This page tells the **ops-side story** of a 2110 facility as it flows left→right: Ingest, Store, Produce, Playout/Tx/Streaming—what each team does, key handoffs, and what “good” looks like.
PTP domain stable
IGMPv3 (S,G) joins predictable
2022-7 hitless end-to-end
DSCP preserved
Zero queue drops
Ingest / Acquisition
Senders publish 2110-20/30/40 (often dual 2022-7 A/B), PTP-locked, with SDP + IS-04 registration.
Ops: Studio/Field + Network/Timing
- Controls: Router UI or IS-05 connects receivers; IGMPv3 edge joins materialize.
- Good: Stable PTP offset, clean RTP (no gaps), correct DSCP (PTP=CS6, media high), both A/B legs healthy.
- Stumbles: Wrong VLAN/MTU, lapsed API certs, mixed PTP domains, snooping off, QoS mis-marking.
Store / Archive
Recorders/services subscribe to flows, generate mezz/proxy, push to NAS/Object with checksums & lifecycle.
Ops: Media Ops + Storage
- Controls: MAM/orchestration; NMOS or vendor APIs for subscriptions.
- Good: Lossless capture, fixity verified, proxies on-time, archive tiering working.
- Stumbles: Under-provisioned IOPS, UTC skew on stamps, multicast crossing L3 without PIM-SSM.
Process / Production
Switchers, graphics, audio, multiviewers, replay consume many flows and emit new ones in real time.
Ops: PCR/Studio + Network
- Controls: IS-04/05 directory + panels; IS-07/08/09/10/11 where needed.
- Good: Frame-accurate switching (PTP tight), deterministic latency, no buffer underruns, hitless A/B on MVs.
- Stumbles: Residence-delay spikes, lack of 2110-21 pacing, ECMP hashing co-locating A/B legs.
Playout / Tx / Streaming
Playout & encoders subscribe to final program; gateways emit SDI if needed or IP to contrib/CDN.
Ops: MCR/Tx
- Controls: Router automation; SCTE via 2110-40; IS-05 salvos for primary/backup chains.
- Good: End-to-end hitless, encoder ladders stable, SCTE timing aligned, clean prim/backup failover.
- Stumbles: Excess A/B differential delay, DSCP remark in DMZ, MACsec MTU overhead unaccounted.
