Each colour component is stored in a 16-bit word, with 4 unused high bits filled with zeros. Each n-pixel row contains n/2 green samples and n/2 blue or red samples, with alternating red and blue rows. Bytes are stored in memory in little endian order. They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these formats Each cell is one byte, high 6 bits in high bytes are 0. start + 0: B00low B00high G01low G01high B02low B02high G03low G03high start + 8: G10low G10high R11low R11high G12low G12high R13low R13high start + 16: B20low B20high G21low G21high B22low B22high G23low G23high start + 24: G30low G30high R31low R31high G32low G32high R33low R33high
