Sprint is adding a television service for cell phones with real-time programs from cable networks. CNN reports that the new MobiTV service, available starting this week, will cost $9.99 per month in addition to the monthly fee of $15 that Sprint subscribers pay to use the Internet data connection on their mobile phones. Although the audio for MobiTV programs will play in a continuous stream, the cell phone screen will not display the equivalent of full-motion video like that seen on a real television. Instead, the video will play at a rate of one or two frames per second, as compared with more than 20 frames per second for real TV.
