Abstract
A novel handheld media and communication device with a detachable projector is disclosed. Both of the units comprise a wireless network interface. The detachable projector unit further comprises a processor, a file system, a cache, a projector and a power supply. The media files are copied into the file system of the projector unit before it is detached from the media and communication device that is then used as a remote control for the detached projector unit. The control is achieved by transmitting the metadata from the media and communication device to the projector unit to retrieve the associated media files for the projection. Further, a novel method for sharing a video/audio files by a group of users with handheld devices in a synchronized manner is disclosed. The devices form a local wireless network with calibrated built in clock in each device. The video and audio signals are assigned with a starting time for playing. The audio files are broadcasted to the local wireless network and received by each user'"'"'s connecting device while the video files are sent to the projector for the projection. The video and audio files are played in a synchronized manner based upon the calibrated clocks. An expandable projector device with a plurality of projectors connected sequentially is also disclosed. The additional power supply and media files can be shared by the projector unit under the projection operation thus a much longer media sharing time can be achieved by portable devices.
