If you were in the stadium I expect the clock would have agreed with
your watch, most of the the delay if watching on digital TV will come
from compressing it before transmission and decompressing it after
receiving to display the picture.

Walking around the TV section of a large department store recently,
SWMBO noticed that the TVs all seemed to be showing the same channel
at slightly different times - some were a good second out.

That is due to the TV's internal delays in decoding the digital signal
plus maybe differences in the time the TV's were powered up (not sure on
that last).

nope. Its purely how much buffering they do on the signal. Decoding a
compressed video always takes some time, and to an extent,the more time
it takes the better a job you can do.

Our Sonyt STBS are about a second and a half out of synch with 'real
time' and the DTB adapter on this computer is more like 15 seconds.

The wifes DTB on her Mac is about 5 seconds delayed
