Today I came across a relevant situation. I was necessary to show a Microsoft PowerPoint presentation an a TV. But the TV and the laptor were 50 meters away, the laptop could not be places near the TV and the only cable that was installed between the two was a coaxial RF cable. The only laptop output that could be used was an S-Video.
How to convert S-Video to RF only with the existing equipment?
Use the S-Video output for video out and the laptop phone conect to audio out.
Convert the S-Video signal to RCA
Connect both signals to a RCA input of a DVD Recorder
Connect the SCART output of the DVD recorder to the SCART input of an VHS Recorder
Connect the SCART output of the VHS Recorder to a TV to check the signal send and the RF output to the RF cable that goes to the TV.
Tune the channel on the destination TV
