Multimedia Codecs
Multimedia Codecs are essential tools that help infotainment systems play different types of audio and video content in vehicles. Think of them as translators that convert music, videos, and other media into formats that car entertainment systems can understand and play. Just like different countries have different languages, various devices and media files use different "languages" to store audio and video. Codecs make sure everything works smoothly together, whether it's playing music from a phone through the car speakers or showing videos on rear-seat entertainment screens.
