Presentation on satellite radio

  1. 1.  DEFINATION HISTORY SYSTEM DESIGN WORKING RADIO Vs SATELLITE RADIO MARKET PLAYERS PROS AND CONS CONCLUSION
  2. 2. Satellite radio is ananalogue or digital radiosignal that is relayedthrough one or moresatellite and thus can bereceived in a much widergeographical area thanterrestrial FM radiostations .
  3. 3.  World space corporation was founded in 1990 by NOAH. A. SAMARA, chairman and ceo. He founded the company with a vision to provide digital satellite audio, data, and multimedia services primarily to the emerging market of africa and asia. To implement this vision , world space conceived and built the first ever satellite radio infrastructure in the world. In the last 12 years the company has built the satellite and launched two companies to provide audio, data and multimedia broadcasting coverage to africa and asia.
  4. 4.  Satellite radio uses the 2.3 GHz S band in North America and generally shares the 1.4 GHz L band with local Digital Audio Broadcasting stations. Two or three are usually sufficient to provide coverage for an entire continent. Local repeaters enable signals to be available even if the view of the satellite is blocked. Major tunnels can also have repeaters.Each receiver has an Electronic serial Number(ESN) Radio ID ,to identify it.Satellite radio also transmits program- associated data,with the artist and title of each song and possibly the name of the channel.
  5. 5. UPLINK STATION, SATELLITE TERRESTRIAL & REPEATERS TERRESTRIA L REPEATERS CONTROL ROOMFIXED RECEIVERS MOBILE RECEIVERS
  6. 6.  A single song , as it travels off a CD ROM or Hard disk gets diced and sliced in an encoder. Combined in a multiplexer. Gets bounced up onto the satellite. Then back down to the receivers where it is decoded with header information. Finally transforms into analog so that the primitive human ears can enjoy it.
  7. 7.  Analog Radio Here the audio signal is piggybacked on a carrier signal by means of analog modulation techniques like AM,FM. Digital Radio Here , the audio signal is digitized and then transmitted using digital modulation techniques like QAM. AM SATELLITE RADIO FM HD RADIO
  8. 8. ANALOG VS DIGITAL RADIO ANALOG DIGITALCompression Not Possible PossibleBandwidth Usage Large(not efficient);FM- Low 200KHz%/channelLink Adaptation Not possible PossibleMetadata Not Available AvailableEncryption Not Possible PossibleInterference Highly Susceptible Less Susceptible
  9. 9.  COST : AM and FM(terrestrial) radio are both free of charge,so long as you have a radio. You simply turn the radio on and tune it. Satellite radio,on the other hand, requires a monthly subscription fee that varies ,depending on which service you choose and how many stations you want to service. This cost difference is probably the highest advantage teresstrial radio has over satellite radio. PROGRAMMING: The biggest advantage satellite radio has is the context of its content. When you simply turn on your am/fm stereo,your entertainment options are restricted to the stations you can receive. With fewer choices,you may be stuck with an insufficient number of options. Satellite radio ,on the other hand ,features more than 200 channels that are narrowly foccused to all kinds of interests.
  10. 10.  Reception : Depending on your location , you may only able toreceive a couple dozen station when listening toterrestrial radio. Sattelite radio delivers good reception. Portability :At the moment, AM & FM radio have a big advantageover sattelite radio. It is very easy to switch on yourportable radio and listen to some tunes or a talk show.Reception of sattelite radio require a much morecomplicated antenna ,so portable sattelite radio unitcost is far more than portable terrestrial radio.

  12. 12. SIRIUS VSXM Satellites SIRIUS 3 satellites XM 2 satellites Price $12.95 per month $12.95 per month for basic package Availability The continental United The continental United States and Canada States and Canada Subscribers 8+ million in 2008 9+ million in 2008Already Installed Available installed in Available installed in a many cars, including variety of cars, including Chrysler, BMW, Mazda, Audi, GM, Honda, Nissan, Mitsubishi, Toyota, Hyundai, Toyota and Volkswagen and Ford cars Porsche models Programming 130+ channels, 170+ channels, including:69 commercial- including:70 commercial- free music channels18 free music channels92 news and talk channels news, sports, talk and entertainment channels
  13. 13.  One of the greatest advantage of satellite radio is the fact that the programs are not interrupted by commercials. Another great thing about satellite radio is the absence of static. Satellite radio tuners receive,along with the actual radio programs,an influx of metadata that consists of information regarding song title,artist,radio program and radio channel. All satellite radio programs are uncensored.
  14. 14.  Subscription fee Receiver purchase Signal interruptions Signal Limitations Mature Content
  15. 15. Radio Listenership Is Growing240,000,000 235 Million Listeners230,000,000 Radio’s total220,000,000 audience has grown 16%210,000,000 since 1994200,000,000 __________ Radio has190,000,000 added six million listeners180,000,000 since 2005 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 Source: RADAR, Fall Survey Reports, Copyright Arbitron (Monday-Sunday, 24 Hours, based on Weekly Cume, 12+
  16. 16. Radio Reaches 92 million More People Each Week Than Google Reaches In An Entire Month Sources: Radar 97, June 2008 (Monday-Sunday, 24hrs, based on daily cume 18+) ; ComScore May 2008
  17. 17.  Planning to have Satellite radios as an option in upcoming cars. Channel line-up improves overtime. Keeping one eye on road and listening to radio traffic report. Soon Satellite radio system in cars may able to match it. Down the road,having video streaming through your satellite radio system is a possibility.
  18. 18. You’ll fall in love with the way Radio is emerging now a days in terms of music , entertainment and knowledge.The time is here when Radio has become an integral part of our lives and there is no bad in enhancing the techniques , to get the facilities which we need to enjoy and learn something new.
