摘要： HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion. Exemplary simple embodiments of the present invention in an HDMI cable can dramatically improve audio fidelity in existing home entertainment systems without an upgrade to expensive major equipment replacement such as the source (audio system) or sink (Television).

摘要： Digital data, including audio and video, may be communicated at increased data rates by utilizing non-data signal channels in cables to communicate additional data. For data transmission, a reformatter receives data in a first format adapted for communication over the data signal channels of a cable. The reformatter may convert the received data into a second format with one or more additional data signals. The reformatter then utilizes non-data signal channels of the cable to carry the additional data signals. An example non-data signal channel may include a clock signal channel, and the reformatter may fold a clock signal into one or more of the data signals to allow for clock recovery downstream. Data may also be split into two or more subsets and each subset encoded separately, for example with two or more data encoders such as legacy HDMI encoders.

摘要： Signals propagating on an aggressor communication channel can cause detrimental interference in a victim communication channel. A signal processing circuit can generate an interference cancellation signal that, when applied to the victim communication channel, cancels the detrimental interference. The signal processing circuit can dynamically adjust or update two or more aspects of the interference cancellation signal, such as an amplitude or gain parameter and a phase or delay parameter. Via the dynamic adjustments, the signal processing circuit can adapt to changing conditions, thereby maintaining an acceptable level of interference cancellation in a fluctuating operating environment. A control circuit that implements the parametric adjustments can have at least two modes of operation, one for adjusting the amplitude parameter and one for adjusting the phase parameter. The modes can be selectable or can be intermittently available, for example.

摘要： Systems and methods reduce electromagnetic interference from high speed data carried by wired interconnects with a radio receiver for at least one protected radio frequency band. A spectral encoder changes the encoding of the high speed data to modify its frequency spectrum and reduce its spectral in the protected frequency band. The wired interconnect carries the spectrally encoded data to its destination, where it is spectrally decoded back to its original form. Spectral encoding may include polynomial scrambling. The data may be encoded with different coding parameters in parallel and the best result selected for communication over the wired interconnect. The coding parameters may be changed depending on which radio receivers and/or protected frequency bands are in use at any given time.

摘要： A noise-reduction system includes a noise-pattern predictor in communication with a noise-canceling module. In a more specific embodiment, the noise-reduction apparatus further includes an input collector in communication with the noise-pattern predictor. The input collector is coupled to a first module, such as a sensor, that provides information to the noise-pattern predictor to facilitate predicting noise in an accompanying signal environment and to provide a first signal in response thereto. In an illustrative embodiment, the first signal includes information indicating when an ignition system of a vehicle will turn on. The first signal further includes information indicating when a second signal transmitted from a cellular base station will affect noise in the signal environment. The second signal may include a burst in a cellular signal.
