multiple channels per carrier (MCPC)

An average satellite transponder has a bandwidth of 27 MHz. Typically, the highest symbol rate that can be used in SR 26 MS/s, and multiple video or audio channels can be transmitted simultaneously. MCPC uses a technique called Time Division Multiplex to transmit multiple programs, which works by sending data for one channel at a certain time and then data for another channel at another time. Many encoder manufacturers are currently experimenting with statistical multiplexing of MPEG-2 data. Using this technique, channels that need high data rate bursts in order to prevent pixelization of the picture, such as live sports events will obtain the bandwidth as they need it by reducing the data rate for other services that do not. Statistical multiplexing should improve perceived picture quality, especially on video that changes rapidly.

It also has the advantage of requiring no changes in the receiver equipment.
