With a roster of heavy-hitters that already included Sony Ericsson, Nokia, Motorola and Intel, the DVB-H alliance was quickly shaping up as the 800-pound gorilla of the mobile media world. Now that Microsoft has signed on, we assume that it's pretty much game over for just about any other video-on-the-go standard. Of course, given that Windows Media technology has already been used by companies like Modeo in DVB-H trials, Microsoft's support should come as no surprise. But as Modeo president Michael Schueppert says, Microsoft's clout will "accelerate the introduction of mobile digital television based on DVB-H into cell phones, PDAs, laptops and portable media players." Indeed.
