The Broadcast Tower
A scheduled premiere simulated from a recorded upload: the playlist reveals only what has aired, late viewers land at the live edge, and nobody can skip ahead until it ends.

The whole recording is on the CDN, so you can replay anything up to the live edge.
Blocked while the premiere is live: segments past the live edge have not aired. Allowed once it ends and the post is on-demand.
A scheduled premiere waits, built from a recording. Choose when you join and how you try to move through it.
The premiere is a recorded upload, already transcoded and sitting on the CDN. No live encoder runs; the whole film is ready before anyone arrives.
The clock reaches the scheduled time. From here the playlist reveals only the segments whose running time fits inside now minus the start.
The gate opens a segment at a time as broadcast time passes, up to segment 6.
Several segments have already aired. You do not start from the beginning: you land at the live edge, where everyone watching now is.
You step back through the segments that have already aired. The whole recording sits on the CDN, so everything up to the live edge is yours to replay.
You watch a scheduled premiere built from a recording. The live edge is at segment 6 of 8: everything before it can be replayed, nothing after it exists yet.
A model of the design, not a shipped feature. It shows how a scheduled premiere would behave if it were simulated from a recording, reusing the upload, transcoding and CDN path rather than running live encoders.
The premiere is a recorded upload. It is already transcoded and sitting on the CDN before anyone arrives, so no live encoder runs. The clock dial is the broadcast: its needle is the playhead. As time passes the gate opens one segment at a time, revealing only the segments whose running time fits inside now minus the scheduled start. Segments that have aired stand raised; the rest wait under the shutter.
When you join, you land at the live edge, not at the beginning. Because the whole recording is already on the CDN, you can rewind through everything that has aired. You cannot skip past the live edge, though: those segments do not exist in the playlist yet. Once the premiere ends, it becomes an ordinary on-demand post and you can move anywhere.
This is a model of the design, not a shipped feature. It shows how a live-feeling premiere behaves when it reuses the upload, transcoding and CDN path that already exists.
