| digital compression |
The reduction of the data needed to be broadcast (video, audio or data) giving minimum loss of received quality so as to make maximum use of the available transmission capacity. Thus, several digitally compressed TV channels can be transmitted in the space required for a single uncompressed analogue TV channel. The main way that compression works is by eliminating some of the redundant data in the signal.

| digital compression |
A process of translating video images into a digital code which takes up less transmission space than the original signal would have. This allows more channels per satellite transponder: from four-to-one for live video to eight-to-one for film.

Digital compression uses the same principals as Digital Audio Broadcasting. The video signal is compressed into MPEG format, where it takes up less space. It is then beamed to a dish where it is the receivers job to decode it. This is same technology used for DVD. The compression allows for a smaller dish size and is the reason that DBS is replacing the larger satellite dishes.
