METHOD AND SYSTEM FOR WIRELESS DIGITAL VIDEO PRESENTATION

摘要

High definition (HD) video maybe sent from, e.g., a laptop computer (12) on a table (14) in a room (16) to a video projector (20) mounted on the ceiling (26) using a 60 GHz high capacity (2.5Gbps) wireless link. At this frequency and data rate, the signal is so short range and directional that low power may be used and the video may be transmitted in an uncompressed form such that so much data is transmitted each second that bootlegging the content is essentially untenable. No wiring between the HD video source (12) and the HD video display (20) is necessary.
