Texas Instruments DLP  is developing technology that allows two people to view two different programs simultaneously while on the same TV.

TI wants to sell this chip-driven technology to be incorporated in a third-party home entertainment system for 2D, 3D or "dual view mode" on the same TV. Dual view mode, step-daughter to 3D viewing, allows two images, but two different images that are diverged (as opposed to 3D where they are converged for one affect).

At this point, each viewer would wear different glasses -- one exposing only view "A" and one for view  "B." At least one viewer would need to wear a headset in order to get the correct audio. For yor customers, this could cause severe sibling rivalry.
