In a major step in its efforts to deliver subscription-based music and video content for portable and networked devices, the company has unveiled the next version of its Windows Media digital rights management (DRM) software. Numerous online music and movie services, entertainment companies, and consumer electronics firms have lined up to support the software, code-named Janus. The new DRM software has a "time bomb" feature, which will allow users to rent music and movies only for short periods. The idea is that "you will be paying a low monthly fee to fill your portable music player with thousands of songs, or renting a dozen movies to take with you on a Portable Media Center," says Amir Majidimehr, Microsoft corporate vice president.
