TiVo is expanding its video recording service so users will be able to transfer recorded television shows onto Apple Computer’s iPods or Sony’s PlayStation Portable–the latest move aimed at putting TV in people’s hands for viewing anywhere. The enhanced TiVoToGo feature will also add more copy-protection measures to discourage possible copyright abuse that would anger Hollywood. TiVo officials said shows recorded via TiVoToGo will have digital watermarks. The extra encoding will follow the copied program wherever it goes, giving TiVo the ability to trace the origin of a transferred program that might get posted freely onto the Internet.
