VNC-like Remote desktop for J2ME?
I was wondering if any of you use a mobile phone to remotely control the car-pc?
I did a bit of searching and found JM2PC http://www.jm2pc.com/jm2pc/jm2pc.faces
This is able to connect to the PC through bluetooth or internet (gprs/3G), and control it, with some pretty useful functions too, like file transfer. The only drawback is that it only makes a screen capture when requested. So... it's not real-time.
I'm after something like VNC, of course written for J2ME and using, first of all bluetooth, and then maybe gprs etc.
If there isn't such a software, it could be written if someone is interested. JM2PC is open source, it could be a starting point.
I made some calculations: a screen-capture at 320x240 in different color depths and formats:
Assuming a 20kB jpg screenshot, a continuous stream of 10 frames per second would require a bandwidth of 200kB/s or 1.6Mbits/s.
This means an average bluetooth adapter (2Mbps) or 3G internet connection. But the jpg compression doesn't need all the 24bpp and 90% quality so it could be more compressed. 10x a 5kB frame is just 50kBps or 400kbps...
Other (maybe better) ways to achieve mobile->car-pc control is using WLAN. But for now, the most common mobile phones have bluetooth and J2ME.
So, does someone already use a software like this, or is someone interested in developing it?
