CES-UPDATE 1-Panasonic, DirecTV team up on 3D

* Panasonic, DirecTV to launch 3D channels in June

* Says sole end-to-end 3D content and hardware provider

LAS VEGAS Jan 6 (Reuters) - Japan's Panasonic Corp (6752.T) and DirecTV Group (DTV.O), the top U.S. satellite TV provider, will together launch three high-definition 3D channels by June to try and jump-start demand for 3D TVs and content.

Panasonic is the world's biggest maker of plasma TVs, which has been beaten out by LCD TVs in market share, and it hopes an added dimension will help it reverse brutal price falls and dwindling margins.

"Now, so many other major brands have announced 3D products," Yoshi Yamada, CEO of Panasonic North America, said at a news conference attended by 3D movie "Avatar" producer Jon Landau at the Consumer Electronics Show on Wednesday.

"But we will be the only end-to-end 3D provider, from the cameras to the TVs to the editing."

The exclusive agreement includes 3D broadcasts of Major League Baseball's All-Star Games. DirecTV will further work on additional broadcasts by networks including Viacom Inc's VIAb.N MTV, CBS Corp's (CBS.N) CBS, and General Electric Co's (GE.N) NBC, the two companies said.
