Abstract:
A system and method for effectively implementing a charging base for a remote control includes a television device that is controlled by the remote control over a wireless RC-TV communications link. The charging base recharges a battery of the remote control when the remote control is docked to the charging base. In addition, the remote control may be docked to the charging base for bi-directionally communicating with the television and other external entities over a wireless base-TV communications link. Furthermore, various compatible peripheral devices may also recharge their batteries and bi-directionally communicate with the television and the external entities over the base-TV communications link while the peripheral devices are docked to the charging base.
Abstract:
Remote control of an electronic device is achieved by retrieving a description of a control surface associated with the electronic device, rendering a graphical representation of at least portion of the control surface on a screen in accordance with the description and navigating the graphical representation using a navigation device that is remote from the first electronic device. The graphical representation may include multiple controls. The electronic device is operated in accordance with controls selected using the navigation device. The graphical representation may be displayed on the navigation device or on a remote screen. The controls to be displayed may be selected automatically dependent upon a selected operating mode.
Abstract:
An input system for a TV remote control or other system has a single touch surface with a deformable haptic assembly below the touch surface such that a user placing a finger on the touch surface can feel deformation of the haptic, assembly. A pressure sensing assembly is below the haptic assembly and sensing motion of a finger on the touch surface, with a processor receiving input from the pressure sensing assembly and providing output to the haptic assembly in response. Also, a display receives input sent by the processor in response to input from the pressure sensing assembly to cause the display to present a changing image of a keypad as a user moves a finger on the touch surface.
Abstract:
In a home system in which a TV receives video from various sources over directional wireless links such as 60 GHz links, a mirror apparatus is provided that can be configured to physically steer a signal toward a receiver on the TV to optimize received signal strength. In this way, RF energy that otherwise would be radiated in non-productive directions away from the receiver is reflected toward the receiver.
Abstract:
In response to a channel change command in a home network, to reduce latency a real time network bandwidth determination is made and if the determination indicates that bandwidth is sufficient to support only I-frame transmission, then only I-frames are sent temporarily from the source to the sink. Otherwise, I and P frames only are sent and may be encoded at a faster than normal frame rate and displayed at a lower than normal frame rate. If the sink is not configured for non-standard groups of pictures (GOP) some of the P frames can be indicated to the sink as being B-frames.
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.
Abstract:
The present invention relates to a system and method that allows a user to transfer digital data to and from a mobile device between two or more communication devices, in cases where the communication between the devices is restricted or otherwise limited to audio or audio tone transmissions. Transmitting digital data over such an audio communication link may include establishing a wireless, short-range communication link, converting a digital data set to an audio tone sequence, converting the audio tone sequence to a digitized audio signal, transmitting the digitized audio signal from a first device to a second device over the communication link, converting the digitized audio signal back to the audio tone sequence, and converting the audio tone sequence back to the digital data set.
Abstract:
Antenna arrays are calibrated by providing one or more test signals from the antenna array to be calibrated to a receiving sensor while varying ambient operating conditions over some predetermined range of ambient operating conditions. The signal properties of these test signals may be measured by the receiving sensor or associated spectrum analyzer, and the ambient operating conditions under which the test signals are provided may be similarly measured. Thereafter, signal offsets for each of the antenna array's elements may be determined as a function of the measured ambient operating condition. Calibration information corresponding to these signal offsets may then be stored in a memory of the antenna array for use during operation of the antenna array. This calibration information may be in the form of a lookup table or a curve-fitting equation.
Abstract:
A system and method for effectively determining a current physical location of a remote control device includes a television device that is configured to receive television control information over an RC-TV communications link. The remote control device transmits the device control information over the RC-device communications link for controlling various functions of the television device. In situations in which the current physical location of the remote control device is unknown, a system user may initiate a location search procedure with a search trigger event to locate the remote control device. The remote control device then generates one or more location indicators in response to the search trigger event to thereby facilitate determining the current physical location of the remote control device.
