The required "wiggling" is easier when converting between NTSC and PAL-M than when converting between either of those 525-line standards and a 625-line standard like PAL-N. In the former, all you have to do is demod-remod the color, while in the latter you also have to change the timebase. In any case, multi-standard TVs and VCRs (NTSC/PAL-M/PAL-N) are pretty much the norm in S. America, and they're not expensive. -- Frank >----- Original Message ----- >From: "Mark Schubin" <tvmark@xxxxxxxxxxxxx> >To: <opendtv@xxxxxxxxxxxxx> >Sent: Monday, July 25, 2005 10:04 AM >Subject: [opendtv] Re: Due Date for Responses to the ,DTV-to-NTSC Converter >Box RFQ Extended to July 29 >> Not exactly. >> >> NTSC-M: 3.579545 MHz >> PAL-M: 3.5761149 MHz >> PAL-N: 3.58205625 MHz >> >> >> FYI, the NTSC-N that used to be broadcast in Barbados was 3.585937. >> >> Also FYI, the 1964 SECAM western-hemisphere proposals were as follows: >> M - unmodulated red: 3.493007, unmodulated blue: 3.382867 >> N - unmodulated red: 3.5, unmodulated blue: 3.390625 >> >> TTFN, >> Mark >> >> >> John Willkie wrote: >> >> >I stand corrected.
