Berkeley Lines: 11 Re: All this discussion of conversion of television formats: I have noticed, while watching snippets of European television rebroadcast on US NTSC television (usually on news interviews), a non-smooth conversion effect. Every few seconds a frame will appear to be held for an extra long time, and then the following frame will appear jerky, as if one or more have been missed. The previous articles discussing PAL to NTSC conversion describe methods which would not seem to produce this effect. Am I seeing an artifact of a different (poorer) conversion process? Or is this perhaps an artifact of the transmission method, with frames being dropped and previous frames held because of transmission errors or a shared data channel? --Dan Halbert, ucbvax!halbert
