Abstract: A method that calibrates a device for echo cancellation and a device with calibration for echo cancellation are provided. Devices may be calibrated such that the echo residual error is less than a threshold determined by the calibration accuracy. Non-ideal factors such as mismatch may be eliminated during calibration.

Abstract: Embodiments relate to half-duplex bidirectional transmission of data compliant with a first standard (e.g., Universal Serial Bus (USB) standard) over a physical channel of a multimedia link for transmitting audio/video (“A/V”) data compliant with a second standard (e.g., Mobile High-Definition Link (MHL) standard) between a source device and a sink device using time division multiplexing (TDM). The source device sends units of data including A/V data and forward data compliant with the first standard at first times whereas the sink device sends units of data including backward data compliant with the first standard at second times between transmissions from the source device. The first times do not overlap with the second times. Synchronization signals may be added to the first and second units of data to align character symbols embedded in the first and second units of data.

Abstract: Embodiments of the invention are generally directed to compensation for common mode signal swing. An embodiment of an apparatus includes a connector for the transfer of the data, the connector including connections for a first set of one or more conductors; a receiver for the reception of data via the connector, the received data including a first signal and a second signal transmitted via the set of one or more conductors, the second signal being a common mode signal modulating the first signal, the receiver including an amplifier to amplify the received data with a positive gain; and a common mode compensation circuit to compensate for a voltage swing of the common mode signal in the amplified received data. The common mode compensation circuit is to sense the common mode signal, amplify the sensed common mode signal with a negative gain, and feed back the amplified common mode to output nodes of the receiver.
