SCPC (Single Channel Per Carrier)
SCPC stands for Single Channel Per Carrier.
SCPC is a form of satellite transmission where each channel is transmitted on a dedicated single carrier.
The alternative to SCPC is MCPC (Multiple Channel Per Carrier).
MCPC is more efficient than SCPC, but SCPC is still utilized for some satellite feeds. By using SCPC, satellite users are able to uplink to the same transponder from multiple locations.

- MCPC (Multiple Channel Per Carrier)
MCPC stands for Multiple Channel Per Carrier. MCPC is a form of satellite transmission where each carrier is utilized to transmit multiple channels. MCPC transmits multiple video or audio channels on one carrier by utilizing Time Division Multiplexing (TDM). The alternative to MCPC is SCPC (Single Channel Per Carrier). MCPC is used much more than [...]...
- SSB (Single Side Band)
SSB stands for Single Side Band. In SSB, the carrier and one of the side bands are eliminated before transmission. This enables the power amplifier to focus all transmitter energy on the single remaining sideband. SSB allows greater range with less power consumption. SSB also enables more efficient utilization of the radio frequency spectrum. The [...]...
- 5.1 Channel Speakers
Systems that use 5.1 channel speakers are used for surround sound applications and have been steadily growing in popularity throughout the audio industry for use in theaters and residences alike. 5.1 channel speakers produce sound that can be heard from all directions around a listener, simulating the effects of real sounds. 5.1 channel speakers are [...]...
- Uplink
Uplink refers to a transmission of data in which data flows from a ground-based transmitter to an orbital satellite receiver. Uplink is used to send data to a satellite in Earth’s orbit in order to make changes to the way the satellite functions or simply redirect data to another ground-based receiver. Uplink is used in [...]...
- Fibre Channel
Fibre Channel is a set of standards for connecting storage devices in a fabric network. The Fibre Channel standard identifies a protocol and a collection of physical interfaces for managing computer peripheral components. This standard’s key purpose is managing large numbers of storage devices. Fibre Channel uses serial interfaces working at symbol rates from 133MB/s [...]...
I have one simple query regarding SCPC and that is whether we use one carrier for single video, audio and data channel or separate carrier for video , separate for audio and separate for data.
