Avatar's run in theaters is just about done. But its influence continues to spread. The success of the 3D film has electronics manufacturers again looking at the possibility of 3D TV. Toshiba and Sony have announced 3D models, and cable channels like the Discovery Channel are producing 3D programming. In China electronics company TCL has released a 3D TV that doesn't require special glasses. And the State Administration of Radio, Film and Television says China will be producing 3D programs this year.

3D TV has been around since the 1950's, but has never really taken off. One problem is the viewer experience, and the need to wear those funny glasses. Another problem is the added expense of producing 3D programs. In addition to those well-known problems, there might also be health problems. Some viewers of 3D films experience headaches, nausea, and even seizures.

Is 3D technology ready for the home market? Are electronics manufacturers pushing the technology too fast?

Ni hao, you're listening to  People In the Know, bringing you insights into the headline news in China and around the world, online at crienglish.com, and here on China Radio International.

In today's program we'll discuss the future of 3D TV. So let's get started.

First, we'll speak with Mr. Michael Zhang, telecom research manager at In-Stat China.

And after a short break, we'll talk to a digital technology expert at the University of Sydney.

There are various platforms for producing 3D effects at home. Some require glasses, others do not. But all of them use the same basic trick to fool the brain. That trick can cause some problems.

For more we go now to Mr. Mark Pesce, honorary associate at the Digital Cultures Program at the University of Sydney.

Here's an interview I did for China Radio this week, about the evils of 3DTV.
