Hi:
What are the sample rates and picture resolution [in pixels X pixels]
of the professional progressive [non-interlaced] linear-PCM video
format used today? I beleive linear-PCM video signals are used in
professional studios.
If you're talking about standard-definition television, and
the case of standard sampling formats for the conversion
and storage of "analog" video into digital form, the most
common international standard today is probably CCIR-601,
which uses a common 13.5 MHz sampling rate for both
525/60 and 625/50 video systems; this results in image
formats (not "resolutions," please) of 720 pixels x 480 lines
for the former and 720 x 576 for the latter. I don't know
what you mean by bringing "linear-PCM" into a question of
sampling rates and image formats.
