A Beginner’s Guide
The World Feed (or to give it it’s actual name: the “International Feed”) is the primary channel that contains the bulk of F1’s TV coverage during official sessions, and is the feed that all the broadcasters will be commentating on while the session is in progress. If you’re watching a Grand Prix on TV or online, you’re almost certainly watching the World Feed. You can usually tell you’re watching the world feed (as opposed to a broadcaster’s own footage) by the presence of the F1 logo in the bottom-left of the screen.
The World Feed (in fact, any feed) is not a TV channel in the conventional sense of the word – it’s simply a continuous stream of live footage that all broadcasters will show during the race in order to show the live track action to their viewers (rather than each broadcaster filming the event separately, which would naturally be a logistical nightmare if each of them having their own crew & equipment at every corner).
The World feed is active throughout almost the entire day of the Grand Prix weekend, and also covers F1’s support sessions/track parades etc. that run in between the F1 action, for the benefit of track-side screens as well as broadcasters who are also covering the support races.
FOM do not provide their own “in-house” commentary team for F1 sessions on the World Feed – this is left to the individual broadcasters. However, FOM does provide its own English-language commentary for F2, F3 & Porsche Supercup sessions.
Individual broadcasters often “augment” the World Feed in various ways while the session is in progress – maybe by inserting their own short replays if they have missed action due to taking a commercial break, or by cutting away to a live or pre-recorded in-vision interview or live piece of analysis (something that Sky in the UK do, with frequent pit-lane during practice sessions). Often broadcasters will use a Picture-in-Picture window to show the relevant cutaway. Typically broadcasters are only allowed to do this during practice sessions and during the breaks in qualifying, as it is forbidden during the race and when the qualifying sessions are in progress.
