Intels Viiv and Advanced Micro Devices Live dual-core processor architectures put the companies at the forefront of efforts to make the PC the center of the home entertainment network of the future. The two processors are similar in that both run Microsofts Windows Media Center operating system, and they feature advanced audio and video chips, and enhanced network and storage functions. However, Viiv may present limitations for system OEMs because it requires Intel-brand audio, video, networking, and storage components. Intel claims that third-party products may be incompatible, although it is helping portable device makers to certify their products for use with Viiv. In contrast, AMDs Live requires only the companys Socket AM2 motherboard and one of the companys dual-core processors. OEMs can use any audio, video, or other component that meets AMDs performance specifications. Intel has partnered with DirecTV, MTV, Yahoo!, ESPN, and other entertainment industry leaders to ensure that their content runs well on Viiv. For example, Intel and DirecTV will allow programs to be shared from a set-top box to other devices around a home. Both AMD and Intel are working on PC tuners allowing DirecTV programming to be viewed on a PC, notebook computer, or handheld device. AMD and set-top box chip maker STMicroelectronics are developing a system that delivers Web applications to TVs in a way that makes the Web content easy to navigate.
