According to our crack TV marketing group that has sold equipment
into the PRC, the TV standard they are using is PAL-D. This is
similar to what Western Europe, except France, is using. The -D
standard uses a wider video to aural spacing for more video
bandwidth plus more group delay pre-correction. This involves
the transmitted signal only and the base band signal is identical
to European PAL. Tapes recorded on a PAL machine will work in
China. They use 625 line, 25 fps interlaced. Power mains are
generally 220 VAC, 50 Hz and a European power cord will usually
work if you have to send them hardware.
There are a number of duplicating companies in the LA area that
can dupe tapes to this format. I suggest looking in an LA
Yellow Pages directory.
