Hello nghi vu, you stated:

"I am not sure if you are familiar with the music service but it is actually not digital, it is analog data delivered through the same cable as my cable tv"

If what you mean is that the music is carried over an analog modulation scheme that yields digital data (such as QAM or DPSK), then I understand what you are saying. But if you mean that it is truly an analog form of data, then I would ask you to elaborate.

If what you mean is that the music is carried over an analog modulation scheme that yields digital data (such as QAM or DPSK) in support of MPEG or wav files, then I understand what you are saying. This is clearly digital in nature, albeit through the use of analog constructs. On the other hand, all digital line coding techniques, even bipolar return to zero, are subject to analog parameters in one way or another, probably in more ways than we'd want to enumerate here.

But if you mean that those music services are being delivered in a truly analog form, such as via AM or FM without undergoing digitization, then I would ask you or someone else here to elaborate.

nghi vu- I'm am familiar with it as I have the service too. Both GTE Worldwind and TimeWarner Roadrunner offer the digital music as part of their digital TV upgrade packages. I believe all MSO's nationwide give the music package away as part of their digital TV service package. I tell you this because it's so prevalant now that I don't know how you could make money off of it. I'm curious...what was your idea again?

I think what the engineer meant to say was that the music was in analog format at some point upstream of the cable company headend. Then the cable company converts it to digital in order to send it down the digital pipe to your house. In my case it still runs through my set top box(STB) first where it's converted back to analog so my stereo can play the music(your TV speakers too for that matter).

But since you mention the early date of 1994, that was well before any digital upgrades of the cable plant. And I too am curious about how you got the music package from your cable provider. Who was your cable provider back in 94 and who is it today? Do you still have the same exact black box back in 94 as you have today?

Another idea, and IMO a very good one, is to be able to listen to the digital music package over any stero in any room of the house. So I see where wireless might play a big part in this. It's a shame to have such a great selection of commerical free music in a room I don't spend that much time in. With a STB, you only have one room from which to listen to the music. It would be great if I could access the digital music from any room that has a stereo. This is an idea the MSOs are already working on. -MikeM(From Florida)
