simple, lossless without further rounding/truncating (no lsb/error will be generated)
like:
YCgCo is lossless (it has no lsb)
YCbCr (infinite precision) is lossless (it has no lsb, infinite precision is free from any sort of rounding/truncating)
YCbCr (finite precision) is lossy (it does have lsb/errors, and lossy without further/the final rounding)
