those channels are being allowed to swap them for 7-series boxes free of charge.
Verizon still generally has better PQ than the other guys, but it does do transcoding now where it did not before. Presumably this situation will last until there are so few 6-series boxes in the system that Verizon can fully transition to MPEG4 h.264 broadcasting.
