How do they film the Olympics?

[NowhereMan 1966]

I was watching the men's half-pipe snowboarding event yesterday and I noticed the picture wasn't too great, it was kind of dazzling bright, sort of like the gamma was turned up too high or something. I'm watching the women's half-pipe now and the picture seems OK tonite. How do they film the Olympics, do they use digital cameras, then convert it to analogue? Do they use PAL/SECAM cameras and then convert it to NTSC? I do remember the Albertville games in 1992 when I watched the hockey games then and I noticed a lot of the same thing plus there were times it seemed like it skipped a frame then Back in 1992 and now, the TV I'm using is my infamous 1982 Zenith 25" System 3 console
