- * <--- 160 or 176 pairs of RA,RB bytes ----->
- * *-----------------------------------------* \
- * | RA0 | RB0 | RA1 | RB1 | ... | RAx | RBx |  \   This is pair of horizontal lines,

- * |=====+=====+=====+=====+ ... +=====+=====| /    240 or 288 lines after deinterlacing.

- * Each group of FOUR bytes (RAi, RBi, Bi, Gi) where i=0..frame_width/2-1

- * seemingly represent R component, but slightly vary in value (so that
- * the picture looks a bit colored if one or another is used). I use
- * them both as R component in attempt to at least partially recover the
