The basic specifications of a CD-i Player: What was the speed, the memory inside and the resolution of the video output?

Let's review back some basic specifications of the CD-i platform. The CD-i or Compact Disc Interactive, created by Philips, Sony and Matsushita, was the first multimedia CD player in the world. It was capable of playing full motion videos from a Video-CD (using the Digital Video Cartridge extension – DVC), watching your favourite photos on a Photo-CD, listening to music from a standard Audio-CD and of course playing games, educational, professional and multimedia titles thanks to the CD-i standard. You are also able to sing karaoke songs by playing CD+Graphics discs, listening to 8 hours of background music on a single disc thanks to CD-BGM, bringing hybrid CD's that offer CD-Audio content and CD-i ready multimedia thanks to CD-i Ready, and it also allows some supporting CD formats like CD-Text, CD-Midi and CD-i Bridge. The CD-i Ready format is a type of bridge format, also designed by Philips, that defines discs compatible with CD Digital audio players and CD-i players. This format puts CD-i software and data into the pregap of Track 1. The CD-i Bridge format, defined in Philips' White Book, is a transitional format allowing bridge discs to be played both on CD-ROM drives and on CD-i players. The CD-i format was developed by Philips, Sony and Matsushita back in 1986, and is specified in the Green Book (“Red book” for the audio CD and “Yellow book” for the CD ROM) which contains all the specifications of a CD-i player and protocols. Compared to the Yellow Book (specification for CD-ROM), the Green Book CD-i standard solves synchronisation problems by interleaving audio and video information on a single track.
