An extremely rare demo reel, likely from 1985, has surfaced online showing off the first commercial HDTV system from Sony.
The footage, digitised from a rare still-working Sony HDV-1000 reel-to-reel video recorder, boasts 1035i resolution and shows a traditional Japanese festival.
It was likely filmed in the 1980s, a time when Japanese companies had already been experimenting with HDTV technologies for over two decades.
This makes the video, uploaded to YouTube, one of the oldest HD videos viewable online and offers a fascinating insight into the history of broadcasting.
The fairly low-resolution nature of the video belies its 1985 origins, but it is a groundbreaking look at a moment in broadcast history.
