I have a model B Raspberry Pi running OpenELEC v4.2.1 connected by the composite output to the SCART input of my TV using one of these:


I have read that SCART can automatically change the video source on the TV by sending a voltage through pin 8 of the SCART connection, see http://hackaday.com/2011/04/26/scart-hack-automatically-selects-tvs-av-mode/.

Is there anyway to do this in OpenELEC?

Slightly misleading title since this is selecting aspect ratio, not A/V mode. Incidentally, the only kind of SCART connections for games consoles that don’t do auto-switching are the A/V composite adaptors – the tiny SCART bricks with 3 RCA sockets. [...]

That's one of the comments. The 8 pin on SCART selects the aspect ratio, and the auto-switch to the AV mode on the TV depends on the TV. Some TVs do this automatically, some not.

  • That is not the full story, as per Wikipedia the voltage applied to Pin-8 (from a source with a 1KOhm impedance) to the TV's SCART connector, does both A/V mode and aspect ratio: 0–2V means no signal, or internal bypass; 4.5V–7V (nominal 6 V) means a widescreen (16:9) signal and 9.5V–12V (nominal 12 V) means a normal (4:3) signal. – SlySven Dec 17 '15 at 18:01
