ETSI Satewwite Digitaw Radio - Wikipedia
ETSI Satewwite Digitaw Radio (SDR or ETSI SDR) describes a standard of satewwite digitaw radio. It is an activity of de European standardisation organisation ETSI.
It addresses systems where a satewwite broadcast directwy to mobiwe and handhewd receivers in L band or S band and is compwemented by terrestriaw transmitters. The broadcast content consists of muwticast audio (digitaw radio), video (mobiwe TV) and data (program guide, text and graphicaw information, as weww as off-wine content). The satewwite component awwows geographicaw coverage at wow cost, whereas de terrestriaw component improves reception qwawity in buiwt up areas. The specifications considers conditionaw access and Digitaw Rights Management.[1]
1worwdspace wiww use ETSI SDR in its new network covering Europe from 2009.[2] Awso Ondas Media has announced to use ETSI SDR.[3]
The ETSI SDR is awso simiwar to de Sirius XM Radio, de S-DMB used in Souf Korea for muwtimedia broadcasting since May 2005, de China Muwtimedia Mobiwe Broadcasting (CMMB) and de defunct MobaHo! service (2004-2009). The DVB-SH specifications, which de DVB Project has created, target simiwar broadcast systems as ETSI SDR.
1 ETSI SDR Standard
ETSI SDR Standard[edit]
The ETSI SDR standard awwows impwementation of parts of such networks in an interoperabwe way. So far, ETSI has standardized de physicaw wayer of de air interface (radio interface). This awwows impwementation of demoduwators in integrated circuits. The physicaw wayer is described by de fowwowing parts of ETSI EN 302 550:
ETSI EN 302 550-1-1 "Satewwite Earf Stations and Systems (SES); Satewwite Digitaw Radio (SDR) Systems; Part 1: Physicaw Layer of de Radio Interface; Sub-Part 1: Outer Physicaw Layer"
ETSI EN 302 550-1-2 "Satewwite Earf Stations and Systems (SES); Satewwite Digitaw Radio (SDR) Systems; Part 1: Physicaw Layer of de Radio Interface; Sub-Part 2: Inner Physicaw Layer Singwe Carrier Moduwation"
ETSI EN 302 550-1-3 "Satewwite Earf Stations and Systems (SES); Satewwite Digitaw Radio (SDR) Systems; Inner Physicaw Layer of de Radio Interface; Part 1: Physicaw Layer of de Radio Interface; Sub-Part 3: Inner Physicaw Layer Muwti Carrier Moduwation"
These dree parts repwace de previous ETSI SDR standards ETSI TS 102 550, ETSI TS 102 551-1 and ETSI TS 102 551-2.
The fowwowing technicaw report contains guidewines for de use of dese standards:
ETSI TR 102 604 Satewwite Earf Stations and Systems (SES); Satewwite Digitaw Radio (SDR) Systems; Guidewines for de use of de physicaw wayer standards
The fowwowing technicaw report describes de facts and assumptions on which de SDR standards are based:
ETSI TR 102 525 "Satewwite Earf Stations and Systems (SES); Satewwite Digitaw Radio (SDR) service; Functionawities, architecture and technowogies"
Note dat in dis document de word "may" repwaces de word "shaww" due to a decision of de ETSI Board in June 2006.
Aww ETSI specifications are open standards avaiwabwe at ETSI Pubwications Downwoad Area (dis wiww open ETSI document search engine; free registration is reqwired to downwoad PDF fiwes).
