The satellite transponder capacity, as well as the national operating system equipment located in Washington, DC, is a component of the Public Radio Satellite System (PRSS) The PRSS includes more than 400 downlinks, and provides service to more than 200 program producers and distributors.
Many additional stations also receive programming sent over the satellite through local connections with downlink stations or through the ContentDepot portal. Located at NPR headquarters in Washington, DC, the Network Operations Center (NOC) is our state of-the-art system control and routing center for audio and data transmissions as well as the master uplink for PRSS programming.
Multiple Channels Per Carrier (MCPC) is a delivery technology that places multiple channels on a single satellite carrier. Clients who have MCPC networks can specify the bandwidth they need, providing more flexibility for their programs and channels. Stations and networks that use MCPC also save money by using just one carrier rather than multiple receivers.
MCPC can enhance your network through the use of "store/forward" technology. "Store/forward" technology saves audio, video, or data files at the centralized uplink until they are needed for use at a later time. Stored files are then automatically forwarded to the appropriate broadcasting location (or MCPC receiver).
