The cable side is a transport question. The channel emits a constant-bitrate SRT or RIST stream, on the FAST plan and up, and the headend takes it either directly, if the IPTV middleware or encoder farm accepts an SRT input, or through a small decoder that turns it into SDI or an MPEG transport stream for the modulator. Your headend engineer will know which in one conversation. It is the same output the satellite migration uses to keep an uplink fed, and it runs beside the streaming outputs, not instead of them, so the old playout box can stay connected while you compare.
The meeting
A live slot in the grid takes a feed over RTMP, SRT or RIST from the chamber, the gym or a phone, switches to it at the scheduled time, and returns to the schedule when it ends. Meetings run long, so the slot can be held open under manual control. If the encoder in the chamber drops, playout falls back to the schedule, or to a backup input and then a standby screen on the FAST plan, and returns on its own. The guests and call-ins page covers bringing a remote speaker into the broadcast from a browser link.
Why stream as well as feed the cable
The cable system reaches the households that still subscribe. The web player, casting and the published programme guide reach everyone else: the family that cut the cord, the student away at college, the resident watching the planning meeting on a phone at work. Analytics count them at the edge, city by city, which is the number a council asks for at budget time and a sponsor asks for at renewal. Delivery is unlimited on every plan, so the night the whole town watches the vote costs what a quiet Tuesday does.
The money
The plan is flat, from $254 per channel per month, and the headend output needs the FAST plan. Server-side ad insertion is on every plan: local sponsors go into the marked breaks, the report shows them what ran, and serving on the streamed channel is $1 per 1,000 delivery-confirmed impressions. The TV channel cost page puts the whole bill beside a playout server, a rack and a maintenance contract.
