Home Cinema
Home Cinema systems vary from a simple Plasma screen and satellite speaker system running off a dvd player, to a touchscreen-controlled dedicated home theatre, with projector, video server and an automatically masking screen.
These systems are designed to take away the complexity involved in watching something that should be simple.
At the touch of a button, the screen lowers (and masking adapts to correct format), the projector turns on and the movie plays.
If lighting is integrated then this will automatically adjust as the movie begin - just like the real thing.
