Is it possible to stream my desktop over audio system? I mean some kind of
cat /dev/fb0 > /dev/dsp?
Or to pulse-code my desktop using built-in soundcard and to stream it over optical spdif audio-out port, where on the other end its raw data could be then recoded into image with kind of sstv algorythm?
I`m interesting both on possibility of such action and existing software (m.b. pulseaudio could?)
UPD: if assume that the channel`s on 100 Mhz FM data capacity is around 100 kbit/s and rdp protocol on 1024x768 with 256 colors eats around 40 kbit/s (am I wrong?) than it is really enough to stream rdp over audiochannel. And if spdif is used than there will be no digital-to-analog-to-digital transition even. So I wonder how it could be set to input from spdif on other end (for example, my Gateway NV57 laptop has line-out 3.5 jack with built-in SPDiF, I should just to capture on it after connected the wire from source PC - ?).
