InterVideo InstantON is a new software solution that leverages the reliability and power of InterVideo LinDVD , the playback/navigation software selected by companies such as SONY, Pioneer and others for their high-end CE devices. The Instant Media Technology (IMT) technology incorporated in the new Linux勠based software integrates the BIOS, OS, power management, and noise control with InterVideo's media playback/recording/editing technology, enabling consumers to enjoy the Instant access and remote control-only CE experience on their PC.
After a brief boot-up in Linux (about 10 seconds), all of the CE-type activities consumers have come to expect from a complete home entertainment center can be accessed. With InterVideo InstantON's dual-boot configuration, users can move into the Windows mode (which requires the full Windows load time) when they want to use the PC to access their work-related files.
