Los Angeles - Consumers who subscribe to cable-TV service will get a simplified home theater experience if cable operators adopt THX Media Director technology unveiled here by THX at The Cable Show 2010.

The technology delivers metadata over a cable network to a cable settop box, enabling compatible TVs and home audio systems to automatically select the correct aspect ratio, color space, surround-sound modes, and other settings designed to ensure that the filmmaker's artistic intent comes through a home theater system. It would also automatically switch between 2D and 3D playback, the company said.

The technology can be added to the installed base of set-top boxes (STB) via a firmware update, THX added.
