Sony and Panasonic say they will release home 3-D television systems in 2010; Mitsubishi and JVC are reported to be working on similar products.

“TV finally becomes real” in three dimensions, said Robert Perry, an executive vice president at Panasonic. “You’re in it. It’s the next frontier.”

Perry compared the 3-D transition to the switch from black-and-white to color television and the shift from standard- to high-definition images.

ESPN is test-recording some sporting events in 3-D, using cameras with two sets of lenses, which would make football players appear to jump out of home television screens during live 3-D broadcasts.

And, although television makers haven’t released specifics, the price of 3-D TV — which requires a new television, broadcasting content and 3-D glasses — is not expected to be substantially higher than some high-definition televisions on the market now.

Still, there are skeptics who say that 3-D is not ready for prime-time home viewing.
