SAN JOSE, Calif. - Several electronics manufacturers said Tuesday they are working to create a worldwide standard for how their devices will talk with each other in people's homes.

The effort, launched by Infineon Technologies AG, Intel Corp., Panasonic and Texas Instruments Inc., is aimed at making sure everyone is on the same page when it comes to home wiring for digital entertainment such as movies, music and pictures.

The HomeGrid Forum would create standards for coaxial cable, power lines and phone lines, and certify products that meet those standards.

As more people connect computers, gaming consoles, and TVs in their homes to enjoy digital entertainment, the industry hopes to create a seamless standard so that content can be more easily used.
