A method of transmitting image data in a safety sensor or in a safety system is provided, in which transmission errors are recognized in that meta information is added to the image data prior to the transmission and the meta information is checked after the transmission. The image data are here transmitted by an unsafe communication link, in particular a black channel, the meta information is prepended and/or appended to the image data and/or to the partial packets, and the meta information comprises a piece of information on the structure of the image data.

The present application provides a video signal identification method and apparatus, an electronic device and a readable storage medium. The method includes: reading a first register to obtain a format value of a video signal received (S100); in a case that the format value is shared by target video signals with multiple formats, configuring a second register according to at least one of the multiple formats for the target video signals, and detecting whether the video signal received is in a locked state (S110); and in response to configuring the second register according to a first target format and detecting that the video signal received is in the locked state, determining that a format of the video signal received is the first target format (S120).

A video switching system, which can be part of an audio video receivers (AVR), enables simultaneous routing of multiple independent video streams (e.g., 8K video streams) received at HDMI inputs of the AVR from digital media sources to multiple selected digital display devices.

A recording device for a recording of a serialized image data stream from a sensor device. The recording device comprises a deserializer for deserializing the image data stream. To configure the first deserializer, the recording device comprises a configuration device, which records a configuration data stream transmitted by a receiving device for the purpose of configuring a serializer arranged in the sensor device and derives a configuration of the deserializer of the recording device by an analysis of the recording of the configuration data. In an example, the derivation takes place by an abstraction of the configuration of the serializer into a functionality of the serializer, a derivation of a functionality of the first deserializer from the functionality of the first serializer, and a concretization of the functionality of the first deserializer into a configuration of the first deserializer.

An electronic device is provided. The electronic device may include a wired communication interface connected to a display device through a cable, and a controller that transmits a test signal, which includes specified data, to the display device through the wired communication interface and receives error check information regarding the test signal from the display device through the wired communication interface. The controller may sequentially change transmission characteristic values of the test signal within a specified range to transmit a plurality of test signals, and perform calibration for changing a transmission characteristic of a signal to be transmitted to the display device based on the error check information regarding the plurality of test signals.

The present disclosure may relate to systems and methods for camera synchronization. A method may include determining a frequency difference between a first frequency of a first camera and a second frequency of a second camera. The method may also include synchronizing the second frequency of the second camera to the first frequency of the first camera based on the frequency difference. The method may further include directing the first camera and the second camera to execute camera operations under synchronized frequency.
