Pretty simple. VCD player has a few main components: 1) CD reader (any cheap CD-ROM drive will do, 1X is all required) 2) a decoder (in embedded firmware) to decode MPEG stream to video 3) a video graphic circuitry with audio and TV-OUT All these are controlled by a little micro processor. The CD reader read the MPEG stream from the CD media, the microcontroller then decode that stream to put data in a video buffer which is display by the video graphic circuitry.
