I have a Sony bluetooth headset that I use after 10 pm to not bather other poeple, it works fine with playstation 3 however when I want to watch TV my satellite receiver have only coaxial digital output so called SPDIF all what I need is a bluetooth transmetter devise that transmit the digital audio to my bluetooth headset even in 2 channels, I know there is a lot of analog bluetooth transmitters out there but I want the digital type, It may never existed but just wondering if someone come across a do it yourself magazine or school project using a specific mico chip or pre designed circuit, thanks

The digital output from your tv is not digital audio - yet.

It is an undecoded Dolby Digital bitstream and is only available from an HD channel. First you would have to decode the bitstream to pcm and then find a way to transmit that pcm signal to your head set. You might want to look and see what is available for computers, otherwise I doubt you will find anything.

Isn't bluetooth a packet based protocol like IP? I think it's quite a bit more complex than strapping an antenna to the spdif port, like piles of stacks, error correction management, routing etc.

There was a pretty cool thing I used to use in my car which could transmit a low level FM signal from the output of an ipod, cdplayer , whatever. You could dial it in on the car radio. It was essentially your own little pirate radio station but at such low power as to fly under the FCC radar.

You'd need a portable FM radio w/ headphone jack but maybe it would help to liberate you a little more. My freind and I would use one to point our office boomboxes at his car which had Sirius radio using one of these gadgets with our ehem custom antenna tied to it. It actually worked pretty well and we were pushing the range much further than it was ever intended to be used. Also probably were breaking some FCC regs with our antenna but it was fun for a couple weeks. Maybe I shouldn't be posting what we did but we only did it for a couple weeks until it was boring and no fun anymore. Even with the fancy antenna I made (a carefully tuned piece of wire lol) you'd be hard pressed to get more than about 50yards out of one of those things without adding a linear amp and going to an even better antenna.

Ah jeez. You'd think by reading my reply I didn't even read you post.

I have no idea about the answer to the question you actually asked. So sorry.

What the heck satellite box doesn't have analog outputs?

Are you sure it doesn't have analog outs? It has to have analog out...

Bluetooth has limited bandwidth, so bitstream audio is probably out of the question (today). You're listening to "stereo" via headphones anyway... digital should not be that important IMO.

As suggested, use the analog audio outputs of the satellite receiver... which all of them have.

Thank you guys for the help, I will just go with analog adapter I guess I don't think it will be that much diffrence in quality, eventhough the audio will be converted twice D to A at the satellite receiver and A to D at the bluetooth adapter, not to mention D to A again at the headset but that's the human nature we can't change our ears. Anyways I can live with that it's only after 10pm.

Glad that you see it our way.
(I guess you found the analog audio outputs on your satellite receiver.)

I'm just picky when it comes to quality, thanks

I bought a nice bluetooth headset yesterday and one of the reasons was to not disturb my wife with sounds of battlefield while she is trying to sleep but to my shock, I failed to find any option in PS3 settings that will make ALL audio go through the headset rather than just chat. So I'm wondering how did you do that?
