I'm also asking what could be a "fast feed" when a competition is live broadcast on many TV channels around the world with less than one second delay.
The delay is bigger than what you think. You can check that yourself if you know someone who lives next to a stadium and if a game is televised live. If you sit in the apartment and you hear the cheers from the fans after their team scores, pay attention to how long it takes for the goal to be seen on TV. Analog transmission is the fastest. Cable and satellite depends on the TV station. And then you have to consider SD and HD channels. SD are faster most of the time, but not always.
Even if the game is televised on multiple channels, each one of them have different delays. You usually wouldn't notice it unless you have access to multiple sports packages and transmission sources such as cable and satellite. Not to mention IPTV that can be 40-50 seconds behind and even more if you are getting it from the worst kind of service providers.
