1979: JVC VHD/AHD Video/Audio Disc System Prototype
VHD (Video High Density) was the video component of the JVC system, while the company hoped AHD (Audio High Density) would be adopted as the standard for digital or pulse code modulation (PCM) audio discs then being debated by a 29-company council.
The box on the right in the photo is a demodulator that would allow the player to decode PCM-encoded discs, while the box on the left is a serial interface unit for computer control. But the VHD system faced many delays and wasn't marketed until April 1983. By that time the Philips/Sony compact disc was on the market, and the AHD format never materialised.
