Ethernet AVB
Ethernet AVB (Audio Video Bridging) is a technology used in modern vehicle entertainment and information systems. Think of it as a special way to connect different parts of a car's entertainment system, ensuring that music, video, and other media play smoothly without delays or interruptions. It's like having a very reliable digital highway inside the car that makes sure all audio and video data reaches its destination at exactly the right time. This technology is particularly important in luxury vehicles and advanced infotainment systems where high-quality audio and video performance is crucial.
