Digital Satellite Television (also known as DStv) is MultiChoice's multi-channel digital satellite TV service in Africa, launched in 1995. Subscribers in South Africa also receive SABC 1, 2 and 3 and the privately owned free-to-air terrestrial channel E.tv. These are not available to subscribers elsewhere.

DStv has numerous products and services, in 2005 introduced its own Personal Video Recorder (PVR). On 24 July 2008 they introduced the High Definition Personal Video Recorder (HD PVR) which allows the subscriber to record DStv's content.
