What does Live edge mean?

The live edge is the most recent part of a live presentation available to the player. It is not necessarily the real-world event occurring at that exact instant. Production, encoding and distribution have already introduced some delay before media becomes playable.

Why it matters

Players commonly remain behind the edge to keep a safety cushion. Moving closer can reduce viewing delay while leaving less tolerance for late delivery. A paused or replayed session may be much farther back without any network fault. Use the player's supported live control to return rather than assuming a router restart removes all delay.

A practical example

Two screens may begin at different positions and remain several seconds apart. Reopening one session can change its position without changing the underlying broadband connection.
