Talk:Time base correction

Timebase or Time base?
Title uses timebase. Lead uses time base. Body uses both. --Kvng (talk) 01:32, 1 September 2011 (UTC)


 * Back in September, changed article title to Time base.... I've just edited the article body to match. --Kvng (talk) 03:50, 22 March 2012 (UTC)

Dropout Compensation?
The article mentions DOC (Dropout Compensation), but I'm not sure how this should be implementable within a TBC, which is externally connected to the video-signal. Dropouts are caused if the RF-Signal stored on the tape cannot be read back accurately (e.g. due to tape-defects or dust), which causes the RF-level to drop beyond a certain value. DOC-circuits are usually built into the replayers themselves, as they need to have access to the un-demodulated RF-signal in order to work. If an external TBC receives only the demodulated video signal (CVBS, Y/C, ...), it is already too late. Please correct me, if I'm wrong, but I think that DOC in an external TBC is not possible.

There were special RF outputs on some umatic recorders that fed a signal to the external TBC's DOC input. --StevenBradford (talk) 04:42, 26 July 2014 (UTC)
