.... yeah ya do. not hard to follow Mr. Farkas.... However..... @Fenway ?..... maybe you could expound upon how the live feed from a game goes from mobile to the station & network, and how from there at the time the game filmed on 16mm off a monitor & then distributed to the various stations that you listed in a post above which also features the old Kinescope. Uh?
Up until 1980 or so, feeds from the venue were using leased telco lines and to get a signal into or out of Canada a broadcaster had to use CN in Toronto and in the late 70's the CN Tower was built. Then stations started to use satellite delivery and later fiber optics but regulators in Canada made sure the CN Tower would not become a white elephant.
Stations buy blocks of time (by the hour ) and if a game is running late you have to call CN in Toronto to keep the line open but they are notorious for not answering the phone. As I showed above CBC lost the signal from LA while the Stanley Cup was being presented and CBC in desperation took Channel 2 in Buffalo off the air so viewers in Canada could see it.
Kinescopes like the one in this thread were far from perfect but luckily for us they exist.
