A few corrections:
Both D2 and D3 are composite formats, for which 4:x:x chroma sub-sampling terminology doesn't make too much sense. They both digitized analogue composite (not component) video at about 17.7Mhz.
D-5 SD was missed out, which is an uncompressed 10bit component 4:2:2 format.
BTW, D-10 is better known as MPEG IMX, an I-Frame only 4:2:2 MPEG format.
HDCAM is 3:1:1, not 4:2:2
DVCProHD is available in both 720p and 1080i variants, the PAL 1080i being different to the NTSC 1080i, and all don't have the very same compression ratios.
You can't put DV/HDV together - they use the same tape, but that's about it. You need to put HDV on a few seperate lines for it's different varieties.
PAL DVCPro is 4:1:1 (not mentioned)
HDV is not 4:1:1 in any of it's incarnations.
Hope that helps fill in some of the gaps. I'd recommend Charles Poynton's excellent book:
