A multimedia audio/video system includes a multimedia audio/video transmitting end and a multimedia audio/video receiving end. The multimedia audio/video transmitting end includes a multimedia data generator and a first data converter. The multimedia data generator is used to generate a multimedia data conforming to a first transmission protocol. The first data converter is used to convert the multimedia data conforming to the first transmission protocol into a multimedia data conforming to a second transmission protocol. The multimedia audio/video receiving end includes a second data converter which is used to convert the multimedia data conforming to the second transmission protocol into the multimedia data conforming to the first transmission protocol. The multimedia data conforming to the first transmission protocol is transmitted via multiple cables, while the multimedia data conforming to the second transmission protocol is transmitted via a single cable.

A method is provided for transmitting high-definition video. A device used electrically connects to graphics processing units (GPU) and a network switch. Each GPU comprises a circuit board, video transmission interfaces, Internet protocol interfaces, and a mobile peripheral-component-interface-express module (M×M) video chip module. The M×M video chip module is designed as industrial standard M×M. Only a circuit board is required for video transmission. Based on specifications of software defined video over ethernet (SDVoE), video signals of the second version of high definition multimedia interface are transformed onto an IP network with no time delay and no compression while fabricating a video card of SDVoE output. GPUs can be replaced through generations no matter how M×M is changed. By replacing the M×M video chip module without redesigning the whole video card, resources waste is effectively decreased with energy saving and carbon reduction.

A device can include a video cable that includes opposing ends; and a human presence sensor operatively coupled to the video cable between the opposing ends.

A system includes a downstream facing port (DFP) coupled to a video source, an upstream facing port (UFP) coupled to a video sink, and a cable. The cable includes a first end that is connected to the DFP and a second end that is connected to the UFP. The cable is configured to carry a differential auxiliary transmission signal and detect polarity in the differential auxiliary transmission signal.

Infrastructure electronics equipment incorporates infrastructure Local-Site Transports (LSTs). LSTs convey payload sampled signals over imperfect electromagnetic (EM) pathways whose physical properties are usually unknown when the equipment (e.g., Cameras, Displays, Set-Top Boxes) is manufactured. Prior LSTs hedge against EM pathway degradation in several ways: requiring high-quality cables (e.g., HDMI); restricting transmission distance, (e.g., HDMI); and/or reducing quality, via compression, to extend transmission distance somewhat (e.g., Ethernet). The subject of this disclosure is an infrastructure LST for sampled signals that causes the physical errors inevitably arising from propagation of sensory payloads over imperfect EM pathways to manifest in a perceptually benign manner, leveraging legacy infrastructure and reducing costs to achieve a favorable ratio of fidelity to transmission distance.

Described herein are systems and methods that provide for asymmetric image splitter image stream applications. In one embodiment, a system supporting image multi-streaming comprises an asymmetric image splitter engine that splits super-frame image streams into two or more image streams and a fractional clock divider circuit. The fractional clock divider may comprise a digital feedback control loop and a one-bit sigma delta modulator. The fractional clock divider circuit may provide compatible display clock frequencies for each of the two or more image streams. When a multi-image stream comprises the two image streams, the asymmetric image splitter engine adjusts a vertical asymmetry of a first image stream with a shortest height to same height as a second image stream by adding vertical padding to the first image stream. The super-frame image streams may comprise image streams from video, LIDAR, radar, or other sensors.

A household appliance has a sensor module and a control unit which are connected to one another via a cable harness containing a cable to supply power to the sensor module and to transmit data. The sensor module is connected to the control unit via an FDP-link III-compatible or GMSL-compatible connection which contains a serializer which is associated with the sensor module, a deserializer, and a cable harness which connects the serializer and the deserializer. A method is used to operate the household appliance, in which, sensor data generated by the sensor module are translated into FPD-link III-compatible serial data by the serializer of the FPD-link III connection. The serial data are transmitted via the cable harness to a deserializer and are back-translated therein, and the back-translated sensor data are transmitted to the control unit. The method is used in refrigeration appliances having cameras for recording images.
