CEA Issues Specs For 3DTV Closed Captioning, Glasses

The Consumer Electronics Association announced the publication of a standard for 3DTVs to render closed-captioning services and another for synchronizing active-shutter 3D glasses via an infrared signal.

The first spec, CEA-708.1, "Digital Television (DTV) Closed Captioning: 3D Extensions," specifies signaling to allow closed captioning to be rendered with stereoscopic 3D program content. The standard allows for a standardized method to set a value for the perceptual depth for closed-captioning text, or a series of values that change over time.

The other -- CEA-2038, "Command-Driven Analog IR-Synchronized Active Eyewear" -- defines a way for controlling "active" 3D glasses worn by viewers using an infrared signal sent by a TV set.
