  • Patent number: 7965663
    Abstract: 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.

  • Patent number: 7965837
    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.

  • Patent number: 7761092
    Abstract: 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.

  • Publication number: 20070285571
    Abstract: 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.

  • Publication number: 20070254672
    Abstract: 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.

  • Patent number: 7260714
    Abstract: 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.

  • Publication number: 20050163059
    Abstract: 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.

  • Publication number: 20040224728
    Abstract: A user device enters a power save mode in which only the physical layer of its wireless communication system and minimal logic circuitry remains on. In a first implementation the minimal logic circuitry is in the MAC or the digital portion of the radio on a communication card, and the logic monitors the 802.11 traffic indication map (TIM) to determine whether traffic for the user device exists. If it does, the user is alerted or the device is powered on. In an optimum mode the minimal logic circuitry listens for a special sequence unique to the device, and if it detects the sequence leaves the power save mode.

  • Publication number: 20040177167
    Abstract: According to one embodiment of the invention, a system is provided which includes a server and one or more clients that are connected to the server via one or more power lines. The server stores audio data recorded on multiple recording units (e.g., CDs) and corresponding information associated with the respective audio data (e.g., title, author, content list, etc.). The one or more clients access the server via the one or more power lines to download selected audio data and the corresponding information from the server.
