Music TR9C1710 (Video RAMDAC)
Part number : STV8438CV
Manufacture : ST Microelectronics
Specification(s)
Description : 8-Bit Triple DAC with Analog Switch
Package : PQFP44
MC68340 : Integrated Processor with DMA
The MC68340 is a high-performance 32-bit integrated processor with direct memory access (DMA), combining an enhanced M68000-compatible processor, 32-bit DMA, and other peripheral subsystems on a single integrated circuit. The MC68340 CPU32 delivers 32-bit CISC processor performance from a lower cost 16-bit memory system. The combination of peripherals offered in the MC68340 can be found in a diverse range of microprocessor-based systems. Systems requiring very high-speed block transfers of data can benefit from the MC68340.

Board
Difficult to make things out on this one, but the SCSI socket is clear to see - this is where the CDROM drive hooks in
CPU
Again, a 68k processor
DSP - Cobra 3
Just a board to decode the audio from the CD video. no ROM's feed it.
GLUE - No idea
Just some logic to sync audio with video with realtime graphics? - Clearly something is needed, as three separate boards are used to process this.
Music - video RAMDAC - have nothing extra to add, this clearly plays the video portion.
SCSI controller - just like in any PC
Sound
All related to the Yamaha YMZ280B-F, a very good music/PCM chip, probably not used to full potential here.
CD-ROM - I'm prepared to put money on Telly Addicts and TOTP being like this, with some minor alterations.
Ordinary ISO standard CDROM with 2048 byte sectors. Can be read on a PC to give MPEG-1 video files (.mpg) at 352x288 pixel resolution, which would probably expand to full screen - some have their own soundtracks, others subtitles. The frame rate of the video is 25fps, and the audio (where available) is 44KHz Stereo, 128Kbps MPEG Layer II (Which is not supported by Sellenoff's Capcom sound driver). Some graphics are stored encoded as .gfx files, whereas clip list data is either stored as an .stl file (listing 'number of clips' and clip name) or in .clp files (same, but larger - different round?)
Final.lis is a list of the questions asked in the end game, where players are asked to match the programme to the channel it is broadcasted on (Very easy to decode, listed in numerical order of channel as channel (space) programme name (not alphabetical, but accessed at random - end marker is blank line, Channel '5' is radio, since there was no Five TV in those days.) (Why am I telling you this - it's practically an emptier.)
Questions are listed by clip, in .QQQ files, encrypted.
.SEQ files are 'sequences' instructions to the video board, in the form of renamed .MPG files, again 352x288, MPEG-1.
TEST.TXT - suggests the content of a prototype version, which was expanded to make this. If the volume name is to be believed I may be related to the person who compiled this (though it's a big clan, highly unlikely ;))
