No info on modulation?[edit]

I'm missing nformation on the carriers used. The article mentions the L+R/L-R format, optional extra channelsand a pilot tone, but gives no information how the extra channels are actually carried: for example similar to FM radio or using SSB. —Preceding unsigned comment added by 217.19.29.156 (talk) 14:51, 17 January 2010 (UTC)

AM suppressed carrier, like FM stereo, but with a 15734Hz pilot, instead of 19kHz. and using the TV horizontal rate as the source for the pilot. Gah4 (talk) 23:45, 19 February 2017 (UTC)

PBS Stereo Tags[edit]

PBS dosen't have it's own stereo tag. PBS stations often use stereo disclaimers during or after the opening sequence. For example:

On Reading Rainbow (began stereo episodes in 1984 part-time, full time in 1988) - the stereo tag appears after the "hosted by LEVAR BURTON" text fades out.

Sesame Street (began 1992) has theirs during a cold open segment. If there is no cold open segment, the stereo tag appears after the opening sequence. ACMEWikiNet (talk) 14:53, 21 February 2012 (UTC)

dbx[edit]

I always knew that dbx was used for SAP, but I didn't know that it was also used for the stereo subcarrier. Is there a reference for that? Gah4 (talk) 23:47, 19 February 2017 (UTC)
