What does Simulcast mean?
A simulcast presents the same programme at the same scheduled time through more than one channel or distribution route. Different delivery routes can still introduce different amounts of playback delay.
Why it matters
Television, radio and internet coverage sometimes share a production. Simulcast describes that simultaneous intention; it does not mean every screen receives each frame at precisely the same instant. Encoding, distribution and player buffering can put one route behind another. A second transmission may also include its own surrounding presentation or accessibility options. If your household uses two routes for the same event, audible differences between rooms are often a timing issue rather than different action. Lower the sound on one screen before trying to compare them.
A practical example
A broadcaster may show a debate on its television channel and stream that transmission through its own website. A web viewer hearing a reaction later than a television viewer can still be watching the simulcast.
