Digital Visual Interface (DVI), or High Definition Multi-media Interface (HDMI), data is received from a source and sent to a transmitter chip that includes a transition minimized differential signaling (TMDS) receiver that outputs a 3-data and 1-clock physical signaling stream representing the DVI or HDMI data. This stream is rendered into I and Q data by an ASIC or FPGA and sent to a wireless transmitter for modulation, upconverting, and transmission to, e.g., a nearby display device without ever rendering the data into baseband video on the transmitter chip. The display device has a receiver chip that is essentially the inverse of the transmitter chip.

Method and system for wireless digital multimedia transmission

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.

Method and system for wireless digital video presentation

A system and method are disclosed that accepts different types of signals from multiple sources and routes the signals to the appropriate devices for conversion or other processing so that each signal is in a common or desired format, such as the MPEG standard. The individual signal streams are packetized so that each signal stream carries identifying information associated with it originating signal source and then multiplexed onto a single digital transport stream for storage. Such a system allows overlapping signals of different types from multiple sources to be processed and stored in a single storage device. Each of the signals can then be subsequently retrieved for playback or display.

Multiple source recording

Disclosed are systems and methods for communicating with multiple devices. In one embodiment, a plurality of wireless devices in close proximity are able to transmit data at a high rate using a secure connection. While in one embodiment this data is transmitted using a high speed, directional signal at a 60 GHz frequency. In a further embodiment, data is transmitted at a 60 GHz frequency between a personal computing device and a plurality of consumer electronic devices that are in relative close proximity to one another. The directional nature of this high frequency signal permits a large number of devices in a close proximity to communicate without interfering with each other. Moreover, the directional nature of such a high frequency signal provides added communications security since the receiver will typically be in the line of sight of the transmitter.

Disclosed is a system, apparatus, and method for dynamically estimating the bandwidth of a network link in a wireless network. The system includes at least one client device capable of receiving data over the wireless network and a server capable of transceiving data over a link of a wireless channel of the wireless network. The server identifies the at least one client device in the wireless network and identifies applications that are being utilized in the wireless network by the at least one client device, in which each application has an associated link between the server and the client device and an associated data stream transmitted over the link. The server passively estimates the bandwidth being used by an application over the link based upon measuring the throughput of the associated data stream and based upon determining channel utilization of the link.

Disclosed is a system, apparatus, and method for dynamically allocating wireless channels in a wireless network. At least two client devices are present in the wireless network. Each client device is capable of transceiving wireless data over a wireless channel. In one embodiment, a server capable of a transceiving wireless data over at least one wireless channel determines the number of client devices in the wireless network. The server allocates client devices to different wireless channels. Particularly, client devices that receive data at substantially different data rates are allocated to different wireless channels in order to optimize the total system utility of the wireless network. Furthermore, client devices that receive data at substantially similar data rates are allocated to the same wireless channel.

A wireless component is authenticated to an in-home wireless entertainment system server by simultaneously or near-simultaneously holding down buttons on the component and server and transmitting a component ID (or encryption results generated from the key) to the server. The server then indicates 'authenticated', and the component can subsequently access the system using its ID.

One aspect of the present invention relates to a system and method for selecting the sources of at least two shows capable of being received and displayed by an entertainment system. The user selects for viewing, a first show associated with a first channel from a first source. The first show is then displayed. The user also selects for viewing, a second show associated with a second channel from any one of the first and a second sources. The second show is then displayed. A second aspect of the present invention relates to a system and method for selecting the sources of at least two shows capable of being received and displayed by an entertainment system. The user selects for viewing, a first show associated with a first channel from a first source. The first show is displayed on a first portion of a display screen. The user also selects for viewing, a second show associated with a second channel from any one of the first and a second sources. The second show is simultaneously displayed on a second portion of the display screen.

An apparatus comprising a plurality of columns bound together, configured to display a single row of pixels scanned out from top to bottom. It also comprises a timing control unit to synchronize between the columns to allow all pixels of a single row to be lit at the same time.

Flat moldable HDTV display

An adapter having a slot, a connector, and a passive router that routes signals from a smart card inserted in the slot to the connector, is disclosed.

Interfacing an NRSS-A smart card within an NRSS-B PCMCIA

A system for monitoring the proximity and location of a child by a parent includes two transceiver units which communicate wirelessly. The child unit will transmit a signal to the parent unit so that the parent unit can determined the proximity of the child unit and its direction. A safe zone may be set by controls on the parent unit. When the child unit moves beyond the safe zone, the parent unit will generate an alert.
