They're expecting the process to take around a year to complete.
With new technologies come new standards, and with 3D they're popping up all over the place. The ATSC is now working on one of their own for broadcast television to fixed and mobile devices.
Dr. Youngkown Lim of the Electronics and Telecommunication Research Institute is heading up the project, which he expects to complete in around a year. The standard will deliver 3D content on one receiver, with video for both eyes delivered at the same time and will also cover 3D content available "in non-real time" which we assume means VODs.
"The addition of 3DTV over-the-air TV broadcast transmission is part of our ongoing effort to expand the capabilities of the ATSC suite of digital television standards," says ATSC president Mark Richter. "The addition of 3DTV capability to the DTV broadcast standard will foster new broadcast services while preserving the integrity of legacy TV receivers."
