Found a thread on avsforum where NBC's engineers are participating. Turns out it would be very simple for them to include a second audio stream without the commentary. In addition, this has apparently been done by some European broadcasters.
I would like to even propose we expand the standard a bit here, to indicate when two streams are "mixable." If Stream 1 had the full audio, and stream 2 had it without commentary, one could also mix these streams, to effectively adjust the volume of the commentary if your equipment knew enough to do so. You could also subtract them if you wanted just the commentary. In a perfect world, each audio channel would come in its own stream so that you could mix yourself, and edit out Scott Hamilton for example, but that's not likely to happen.
So let's encourage them to do this for all sports. Give HD viewers a true "being there" sense. Other interesting things learned: The SD stuff is being shot with widescreen PAL (625 line, 50hz) cameras, cropped and coverted to 525line 60hz for SDTV, upconverted with no need for crop for 1080i60hz viewers.
Sport inflation: It keeps going. Just too many sports. I must admit I am of two minds on Snowboardcross. On the one hand, sports where people physically race one another (like in track) are much more exciting to watch. On the other hand, both Snowboardcross and short-track speed skating tend to have too much luck in them because of this, as people both fall, or are hit by those who fall. Those who are innocent have been getting free passes from the heats (fair) but are just out of luck in the finals.
At least there is no "program component." In spite of Figure Skating's efforts to revamp the terrible judging system which ended in scandal last time when a French judge was bribed to reduce the score of a Canadian pair, it seems that "reputation" remains a huge hidden component in the scores.
It probably wouldn't get the audience, but I would switch figure skating to a pure, non-judged event like high-jump. You keep raising "the bar" (difficulty level on a series of jumps and moves) until only the gold medalist can do it. You would end up with more medals (at least one for the Axel and Toe Loop, or just a general for toe jumps and edge jumps.)
It's not that the dances and choreography aren't pretty and fun to watch. It's just that they are artistry rather than pure athletics -- and thus depend on reputation too much.
These olympics are doing poorly in the ratings. I would have figured with all the HDTVs out there the reverse would happen. Of course, I watch with MythTV. It would be unbearable to watch these games without Myth or Tivo or similar, and most HD users don't have those things.
Interesting issue with Ice Dancing. One of the teams featured a U.S. man and Canadian woman, who could not compete in 2002 because of this. They competed this year after some lobbying got U.S. citizenship for the woman via act of congress. I wonder if we'll see more Olympic gamesmanship with modification of citizenship rules. (It's been common for years for people with dual citizenship who can't get on one country's team to just compete for the other country, particularly small ones.)
I suppose one could just allow a bi-national team like this one to compete. I mean they give 2 gold medals to the winning team, what harm is there if it's one for each country? Seems like something grand in the spirit of international cooperation. The problem is the rules about how many competitors a country can send. Both nations might be afraid to send half of a team if it counted the same as sending the full team against their quota. If it only counted half, they would need to send half of two teams, but it might work.
The national borders are becoming less important in the big money sports. The US-Canadian ice dancers train in the US. I recall at least one eastern team which trained in Calgary. (Such training in richer countries is common.) Why not present the world with the best team?
