Englewood Cliffs, N.J. - LG has developed proprietary 3D sound technology that it will incorporate in two home-theater-in-a-box (HTiB) systems to synchronize audio with 3D picture depth when playing back 3D video from Blu-ray discs and broadcast sources.
The two HTiBs will be available in the first half, including the top-end BH9420PW.
A statement issued by LG in Korea incorrectly stated that four HTiBs to be introduced at CES would offer the 3D sound feature.
The technology, called 3D Sound Zooming, "constantly synchronizes sound output with the location and movement of the on-screen 3D images," the company said. "3D Sound
Zooming is capable of generating variety of depth in sound based on a complex algorithm that analyzes the varying depth of numerous on-screen objects displayed [on a 3D TV]."
One of the HTiBs with the technology, the BH9420PW, is due in stores in March.
Both HTiBs will also be the company's first with an extra driver in each front and rear left-right speaker to create a more enveloping, denser soundfield around listeners, the company said. The extra driver fires upward in a niche in the baffle, and its sound is then deflected out of the baffle over a wide angle after hitting an inverted cone.
The HTiB also features Sound Field Expansion, which expand the horizontal sound field.
Both HTiBs will also incorporate LG's SmartTV platform to access online audio and video services.
