Primary quesion: Does anyone out there know of a way to
to convert video cassettes recorded in
a country using PAL so that they would
playback here ?? and Vice versa ???
I know of a SONY tv that automatically selects the receiving
mode between PAL and NTSC. Would it be possible to play a
cassette recorded in PAL directly using this set ??
Would it be possible to record using a camera such that the
cassette can be played with PAL ??
Please mail your responses direct please. Postings at PSUVM
seldom last more than 12/24 hours and I may miss them.
I promise to post a summary if the response is good !!
Thanks !!
Keep Smiling !!! --Indra K. Singhal

Converting a signal from NTSC to PAL or from PAL to NTSC is a major undertaking, and requires some sort of standards converter. These (usually rather large) pieces of equipment cost thousands of dollars. I work at Ampex, where we develop many types of professional video equipment, and I've never seen a standards converter in our labs. They just cost too much to have around. Your Sony TV which will display both NTSC and PAL won't do you any good unless you have a PAL VCR to play the tape with. The PAL and NTSC formats are rather incompatible: NTSC is 525 lines per frame, 30 frames per second, with a 2-frame color sequence. PAL is 625 lines per frame, 25 frames per second, with a 4-frame color sequence. Because of these differences, the recorded tapes, and the VCR's are different.
