Philips' version indication method

Philips uses its version indication method for two reasons: to indicate the region for which a specific product is intented, and to indicate a revision change. The version is indicated behind a slash after the initial type number, eg. CDI 670/00. It is printed on the type number indication at the back or bottom of a device. You can never tell which version a device is by looking at the type numer which is printed on the front, since these do not include the version number.

The numbers below 20 indicate the region for which a device was adapted. Mostly, changes consist of a different voltage or TV broadcast system, but they might include more regional changes. The most important regions used are:

/00 Europe mainland
/05 UK
/11 Japan
/17 US

Numbers above 19 indicate versions. Usually 20 is added for each follow-up version, eg. /20, /40 and /60. Differences may for example consist of the usage of a different PCB, usually there are no big changes that are important to the customer. The region code number is added to the version number, resulting in a unique number that describes the region code and the revision change. For example /37 means a /20 version adapted for the American market (because the US indication 17 was added).

In this CD-i players overview, I only indicated different revision changes, and not all regional versions that were available. Please note that not all devices are available for all regions. Some players were only made available in a standard /00 version.
