Video Output Notes

CD-i players offer various video outputs depending on the model, version and revision^[1].

• RF (mainly on UK and US units, but also on early EU units). Later models (Mono III and later mainboards) have a +5 V output next to the Composite output, to be used with an adapter.
• Composite video (all models)
• S-Video (mainly US and early EU/UK units). Later models (Mono III and later mainboards) output either S-Video (+Composite) or RGB (+Composite). Both are not possible.
• RGB via SCART (all large stationary EU/UK models, e.g. CDI2xx and others, have native RGB output via SCART)
• RGB via DE-9, DE-15 or proprietary connectors (only on early portable, professional and authoring models, e.g., 310/350/360, 18x, 60x)

RGB

All stationary Philips/GoldStar/LG CD-i players that don't already have an RGB connector can be modified for RGB output. Guides for RGB modding can be found on the CD-i landing page.

There are two video encoder families^[2], depending on the mainboard^[3]:

Sony CXA1145P/M

(Mono II and earlier mainboards)

You can either add the missing components on the mainboard to recreate the original Philips circuit (see service manuals^[4] for parts) or tap the video encoder directly.

If you choose the latter option, keep in mind that CSync is output as TTL sync, and therefore requires a 470 Ω resistor and 220 µF capacitor on the sync line to be safe for consumer devices.

Brooktree BT9106 & BT9107 / BT9108

(Mono III and later mainboards)

You can either add the missing components to the mainboard to recreate the original Philips circuit^[5] (does not apply to top loading players like the 450), or tap the video encoder directly using a CD-i-RGB.

Note that you will lose the S-Video output when you enable the RGB output.

Checking Color Accuracy

When you are done with the modification, check the EBU color bars in the Service Shell and adjust the modification if necessary.
