3D TV
While we are on the subject of stereographics, let's go one step farther. One pro-
posal for 3D television (“3DTV”) has been a technique called “SmoothPicture”
[21] which transmits a single stereo image by spatially interlacing the left and
right images into it, as shown in Figure 11.9. Each separate image is deci-
mated in complementary checkerboard paterns before being combined. A
