- At least here in Germany I once saw one, by Panasonic if I remember correctly.
- This one was able to accept either standard PAL-BG/I/H/M, SECAM-France,
- SECAM-"East", NTSC-50Hz and NTSC-60Hz and some other minor systems,
- according to the ad sheet. I am not sure about the internal format, but it has
- been said to be a converter, i.e. emit the different standards as well (I
- don't have detailed technical data, not even the type ID, so don't ask me).
- I was quite expensive, about 5000 DM, which is about 3300 USD (oh, i forgot,
- now about 3600 USD ;-)
-
- I'd guess that such a beast is available anywhere in world, although it will
- not be requested very much in countries where there are no different concurrent
- standards.
-
- Also note, that there is a chip set by Philips named Multi-Standard-Colour
- Decoder, which may automatically synchronizes SECAM-*, PAL-* and NTSC-50Hz
- (4.43 and 3.58 MHz carriers) to RGB. From RGB it is a quite simple step to
- go back to PAL and NTSC, by using a PAL/NTSC-Encoder named TPE1178 (also
- Philips?). These chip sets unfortunately do not convert the line frequencies.
- The 10Hz difference usually need a dual port video memory, in a similiar
- way to synchronize two *free running* video signals (Building a *genlock* with
- one synchronizable source is much simpler).
- If someone is interested in the converter chip set, I'll look up the part
- numbers. Send me mail, I don't read this group very often.

- P.S.: I am not involved in video/TV business; I just bought a video-mixer kit
- for some purposes, which had these circuits in it.
