Pure-file playout — passthrough or ABR ladder
A 24/7 file channel — no live sources. The operator schedules items from a media library onto the playlist, and the programme ships one of two ways: in passthrough, the source’s coded frames untouched, or re-encoded into the default ABR ladder for adaptive delivery. The same channel one encode switch apart — the repo carries both configs (file-passthrough, file-ladder).
01 A scheduled playlist
Section titled “01 A scheduled playlist”File items scheduled as a running channel, each with its title, duration and state, and a live playhead on the on-air item.
02 What aired
Section titled “02 What aired”The as-run record of the file channel — each item logged as it aired, gap-fill covering any hole.
03 Or re-encoded to a ladder
Section titled “03 Or re-encoded to a ladder”The ladder variant: the file programme re-encoded into the CMAF ABR ladder for adaptive delivery.
