TV sound sub carrier automatically detected?
Hi, I'm currently in the UK (PAL-G?), using a sony-trinitron, but soon
moving to Switzerland, where it's PAL-I (or maybe I've got them the wrong way around). Will a reasonably modern Sony Trinitron tv detect automatically the sound sub carrier change or does it need manual twiddling (by a professional). Do other modern TV's generally detect. I have another TV, but I can't remember the manufacturer, maybe ITT. thanks JB |

I sincerely doubt it, if it did autodetect, that would be a feature and would
be touted as such. If the set isn't designed for it, it may be a bit more than tweaking, it may be the replacement of ceramic filter, and possibly toggling certain pins of the jungle IC. If your new sound carrier is going to be closer to the video carrier it's also possible there may be some mods in the chroma and video circuits. Also if there is any difference in the line rate you might need a mod for the stereo decoder. This does nothing for your archived videos, and if you have and use a camcorder that's a new monkeywrench into the works. You might want to leave it how it is and pickup even a small set in Switzerland to watch local braodcasts. If you got satellite and a billing address in the UK you could just re-aim it I would think a multi-rate/multi-system TV would be more avaivable in Switzerland, but I've gleaned this from things I've heard, I have no actual knowledge. I just think it's likely. If you want, research the actual differences between the systems. If you tell me that I can give you an informed technical opinion. I don't work on anything but NTSC usually. Anyway, sorry I don't have better answers at this time, but hopefully I gave you an idea or two. After I get out of the NG I might do a bit of research and find something solid. JURB |

Thanks. I expect I'll get myself a satellite receiver and watch free to air
channels via the SCART lead! I'll wait until I get there and make a decision about what to watch on native broadcasts.. JB "JURB6006" wrote in message ...
