I just realized today that Google Fiber has the option to change the resolution to 1080p24. This is awesome but at what frame rate are cable shows recorded and broadcasted in?
Scripted drama, sitcoms and some documentaries are usually shot in 1080/24p. Sport, entertainment, news, daytime soap and some documentaries are often shot at 720/60p or 1080/60i in the US. (1080/60p is close to unheard of as a production format)
Linear HD networks (i.e. channels or stations that you watch live) run at either 720/60p or 1080/60i - with 24p content either played out or delivered mastered - with 3:2 pull-down. If a show was mastered and delivered in 1080/24p, then if it is made available on a VOD platform, it will be often be 24p. If a show was delivered 720/60p or 1080/60i native then it is likely to be made available on VOD services at 30p (not many VOD services run at full 60Hz motion yet AIUI)
