Ross Miller reporting for The Verge:

The "multi view" concept isn't new, even if it still lacks a quick-and-easy description. In essence, it's two videos signals stacked on one another — using special polarizing glasses not entirely unlike 3D specs to "isolate" a (two-dimensional) signal and thereby allowing two or more people to watch different videos on the same TV. LG has it with Dual Play and Sony with PlayStation 3D Display.
Even though Miller says the concept isn't anything new, I've never heard of it before and find it fascinating.
