frequency of TV handheld cameras

[alok]

not radio engineering related, TV engineering instead . . . but maybe somebody has the answer,

When watching a sporting event and I see a hand-held camera, without a cable . . . what frequency do these cameras transmit their pictures on?
How is the frequency shared with other handheld cameras at the event?
Also, any communications between camera op & control room ( or truck ), is that on a separate frequency or does it ride on the same frequency the video is on?

Usually in the 2.4 or 5.8Ghz bands. Digital spread spectrum.

How is the frequency shared with other handheld cameras at the event?

Each camera/base has a unique watermark or IP address. There is usually a frequency coordinator or group assigned to the venue who coordinates band/frequency use for all RF devices around and during the game.

Also, any communications between camera op & control room ( or truck ), is that on a separate frequency or does it ride on the same frequency the video is on?

Depends. Some use the intercom embedded in the digital video/audio stream for PL with the photographer, but the talent uses a separate digital wireless mic and IFB.
