Sounds to me like WIVB-DT had the settings on their encoders set properly.
Maybe Nick and family thought all of those blocking artifacts on the
graphic transitions were [art of the special effects...
;-)
We had several features like that in the first Grass Valley DVEs;
these included quantization effects and blocking effects (matrix
wipes). We nicknamed them "defects"
I just replayed the first 10 minutes of the game on my Cox DVR. The
worst artifact came from the graphics swoops, especially at the end
of replays and team introductions. The picture remained block and
quantized for about 1 second at the end of these "swoops." I also
noticed a number of shots with problems (mostly close ups with rapid
motion).
On the plus side, it looks like most commercials were produced in HD.
