Satellite radio systems are actually part of a larger group of broadcasting mediums, which specialists refer to as Digital Multimedia Broadcasting or DMB. This digital transmission system is used in order to send data to different receivers such as radios, television sets or mobile phones and PDAs. There are two different ways of using digital multimedia broadcasting – S-DMB which is broadcasting via a satellite or T-DMB which uses terrestrial emitters. The complexity of the entire digital multimedia broadcasting field is huge. Out of all the features and characteristics digital broadcasting offers, satellite radio is probably the most spectacular as it generated immense interest and triggered an intense competition between the two main satellite radio broadcasters, Sirius and XM Radio. The development of satellite radio and other forms of digital broadcasting is spectacular because it offers two main qualities that terrestrial emitters are deficient in: quality and coverage. In the case of satellite radio, for example, the sound quality from a satellite broadcast is much higher than AM or FM broadcasts, as the hissing noises and transmission disturbances are eliminated.

Technical features of digital multimedia broadcasting – overview

Whether it refers to television, satellite radio or cell phone transmissions, digital multimedia broadcasting is based on the Eureka 147 DAB standard. Digital television uses the T-DMB which is made for transmissions on frequency bands III (VHF) and L (SHF). T-DMB is an ETSI standard (TS 102 427 and TS 102 428).
T-DMB uses MPEG-4 Part 10 (H264) for the video and MPEG-4 Part 3 BSAC or HE-AAC V2 for the audio. When it comes to satellite radio, there were a few issues to be resolved by the main satellite radio broadcasters. The satellite radio receiver needs to be in the line of sight of the satellite to receive the transmission ? and there is the problem of having different landscaping objects block the direct transmission. Land based devices were installed in order to eliminate the lack of direct satellite transmission. Since the wider spectrum of broadcasts has to be covered, digital multimedia broadcasting uses OFDM-4DPSK modulation and a chip of T-DMB receiver is also provided by MPEG-2 Transport Stream De-multiplexer. This helps reduce the negative effects of shadowing and fading, present in many digital transmissions.

The future of digital multimedia broadcasting

The transfer from the analog world to the digital one is obvious in all fields of work. Since digital multimedia broadcasting is developing so quickly, there is a silent battle going on between the new age digital technology and the classic analog one. OF course, many compare the transition from the analog to the completely digital era with the way audio cassettes were replaced by CDs and later on even DVDs. However, the development of digital multimedia broadcasting is slower since it happens on so many levels at the same time. Digital television is taking us into new spaces that are basically hybrids of the features of regular TV and characteristics of the Internet. Satellite radio is also taking huge leaps forward, with more and more programs having satellite radio exclusivity. There are even discussion of moving events like the MLB exclusively on satellite radio, which would provide one of the first deadly strikes against terrestrial radio broadcasting. Digital data transmission is fast and accurate, and so far reality proves that the satellites used in order to facilitate broadcasting and reliable. Most digital multimedia broadcasting companies that own satellites also have backup ones ready to go in orbit and replace a defective one. Some other benefits of digital multimedia broadcasting recommend it as a next step in the development of broadcasting. From the consumer?s point of view, the quality and interactivity options of digital TV or satellite radio broadcasts are important features. Although most digital multimedia broadcasting channels and technologies are still complex and sometimes expensive, the evolution of digital broadcasting seems to be here to stay.

Everybody has heard about satellites. But how many people heard about satellite radios? Satellite radio is a subscription radio service. It?s somehow identical to cable television, with the difference that it provides a wider range of stations not available on a standard AM / FM radio. There are many questions to be answered about satellite radios like ?How does satellite radios work??, ?What kind of equipment should I purchase?? etc. but in this article I will try to answer a question that first pops up in everybody?s mind: ?HOW MUCH DOES SATELLITE RADIO COST?? This is a tricky question because the cost of a satellite radio is divided in two: installation (or activation) costs and the monthly subscription fee.

Activation costs

Activation costs refers to the amount of money that are to be spent on a XM or Sirius Satellite Radio to start the service. Although you can find many promotions that allows you to save up money, the activation costs vary, being able to make the activation by phone or by World Wide Web. To be more precise, if you activate your satellite by phone, you will pay $15.00 if you choose Sirius Satellite or $14.99 by choosing XM and, as for WWW activation, the cost of goods is somehow lower: $5 with Sirius or $9.99 with XM. As for the monthly subscription costs we will discuss this below, but, before that, I must say that recent media campaigns are dramatically dropping the prices for installation and activation, both on Sirius or XM, in some cases even offering free activation.

Typical costs for a car dedicated installation

If you want to install a satellite radio into your car you are to consider buying a new satellite-ready car stereo if you don?t have one. Although many local dealers offer built-in car satellite radio, there is still the problem of having a satellite radio receiver. And these, as you may notice, cost money. It is possible though to use the existing car stereo that does not support satellite radio. How? There are two known ways of connecting the receiver to the available non-satellite radio car stereo. First, by using the radio inputs (usually the CD) and installing a control unit for tuning up the satellite radio streams. The second method consists in installing a satellite radio receiver, which broadcasts the satellite radio signal on a FM frequency. The place where you can install the receiver depends: under the seat, in your trunk, etc. taking care of connecting the receiver to the satellite radio antenna mounted on the car?s exterior.
So, there will be a minimum cost of $350.00 and a maximum of $600, like below:

Receiver $75 – $125
Radio $125 – $250
Antenna $60.00
Labor $80.00
Activation $10

Costs for a dedicated home installation

If you choose this option, that means you will have to install a dedicated stereo receiver unit, which in some cases is similar to regular AM / FM receivers. As an additional cost, you will have to buy an antenna, which can be found at a price of $60. Here is a short review of the approximate price of installing a dedicated stereo receiver unit:

Receiver $150 – $300
Antenna $60
Activation $10

Costs for a Portable Unit

Portable units gives you the ease of using you brand new satellite radio wherever you want, but, in every room you will have to own a home kit (antennas, output cables and power supplies). The price for this option is around $400.

Receiver $120
Home kit $140
Boombox x2 $100
Activation $10

Subscription costs

As for the subscription costs, it depends if you own a Sirius or XM Satellite Radio.
Subscription costs for a Sirius Satellite Radio are paid monthly where the charge is $12.95, with a low adjustment is you subscribe to a year or two. The highest number of Sirius radios that can be activated are three for $6.99 each per month. Business subscriptions are $24.99 per month. Another interesting thing is that for $499.99, Sirius is offering a life time subscription.
On the other hand, if you have a XM Satellite Radio, you will have to pay a monthly charge of $9.99. Still, some channels are to be paid separately, like Playboy Radio, which costs an additional $2.99 per month. Commercial and Business Subscriptions cost $24.99 per month.

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the provider?s income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.
Another great thing about satellite radio is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The satellite radio signal is digital, which means that you will get crystal-clear sound wherever you go.

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. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receiver?s display.
All satellite radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying ?beep? sounds.
Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to satellite radio online on your computer.

If you still are not convinced on why you should pay money for something that you can get for free, think about how much time you have wasted listening to commercials and all kinds of other boring stuff on terrestrial radio programs. Traditional radio is not free, despite the popular belief. It is time-consuming and irritating because you have to listen to five minutes or more of commercials so that you can finally hear a song you like. The satellite radio subscriptions are very affordable and, for around 13 dollars per month, you get exactly the programs you want, which you can listen to wherever you are, at the best sound quality.

Satellite radio is great for you especially if you travel a lot. If you are traveling across the United States of America, for example, you can listen to the channel or channels you want during your whole trip, without losing signal or getting static. If you have a traditional radio, you will have to keep changing channels every hundred miles, but if you are using satellite radio you do not have to do that because the geographically availability of programs is not a problem. Satellite radio subscribers will soon get the chance to watch video programs as well. Both Sirius and XM services have announced their intention of introducing in the near future a variety of video satellite channels that will have some of the great advantages that are currently available to satellite radio: commercial free programs, great quality of sound and vast geographical availability.
