Joint Master Control (JMC) —

Refers to the organizations providing centralized master control and other value added services to the PTV stations that they serve.  These may be organized by stations, or may be independent commercial provided services. 

There are two JMC architecture models: centralized playout and de-centralized playout models. Each model is comprised of station “spokes” around a central master control “hub.” 

The centralized playout model involves the station “spokes” receiving a media playback stream from the master control “hub.” Station “spokes” ingest locally produced media and send it to the “hub” for storage. The “hub” also receives all RT and NRT content and stores it locally for future playout. Messaging between the hub and spokes includes schedule and program metadata synchronization.

In the de-centralized playout model, the “hub” still receives all RT and NRT content; however, this content is not stored locally but rather in a centralized cloud archive from which it is pulled by station “spokes” based on their content schedules. Also in this model, automation and playout servers are on the station side rather than the hub side, as in the centralized playout model. Messaging between the hub and spokes includes media availability updates and technical metadata synchronization.

 

LAN (Local Area Network) —
