Realtek Semiconductor will participate in the globally acclaimed top technology event — the 2024 Embedded World in Nuremberg, Germany, from April 9th to 11th. This exhibition, attracting professional audiences from 75 countries, is an eagerly anticipated annual international feast for cooperation and exchange. Realtek will showcase comprehensive communication network solutions for all applications, covering a wide range, and including automotive chips, Wi-Fi 7 routers, industrial-grade Ethernet switches, PON SoCs, Bluetooth, and IoT solutions. Each exhibit embodies the pursuit of network communication technology, with solutions also integrating AI intelligent applications to provide efficient technical support for smart products.

Recently, the amount of Bluetooth devices that support A2DP source/ HFP capability has grown dramatically. Nowadays, most users might have multiple devices, such as mobile phones, tablets, soundbars, TV sets, game consoles, etc. (Please refer to Figure 1 / Figure 2.) Simultaneously, the TWS earbud is now the most popular audio/voice sink device. If solution vendors can provide an easier way of creating/maintaining connections and smoothly switching between source devices, it will end up helping users significantly. Thus, Multilink, called Multi-connection, became a mandatory capability in Earbud.
