Hi Magnus,
I strongly suspect that the major cause of time lag in TV programs
seen on Digital over-the-air TV is in the TV sets themselves.
My evidence for this is observation of simulcast programs that are
broadcast in both HD and LD on different channels of the same
station. The HD always lag

Modern Science at it's best ...
Some years ago, before the days of Digital TV, I used to compare an OTA
NFL broadcast of a certain game with the cable broadcast of the same game.
The difference was striking.
So, they improved things, now it's all lousy !!

Chuck,
In digital times, the main reason for creating delays is due to the
temporal compression of MPEG-2 and MPEG-4. Production quality is either
not compressed or JPEG-2000 compressed. If you do not compress at all,
delay structure can be similar to that of analog video days. JPEG-2000

We have Brighthouse cable here in Central FL and the delay is horrendous. When
setting up the DVR recorder integrated in the cable box we have to adjust the
start and stop times -/+ 1 minute respectively on a regular basis. The delay is
less than a minute, but the adjustment resolution is 1 min
We have DirecTV with some receivers standard
definition and others High Definition. The
delay is considerably greater on the HD version.
Even OTA HD is delayed considerably, as noted

radio while watching. Sometimes you hear "touchdown"

It is not that they don't care about time sync, it is that they

Because the whole digitization, broadcast, and display process
of digital TV processes seconds to minutes of material at a time,

Here in central PA, ABC was almost exactly 10 seconds slow. That’s about 2
seconds longer than the delay in past years. Even with digital and a direct
network feed, there are a variable number of buffers in the chain.

Oh, they do. Just ask Magnus :-)
The thing is, that video delay in digital systems is hard to keep down
