The concept of autostereoscopic, or glasses-free 3DTV, could gain some momentum next week at an event that the Consumer Electronics Association is holding in New York.

Philadelphia-based Stream TV Networks plans to hold a press conference at the CEA Line Shows expo on June 26, where the company says it will demonstrate a 42-inch autostereoscopic TV that it has built with Toshiba. Stream TV says it'll also demonstrate products that allow viewers to convert satellite TV content to 3D programming that won't require glasses, and 3D content on Apple's iPad that won't require 3D glasses.

Following the success of James Cameron's Avatar in 2009, several cable networks and distributors invested in 3D programming, including ESPN, Discovery Communications and DirecTV. But the 3D programming available on cable and satellite networks today requires subscribers to wear bulky and expensive 3D glasses, which has limited the popularity of 3D programming.

Glasses-free 3DTVs could make it easier for viewers to watch 3D programming, but the technology is expensive. The first autostereoscopic 3DTVs that Toshiba began selling overseas last year cost more than $10,000.
