摘要:
A remote controller for a mobile device is described. The remote controller includes a communications transceiver configured for bidirectional communications with the mobile device, and a computer processing system communicatively coupled to the communications transceiver. The computer processing system may be configured to execute instructions to remotely control one or more applications associated with the mobile device. Examples of applications include media playback applications, software updating applications, and the like. The remote controller may also include one or more actuators communicatively coupled to the computer processing system, the one or more actuators being configured to receive user input to control or access the one or more applications. Additionally, the remote controller may include a screen.

Provided are devices and methods for transmitting two or more data streams through the same cable. An exemplary cable includes at least two sets of conductive points, each set capable of independently transmitting a separate data stream. The cable may be a USB 2.0 type cable, with two contacts assigned for transmitting one data stream, and two other contacts assigned for transmitting another data stream. In some embodiments, one data stream is an audio-video signal transmitted to an audio-video receiver.

Signaling and coding methods and apparatus for long-range 10 and 100 mbps Ethernet transmission. In accordance with the method, a physical layer (PHY) device is provided that includes the long-range capabilities. In operation, the PHY measures the distance to a companion PHY, and if it is within the specification limits, communicates with the companion device in the normal way. If the distance is above the specification limits, the PHY checks to see if the companion PHY is similarly enabled, and if so, switches to a long-range signaling method. In a preferred embodiment, NRZ coding with pre-emphasis on the first bit of two or more bits of the same value is used for a first range exceeding the specification limit, and PAM4 coding is used for a second range exceeding the first range. Various embodiments are disclosed.

Systems and methods for charging a mobile device using a high-speed data interface are described. Power may be provided from Transition Minimized Differential Signaling (TMDS) lines when TMDS data is transmitted via a High-Definition Multimedia Interface (HDMI) connection between a transmitter, such as a mobile device, and a receiving device. Power may be provided to the mobile device in exemplary embodiments such that when the transmitter is in idle or power down state, power may be provided from TMDS lines as part of an upstream charging function.

Provided are methods for transmitting two or more data streams through the same cable. The cable includes at least two sets of conductive points, each set capable of independently transmitting a separate data stream. The cable may be USB 2.0 type cable. Pins 2 and 3 may be assigned for transmitting one data stream, while pins 4 and 5 may be assigned for transmitting another data stream. For example, one data stream may be audio-video signal transmitted to an audio-video receiver.

A delay locked loop (DLL) includes a delay line that delays a clock signal to generate a delayed clock signal, a phase frequency detector (PFD) for detecting a phase and/or frequency difference between the clock signal and the delayed clock signal, and a charge pump having an adjustable bias current for converting the phase and/or frequency difference taking into account a bias current adjustment into a control voltage, in which the control voltage controls an amount of delay in the delayed clock signal.

High-Definition Multimedia Interface Specification, Version 1.2, supports multiple video formats. Currently the HDMI sources and sinks support multiple formats through reconfiguration of the system. The present invention describes the use of a configurable ‘n’בn’ data pixel mapping matrix for video format conversion. This mapping matrix allows the mapping of any existing video format to any other existing or future video format and allows flexibility of connectivity to any transmitter or receiver. Accordingly a more user friendly implementation that provides greater flexibility for development and use of new formats in video applications is shown.

Embodiments include systems and methods of powering a mobile device using a sink device. The method may include detecting a coupling of a mobile device to the sink device and transmitting an acknowledgement in response to a query, the acknowledgement confirming that the sink device has charging capability. Power may be selectively provided in response to the power request. According to some embodiments, the method includes transmitting a query by a communications transmitter to determine if a sink device has charging capability, and deactivating a driver for a power line and transmitting a power request using the communications transmitter in response to receiving an acknowledgement signal from the sink device. The method may further include selectively providing power received from the sink device to a charging circuit of the mobile device. The mobile device may include an HDMI transmitter for communicating through a transmission line to an HDMI sink device.
