Microsoft has submitted Windows Media 9 – its latest video and audio codec – to the society of Motion Picture and Television Engineers (MPTE) for review, reports Reuters.

The company hopes to see Windows Media 9 recognized as a standard. This would enable other companies to build products based on it. MPTE approval is a prerequisite of this goal, and could take up to 12 months.

Microsoft's Windows Media 9 plans reflect Apple's open-standards approach with QuickTime, and industry watchers say it marks an intensification of the multimedia-format battle.

Windows Media 9 is currently employed by Mac user Peter Gabriel's OD2 network in order to provide songs to digital music download services.

A report yesterday revealed Microsoft to be preparing a version of Windows Media 9 for Mac OS X.
