Microsoft and Intel will team up to bring streaming audio and video to 3G (third-generation) and 2.5G phones, the companies announced Tuesday. The two companies will optimize Microsoft's Windows Media Audio Video and digital rights management software for Intel's XScale microarchitecture for wireless devices. Using this technology, cell phone users will be able to send and receive digital audio and video, Intel and Microsoft said in a joint statement. Windows Media will be optimized for Intel's processors by incorporating a set of low-level software tools for the development of advanced multimedia applications. The software, called Intel IPP (Integrated Performance Primitives), uses assembly language routines to make the best use of Intel processors. IPP can also reduce battery consumption and also help developers by allowing an application to be easily ported to multiple Intel processors, the companies said in the statement. Microsoft and Intel will also use the Intel IPPs to optimize Windows Media for the Intel StrongARM SA1110 and the Pentium 4. The StrongARM is the processor used in some handheld devices, including Compaq Computer's iPaq PocketPC.
