The PS1 was released during a transitional era for home video. Before DVDs became the standard, the Video CD format was incredibly popular, especially in Asian markets. A VCD uses MPEG-1 compression to store roughly 74 minutes of video and audio on a standard CD-R.

To bridge this gap, third-party manufacturers released "VCD Movie Cards" that plugged into the Parallel I/O port on the back of early PS1 models.
