Below is the reply I got back from ABC/NBC: - let me know what you guys think before I respond (to see my original email see my previous post)
Thank you for your comments about WJXX-DT, our ABC digital
outlet in Jacksonville. WTLV-TV (analog NBC), WJXX-TV (analog ABC),
WTLV-DT (digital NBC) and WJXX-DT (digital ABC) are all switched under
automation control from our studios in Jacksonville. We employ a team of
operators and engineers to monitor and oversee our technical operations.
It their job to ensure that our transmissions comply with the FCC
regulations and our internal technical standards. That function includes
switching away from a source that does not meet those standards.
As you so correctly noted, HDTV is a new technology and as such,
the reliability and stability of network transmissions is not as good as
we see in the analog world. ABC is the only network to use the 720
progressive HD standard and more development work has been put into the
more popular 1080 interlaced standard. As we have worked to resolve the
HD issues, we have noticed that the ABC HD transmission is more prone to
failure than the NBC HD feed. Also, remote or live telecasts such as
parades and football present more challenges than in-studio, taped
events. That is not to say that taped event do not have problems from
time to time, but it seems that live events are more susceptible to
In the event of an HD feed error, our operators will switch to a
SD feed of the program rather that have the HD feed fail on the air.
That is why some programs are not passed through. It is not that they
"forget to flip the switch" or are not paying attention, they are
attempting to provide our viewers with the best picture and sound
available at the time.
We are working with all the parties to resolve the issues with
HD including ABC, NBC, the transmission equipment manufacturers,
encoding equipment manufactures and transmitter equipment manufacturers.
We have already resolved a number of issues and are hopeful that new
software releases to be installed this week will resolve most of the
remaining instability issues in our HD circuit.
Let me assure you that we are committed to providing our viewers
with the best HDTV experience possible and we are working daily toward
Again, thank you for you comments.
