Centralcasting (Centralcasting Hub) – Centralcasting centrally locates broadcast operations for distribution to multiple points. Centralcasting can result in operational efficiency and cost savings.

If a regional or national broadcaster is providing locally based transmission to multiple population centers such as towns and cities, that likely is the opposite of Centralcasting. If the content instead is distributed to these areas, with each having its own master control and the ability to do local production insertions, that's more likely to be Centralcasting.

Benefits of Centralizing a broadcaster's operation often include the need for only minor personnel additions as well as the increase in channel capacity.
When centralizing a facility it's important to make it scalable.
