How can I determine a resolution of 4:2:2 YCbCr image?
TVP5150 will give 720 active pixels regardless of input signal. But the horizontal total will be either 864 or 858 pixels depending on signal being PAL or NTSC so that depends on your camera. You get two clocks per pixel as the data output is multiplexed between Y data and C data. C data is also multiplexed between Cb and Cr.
