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?

Step 1:

Use the S-Video output for video out and the laptop phone conect to audio out.
