Any serial format but the 10-bit format, is virtually extinct. In the early days of serial digital interfaces, reducing the datarate could significantly reduce the cost and/or increase the reliability of a link, so the lower-bitrate versions made sense.
192:
Today, the 10-bit interface is extremely reliable, inexpensive, and ubiquitous; the other interfaces are mainly of historical interest. (That, and there are still many concessions to the 8-bit interface in other standrds, such as
181:
I have studied the latest version ot the Rec. ITU-R BT.601-5 and it does not determine the serial format component order. The Serial format and component order is defined in Rec. ITU-R BT.656 (SDI, Serial
Digital Interface). --

I have not found in the standard than any chroma sample could be coded with four bits, it just mentions that samples could be optionally coded with 10 bits. Where do these 4 bits per chroma sample come from ? --
156:
You seem to speak from experience, so what you say is probably what happens in practice. I was trying to summarize what the spec. says, regardless of whether anybody uses all these format variants or not. --

152:"optionally encoded"? My impression is that the 270 Mbit/s format is universal for interconnect. Various sub- and super-sets are used as derived formats, but 270 is used for patching.

Is the storage order definitely Y1:Cb:Y2:Cr? I have seen Cb:Y1:Cr:Y2 used also, but I don't have the spec in front of me so I don't know what's definitive...

Does anyone have a chromaticity diagram showing the gamut of 601 that we can add here? I feel it is somewhat lacking when compared to the 709 article.

225:
Why is this article still called "CCIR 601" if the official name has been changed to "ITU-R BT.601"? I propose it be moved to "ITU-R BT.601"
303:
The color encoding system is known as YUV 4:2:2, that being the ratio of Y:Cb:Cr samples (luminance data:blue chroma data:red chroma data).

Although the numbers are the same in this example, the implication for YUV 4:2:0 is clearly false. --
