YCbCr 4:2:0 - Dok - Apr 1 10:19:00 2004

Hi! How does the 4:2:0 Chrominance format look like in data stream? Say I have these pixels... Y0 Y1 Y4 Y5 ... Cb0/Cr0 Cb1/Cr1 ... Y2 Y3 Y6 Y7 ... . . . Is it like, Y0,Y1,Y2,Y3,Cb0,Cr0,Y4,Y5,Y6,Y7,Cb1,Cr1.... or something else? Thanks, Dok __________________________________ |

most of the time, all the Y components are written first later Cb and then Cr. i.e. Y0 Y1 Y4 Y5...Cb0,Cb1,...Cr0,Cr1,... Note that all the components are written row wise... -Mahesh ----Original Message Follows---- From: Dok <> To: Subject: [imagedsp] YCbCr 4:2:0 Date: Thu, 1 Apr 2004 02:19:39 -0800 (PST) Hi!
