Thanks, Dave....you took the words right out of my mouth.
I recall some time ago on the TIG, the DCT compression of popular standard
def formats being compared to that lossless compression used to pack
computer files, i.e RLE, LZW, etc.
Your post helps to clarify this issue and points out what every video
professional should be familiar with.
I would suggest to anyone needing more clarification, to get a copy of
Peter Symes' book on compression.
