Abstract:
A method and apparatus for downloading auxiliary data to a client during idle periods and for displaying the auxiliary data while the client is fetching information from the network is disclosed. According to one embodiment of the present invention, the state of a client device is first determined, wherein the client device is in a fetching state while processing a user request and the user is waiting or in an idle state while not processing a user request and the user is not waiting for the client system. Auxiliary data is then downloaded from a server to the client device when the step of determining determines that the client device is in an idle state. Additionally, the downloaded auxiliary data is buffered in an auxiliary buffer. The auxiliary data is then processed to generate an output and the output is displayed on the client device while the client device is in a fetching state.
Abstract:
The present invention describes a method for transmitting high bandwidth network content on a low bandwidth communications channel during off peak hours. According to one embodiment of the present invention, criteria is determined for downloading data from the communications channel and the data is downloaded from the communications channel during off-peak hours based on the determined criteria. According to another embodiment, a method for coordinated multicasts on a network is described. Download requests are received on a server from a plurality of clients on the network and stored on the server for the coordinated multicast. The coordinated multicast is generated at a predetermined time and then broadcast from the server to the plurality of clients at the predetermined time.
Abstract:
A low power, single master, variable clock rate, daisy-chainable, serial bus connects a bus dispatch (master) to a chain of one or more daisy-chained peripheral devices (slaves). The bus has a bidirectional serial data line, a bidirectional clock line, unidirectional interrupt line, power and ground lines. All bus transactions over the bus occur under bus dispatch commands. If a peripheral device interrupts the bus dispatch, bus dispatch issues commands over the bus to determine which device caused the interrupt and what service is being requested by the device. The bus dispatch may then turn control of the data and clock lines over to the peripheral device for a limited amount of time depending on the service requested. New peripheral devices can be connected onto the bus and unused peripheral devices can be disconnected from the bus while the bus is operating without causing a bus failure. Similarly, bus dispatch may enter a low power sleep mode from which it may be awakened by a peripheral device. In some embodiments, additional lines such as battery charging lines and/or signal lines for other serial buses such as RS-232 and RS-422 are provided.
Abstract:
A video display apparatus for composing video signals for a raster scanned display on a line-by-line basis. Objects are stored in a video RAM and are packed in the RAM without regard to their location on the display. A separate dispatch table contains information on each object and commands. A dispatcher operates on this information, allowing lines of data and commands to be extracted from the RAM as each video line is composed in a buffer.
Abstract:
An apparatus and method is disclosed for reducing flicker in an interlaced computer generated raster-scanned display. Several circuits and methods are described for implementing vertical filtering. In general, the data for a given pixel on the nth, nth+1, nth+2 . . . nth+N line is read from memory and convolved to provide data for a given pixel on a display line before pixel data for other pixels along these lines is read from memory.
Abstract:
A system and method are described for distributed antenna wireless communications. For example, a method implemented within a wireless transmission system comprised of a plurality of wireless client devices and a plurality of distributed antennas is described comprising: computing channel state information (CSI) for wireless communication channels between the plurality of base distributed antennas and the wireless client devices; computing precoding weights from the channel state information; precoding data using the precoding weights prior to wireless transmission from the plurality of distributed antennas to the wireless client devices; and wirelessly transmitting the precoded data from the distributed antennas to each of the wireless client devices, wherein the precoding causes radio frequency interference between the plurality of base stations but simultaneously generating a plurality of non-interfering radio frequency user channels between the plurality of distributed antennas and the plurality of wireless client devices.
Abstract:
A system and machine-implemented method are described for adjusting communication with a first distributed-input-distributed-output (DIDO) client. For example, a method according to one embodiment of the invention comprises: applying DIDO weights to one or more data streams to generate one or more DIDO precoded data streams; receiving input channel quality information (CQI) and/or channel state information (CSI) related to DIDO communication channels over which the DIDO precoded data streams are to be transmitted; determining a power scaling factor based on the CQI and/or CSI; and applying the power scaling factor to each of the DIDO precoded data streams.
Abstract:
A system and method for entering text within a video game application are described. For example, a system according to one embodiment of the invention comprises: a video game hosting service to execute a video game in response to user input; a client device to communicate with the video game hosting service over a first communication channel, wherein the client device has a first user input device communicatively coupled thereto, and wherein control signals for the video game are generated in response to input from the first user input device and transmitted from the client device to the video game hosting service over the first communication channel, the video game hosting service controlling a video game in response to receipt of the control signals; a display device communicatively coupled to the client device, the display device to display video of the video game; wherein the video game hosting service further includes program code to open a second communication channel to receive text input, the second communication channel being separate and independent from the first communication channel and usable by a data processing device capable of generating text input, wherein in response to receipt of text input over the second communication channel, the video game hosting service causes the text input to be displayed on the display device communicatively coupled to the client device.
Abstract:
A computer-implemented system and method are described for managing audio chat for an online video game or application. For example, a system according to one embodiment comprises: an online video game or application execution engine to execute an online video game or application in response to input from one or more users of the video game or application and to responsively generate audio and video of the video game or application; and a chat subsystem to establish audio chat sessions with the one or more users and one or more spectators to the video game or application, the chat subsystem establishing a plurality of audio chat channels including a spectator channel over which the spectators participate in audio chat and a user channel over which the users participate in audio chat.
Abstract:
A computer-implemented system and method are described for performing video compression. For example, a method according to one embodiment comprises: encoding a plurality of video frames or portions thereof according to a first encoding format; transmitting the plurality of encoded video frames or portions to a client device; receiving feedback information from the client device, the feedback information usable to determine whether data contained in the video frames or portions has not been successfully received and/or decoded; in response to detecting that a video frame or portion thereof has not been successfully received and/or decoded, encoding a video frame or portion thereof according to a second encoding format; and transmitting the video frames or portions thereof to the client device.
