ETSI Satellite Digital Radio (SDR or ETSI SDR) describes a standard of satellite digital radio. It is an activity of the European standardisation organisation ETSI.
It addresses systems where a satellite broadcast directly to mobile and handheld receivers in L band or S band and is complemented by terrestrial transmitters. The broadcast content consists of multicast audio (digital radio), video (mobile TV) and data (program guide, text and graphical information, as well as off-line content). The satellite component allows geographical coverage at low cost, whereas the terrestrial component improves reception quality in built up areas. The specifications considers conditional access and Digital Rights Management.[1]
1worldspace planned to use ETSI SDR in its new network covering Europe from 2009, but the company went defunct before it launched its service.[2] Also Ondas Media has announced to use ETSI SDR.[3]
The ETSI SDR is also similar to the Sirius XM Radio, the S-DMB used in South Korea for multimedia broadcasting since May 2005, the China Multimedia Mobile Broadcasting (CMMB) and the defunct MobaHo! service (2004-2009). The DVB-SH specifications, which the DVB Project has created, target similar broadcast systems as ETSI SDR.
