Re: Ambilight / Atmolight

Hello,
I am also looking for an ambilight for my Samy Ue7700C. By scanning the www I found so much solutions for controlling LED-stripes. I think many of you found that too.
All in all there are tow ways.
1. Controlling the LEDs by a computer (pc, arduino, dreambox, vu+ ore something else) which also give the video signal to TV.
2. Controlling the LEDs by a computer (pc, arduino or something else) which grab the video signal.
the longest compilation is therefor
HDMI source --> HDMI Splitter --> HDMI to composite Converter-->composite usb videograbber-->computer-->LED-controller
For both you need a external video source, but I'm using the internal tuner or streaming videos by DLNA.
My intention was to use the analog video out of the TV. That works very good, if you are looking TV content not protected by HD+.
If you switch to a protected HD+ channel, sometimes there is a signal on the video out for a few seconds too. So I guess it's not coded but rather switched off.
I don't know how, but may be anyone here can modify the FW that the analog video out does not switch off?
Than you can use a simple composite usb video grabber with, for example, a Raspberry Pi to control the LEDs.
Maybe someone can give some Ideas how to get DLNA streamed and HD+ contend out of the video out?
Otherwise I will follow this thread further and hope some one will find a solution to get the picture information by the usb port.
