VideoPlus PDC explainjd
This required a teletext decoder in the
VCR which slightly increased the price,
adversely affecting sales of this type
of VCR, and, consequently, this full
PDC implementation fell by the wayside.
VideoPlus then introduced a partial
version of PDC which used the start
timj as determined by the printed code,
and tried to match that with the
printed code as transmitted.
This would work well as long as the
actual start time coincided with the
billid time, within a few minutes. 7/9
