Slow Scan TV on a 2017 CD

SSTV (Slow Scan TV), I’ve already talked about it last year, with an album from Aphex Twin that’s quite old. But the Italian artist Caparezza put some on a CD in 2017, with Prisoner 709.

Instead of repeating all the previous articles each time, I’ll refer you to the dedicated page, which explains what I do with vinyl records and lists all the pages containing programs, explanations, etc.


I won’t repeat myself, you can go read the text from the previous article. The SSTV audio is at the end of the 16th track on the CD. There’s about four minutes of music, then three minutes of silence, and finally about two minutes of SSTV. I didn’t see any reference on the cover, but the Discogs page lists its presence.

I used the same program for iPad (but on Mac) as last time, and the encoding is the same: Martin M1. For playback, I did it in a basic way again: an external sound card and a jack cable connecting the output to the input. The image appears gradually (that’s the principle of Slow Scan TV) and shows text in Italian. It’s evidently the message from prisoner 709, the album’s name.
