1. A system, comprising:
- a source of multimedia data; and
a displayer of multimedia data mounted in a room in which the source is disposed, the source wirelessly transmitting the multimedia data in an uncompressed form to the displayer on a primary link at approximately sixty GigaHertz (60 GHz), wherein the primary link has a data rate of at least two Giga bits per second (2.0 Gbps) and the primary link has a bandwidth of approximately 2.5 GHz, the source and displayer not being disposed together in a common package, wherein the displayer sends to the source capability signals on the primary link to adjust a directivity of an antenna beam transmitted by the source, wherein displayer control signals are multiplexed with the multimedia data on the primary link such that the audio and video display functions of the displayer can be controlled at the source.

Abstract
High definition (HD) video may be sent from, e.g., a laptop computer on a table in a room to a video projector mounted on the ceiling using a 60 GHz high capacity (2.5 Gbps) 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 and the HD video display is necessary.

8. A method for transmitting multimedia data, comprising:
-
disposing a multimedia transmitter and a multimedia receiver in a room on different surfaces from each other; establishing a wireless link between the transmitter and receiver; and wirelessly transmitting a multimedia signal on the link from the transmitter to the receiver at a frequency sufficiently high that the signal substantially cannot be received outside the room, signals being exchanged between the transmitter and receiver, wherein player control signals multiplexed in the multimedia are sent between the transmitter and receiver, at least some control signals being useful for establishing a transmitter antenna beam control, the control signals being such that audio and video display functions of the receiver can be controlled at the transmitter. - View Dependent Claims (9, 10, 11, 12)
