videovärk

Videovärk refers to a type of electromagnetic interference (EMI) that can damage electronic devices, particularly those with video systems in vehicles. It occurs when a vehicle's electrical systems and wiring react to emissions from other electronic devices, such as radar and communication equipment.

This form of EMI can cause interference to the vehicle's video system, resulting in various issues, including pixelation, static, and complete loss of video signal. In severe cases, it may also affect other electronic systems in the vehicle, such as navigation and audio equipment.

The term videovärk is primarily used in Nordic countries, particularly in Sweden and Denmark. It literally translates to "video disease" in English, although it is a physical phenomenon rather than a disease.

Videovärk can be caused by a variety of factors, including the electromagnetic radiation emitted by other devices, the presence of faulty or poorly designed wiring in the vehicle, and the use of low-quality electronic components.

To mitigate the effects of videovärk, vehicle manufacturers and users can take several steps, including using shielded cables, installing filters or interference suppressors, and selecting electronic components with built-in EMI protection. In some cases, software updates or reconfiguring the video system settings may also be necessary to minimize interference. By taking these measures, drivers can reduce their exposure to videovärk and maintain the reliability of their vehicle's electronic systems.
