I was messing around and tried figuring out the syllables per line. Assuming the translation i used was accurate, I got '956764956'. A quick Google search led to me finding this as the first result: https://www.walmart.com/ip/Composite-AV-CVBS-3RCA-...
Would it be possible to hook up a laptop to a TV with this and try running it through there? I honestly have no idea when it comes to converting things like this so I could be reaching here but I figured it was worth a shot.
