YCbCr422P supports ?

I have trouble in displaying YCbCr422P format pic by HDMI, but it is ok for YCbCr422 format .
So does TX1 support YCbCr422P format? Or how does it organize YCbCr422P pic datas?My YCbCr422P pic datas are organized with all Y component datas first, then all Cb component datas , last is all Cr component datas .

The Jetson TX1 does support YCbCr422P (planar) input surfaces. However, do note that the Jetson TX1 does not support YCbCr422 output. All input pixel formats are converted to RGB before being sent out over the TX1’s display interfaces.
