Follow-up to call from Verizon yesterday....

 

I had a voicemail from the Verizon Manager, with information I provided, he did make some calls and found out that Verizon has upgraded their transmission of HD with MPEG-4.  

 

From the ressearch arch I did today (Google) it appears most TVs will not decode the MPEG-4.  Again, my research is limited and my knowledge on this is limited.

 

I am evaluating options and I think I am going to try an HD antenna. I do not like the idea of paying for a set-top-box to watch a handful of channels.

 

i do plan to check this thread regularly to see if anyone else gets a better solution from Verizon.

This is really fishy.   Fact check me on all this, but from memory the digital tuners on  legacy TV's are setup to accept either Cable or Antenna HDTV signals -- antenna signals being 8-VSB modulated and cable signals being 256-QAM modulated, but the underlying payload has to be an MPEG-2 payload.  Verizon can't change it MPEG-4, that won't work because that's not the HDTV standard.  (Note:  The reason TV's ask you to select Cable or Antenna on the coax input is so they apply the correct demodulator to the signal.)

 

Verizon closed my ticket without ever reaching out to me with an explanation...simply gave me the explanation "everything is all fixed".  It's not all fixed -- I'm still getting the same lousy 480i signal instead of the native channel's signal which I'm pretty sure is against FCC regulations.  

 

Of course the FCC has been changing the rules a lot lately, so maybe they've relaxed this requirement and Verizon jumped at the chance to save some network bandwidth.  That's just speculation on my part.

I noticed this problem starting in July 2019. I have a Windows PC with 3 tuner cards that I have setup as a personal video recorder (built this machine before DVRs became a commodity). The tuners stopped being able to record the HD channels I had mapped for the local network stations around the beginning of July (I am in the Leominster, MA service area). When I remapped, the only versions of the channels the tuners could lock in were the 480i versions.

 

I originally thought that it might be related to the fact that NBCBoston (Channel 10) started announcing that they were changing their frequency/signal to provide HD quality broadcasting. And, Verizon had made a channel mapping change in anticipation of the 8/2/19 cutover to the new frequency/signal. I was hoping that Verizon would eventually get things working again.

 

Maybe if more people complain, Verizon will address this issue and give us back the HD channels, in the appropriate format(s).

We the customers must remind Verizon Fios management that the original cable service was created decades ago for paid customers to receive standard local broadcast channels without the need to install an antenna. This recent change in their headend violated the original basic cable services. majority of the TV sets released today are not capable to tune and decode MP4 signal. This is the reason you only hear audio, but no video on all HD clear QAM channels due to the fact Verizon is transmitting MP4 in their HD channels. MP2 is the current standard. Someone at Fios management make a decision that take away the basic service from their customers. This is not right for all their consumers, Verizon must fix this issue they created in house. They must role back their changes and continue to transmit standard MP2 format on their clear QAM HD TV signal! The basic clear QAM cable service must be compatible to as connecting a TV set to an antenna to receive all local HD and SD stations.

Verizon has been changing many channels to MPEG4 over the years. Even some of their older set-top boxes don’t support MPEG4. With MPEG4 there is a higher compression rate is will free up more bandwidth. I don’t think any channels will be going back to MPEG2. Unfortunately technology moves fast and equipment becomes incompatible.
