Line By Line, Checker Pattern (Field Sequential), Frame Sequential
A sequential 3D TV can display sequential 3D, this means the TV converts it.
Blu-ray outputs the video at 1080p 24 frames per second, per eye; or 48 frames per second. This signal
goes to the TV but the glasses are what ensures each eye sees the correct image.
The side by side systems, a single 1080p frame that holds both the right and left eye's images is sent at
24 frames per second. The TV receives this signal, splits it into two frames, displays them sequentially
and then stretches them out.
This is not as good as Blu-ray, but it uses way less bandwidth and makes it so that the TV Station (Like
DirecTV) can just release a firmware update instead of replacing all the set-top boxes. It is expected that
cable companies will use the same technique.
Auto-Stereoscopic TV is the future. The 3D image is created without the need for glasses, but
this is 10 to 15 years away.
