Video Output from TV

Post by hogi » Wed May 01, 2013 6:50 pm

Hello,

For a project of mine (currently only in idea state) i'd need to know what the TV is currently displaying. The quality doesn't matter or wether it's an analogue or digital signal.

I have an UE40es5700 and i already found out that i can get an CVBS signal out of the scart connector. But this signal is only available when using the tuner. It works both with DVB-T and DVT-S(2) (and presumably DVB-C) while watching SD or HD programms. But as soon as i switch to USB playback or network streaming the signal goes black.

Does anyone know of any Service Menu setting to enable output with all sources. Or is it maybe not even possible due to circuit design?
Is there any other way to output all video content the TV generates (tuner and video playback from usb or network)? Like as a stream over network?

Thanks for you input,
hogi

What you get on the scart connector is an analogic signal that is available from the tuner (or better, after DVB protocol decoding).
This is most likely a one way process only.
When you use a USB source (or network), this process is not active probably because the job is done by the GPU and using other codec.
I guess that most likely what you are looking is not possible even if I understand that this might be limiting your needs (older TV were doing it).
What happens if you take the signal from HDMI or 3 way digital RCA ?
