And basically what happens is from a studio location in New York for Sirius and from a studio location in Washington DC for XM all of the signals that you can receive on your satellite receiver are sent up to those satellites. All of them, they are all sent up at once and they are all received in return by your receiver in what is called a multiplexed mode. There is one signal that the receiver gets on that antenna that sits on deck or in your house or on the roof of your car, on the trunk of your car. You are choosing which of those channels to pick out of the sort of spaghetti strand that comes down is what happens on your little receiver unit. You choose which of those signals to pick out of the combined signals of all the channels. So they all come down at once and then your receiver picks out which ones they want. In that stream is not only the audio which is encoded proprietarily, its encoded with a special encoding that both companies use. But also included in that is a data string to tell you the name of the show, the name of song, the name of the channel, conditions for traffic and weather and so on. And the funny thing is the terrestrial radio has that available to them as well in something called the Radio Data Service. But a lot of terrestrial radio station simply don*t use it because the receivers that are RDS capable are few and far between so it*s a technology that's very, very widely used in Europe but is not very widely used here. So that*s in a nutshell how it works in terms of how the different channels are created again they are all created in individual studios or by taking feeds from program providers like us to that central location either in New York and Washington or Washington and then those are feed together upto the satellite and then down to your receiver. It*s interesting that you would ask because it*s very much the same as a Dish Network is for their television service. All of the channels are available to you. You just choose with your receiver just prior to your television, which one to use. So that's the story. It*s pretty fascinating and it*s pretty interesting that they can change the bandwidth and so on make the ones that do music a little bit wider than the ones that do talk and they can change it on the flying stuff. Of all the technology that is not built in the satellite radio is the ability to find out who is listening to what channel at what time for how long. And for all of the years and years and years the broadcast radio has been using rating systems that rely on estimates from diaries. You would think that one of the things that they would build in a satellite radio is the ability to know exactly who is listening to what station, for how long and when but no, it*s not built into the technology, kind of interesting. Quarter past the hour that's cool, we will talk about computers, the Internet, online services, websites, Macintosh wanting to hear from Macintosh people in particular tonight. Lot of things going on in the Mac space I keep getting nudged to get the 10.3.8 update and I am not quiet sure if I am ready for that what with the fact that I use ProTools on this machine. Also if you are an XP user or a 98 user we would love to hear from you as well. If you have questions about Google those of you that just planned out this week that Amazon is behind 43 things. We can talk about that as well 180039 online its Online Tonight more in a moment.
