IBC to deliver transatlantic HD stereoscopic 3-D broadcast

More than 1000 delegates will witness a historic transatlantic interview conducted in HD stereoscopic 3-D during IBC2008.

Elizabeth Daley, professor and dean of the USC School of Cinematic Arts in Los Angeles, will speak with DreamWorks Animation CEO Jeffrey Katzenberg Sunday, Sept. 14. Los Angeles-based 3Ality Digital will be shoot the interview with multicamera stereoscopic equipment and package it for delivery by satellite service company Arqiva to Amsterdam.

Three-dimensional movies have grown in popularity at cinemas, multiplying box office revenues in 3-D-equipped theaters, but live transmission has remained a challenge.

According to 3Ality CEO Steven Schklair, a particularly difficult requirement of transmitting a live event in stereoscopic 3-D is keeping the parallel signals needed to create the 3-D illusion in perfect synchronization. “That’s a special challenge over satellite links where atmospheric conditions can be problematic,” he said.

To overcome the challenges, 3Ality has developed a solution in which the 3-D signals are multiplexed into a single 2-D signal for transmission, he explained. At the receiving end, the 2-D signal is unwrapped into a 3-D picture. According to Schklair, his company has used this technique in the past, but never over a long, international link.

The interview will be shot with two 3Ality-developed 3-D stereoscopic camera rigs. 3Ality has chosen to shoot the interview with two camera rigs to demonstrate that 3-D images can be cut and mixed live, he said.

Inside the RAI Auditorium where the 3-D interview will be screened, the 3Ality decoder will pass the left and right eye signals to Christie Digital Cinema projectors.

Those attending the presentation will be asked to wear a pair of specially polarized over-glasses from Real D to view the stereoscopic image. Real D manages the separate images with a special adapter that fits on the projector, which then transmits the left and right eye images through the glasses to the viewer, said Joshua Greer, company president.
