A playlist is the first thing every new channel builds and the first thing it outgrows. Files play in order, each starting when the last one ends, and by Thursday the 9pm film starts at 9:07 because Tuesday’s episode ran long. A schedule is anchored to the clock: the film starts at 9:00 whatever came before, the item before it is trimmed or padded to fit, and the guide can promise a time because the grid keeps it. That is the difference viewers notice and listings partners require.
Where scheduling gets hard
Week one is easy. Month three is where a 24/7 channel is hardest to run by hand: 730 hours to fill, series that must not repeat within a day, a library that has grown past what anyone remembers, and the Saturday match that moves every week. The scheduler’s job is to make those rules once and enforce them: recurring blocks so the strip is built once, series order so the episode count is kept for you, repeat spacing so the same film is not on twice on Sunday, and auto-fill so a gap is filled from the library under those same rules rather than by whatever was nearest. On the FAST plan and up, AI scheduling takes the rules and drafts the weeks, and the draft is an ordinary grid you correct.
The plan is also the guide, the breaks and the record
The same grid publishes the programme guide in XMLTV, JSON and a web page, carries the SCTE-35 ad breaks each airing signals, and writes the as-run log playout keeps for a year. Nothing is exported by hand and nothing is kept in a second system, which is what makes a schedule change on Tuesday true everywhere on Tuesday. Live slots sit in the same grid: the contribution feed arrives over RTMP, SRT or RIST, the block switches on time and hands back on time, and a dropped feed falls back to the schedule.
The cost
Scheduling is part of the channel, not a licence beside it. Every channel plan, from $254 per month, includes the grid, the guide, the graphics and unlimited delivery; AI scheduling is on the FAST plan and up. The playout software guide covers what to check in any scheduler, installed or cloud.
